It doesn't help that life or death issues for men, like testicular cancer, are almost completely ignored. About a decade ago, I had the same concern as you and after a scary doctor visit (which included his female assistant observing, which added to the discomfort but that all mitigated by the more terrifying prospect of this being a life-threatening concern) followed by an ultrasound at the hospital, I was relieved to find out it was nothing to be worried about.

After that, though, I started to think. I realized that the only reason I knew to be concerned was because just shortly before that, I'd heard Lance Armstrong's story in a sport's magazine.

I realized that every single male 20-34 knows about breast cancer and ovarian cancer and that women are supposed to be regularly checked all all of these concerns promoted by countless events and product promotions and charities . . . but very few of them probably have the slightest clue about their own medical concerns that they should be looking after. Because nobody bothers to emphasize the need to inform them and educate them.
