Comprehensive Guide to Radiation Therapy – Types, Side Effects, and Survival Rates in Cancer Treatment

Types of Radiation Used in Cancer Treatment

Radiation therapy, also known as radiotherapy, is a common treatment method for various types of cancer. It uses high-energy radiation to target and kill cancer cells. There are different types of radiation used in cancer treatment, each suitable for specific situations and conditions. Some of the main types include:

  1. External Beam Radiation: This type of radiation therapy is delivered from outside the body using a machine that aims high-energy rays at the cancerous cells. It is a non-invasive and painless procedure commonly used for treating solid tumors.
  2. Brachytherapy: Also known as internal radiation therapy, brachytherapy involves placing radioactive material directly into or near the tumor site. This allows for a higher dose of radiation to be delivered to the cancer cells while minimizing exposure to surrounding healthy tissues.
  3. Proton Therapy: Proton therapy is a type of external beam radiation that uses protons to target tumors. Protons are positively charged particles that can precisely deliver radiation to the tumor site, reducing damage to nearby tissues. This method is particularly effective for tumors located near sensitive organs.
  4. Stereotactic Radiosurgery: Despite its name, radiosurgery does not involve actual surgery. It is a specialized form of radiation therapy that delivers high doses of radiation to small, well-defined tumors or lesions in a single session.
  5. Gamma Knife Radiosurgery: This technique is especially useful for treating brain tumors and abnormalities. It uses multiple beams of gamma radiation to target the tumor from different angles, resulting in a highly precise and effective treatment.

Each type of radiation therapy has its advantages and is chosen based on the specific characteristics of the cancer, its location, and the overall health of the patient. It is important for patients to discuss the benefits and risks of each treatment option with their healthcare provider to determine the most suitable approach for their condition.
