Male cat with swollen mammery glands.

March 5th, 2011, 11:30 AM
We have a 2 year old male cate named Vinny. He is neutered. He became ill on Wednesday, March2nd. We took him to the vet and he has the flu. He is much better now. When he was at the Vet, she noticed that one of his mammery glands are swollen. she didn't say much else about it. His stomach was swolen at the time, and it did not seem to concern her much. It does not seem painful to him. He will let you touch, palpitate, and feel around without complaining. Any idea what this could be? I have read articles about diseases that this could be, but he does not have any of the symptoms. Any help would be greatly appreciated.

This is hard to say without seeing him for myself. With that said, here are some possible ideas: if it is localized then bug/spider bites can cause swelling that may not be painful (other bug bites are painful but not all), swollen lymphatic tissue, irregular fat deposit, resolving localized infection. The lymphatic system is a complex network of the immune system and is present all across the body. When the body is fighting an infection or inflammation, lymphatic tissue can become swollen. As long as it is localized (not multiple sites) and resolves, then there is usually not much to worry about.

Whenever I talk to people about mammary masses a few questions keep popping up?

1) Could this be hormonal? In a neutered male cat, this is highly unlikely. Unless further evidence or progression of signs occurred, this avenue should not be worked up.

2) Could this be breast cancer? Male animals (humans, cats, dogs, and especially rats) do get breast cancer. However at two years of age, it is unlikely and if it had a typical malignant presentation, your vet would have said something. Unfortunately one can never truly say that cancer isn't present but this is one of those situation that I would monitor at this point and not be overly concerned about cancer. If the mass does not go away, gets larger, gets more firm or irregular - then I would revisit this and other possibilities.

Warm compress (if he will allow it) and monitoring are good ideas. If it is there after 2 weeks, I would ask your vet to do a quick recheck.

I hope this helps. :pawprint:
