FAQs on Chemotherapy Video Lecture - Science & Technology for UPSC CSE

1. What is chemotherapy?
Chemotherapy is a treatment method that uses drugs to kill cancer cells. It can be given orally or through injections, and it works by targeting rapidly dividing cells in the body, including cancer cells.
2. How does chemotherapy work?
Chemotherapy works by interfering with the ability of cancer cells to divide and grow. The drugs used in chemotherapy either kill the cancer cells directly or prevent them from multiplying. Additionally, chemotherapy can also affect normal cells that divide rapidly, such as those in the bone marrow, hair follicles, and digestive system.
3. What are the side effects of chemotherapy?
Chemotherapy can have various side effects, which can vary depending on the type of drugs used and the individual's response. Common side effects include nausea, vomiting, hair loss, fatigue, decreased appetite, and increased risk of infection. However, advancements in supportive care have helped in managing and reducing these side effects.
4. Is chemotherapy the only treatment option for cancer?
No, chemotherapy is not the only treatment option for cancer. Depending on the type and stage of cancer, other treatment modalities such as surgery, radiation therapy, targeted therapy, immunotherapy, or a combination of these approaches may be recommended. The choice of treatment depends on various factors and is determined by the oncologist.
5. Can chemotherapy cure cancer?
In some cases, chemotherapy can lead to a complete cure of cancer, especially when the cancer is diagnosed at an early stage and is sensitive to chemotherapy drugs. However, the outcome varies for each individual and depends on several factors, including the type of cancer, stage, overall health, and response to treatment. In some cases, chemotherapy may be used to control the growth and spread of cancer or to relieve symptoms and improve quality of life.
