Hi, For about 6 monts , i have noticed mt left testicle seems to have a swollen vein that is growing. When i take a bath this area seems to float up and is more noticable. I can feel a puufy vein leading from the rear of my scotum to my testicle, now its starting to be more uncomfortable. No real pain though, could anyone tell me more about whats happening, and is the Cancer related, maybe treatment options.
