Overview

The prostate cancer rate has risen steadily, with advanced-stage diagnoses increasing by 5 % per year. Next to skin cancer, prostate cancer is the most common malignancy in American men.

One in 41 men will die of prostate cancer, though most diagnosed do not. Because it often grows slowly, many patients choose active surveillance. Radiation therapy remains a cornerstone treatment based on stage and individual factors.

Proton Therapy for Prostate Cancers

Why proton therapy?

Proton beams stop precisely at the tumor, unlike X-rays that pass through normal tissues before and after the target. This allows higher tumor doses with less collateral damage, reducing side effects.

Radiation is a potential prostate cancer treatment:

  • If the cancer is confined to the prostate gland and low grade
  • For tumors that have extended outside the prostate into nearby tissues
  • If cancer persists or recurs after surgery
  • To control advanced disease or palliate symptoms

Prostate cancer by the numbers

The American Cancer Society estimates over 288,000 new prostate cancer cases this year in the U.S., and nearly 35,000 deaths.
