Treatment Comparison: CyberKnife versus Proton Therapy

When seeking advanced treatment options for prostate cancer, patients may find themselves comparing 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 tumors 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 guide below demonstrates additional ways the treatment types differ.
