...will be a while before such dangers arise, though, and--as cancer researchers have discovered all too often--it isn't even certain that what works in mice will work in people. Tsien and his colleagues believe it's not unreasonable to think it will. "The NMDA receptor in humans is nearly identical to the receptor in mice, rats, cats and other animals," he says. "We believe it's highly likely that it plays a similar role in humans...
Although testicular cancer is fairly easy to treat, as cancers go, it is on the rise. An article in the August Journal of Urology reports that the incidence of the disease has shot up 51% over the past 40 years. And while it's typically diagnosed between ages 30 and 35, with a second, smaller peak in men over 65, testicular cancer is now showing up in younger and younger men. Despite its low profile, in fact it's the most prevalent form of cancer among men in their...
...while most undescended testicles eventually get where they're supposed to be, the delay seems to cause some sort of damage: cryptorchidism affects only 3% of the male population but is a factor in 14% of testicular-cancer cases. Doctors have identified other risk factors, such as a family history of testicular cancer, HIV infection and a previous bout with the disease. But none of these explain the dramatic rise in incidence. Other possible risks include occupational exposure to extreme temperatures and the maternal use of fertility hormones...
...good news, meanwhile, is that testicular cancer is one of the least deadly of malignancies: if you include the most advanced stages of disease, it has a five-year survival rate of 95%--and for cases detected early, the rate is 100%. For that reason, many experts suggest that men (of all races) should perform self-examinations monthly, starting at age 15. The best time to do this is after a warm shower, when the scrotum is relaxed and soft. The danger signs include a hard, painless lump attached to the testicles or, less commonly, testicular enlargement or scrotal swelling...
