Proton beam therapy

What it is

Proton beam therapy is a type of radiation therapy that uses protons instead of X-rays to kill cancer cells. It works by delivering a precise dose of radiation directly to the tumor, minimizing damage to surrounding healthy tissues.

What research shows

Studies suggest that proton beam therapy is effective in treating various types of cancer, including brain tumors, prostate cancer, and esophageal cancer. Evidence indicates that proton beam therapy can improve local control and reduce side effects compared to traditional radiation therapy. However, more research is needed to fully understand its benefits and limitations.

Current status

Proton beam therapy is a viable treatment option for certain types of cancer, particularly those that are difficult to treat with traditional radiation therapy. However, its use is still limited by its high cost and availability, and more research is needed to determine its optimal role in cancer treatment.
