What does radiation therapy primarily treat?

Radiation therapy primarily treats cancer by using targeted doses of radiation to destroy or damage cancer cells. This treatment works by interfering with the ability of cancer cells to grow and divide. By using high-energy particles or waves, such as X-rays, gamma rays, or electron beams, medical professionals can target tumors specifically, minimizing damage to the surrounding healthy tissue.

Although radiation therapy can sometimes be used in a palliative manner to relieve symptoms in other conditions, its primary and most effective application is in oncology. This makes the use of radioactive substances a fundamental aspect of cancer treatment, distinguishing it from other medical conditions such as brain injuries, cardiovascular diseases, or digestive disorders, which require different treatment modalities.
