My cat has a pink lump with a bloody scab and blood vessels. What is it?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 8 years and 8 months old | 20 lbs

My cat has a pea-sized lump on his skin, if I pull the fur apart I can see it. It is not perfectly round. He's 9 years old and in good health. Tonight I noticed the tip of it had some blood on it. I can also see small blood vessels running through it. It is on his back. Left side. I've been watching it for about a year now and it hasn't grown, but just concerned about the reddish scab on top. The growth itself is pink/skin colored. He has always been a nervous wreck/feral and I can't do much.

This kind of lump/growth needs to be ideally assessed by your veterinarian to have a definitive and specific answer. From the picture you uploaded and what you described it looks like a benign type of lump (benign skin tumor) but I cannot guarantee it without examining it. Usually there are two ways your vet can do that a part from examining it directly during physical examination. A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration). Other differentials include skin cysts, infections, benign or more sinister type of tumors. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
