Chemotherapy is a type of cancer treatment that involves the use of drugs to destroy cancer cells. It works by interfering with the growth of cancer cells, either by killing them directly or by stopping them from dividing and multiplying. Chemotherapy can be given orally, through injection, or through intravenous (IV) infusion. It is often used in combination with other treatments, such as surgery or radiation therapy.
Radiation therapy is a type of cancer treatment that uses high-energy particles or waves, such as X-rays, gamma rays, and protons, to kill cancer cells. It works by damaging the DNA of the cancer cells, preventing them from growing and dividing. Radiation therapy can be used to target a specific area of the body, or it can be used to treat the entire body. It is often used in combination with other treatments, such as chemotherapy or surgery.
