Skin Lumps and Bumps in Cats
Fibrosarcomas are cancerous tumors that can appear anywhere on the body. Rarely, they happen as a side effect to a vaccine. If your cat has a lump at the site of a recent shot, let your vet know. He may ask you to watch it for a few weeks and visit the office if it doesn't shrink away. Usually, these tumors happen long-after the vaccination.
One of the most common types of cancer to affect cats is breast cancer, or mammary gland tumors. They appear on the underside of the cat, near her nipples, and often go unnoticed until they’re large. At the start, these tumors may feel like BB pellets. If you spay your cat before she goes into heat for the first time, you'll cut her breast cancer risk by about 90%.
If your cat has any type of cancer, she will most likely need surgery to remove the tumor and the tissue around it. Your vet may refer you to a veterinary oncologist, who treats animals with cancer.
For breast cancer, removing the whole mammary gland may be the best treatment. In some cases, the doctor may recommend radiation or chemo after surgery.
Just like people, some cats have blackheads on their chin or face. These can feel like very small bumps under the surface of the skin. They may be easier to notice if they become infected. If your vet says that your cat has acne, he may ask you to use a special wash or medicine on your cat’s face to remove extra oil.
If your kitty stays inside, you may not think of this, but indoor cats can get ticks. The parasites can hitch a ride inside from dogs or humans who spend time outdoors. If a tick stays on your cat's skin long enough to embed itself, it can look and feel like a lump.
If it’s a tick, your vet can safely remove it. He may also do a blood test to see if your cat has the feline form of an infection similar to Lyme disease, which humans get from ticks.
