Chemotherapy is a medical treatment that uses powerful drugs to kill cancer cells or prevent them from multiplying. The drugs are usually given orally or intravenously and can be used alone or in combination with other treatments such as surgery or radiation therapy.
Chemotherapy works by targeting rapidly dividing cancer cells, which are more vulnerable to damage from the drugs than normal, healthy cells. The drugs can be used to treat many types of cancer, including leukemia, lymphoma, breast cancer, lung cancer, and many others.
Chemotherapy is often given in cycles, with treatment periods followed by rest periods to allow the body to recover. The duration and frequency of chemotherapy depends on factors such as the type and stage of cancer being treated, the overall health of the patient, and the specific drugs being used.
Like any medical treatment, chemotherapy can have side effects. These can include fatigue, hair loss, nausea, vomiting, and damage to healthy tissues such as the lining of the mouth and digestive tract. However, modern chemotherapy drugs have greatly reduced the risk of side effects, and many people are able to continue their normal activities during treatment.
Chemotherapy is a critical component of cancer treatment and can be an effective way to shrink or eliminate cancerous tumors. The decision to undergo chemotherapy should be made in consultation with a medical professional and based on individual factors such as the type and stage of cancer, overall health, and personal preference
