Is pain associated with testicular cancer constant or comes and goes/varies in strength?

Painles: Initial stages of testicular tumor appear as pain less growth with no testicular sensation then spreads to abdominal nodes , and a reason for delayed diagnosis. For any swelling in the scrotum must see the physician for early diagnosis and cure.

It varies: Testicular cancer often presents as a painless mass, but this is definitely not a rule, and it may be painful. Any lump (mass) of the testicle should be brought to a physician's attention asap.
