Not necessarily. Once, a redditor got his life saved from that. He posted a Rage Comics post (shows you how long ago this was) where he decided to take one of his girlfriend's pregnancy tests as a goof, and it showed up as positive. The commenters told him that's a sign of cancer, so he got tested, and sure enough, he had a very early stage of cancer, that was so early, it could be nipped in the bud with minimal to no complications.

On the other hand it was a redditor who survived.

yeah but still that makes the punchline of the joke "he has cancer". Not a good joke.

Yeah. Genuinely not fun. Apologies if my initial comment came off as glib.

Some types of testicular cancers produce HCG, which is what most pregnancy tests identify the presence of in urine. HCG could also be used as a treatment method for hypogonadism, but supplementation of exogenous Luteinizing Hormone with LHRH would be a more direct way of both diagnosing and treating hypogonadotropic hypogonadism.

Anyways, if anyone who reads this ever notices something strange on their testis, talk to a doctor. Peeing on a stick isn't a reliable way of identifying testicular cancer, as many forms won't produce HCG and the negative result on the pregnancy test could lead to a false reassurance.
