It's easy to think that breast cancer is a woman's disease.
And it is true that breast cancer is almost 100 percent more likely in women, but one person who'll be pounding the pavement at the Race for the Cure is spreading the word that it can happen to men, too.
Breast Cancer Survivor Mark Goldstein explains how he was diagnosed, "I went into the operating room not knowing that I had breast cancer, came out one breast light and that was the beginning of one of the most positive experience of my life!"
Since Mark's post-operation diagnosis, his mission has been to spread the word.
He's run in every race for the cure in 47 states at least once and run internationally as well.
But at first, the women's world of breast cancer wasn't receptive to his cause, Mark told us the story of the first time he ran: "We got our bibs, showed up the race people said we couldn't run because we're men. And I said, 'Look, I had a modified radical mastectomy, chemo, radiation lymphedema...except for the genitalia, I fully qualify,' and off we went!"
And he has no plans to stop racing. When asked what his goal was, he answered, "God has set that goal for me, and he will tell me when to stop."
When you pass him at the race, as he admits, you're likely to do, his message will be obvious.
Men shouldn't die of breast cancer out of ignorance.
Many times breast cancer in men is more fatal than in women, because men don't know what to look for.
Here are the warning signs:
-A lump or thickening in your breast tissue
-Changes to the skin covering your breast or nipple
-Discharge from your nipple.
If you have any of those symptoms, see your doctor right away.
