Thank you for your query at DoctorSpring.com
I understand your concern.
I shall be keen to know the exact location of the lump. I shall be interested to know whether it is within scrotal sac or penis shaft or at the root of penis.
There is a good possibility that you are having calcified plaque within the corpora of penis. The condition is known as Peyronie's disease and nothing needs to be done for the same if it is not troubling you.
Feel free to discuss further,
Patient replied :
I am not sure if it's on my testicle or high up and between my testicles. Is it safe to say it's not testicular cancer if an ultrasound was done a year ago and the urologist found nothing?
Let the doctor examine you and see what is the location of this lump.
An ultrasound done 1 year back and normal; is highly suggestive that you don't have cancer.
