Causes/Predispositions: No one fully understands what causes cancer. Mast cell tumors are very common in dogs, yet they occur far less frequently in cats and very rarely in human beings. They occur in dogs of all breeds, ages, and genders and can occur anywhere on the body.
To check a lump for cancer, your vet will use a needle to get a sample. If itâs just a fatty tumor, he may suggest to do nothing and watch the tumor. If it changes or gets bigger, he may suggest a treatment. Mast cell tumors can also appear on the catâs skin, usually on the head or neck. They may be itchy or red.
