Viruses That Can Cause Cancer

Viruses Cause Cancer

Though environmental and genetic elements play a major role in its development, certain viruses also start cancer in people; cancer is still one of the biggest causes of mortality globally. About 15–20% of all malignancies worldwide are oncogenic viruses, which reduce the load of virus-associated cancers. This depends on an awareness of the processes by which these viruses induce cancer as well as their preventability.

This piece looks at how viruses cause cancer, names some of the most common ones, and talks about ways to lessen their effects on people’s health.

How Viruses Cause Cancer?

By throwing off regular cellular functions, viruses may induce cancer. A virus may either stay as a distinct viral genome within the host cell or incorporate its genetic material into the DNA of the cell upon invading it. This procedure can:

  • Viral DNA might interfere with the cell’s capacity to govern development and division, therefore promoting unchecked proliferation.
  • Persistent infections may lead to an inflammatory condition that destroys tissues and encourages genetic changes.
  • Some viruses weaken the immune system, therefore lowering the body’s capacity to identify and eliminate aberrant cells.
  • These mechanisms provide the ground for the change of ordinary cells into malignant ones.

Main Oncogenic Viruses and Their Associated Cancers

Human Papillomavirus (HPV)

Linked with cervical cancer and various other malignancies, HPV is among the most well-known cancer causing viruses. Though there are more than 100 varieties of HPV, most cancer cases are caused by high-risk strains, including HPV-16 and HPV-18. Mostly via sexual contact, HPV may cause genital, anal, and throat cancer, as well as other forms.

Particularly if given before viral exposure, routine HPV vaccination is very successful in avoiding these malignancies.

Hepatitis B Virus (HBV)

Hepatocellular carcinoma liver cancer is mostly caused by HBV. Often, by improper injections, unprotected intercourse, or mother-to-child transmission after delivery, the virus is transmitted via contact with contaminated blood and bodily fluids. Long-term inflammation and liver damage brought on by chronic HBV infection may, over time, develop into a malignancy.

In many areas of the globe, particularly where HBV prevalence is high, vaccination against HBV has dramatically decreased liver cancer rates.

Hepatitis C Virus (HCV)

 Another major factor driving liver cancer, especially in those with persistent infections, is HCV. There isn’t a vaccination for HCV, unlike for HBV. Usually, by means of sharing needles, unsterilized medical equipment, or risky blood transfusions, the virus is transmitted via contact with contaminated blood. If managed, chronic HCV infection sometimes advances to liver fibrosis, cirrhosis, and finally, malignancy.

Improved results for those with HCV have resulted from advances in antiviral medications, therefore lowering the risk of cancer formation.

Epstein-Barr Virus (EBV)

Member of the herpesvirus family, EBV is associated with numerous malignancies, including certain stomach tumors, nasopharyngeal carcinoma, Hodgkin lymphoma, and Burkitt lymphoma. Commonly linked to infectious mononucleosis (“mono), it travels through saliva. Although most EBV infections are asymptomatic or self-limiting, in high-risk people, chronic infections may cause malignancy.

Human T-cell Leukemia Virus Type 1 (HTLV-1) 

A rare and aggressive malignancy, adult T-cell leukaemia/lymphoma (ATLL), is linked to HTLV-1. The virus gets around by infected blood products, sexual contact, and nursing. Unlike other oncogenic viruses, HTLV-1 transforms immune cells (T cells), especially into malignant cells.

Efforts at prevention centers are focused on reducing transmission through blood screening and advocating responsible behaviour.

Kaposi’s Sarcoma-Associated Herpesvirus (KSHV)

Kaposi’s sarcoma, a malignancy of blood vessel linings, is mostly caused by KSHV, often known as human herpesvirus 8 (HHV-8). Those with compromised immune systems, including those living with HIV/AIDS, are more prone to it. Apart from other uncommon diseases like primary effusion lymphoma, the virus spreads via saliva or blood contact.

Antiretroviral treatment has greatly lowered KSHV-related malignancies by helping to control HIV/AIDS.

