The Most Significant Benefits of Proton Therapy1-11

Proton therapy is more precise than standard radiation and conforms to the shape of the tumor. The benefits of which include:

  • Fewer short- and long-term side effects4-9
  • Proven efficacy in adults and children4-6
  • Precise targeting of tumors and cancer cells, which reduces the risk of damage to surrounding healthy tissue and organs1-3
  • Reduced likelihood of secondary tumors caused by treatment5-6
  • Treatment for recurrent tumors, even in patients who have already received radiation5-6
  • Improved quality of life during and after treatment8

Additionally, proton therapy may be appropriate for patients who have reached the limit of traditional radiation and for pediatric patients, who can benefit in particular from a reduced risk of long-term side effects.

How Does Proton Therapy Compare to Standard Radiation?

Proton therapy and standard X-ray therapy both kill cancer cells by preventing them from dividing and growing. The biggest difference is that proton therapy delivers less radiation to healthy tissue because protons can be precisely controlled.

In standard radiation therapy treatments, energy is released continuously as X-rays move through the body. This means healthy tissue along their path, in front of and behind the tumor, can receive unintended damage. Depending on the location of the tumor, vital organs such as the brain, heart or spine can be affected.

In proton therapy treatments, less energy is released as the protons enter the body and all of the remaining energy is deposited at the treatment site, reducing the amount of healthy tissue that receives dose.12

Study Compares Effects of X-ray Radiation with Proton Therapy

A study analyzed patients treated with X-ray radiation and compared them with patients treated with proton therapy. Of the patients treated with X-ray radiation, 12.8 percent developed secondary cancers caused by treatment, while only 6.4 percent of the proton therapy patients developed secondary cancers.6
