Quick history I was diagnosed with pure seminoa testicular cancer(stage 1a) last year. During the last few months I've been noticing pronounced weight lost, grion pain, and the lump I noticed last week. This all has happened in the last 6 months. The lump seems to be above the muscle on my lower abdomin near my belly button( like a inch and a half southeast if you were to lay the cardinal directions on my belly button, best way I can think of describing the location I'm not a doctor) the lump is soft and doesn't move. Thanks for the time.