Merkel Cell Polyomavirus (MCV)

The rare but quite significant cancer-causing virus is Merkel Cell Polyomavirus (MCV). It is linked to the severe kind of skin cancer known as Merkel cell carcinoma. Many times, this virus has been detected in the malignancies of those with impaired immune systems or heavy sun exposure. Though MCV infections are somewhat widespread, only a tiny proportion leads to cancer, usually when the virus mutates in a manner that lets it survive in cells and disturbs regular cellular control.

Although there aren’t any particular vaccinations or preventative actions for MCV right now, keeping immunological health and shielding skin from too much UV radiation can lower chances.

Prevention and Awareness

Preventive measures include vaccination, public education, and safe behaviour, which define the battle against virus-related malignancies.

Vaccines

Vaccines have been very helpful in lowering the occurrence of malignancies connected to viruses. While the HBV vaccination guards against liver cancer brought on by a persistent HBV infection, the HPV vaccination guards against high-risk HPV strains.

Safe Practices 

To stop the spread of viruses like HPV, HBV, and HCV, practice safe sex, avoid needle sharing, and guarantee correct sterilizing of medical tools. Programs for blood screening also help spot and stop the spread of these infections.

Regular Screenings

For high-risk individuals, screening frequently for early indicators of infection and related malignancies is vital. Women are urged, for instance, to have regular Pap screenings in order to detect HPV-caused cervical abnormalities.

Prevent Viruses Cause Cancer

Important causes of cancer globally include viruses like HPV, HBV, HCV, EBV, HTLV-1, KSHV, and MCV. To turn healthy cells into cancerous ones, they operate via processes including genetic disturbance, persistent inflammation, and immunological suppression. Many of these malignancies may be prevented, however, with sensible habits, immunization, and frequent screening, among other preventative strategies.

Fighting the danger of oncogenic viruses and opening the path for a better future free from avoidable malignancies depend on ongoing research and worldwide public health measures.

What is Stage 4 Cancer?

What is the Survival Rate in Stage 4 Cancer?

Stage 4 cancer is the most advanced stage of cancer. It is also known as metastatic cancer. At this stage, cancer cells have spread from the primary tumour to other parts of the body through the bloodstream or lymphatic system. This process is called metastasis.

In stage 4 cancer, the disease may have spread to distant organs or tissues, making it more difficult to treat. Treatment options for stage 4 cancer often focus on managing symptoms, slowing the progression of the disease, and improving quality of life rather than attempting to cure the cancer completely. However, depending on the type of cancer and individual factors, treatments such as chemotherapy, radiation therapy, targeted therapy, immunotherapy, and surgery may still be considered to help control the cancer and prolong survival.

How Do Doctors Stage Cancer?

Doctors use a process called staging to determine the extent of cancer within the body, which helps guide treatment decisions and provides information about prognosis. The staging system varies depending on the type of cancer but generally includes several key components:

Tumour size: The size of the primary tumour is often a factor in staging. Tumours are typically measured in centimetres and may be described as T1, T2, T3, etc., with higher numbers indicating larger tumours.

Lymph node involvement: Cancer cells can spread to nearby lymph nodes, which are part of the body’s immune system. The presence or absence of cancer in nearby lymph nodes is an important factor in staging and is often denoted as N0 (no lymph node involvement) or N1, N2, N3, etc., depending on the number and location of affected lymph nodes.

Metastasis: Metastasis refers to the spread of cancer to distant organs or tissues beyond the primary site. The presence or absence of metastasis is a crucial factor in determining the stage of cancer. Metastasis is typically denoted as M0 (no distant metastasis) or M1 (presence of distant metastasis).

Grade: It refers to how abnormal the cancer cells appear under a microscope and how quickly the cancer is likely to spread. Tumors are often graded on a scale from 1 to 4, with lower grades indicating slower-growing, less aggressive cancers and higher grades indicating faster-growing, more aggressive cancers.

Biomarkers: In some cases, specific biomarkers or genetic mutations may be associated with certain types of cancer and can provide additional information for staging and treatment decisions.

