My cat has something inside his rear thigh. Does not seem to be painful when

What tests can a vet do to find out if he has cancer?
Are the tests reliable?

He has no energy and is not eating well.

If he does have cancer what can a vet do to make him more comfortable?

Please take the first step and get him to a vet immediately. It could
be a number of things, including a cyst to a simple abcess. Lethargy
and lack of appetite means he is not feeling well. Don't wait in
bringing him in.
