Occasionally we discover a small lump at our pet. Usually, there is no reason to panic at all. But in general, it is advisable to have this lump examined by the vet. It can be a simple inflammation, but it can also be a more or less annoying tumor. Some tumors appear to be very harmless, but can still have unpleasant consequences.
Besides the visible tumors, some tumors are in the internal organs and, therefore, not visible on the outside. They can cause all kinds of symptoms, such as anorexia despite good appetite, vomiting, diarrhea, etc.
