Chemotherapy is one of the most widely recognized treatments for cancer, playing a crucial role in the fight against this disease. It involves the use of powerful drugs to destroy rapidly growing cancer cells in the body. Dr. Rajib Bhattacharjee, a leading oncologist in Kolkata, provides comprehensive insights into how chemotherapy works, its side effects, and what patients can expect during the treatment process.
What is Chemotherapy?
Chemotherapy, often simply referred to as “chemo,” is a type of cancer treatment that uses one or more anti-cancer drugs to target and kill cancer cells. Unlike surgery or radiation, which are localized treatments, chemotherapy can work throughout the entire body, making it particularly effective for cancers that have spread to other areas.
How Does Chemotherapy Work?
Chemotherapy works by targeting cells that divide and grow rapidly, a characteristic of cancer cells. The drugs used in chemotherapy disrupt the cell cycle, preventing cancer cells from multiplying and causing them to die. However, because chemotherapy affects all rapidly dividing cells, it can also impact healthy cells, leading to side effects.
When is Chemotherapy Used?
Dr. Rajib Bhattacharjee explains that chemotherapy can be used in various stages of cancer treatment:
- Adjuvant Chemotherapy: Administered after surgery to eliminate any remaining cancer cells and reduce the risk of recurrence.
- Neoadjuvant Chemotherapy: Given before surgery to shrink tumors, making them easier to remove.
- Palliative Chemotherapy: Used in advanced stages of cancer to relieve symptoms and improve quality of life.
- Combination Therapy: Often combined with other treatments like surgery, radiation, or targeted therapy to enhance the effectiveness of treatment.
Common Side Effects of Chemotherapy
While chemotherapy is effective in treating cancer, it also comes with a range of side effects due to its impact on healthy cells. Common side effects include:
- Fatigue: One of the most common side effects, causing persistent tiredness.
- Nausea and Vomiting: Chemotherapy can trigger nausea and vomiting, which are often managed with medication.
- Hair Loss: Many chemotherapy drugs cause hair loss, which is usually temporary.
- Infection Risk: Chemotherapy can weaken the immune system, making patients more susceptible to infections.
- Mouth Sores: Ulcers and sores in the mouth can occur due to the damage to the lining of the digestive tract.
- Anemia: A decrease in red blood cells can lead to anemia, causing fatigue and weakness.
Managing Side Effects
Dr. Rajib Bhattacharjee emphasizes that while the side effects of chemotherapy can be challenging, they are often manageable. Patients are provided with supportive care, including medications to reduce nausea, and strategies to manage fatigue and other symptoms. Regular monitoring and adjustments to the treatment plan can help minimize discomfort and maintain quality of life during treatment.
Conclusion
Chemotherapy remains a cornerstone of cancer treatment, offering hope to millions of patients worldwide. While the journey through chemotherapy can be difficult, it is an essential tool in the fight against cancer. Dr. Rajib Bhattacharjee, one of Kolkata’s best oncologists, is dedicated to providing expert care and guidance to patients undergoing chemotherapy, ensuring they receive the best possible treatment tailored to their needs.
