Treatment Comparison: Proton Therapy vs. CyberKnife

Patients seeking an advanced treatment option for their prostate cancer may compare CyberKnife® and proton therapy. While both are known for their precision and minimal side effects, each targets the tumor differently.

CyberKnife technology performs stereotactic body radiation therapy. During treatment, high doses of radiation are delivered to the prostate with sub-millimeter precision, minimizing damage to nearby healthy tissue. Proton therapy has the capability of minimizing damage to healthy tissue through the use of particle therapy. During proton therapy, doctors determine the precise point in a patient’s body where the proton releases the majority of energy, maximizing exposure to the treatment area.

The table below demonstrates additional ways the treatment types differ:

CyberKnife and proton therapy are two of the many treatment options to consider and the right treatment for you can depend on the location, size and stage of your tumor. Talk with your physician to determine the option that best suits your needs.
