Hi, thanks for using Petco Pet Education Center, formerly Petcoach! The most common oral cancers in cats is squamous cell carcinoma at 80% (SCC) and fibrosarcomas. SCC is very locally invasive and removing the mass usually requires significant removal of tissue/bone. Cats tend to not tolerate this extensive of oral surgery and would require feeding tubes post operatively. It is very commonly involves the tongue which is even worse for the quality of life for a cat. Sadly most of the tumors are found when they are too large to be removed and are deemed inoperable. After aggressive surgery then radiation would be recommended if the surgical margins were not clean. Radiation alone in cats has been not found to be helpful. I hope this helps and I wish you the best!
