My cat has recurring lumps after vet visit. Are they cancerous?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 5 years and 11 months old | 16 lbs

6 weeks ago we took our cat to the vet with a cyst, she cleaned him up and sent him home with antibiotics but since the antibiotics have stopped we've noticed 2 more. Being tight for cash we can't afford another vet trip. Can this be cancerous or am I just an over concerned cat owner? photo attached is his first cyst after the vet visit. This one has healed but there are 2 smaller ones.

The picture only shows an open wound. I don’t see any tumors to speak of. So unfortunately we can’t tell if the additional masses look suspicous for cancer or not. However this open wound looks gnarly and the tissue doesn’t look happy. And the only way to confirm or deny cancer is to have the masses tested and sent to the lab. However some masses are more suspicous for cancer than others. Please feel free to repost your question with a picture of the masses that you are concerned about and we will be more than happy to give you our opinion. Best wishes and take care.
