Myth #1

Proton therapy is experimental and investigational. It is a new, untested science. Learn the truth.

Myth #5

Myth #6

My doctor tells me that the only way to be sure I’m cured is to have the prostate removed from my body. With proton therapy, the prostate is left behind, so my chance of a recurrence is higher. Click here to learn the truth.

Myth #7

There is no data/statistics available to support the success of proton therapy. Click here to learn the truth.

Myth #8

Proton is radiation, and that means I am at risk for secondary cancer from proton treatment later in life, just as I am with IMRT. Click here to learn the truth.

Myth #9

If protons were so good, than [fill in name of prestigious institution] would have a proton center. Learn the truth.

Myth #10

I can't afford to take the time away from work and family required for proton therapy. I can get my treatment locally in a much shorter time and expect the same results. Learn the truth.

Bonus Myth

My urologist tells me I’m not a good candidate for proton therapy because I’m a young guy and that young men should have their prostate taken out surgically. Learn the truth.
