Radiation therapy is a common treatment for cancer that uses high-energy radiation, such as X-rays or protons, to kill cancer cells. Radiation therapy works by damaging the DNA of cancer cells, preventing them from dividing and growing.

Radiation therapy can be delivered externally or internally. External radiation therapy is the most common type of radiation therapy and involves using a machine to deliver radiation to the area of the body where the cancer is located. Internal radiation therapy, also called brachytherapy, involves placing a small amount of radioactive material directly into or near the cancer.

Radiation therapy can be used alone or in combination with other treatments such as chemotherapy or surgery. The treatment plan and dosage depend on factors such as the type and stage of cancer, the location of the tumor, and the overall health of the patient.

Radiation therapy can cause side effects, such as fatigue, skin irritation, and digestive problems, and these side effects can vary depending on the location and dosage of the radiation. However, many patients are able to manage these side effects with medication and lifestyle adjustments.

Radiation therapy can be an effective treatment for cancer, but it is not without risks. Long-term side effects, such as damage to healthy tissue surrounding the tumor or the development of a secondary cancer, are possible. However, advances in radiation therapy technology and treatment planning have helped to minimize these risks and improve the effectiveness of radiation therapy.

The decision to use radiation therapy as a treatment for cancer depends on several factors, including the type and stage of cancer, the patient’s overall health, and other medical conditions. It is important for patients to discuss the potential benefits and risks of radiation therapy with their healthcare provider.
