Pregnancy tests can confirm new life, but it turns out they can also warn of something deadly as well. A Reddit
user, or his friend, found a pregnancy test that was left behind by an ex. He took it as a lark and got a positive result. Upon seeing the post about it several of the site's commenters warned that the hormone that causes a positive test for a pregnant woman is also produced by testicular cancer tumors. This resulted in the man who took the test getting treatment for his early stage testicular cancer. Lucky guy to find out right away like that. The internet has many uses and a few of them have nothing at all to do with porn, who knew?!
