Find out about the latest breast cancer research on external beam therapy, called “proton beam therapy.” Dr. Forouzannia explains that this therapy is still considered experimental.
Afshin Forouzannia, MD: Proton Beam Therapy is a form of external beam therapy, but instead of using photon rays like standard external beam does, they use proton, which is essentially a heavy particle. The advantage of proton is that it gives or deposits its energy at a particular depth and then the dose falls off rapidly afterwards.
There are a lot of theoretical advantages to this potentially reducing toxicity, but at this point, it’s still considered experimental because there are only few proton centers around in the country and they haven’t been able to demonstrate any particular advantage compared to photon therapy, although there’s a lot of ongoing studies and we need to just learn more about this technology and how it can be used in the clinic.
