Unmatched Precision

Proton beams can be manipulated to conform to the unique size and shape of the tumor and stop at its edge precisely.

Radiation Dose Variation

Doctors can vary the intensity of the radiation dose at any point within the tumor to optimize treatment.

Treatment for More Tumor Types

Patients with tumors that are larger, more irregularly shaped or found near critical organs or structures can be treated.

Lower Incidence of Secondary Tumors

Reduced radiation to healthy tissues lowers the risk of secondary cancer.

Reduced Side Effects

Diarrhea, nausea, headache and loss of appetite are less likely.

Faster Treatment Times

Our treatment plans can be loaded into the computer and completed in a matter of minutes.
