Nobody has put this up yet. I’m a testicular cancer survivor (7yrs knock, knock, knock).
First: CHECK YOUR TESTICLES FOR LUMPS!!! Once a month in a hot shower.
Second: Testicular cancer and other cancers (certain carcinomas) cause HCG levels to go up, which cause your estrogen levels to rise, thus you can get gyno from that. So, if you have gyno what ever the cause you think it might be it is a good idea to have your doc run a Beta-HCG blood test to make sure things are in order.
Especially if you are experiencing gyno out of the blue. First check your nuts, than go to the doc. I don’t post here too often but I think it might be a good idea to make this one sticky. Even if it helps just one person out to catch something in time. I personally think men don’t get told enough to check themselves.
