Cancer develops due to changes (mutations) in a cell's DNA. These mutations can be inherited from your parents or acquired during your lifetime due to various factors. Common risk factors include exposure to certain chemicals (like those in tobacco smoke), radiation, some viruses (like HPV), obesity, alcohol consumption, and aging. Often, cancer results from a combination of these factors.

Yes, many cancers are curable, especially when detected at an early stage. With the latest advancements in treatment, even some advanced-stage cancers can now be cured. Early diagnosis significantly improves the chances of a successful outcome.

Absolutely NOT. Cancer is a non-communicable disease, meaning it cannot be passed from person to person. You cannot get cancer by touching, being near, or using items previously used by someone with cancer. It's safe to interact with and support cancer patients without fear of transmission.

Yes, some cancers can have a hereditary link, but not all. While most cancers occur sporadically due to random genetic mutations or environmental factors, certain types, like breast cancer and colon cancer, have a hereditary component in over 50% of cases. Other factors contributing to cancer include viral infections, lifestyle choices, and environmental changes.

Yes, certain cancers are preventable. We have a good understanding of the causes for some cancers, allowing for preventive measures. For instance, cervical cancer, primarily caused by chronic HPV infections, can be effectively prevented through HPV vaccination administered at the appropriate age.

Cancer treatment is highly personalized and depends on several factors, including the patient's overall health, the specific type and stage of the tumour, and its molecular biology. Common treatment options include:

• Surgery: To physically remove the cancerous tissue.

• Radiation Therapy: Uses high-energy rays to destroy cancer cells.

• Chemotherapy: Uses powerful drugs to kill cancer cells throughout the body.

• Immunotherapy: Boosts the body's own immune system to fight cancer.

• Targeted Therapy: Drugs that specifically attack certain vulnerabilities in cancer cells.

• Radionuclide Therapy: Uses radioactive substances to target and destroy cancer cells.

• Hormonal Therapy: Blocks or removes hormones that fuel certain cancer types.

• Bone Marrow Transplant: Replaces damaged bone marrow with healthy stem cells.

In India, breast cancer is the most common cancer overall and particularly among females. Following breast cancer, common cancers in India include cervical cancer, oral cavity cancer, and lung cancer. (For more detailed global statistics, you can refer to resources like Globocan 2020).

Regular cancer screening is incredibly helpful because it allows us to detect cancer at its earliest stages. Cancers found early are typically completely curable, significantly improving treatment outcomes and survival rates.

Blood cancer occurs in both children and adults. While it affects both age groups, it tends to be more common in children compared to many other types of cancer.

Metastatic cancer occurs when cancer cells from an original tumour spread through the blood or lymphatic system to other organs in the body and begin to grow there. While it is a more challenging stage of cancer, metastatic disease is often treatable, and management depends on the patient's condition and the specific cancer's biology.

Cancer has become increasingly noticeable as it is now the second most common cause of death globally, following ischemic heart disease (IHD). It accounts for approximately 23% of total deaths. This rise is partly due to increased lifespan, better diagnostic tools, and changes in lifestyle and environmental factors.

Cancer in children is mainly attributed to genetic factors. Additionally, exposure to certain carcinogens in the mother's environment or diet during pregnancy can also play a role, though this is less common.

Common symptoms of cancer often include long-standing specific symptoms that do not resolve with medication, unexplained weight loss, and persistent fatigue. The specific symptoms can vary greatly depending on the organ involved. For example, a non-healing ulcer in the oral cavity could be a symptom of oral cancer.

No, there is no single universal test to detect all cancers. Cancer is not one disease; it involves abnormal cell growth that can occur in any organ with living cells. Because each organ and cancer type is different, diagnostic tests vary accordingly. For example, a Pap smear test is specifically used for screening cervical cancer.

Cancer diagnosis typically involves a combination of methods:

• Physical Exam: A doctor checks for lumps or unusual changes.

• Imaging Tests: X-rays, CT scans, MRIs, PET scans, and ultrasounds help visualize internal organs and detect tumors.

• Biopsy: A small tissue sample is removed and examined under a microscope for cancer cells. This is often the definitive diagnostic test.

Laboratory Tests: Blood, urine, and other fluid tests can identify tumor markers or other indicators of cancer.

Even for cancer in the same organ, treatment options can differ significantly based on several crucial factors:

• Stage of Presentation: How far the cancer has spread.

• Patient-Related Factors: The patient's overall health, age, and co-existing medical conditions.

• Molecular Biology of the Disease: Specific genetic mutations or biomarkers present in the cancer cells, which can indicate responsiveness to certain targeted therapies.

Yes, cancer can affect any organ that contains living cells. This includes virtually all parts of the body. However, cancer will not occur in dead cells, such as those found in hair and nails.

No, not all patients experience hair loss after chemotherapy. Whether hair loss occurs depends entirely on the specific type of chemotherapy drugs used and the individual patient's response. Your doctor or nurse will inform you about potential side effects, including hair loss, associated with your prescribed treatment regimen.

Pain and palliative care focus on improving the quality of life for patients facing a serious illness like cancer, particularly in advanced stages or when curative treatment options are exhausted or not suitable. The goal here is not to cure the cancer itself, but to effectively manage cancer symptoms, especially pain, and provide holistic support for the patient and their family.

Cancer commonly occurs in old age because it is often caused by DNA damage accumulated over time due to carcinogens or errors during cell division. While our body has sophisticated DNA repair mechanisms, these mechanisms can become less efficient as we age. The failure of these repair systems allows damaged cells to proliferate, leading to cancer.

Yes, it is highly recommended that all cancer patients undergo psychological assessment and follow-up before, during, and after treatment. The cancer journey, with its extended treatment periods and follow-up needs, can be emotionally challenging. Psychological counselling helps patients cope with stress, anxiety, depression, and other emotional impacts, significantly improving their overall well-being and quality of life.
