This is Dr. David. I am reviewing your question now and will be with you momentarily.
sorry your doctor found a mass between your testicles.
that is good the biopsy showed it is non cancerous.
the biopsy report and ultrasound can give more information about what the name of the mass is.
it could be paratesticular fibrosis mass or scar tissue formed to sperm called sperm granuloma.
I bet the incision is only 4cm in length, not 4 inches.
you should feel fine after the surgery
you may need 1-2 weeks off work, but you may be able to go back to work after 1-2 weeks
let me know if you have questions.
let me know if you would like me to call you.
