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.

Radiation Protection

More targeted radiation helps protect the heart, lungs, spinal cord, other breast and healthy breast tissue.

Lower Incidence of Secondary Tumors

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

Reduced Side Effects

Risk of cardiac events, lung cancer and pneumonitis are less likely.
