Comparing Cancer Treatments: CyberKnife vs. Proton Therapy

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

CyberKnife is an advanced technology that performs stereotactic body radiation therapy. During treatment, high doses of radiation are delivered to tumors with sub-millimeter precision, minimizing radiation exposure to nearby healthy tissue. Proton therapy has the ability to minimize 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:
