U.S. - Last week, a man who, for obvious reasons, remains anonymous, took an unused pregnancy test left behind by his ex-girlfriend as a joke. After several minutes, the test came back positive. The test results were no laughing matter, as it turned out that the positive pregnancy result could be a sign of testicular cancer.
Pregancy tests work by determining levels of beta human chorionic gonadotrophin (hCG) in urine.
"It turns out a fair number of testicular cancers make the same exact hormone," oncologist Dr. Mark Pomerantz says. "There are very few things in the body that produce beta hCG, and testicular cancer is one of them."
The man with a positive pregnancy test visited doctors who found a small tumor in the man's right testicle. The tumor was luckily caught very early, but he may lose the testicle, according to the updates.
Dr. Christopher Wood, chairman of urology at the University of Texas MD Anderson Canceter Center, says that a painless lump is usually the first sign of testicular cancer, and recommends that men conduct monthly self-examinations.
