The Advantages of Proton Therapy

  • Unlike traditional radiotherapy treatment, proton radiation is directed to the tumor with pinpoint accuracy resulting in less damage to surrounding healthy organs and tissue.
  • With proton, doctors have the ability to deliver a higher dose of radiation to the tumor – and the higher the radiation dose, the better the chance of destroying all the cancer.
  • Treatment is non-invasive and painless.
  • Treatment is provided in an outpatient setting – patients can schedule treatment early in the morning and have the rest of the day to work or play.
  • There is usually no impact on a patient's energy level and no recovery time.
  • Significantly lower chances of secondary cancers later in life.
  • Overall, there are fewer, if any, side effects compared to other treatment options.

The Book You Need to Read

BOB founder Bob Marckini has written a book that removes much of the mystery, confusion, and fear about what to do when you are diagnosed with prostate cancer. Speaking from personal experience as a "graduate" of the Loma Linda University Cancer Center proton treatment program in 2000, he makes a strong case for considering proton therapy as a viable option for avoiding radical surgery and other treatment options that typically cause debilitating side effects. 

The second edition of You Can Beat Prostate Cancer: And You Don't Need Surgery to Do It is available.

BOB Blog

Jim Tuggey was treated with proton therapy for his prostate cancer in 1999. He started this blog to help others learn about the treatment from a patient's perspective. After his passing (unrelated to prostate cancer), his nephew handed the blog over to us. We're honored to keep it going.
