<human>: (Testicular Cancer Problem) Background Male Asian(Chinese and Cambodian)-American age 19~20 Problem: I just recently self examined myself for testicular cancer, but I can not currently tell exactly what I am feeling. Both my left and right testicles have no problems as in: no bumps on them, and no other weird feeling;however there is a distinct difference of the epididymis(i think ) between the left and right one. My left testicle seems to be covered/overlapped(closer towards the body side) by a rather large amount of material(the material is squishy and the amount is approximately the same volume as the testicle). My right testicle does not have such large material, but I do feel it having the epididymis. I also do not have/feel any of the symptoms from testicular cancer. Question: Should I immediately see my doctor? or Should I ask my doctor whenever I see him/her again?
<bot>: You probably have what is called a varicocele. This is nothing but a dilation of the veins of the testicle. This is not cancerous and does not lead to cancer. Lie down on the bed and hold your left testicle slightly raised. After a while, the swelling will disappear. This is diagnostic for varicocele. It is not urgent but when you meet your doctor, get an ultrasound of the scrotal area and of the whole abdomen done. Sometimes, varicocele is due to a kidney tumor which one must rule out.
