Unusual Bleeding or Discharge: Any unexpected bleeding or discharge from any part of the body.
Thickening or Lump in the Breast or Elsewhere.
Indigestion or Trouble Swallowing: Persistent digestive issues or difficulty swallowing.
Recent Change in a Wart or Mole or Any New Skin Change.
Nagging Cough or Hoarseness: A persistent cough that doesn't go away.
Important Note: These symptoms can also be caused by less serious conditions. However, it's crucial to get them checked by a healthcare professional in Bengaluru or your locality to rule out cancer or diagnose it early.
Empowering Yourself Through Prevention: Steps You Can Take
While not all cancers are preventable, adopting a healthy lifestyle can significantly reduce your risk:
Say No to Tobacco: Tobacco use (smoking and smokeless forms) is a major risk factor for several cancers, especially oral, lung, and throat cancer, highly prevalent in India. Quitting is one of the best things you can do for your health.
Maintain a Healthy Diet: Focus on a diet rich in fruits, vegetables, whole grains, and lean protein. Limit processed foods, red meat, and sugary drinks. Be mindful of traditional Indian diets and opt for healthier cooking methods and ingredient choices.
Stay Physically Active: Regular exercise helps maintain a healthy weight and reduces the risk of several cancers. Aim for at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic activity per week.
Get Vaccinated: Vaccines are available to protect against certain cancer-causing viruses, such as the Hepatitis B virus (which can lead to liver cancer) and the Human Papillomavirus (HPV) (which is linked to cervical and other cancers). Consult your doctor in Bengaluru about recommended vaccinations.
Limit Alcohol Consumption: Excessive alcohol intake increases the risk of several cancers, including breast, liver, and colorectal cancer.
Protect Yourself from Excessive Sun Exposure: Limit time in the sun, especially during peak hours, and use sunscreen to reduce the risk of skin cancer.
Be Aware of Environmental Factors: Minimise exposure to known carcinogens and air pollution, which is a significant concern in many Indian cities.
Regular Screenings: Participate in recommended cancer screening programs, such as mammograms for breast cancer, Pap smears and HPV tests for cervical cancer, and colorectal cancer screenings based on age and risk factors. Early detection through screening saves lives.
Your Top 20+ Questions About Cancer Answered
Here are answers to some of the most common and important questions about cancer in India.
1) What exactly is cancer?
Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. These cells can invade and destroy healthy body tissues.
2) How does cancer develop?
Cancer develops due to changes (mutations) in a cell's DNA. These mutations can be inherited, occur due to environmental factors (like radiation or chemicals), or happen randomly as cells divide.
3) Are all tumours cancerous?
No. Tumours can be benign (non-cancerous) or malignant (cancerous). Benign tumours do not spread to other parts of the body and are usually not life-threatening. Malignant tumours can invade nearby tissues and spread (metastasize) to distant sites.
4) What are the most common types of cancer in India?
In women: Breast, cervical, oral, colorectal, and lung cancer. In men: Oral, lung, prostate, colorectal, and stomach cancer.
5) Is cancer always fatal?
No. Many types of cancer are highly treatable, especially when detected early. Survival rates vary greatly depending on the type and stage of cancer, as well as the treatment received.
6) How is cancer diagnosed?
Diagnosis often involves a combination of physical exams, imaging tests (like X-rays, CT scans, MRI), laboratory tests (blood tests, tumour markers), and biopsies (removing a tissue sample for examination under a microscope). Diagnostic facilities are increasingly available in cities like Bengaluru.
7) What are the main types of cancer treatment?
Common treatments include surgery, chemotherapy, radiation therapy, targeted therapy, immunotherapy, and hormone therapy. The best approach often involves a combination of these.
8) What is chemotherapy?
Chemotherapy uses drugs to kill cancer cells or slow their growth. It's often given orally or intravenously.
9) What is radiation therapy?
Radiation therapy uses high-energy rays (like X-rays or protons) to kill cancer cells in a specific area of the body.
10) What is targeted therapy?
Targeted therapy uses drugs that specifically target certain molecules (like proteins) involved in cancer cell growth and survival. It often has fewer side effects than chemotherapy.
11) What is immunotherapy?
Immunotherapy helps your body's own immune system fight cancer. It can boost the immune response or make cancer cells more recognizable to the immune system.
12) Can stress cause cancer?
While chronic stress isn't considered a direct cause of cancer, it can weaken the immune system and influence unhealthy behaviours (like smoking or poor diet) that are known risk factors.
13) Are there any hereditary cancers?
Yes, certain cancers have a strong genetic link. If you have a family history of specific cancers (like breast, ovarian, or colorectal cancer), genetic testing may be recommended to assess your risk.
14) What role does diet play in cancer prevention?
A diet rich in antioxidants, fiber, and phytochemicals (found in fruits, vegetables, and whole grains) can help protect cells from damage that can lead to cancer. Limiting processed foods and red meat is also advisable.
15) Is air pollution linked to cancer?
Yes, exposure to air pollution, especially particulate matter, is a known risk factor for lung cancer and potentially other cancers. This is a significant concern in many urban areas in India.
16) What is palliative care for cancer patients?
Palliative care focuses on providing relief from the symptoms and stress of cancer, improving the quality of life for both the patient and their family. It's not the same as end-of-life care and can be started at any stage of the illness.
17) Where can I find reliable cancer information and support in Bengaluru?
Bengaluru has several reputable cancer hospitals and support groups. Consult your doctor for referrals or search online for "cancer support groups Bengaluru" or "best cancer hospitals Bangalore."
18) How can I support someone who has cancer?
Offer practical help (like running errands or providing meals), listen without judgment, and be a source of emotional support. Respect their needs and wishes.
19) Are there any alternative therapies that can cure cancer?
While complementary therapies can help manage symptoms and improve well-being, there is no scientific evidence that alternative therapies alone can cure cancer. It's crucial to rely on evidence-based medical treatments.
20) What is the importance of early detection in cancer?
Early detection often means that the cancer is smaller, hasn't spread, and is more likely to be treated successfully. Screening programs play a vital role in detecting cancers at an early stage.
21) What advancements have been made in cancer treatment in recent years?
Significant advancements include targeted therapies, immunotherapy, minimally invasive surgical techniques, and more precise radiation therapy, leading to improved survival rates and quality of life for many patients.
22) How can I reduce my risk of oral cancer in India?
The most effective way is to avoid all forms of tobacco (smoking, chewing gutka, paan masala) and limit alcohol consumption. Regular dental checkups can also help detect early signs.
Hope and Progress in the Fight Against Cancer
While cancer remains a serious health challenge in India, advancements in research, treatment, and awareness are offering increasing hope. By understanding the risks, recognizing early signs, embracing preventive measures, and supporting those affected, we can collectively work towards a future with better cancer outcomes.
If you have any concerns about cancer, please don't hesitate to consult with a healthcare professional in Bengaluru or your local area. Early action can make all the difference.
