How Proton Therapy Works

How Proton Therapy Works


Proton therapy uses a precision-focused radiation beam to target and treat both benign and malignant tumors. Unnecessary radiation delivery to uninvolved normal tissues should be avoided whenever possible, and proton beam radiation allows for the maximal sparing of normal tissues. Unlike traditional radiation, which has a more generalized path that sends radiation through the tumor, proton radiation utilizes specific frequencies to help dial in the intended point of treatment. This creates a more targeted radiation that allows physicians the ability to focus higher levels of radiation directly on the tumor. The result spares more healthy cells, tissue and organs from radiation, which can significantly reduce side effects and treatment discomfort.3-4, 6-8, 15

Proton Radiation

Proton therapy treatments are nonsurgical, noninvasive and may result in minimal side effects, though some patients may experience fatigue or minor skin irritation or hair loss within the treated area. More serious complications are possible, though rare, and are dependent on factors such as treatment plan, tumor location and size.

Typically, proton therapy patients receive daily treatment for a number of weeks depending on variables such as tumor type, size and location. Most patients continue to enjoy daily activities outside of therapy sessions.3-4, 6-8, 15
