My 8-year-old cat has a sudden lump and is losing weight. What is it?

Question

I just discovered a large lump on the front side of my cat and it just appeared today. What could it possibly be? He is around 8 years old, and can't seem to keep weight no matter what we try. Pet's info: Cat | Mixed Breed | Male | neutered | 9 lbs

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!
