My cat has a raw, irritated lump near her nipple. Is it cancer?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 13 years and 9 months old | 8 lbs

Cat has irritated lump on stomach, possibly near nipple. Red and raw, likely due to licking or scratching, seems irritated. Spot is characterized by a small bump or nodule under the skin in the affected area. Wondering if this is cancer, an abscess, an infection, or something else. Has been present for at least 4 months with no apparent irritation or discomfort to cat. Recently started rubbing/licking/irritating the spot to the point that it has become raw as described above. What is it?

Hello, sorry to hear about Diamonds. My biggest suspicion is that she may have a mass below that area which could be cancerous. The best way to know would be to obtain a sample from the mass and look under the microscope for potential malignant cells. Alternatively, this mass could be removed and submitted for biopsy since it is bleeding and likely causing Diamonds some discomfort. I would recommend having you veterinarian assess the mass and decide wether removing or sampling it is the next best step. Hope this helps and best of luck.
