We saw a specialist for Monster after the biopsy on the mass in his mouth. He has oral squamous cell carcinoma, which in simple terms is oral skin cancer. Because of the location of the tumor, in the corner of his mouth, removing it isn't an option, and radiation or chemotherapy is extremely expensive and isn't known for treating these sorts of tumors very well. Treatment, then, will be to continue with steroid shots, as they control the inflammation and bleeding.
His prognosis is anywhere from a few weeks to a year at most. The vet expects it'll be a few months.
The donations we have received and will receive will go toward his treatment and keeping him comfortable through the remainder of his life, as well as paying for the recent vet visits and the biopsy. As such, I've lowered the amount we need.
Thank you all for the donations we have received, and thank you in advance for any donations we may receive. I appreciate it more than I can put into words.
