If a lump appears suddenly and grows noticeably, take your cat to the vet at your earliest convenience.

Note that their initial tests will be quick, easy, and safe. They can likely be completed while your cat is awake, and will cause little to no pain.

Abscesses are bacterial infections. While they are usually not too dangerous, it’s best to have a vet look at them. They can drain the fluid and prescribe your cat antibiotics to rid their body of infection.

Haematomas need to be evaluated by a veterinarian. There is usually an underlying cause of a haematoma, which requires treatment. For example, it may be the result of ear mites or an infection that caused your cat to damage their ear.

If you’re unsure, the safest option is having a vet check on a cyst and determine whether it should be removed.

Lumps of this sort will be small, pale, and filled with fluid. While the lumps themselves are not dangerous, your cat may hurt itself by scratching.

Call your vet or set up an appointment to have any new lumps inspected.

Benign tumors are generally not a risk to your cat, but it’s worth having a vet check it out. Some tumors that seem benign can still be cancerous. Your vet will likely recommend removal of a tumor on a cat’s face or legs, even if it’s benign. Otherwise, they will likely recommend leaving a benign tumor alone.
