2. Enlarged veins around testicles

If you are a guy reading this post, the next entry will terrify you. In some cases of kidney cancer, a male patient suffers from varicocele. A varicocele occurs when veins become bigger inside your scrotum (the bag-like skin hanging that holds your testicles). This process is severely painful and eerily ugly. Imagine a vein-like pattern bulging on your testicles – that’d look awful.

Varicocele also causes one or both testicles to shrink. People suffering from varicocele are often unable to have kids.

Since kidneys are connected to the overall urinary process, any malfunction in them causes an instant effect on testicles and everything related to pee.