Once these factors are assessed, doctors use a staging system to categorize cancer into different stages. The most commonly used staging system for solid tumours is the TNM system, which combines information about the size and extent of the primary tumour (T), the involvement of nearby lymph nodes (N), and the absence or presence of distant metastasis (M).

Staging systems may vary depending on the type of cancer, and some cancers have their unique staging systems. Staging is typically determined through a combination of physical examination, imaging tests (such as CT scans, MRIs, or PET scans), biopsy results, and other diagnostic procedures.

Stage 4 Cancer Symptoms

The symptoms of stage 4 cancer can vary depending on the type and location of the cancer, as well as the organs or tissues affected by metastasis. Here are some common symptoms that may occur in stage 4 cancer:

Persistent pain:

Pain can occur in the area of the primary tumour or in areas where cancer has spread (metastasized), such as bones, liver, or lungs. The pain may be dull, aching, or sharp and may worsen over time.

Fatigue:

Feeling extremely tired or lacking energy is a common symptom of advanced cancer. It may not improve with rest and affect your daily activities.

Weight loss:

Unintentional weight loss can occur in stage 4 cancer due to factors such as decreased appetite, changes in metabolism, or cancer-related cachexia (muscle wasting).

Loss of appetite:

Changes in appetite, including a decreased desire to eat or feeling full after eating small amounts, can occur in advanced cancer.

Difficulty swallowing:

Depending on the location of the cancer, difficulty swallowing (dysphagia) may occur, leading to pain or discomfort while eating or drinking.

Swelling or lumps:

Swelling (oedema) in the affected area or the development of lumps or masses may occur due to the growth of the primary tumour or metastatic tumours.

Shortness of breath:

Cancer that has spread to the lungs or other areas near the airways can cause shortness of breath or difficulty breathing.

Changes in bowel or bladder habits:

Symptoms such as constipation, diarrhoea, blood in the stool, or changes in urinary frequency or urgency may occur if cancer affects the gastrointestinal or genitourinary tract.

Neurological symptoms:

Depending on the location of metastasis, stage 4 cancer may cause neurological symptoms such as headaches, weakness, numbness, or changes in coordination.

Jaundice:

Yellowing of the skin and eyes (jaundice) may occur if cancer affects the liver or bile ducts, leading to symptoms such as dark urine, pale stools, and itching.

Cognitive changes:

Metastasis in the brain may cause symptoms such as headaches, seizures, confusion, memory problems, or personality changes.

If you or someone you know is experiencing symptoms that may indicate stage 4 cancer, it’s important to consult a healthcare provider for evaluation and appropriate management. Early detection and treatment can help improve outcomes and quality of life for individuals with advanced cancer.

How is Stage 4 Cancer Typically Treated?

The treatment of stage 4 cancer varies depending on the type of cancer, its location, the extent of spread, and the overall health and preferences of the patient. Generally, the goals of treatment for stage 4 cancer are to manage symptoms, slow the progression of the disease, improve quality of life, and possibly prolong survival. Treatment options may include:

Chemotherapy:

Chemotherapy involves the use of drugs to kill cancer cells or stop them from growing. It is often used in stage 4 cancer to shrink tumours, relieve symptoms, and slow the spread of the disease. Chemotherapy can be administered orally, intravenously, or directly into the affected area, depending on the type of cancer.

Radiation therapy:

High-energy rays or particles are used to prevent cancer cells in this therapy. It may be used to shrink tumours, relieve pain, or control symptoms of stage 4 cancer. Radiation therapy can be targeted at specific areas of the body where the cancer has spread, such as bones or the brain.

Targeted therapy:

Targeted therapy drugs are designed to target specific abnormalities in cancer cells that allow them to grow and spread. These drugs may be used in stage 4 cancer to block the action of specific molecules involved in cancer growth, such as proteins or enzymes. Targeted therapy can be particularly effective in certain types of cancer, such as breast cancer, lung cancer, and melanoma.

Immunotherapy:

In this system body’s immune system identifies and attacks cancer cells. It may be used in stage 4 cancer to boost the immune response against the cancer and help control the disease. Immunotherapy drugs, such as checkpoint inhibitors and CAR-T cell therapy, are being increasingly used in the treatment of advanced cancers.

