Mild right varicocoele, minimal left hydrocoele, tiny cyst in the right epididymis found in u/s. hypochondriac of testicular cancer. what should i do?

Lets treat Hypochond: You have to trust your test results and your treating doctor. If you do not, then we need to treat your hypochondriasis. Testicular cancer is not a subtle condition. It will produce a growth in the testicle which you can feel with your hands (bigger than the other testicle) and ultrasound will show it up easily. So just relax, think of better things to do than worry(you should wait to worry!).
