Targeted, high-energy radiation is used to destroy cancer cells while minimizing damage to surrounding healthy tissue.
Radiation therapy, or radiotherapy, is a type of cancer treatment that uses high-energy radiation to kill or control the growth of cancer cells. It's a widely used treatment, with about half of cancer patients needing it at some point. The radiation damages the DNA of cancer cells, ultimately leading to their death or preventing them from dividing.
Types of
Radiation Therapy:
The most common type, where radiation beams are aimed at the
tumor from a machine outside the body.
Radioactive material is placed directly into or near the
tumor, either temporarily or permanently.
Uses radioactive substances, like radiolabeled antibodies, that travel through the bloodstream to reach cancer cells throughout the body.
