i fucking hate cancer

so i was giving travis a bath today and as i was scrubbing his legs i noticed that his right front leg (the one that only has 3 toes now) was thicker than his other front leg. upon closer inspection a bit later, i noticed that he has a sort of circular growth on this leg that seems to branch up the leg...i knew that the cancer would come back but i didn't think it would so quickly.

he still acts ok- still eats, drinks, wants to go on walks, goes to the bathroom normally and runs around like a puppy. i don't know if he is in pain, but he is on dermaxx for arthritis, so it may be masking it. he did drag me down the street on a really long walk today...the longest we have walked since his second toe amputation back in august. so i am really upset, and i don't know what to do. i think i'm going to have jeanne look at him on tuesday, but there is probably nothing that she can do, short of amputating his little leg...and i will not go for that. i fucking hate cancer.