Surgery:

In some cases of stage 4 cancer, surgery may be used to remove the primary tumour or relieve symptoms caused by cancer, such as blockages or bleeding. Surgery may also be used to remove metastatic tumours in certain situations, such as isolated metastases in the liver or lungs.

Palliative care:

Palliative care focuses on relieving symptoms and improving the quality of life for patients with advanced cancer. It may include treatments such as pain management, medication for nausea and vomiting, nutritional support, and emotional support for patients and their families.

Treatment decisions for stage 4 cancer are often made on a case-by-case basis, taking into account the individual characteristics of the cancer and the patient’s overall health and preferences. Patients need to discuss their treatment options with their healthcare team to develop a personalized treatment plan that aligns with their goals and values.

Average Survival Rate for Stage 4 Cancer

The average survival rate for people with stage 4 cancer varies widely depending on several factors, including the type of cancer, its location, the extent of spread, the overall health of the patient, and the effectiveness of treatment

Five-Year Survival Rates for Distant (Stage 4) Cancer
Cancer Type       Relative 5-Year Survival Rate

  • Leukaemia  65.7%
  • Non-Hodgkin lymphoma 63.9%
  • Thyroid 53.3%
  • Prostate 32.3%
  • Melanoma (skin) 31.9%
  • Breast (female) 30.0%
  • Uterine (endometrial) 18.4%
  • Kidney, renal pelvic 15.3%
  • Colon and rectal 15.1%
  • Bladder 7.7%
  • Lung and bronchus 7.0%
  • Pancreatic 3.1%

For some types of cancer, such as certain metastatic breast cancers and testicular cancers, advancements in treatment options have led to longer survival times, with some patients living for many years with stage 4 disease. However, for other types of cancer, such as pancreatic cancer and certain types of lung cancer, the prognosis for stage 4 disease remains poor, with shorter survival times.

Conclusion

The prognosis for stage 4 cancer varies greatly depending on factors such as the type and location of the cancer, the overall health of the patient, and the response to treatment. It is generally considered more challenging to treat than earlier stages of cancer, but advances in medical technology and treatment options have improved outcomes for some patients with stage 4 cancer.

It plays a pivotal role in guiding treatment decisions, optimizing patient care, and advancing the field of oncology. By identifying treatments with proven efficacy, healthcare providers can tailor therapy to individual patients, maximize treatment benefits, and ultimately improve outcomes for those affected by cancer.

Role of Cancer Medicines

Cancer medicines play a critical role in the management of cancer, contributing to improved outcomes, prolonged survival, and enhanced quality of life for patients. cancer medicines play a multifaceted role in the prevention, diagnosis, treatment, and supportive care of cancer patients. They work through various mechanisms to target and destroy cancer cells or inhibit their growth. The choice of treatment depends on factors such as the type and stage of cancer, and the overall health of the patient. The ultimate goal of cancer medicine is to eradicate cancer cells while minimizing harm to normal tissues, thereby improving patient outcomes and quality of life.

Their continued advancement and integration into comprehensive cancer care strategies hold the promise of further improving outcomes and transforming the landscape of cancer treatment.
Here are some categories of cancer medicines that have shown significant effectiveness in treating certain types of cancer:

Immunotherapy

Immune checkpoint inhibitors, such as pembrolizumab, nivolumab, and atezolizumab, have demonstrated remarkable efficacy in treating a range of cancers, including melanoma, lung cancer, bladder cancer, and renal cell carcinoma. These drugs work by blocking inhibitory signals in the immune system, thereby enabling the body’s immune cells to recognize and destroy cancer cells.

Targeted Therapies

Targeted therapies are designed to specifically target genetic mutations or abnormal proteins that drive cancer growth. Examples include:

Tyrosine Kinase Inhibitors (TKIs)

Drugs like imatinib, erlotinib, and crizotinib target specific tyrosine kinases that are overactive in certain cancers, such as chronic myeloid leukemia, non-small cell lung cancer, and ALK-positive lung cancer, respectively.

