Bladder cancer is the fourth most common cancer among men, but if caught early is treatable.

David Crockett, 53, wasn't doing so well after a 10K run in 1991.

"I had blood in my urine after the run, so I did what any good soldier does. I went on sick call and told the doctor what it was, and because it happened after a 10km run he said well that happens sometimes when you run. So I let it pass," Crockett said.

But it kept happening for a year-and-a-half.

"When it started happening when I didn't run, I realized this is not right and I should probably get that checked out," Crockett said.

It turned out he had bladder cancer and a tumor the size of a racquetball which required surgery.

"I don't meet any of the risk factors. All of the risk factors are smokers, and older men. I think the average age of someone who has what I have is in their 70s," Crockett said.

"The most common risk factors are age, gender which is more common in men, and tobacco use. Not just smoking but any form of tobacco and secondhand smoke," said Dr. Robert Svatek, UT Health Science Center Urologic Oncologist and Assistant Professor.

"I never smoked a cigarette in my life. I never even experimented with it," Crockett said.

Even if you don't meet any of the risk factors, if you see blood in your urine you need to get checked out ASAP.

"Sometimes patients get delayed by treating it with antibiotics or things like that, and that substantial delay can result in progression of the disease," Dr. Svatek said.

"If it pops up more than once than that is something you should get checked out because although the norm is someone in their 70s it's not exclusive,” Crockett said.

The second you see blood where it isn't supposed to be, head to the doctor so you can avoid wearing that gown as much as possible.
