Chemotherapy

Chemotherapy is the use of powerful drugs to kill cancer cells and stop or slow the growth of tumors. It is a vital component of cancer treatment, and has become increasingly important for the survival and improved quality of life of cancer patients. The drugs work by interfering with the growth and division of cancer cells, and can be administered orally, topically, or intravenously. Side effects vary depending on the type and dose but may include fatigue, hair loss, nausea, vomiting, decreased immunity, and organ damage. Chemotherapy can be used alone or in combination with other treatments such as radiotherapy and surgery.