HER2-Targeted Therapies

Drugs like trastuzumab, pertuzumab, and ado-trastuzumab emtansine (T-DM1) target the HER2 protein overexpressed in HER2-positive breast cancer and HER2-positive gastric cancer.

PARP Inhibitors

Olaparib, rucaparib, and niraparib are PARP inhibitors used in the treatment of ovarian cancer and certain other cancers with BRCA mutations.

Chemotherapy

While often associated with significant side effects, chemotherapy remains a cornerstone of cancer treatment, particularly for aggressive or advanced cancers. Common chemotherapy drugs include cisplatin, paclitaxel, doxorubicin, and fluorouracil, used in various combinations and regimens depending on the type of cancer being treated.

Hormonal Therapies

Hormonal therapies are effective in treating hormone-sensitive cancers, such as breast cancer and prostate cancer. Drugs like tamoxifen, aromatase inhibitors (e.g., anastrozole, letrozole), and androgen receptor antagonists (e.g., enzalutamide, abiraterone) are commonly used to block hormone receptors or inhibit hormone production.

Radiation Therapy

Radiation therapy uses high-energy radiation beams to target and kill cancer cells. It can be used as a primary treatment or in combination with surgery, chemotherapy, or immunotherapy. Radiation therapy is effective in treating localized cancers, including breast cancer, prostate cancer, and various types of head and neck cancers.

CAR T-cell Therapy

CAR T-cell therapy, although relatively new, has shown promising results in treating certain types of leukemia and lymphoma. Chimeric antigen receptor (CAR) T-cell therapy involves genetically modifying a patient’s T cells to recognize and attack cancer cells expressing specific antigens, such as CD19 in B-cell malignancies.

Conclusion

It’s important to note that the effectiveness of anti-cancer drugs can vary greatly depending on individual factors, and treatment decisions should be made in consultation with oncologists and other healthcare providers based on the latest clinical evidence and guidelines. Additionally, ongoing research and clinical trials continue to explore new therapeutic approaches and combinations to further improve outcomes for cancer patients.

What If Your Cancer Treatment Is Unaffordable

What To Do If Your Cancer Treatment Is Too High

If you have cancer, like many others, you may be worried about how you will pay for your care and prescription drugs. Cancer treatment is costly and managing health insurance can be challenging sometimes.

People who are diagnosed with cancer frequently worry about the cost of their care. Even with the assistance of health insurance, cancer treatment can be costly.

You can ease some of your financial distress by consulting a reliable specialist and asking for assistance. When you get in touch with your medical team, an oncology social worker, or a non-profit organization, you might be surprised by the array of services that become available.

Cancer Treatment Cost

It’s essential to know the factors that determine the overall cost of cancer treatment.

The screening and diagnostic tests, as well as your initial appointment with your primary care physician, are only the beginning. You will consult with doctors and come up with a treatment plan once the cancer has been proven.

Cancer Treatment options include simple outpatient operations, radiotherapy, chemotherapy, and surgery. Prescriptions, specialists, and costs for labs, facilities, and equipment are all added to the bill. The next step is a follow-up, which can go on for a lifetime and is spaced out over months and years.

Then there are the alleged “other costs.” They are extremely real even though they don’t always appear on a bill:

The price of basic transportation to and from your appointments with providers and therapies

Expenses for overnight travel, accommodation, and meals if your therapy is not nearby

Lost pay for time away from work, which can include sick days, temporary disability, or permanent unemployment

Customized shopping lists to support you in keeping a nutritious diet

Financial concerns over the cost of treatment are a major source of stress for many families dealing with cancer, and they often don’t know where to turn. It might be challenging to ask for and accept support.

Managing the expense of cancer care requires asking two key issues:

  • How much money will I have to spend on my cancer diagnosis and treatment?
  • Can I currently arrange the financial part of my cancer treatment?

Asking for assistance is the first step towards controlling the expense of cancer treatment.

Can a friend or member of your family assist you? If not, request a referral from your physician to a financial counsellor, oncology social worker, or non-profit group to assist you in handling financial concerns and cancer expenses. Many people who receive a cancer diagnosis rely on someone else for assistance in covering the costs of their treatment. These problems must be addressed by someone.
