I can understand your concern here. This appears to be either a severe inflammatory reaction or a skin tumor, and it can either be a benign (non-cancerous) tumor or a malignant (cancerous) tumor. The only way to determine which is likely is to have your vet take samples of the tumor/mass and send it off to the lab. The area also appears to be infected, in which case a short course of antibiotics will be needed. Because of the large area that it covers it likely can't be surgically removed but there may be other treatment option available through a veterinary oncologist referral if it does indeed come back as a cancerous tumors. This does not appear to be anything that is contagious to people, but again having it tested is the next best step. I hope that everything works out for your pet Princess. Best wishes and take care.
