[|Human|] Hello I have developed a small (pea sized) lump on the side of my left testicle. It is on the testicle on not epididymus. I am 65. I had a vasectomy 35 years ago. There is no family history of testicular cancer, or any cancer come to that. My Granma died in her 90s of colon cancer. That is all.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have some cyst or testicular tumor. You should go for ultrasound study. Then you should take treatment according to diagnosis. Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
