Lump Right side

  I went to the doctors after feeling a lump the size of a pea just below
  my right testicle  The Doctor told me I was epididymis and it usally comes
  drom riding bycles, horse back riding etc.  He place me on Vibramycin and
  told me it should be cleared up in about two weeks. If it did not
  go away to come back.  I had a vassectomy about 1 year and half ago.  It only
  hurs when I or my wife touches it . Should I be conserned?

Dear Doug,
Lumps outside the testicle can arise from a variety of structures. There are two main structures in the scrotum. These are the testicle and the epididymis. Cancer of the epididymis is extremely uncommon. However, lumps and bumps associated with it are quite common. Spermatoceles are collections of sperm that arise from the epididymis and become walled off bumps. They are completely benign. Hydroceles are collections of fluid. These are also completely benign. They can occur for a variety of reasons including surgery, trauma and infection. Also, you mentioned that you had a vasectomy. Scar tissue formation called granulomas are quite common in this setting.
A mass of the testicle is much more reason for concern. Testicular cancer is now one of the most  treatable cancers when detected early. A mass is the most common presenting complaint. The easiest test to determine the cause of your lump is a scrotal ultrasound which is both quick and painless.
