About Proton Therapy

Proton therapy is an advanced form of radiation therapy that uses a single beam of high-energy protons to treat various forms of cancer. Just as with conventional radiation therapy, protons treat tumors by directing radiation into the tumor site where doses of radiation destroy cancerous cells.

However, unlike conventional radiation therapy, in which x-ray beams deposit their energy into the healthy tissue prior to entry and upon exit of the tumor site, the timing and dosage of protons’ energy can be controlled, allowing the maximum energy to be deposited directly into the tumor and reducing damage to nearby healthy tissue. This limits negative side effects such as skin burns, fatigue and impact to bodily functions that are a routine part of conventional radiation treatment.

How it Works

When doses of protons (positively charged parts of an atom) enter a tumor, they deposit most of their energy at a specific target, destroying cancerous cells and preserving surrounding healthy tissue. This differs from conventional radiation therapy because a less significant dose of protons enter the body, therefore reducing damage to surrounding healthy tissue and critical organs. The result is a smaller chance for side effects and secondary cancers.

Our treatment rooms use pencil beam and uniform scanning, which further increases the precision of radiation, reducing overall treatment time and allowing the tumor to be directly targeted with aggressive doses of radiation.

How do I know if it’s for me?

A non-invasive treatment, proton therapy for cancer is best used to treat individuals with a localized tumor, in which the cancer has not spread to other parts of the body and in situations in which tumors cannot be removed surgically or, in some cases, require radiation therapy following surgery. Proton therapy may be combined with other treatment options, depending on the specific details of your case.
