My cat is a 6 month old domestic long haired cat and he has a small lump (about half the size of a marble) on his hip, on the outer side of his body, the lump has a trinagular shape, leading it to feel a bit like a cyst, but it is firm. He feels no Pain when I examine the area or push on it. Could this be a tumor?

I am sorry to hear about yoru concern for Solomon! While it is rare for us to see tumors in a cat so young, it is possible to have this occur. I would not leap to that conclusion without further investigation however, as this could be something like a benign cyst, an abscess, a foreign body under the skin, or a granulomatous reaction to a previous vaccine. I would recommend having your vet examine the area. They may recommend an aspirate of the lump with a needle to help identify what is going on and guide their plan of treatment.

Ouch, that spot looks pretty uncomfortable. I would at least have it checked out by your vet, as a biopsy may still be the best option to confirm what it is, and then go from there. Your vet can then recommend any treatment options, such as if surgery would be viable, or how to best keep Anja comfortable if treating it otherwise isn't an option.
