Radiotherapy Vs Chemotherapy

Radiotherapy, also known as radiation therapy, is a medical treatment that uses high doses of radiation to kill or damage cancer cells. It works by targeting the DNA of the cancer cells, preventing them from growing and dividing. Radiotherapy can be delivered externally, using a machine to direct radiation beams at the tumor, or internally, through the placement of radioactive materials near the cancerous tissue. It is often used as a primary treatment, as well as in conjunction with surgery or chemotherapy, to shrink tumors or eliminate remaining cancer cells after surgery.

Chemotherapy is a systemic treatment that utilizes drugs to kill or inhibit the growth of cancer cells throughout the body. It works by targeting rapidly dividing cells, a characteristic of many cancer cells, but can also affect normal cells that divide quickly, leading to potential side effects. Chemotherapy can be administered orally or intravenously and is often used in combination with other treatments, such as surgery and radiation therapy, to improve outcomes. The specific regimen of chemotherapy drugs and their dosages depend on the type of cancer being treated, as well as the individual patient's health.
