Cancer in cats is the leading cause of death in older cats. According to the American Cancer Society, cancer is a group of diseases
characterized by uncontrolled growth and spread of abnormal cells.

Spotting cancer in your cats will be tricky. Visible symptoms of cancer include tumors or sores that can appear almost anywhere on the cat's body,  difficulty breathing, and unexplained bleeding, discharges or significant changes in energy level, eating, bathroom and sleeping patterns. The most critical thing is that if you see a tumor on your cat or think that he may be sick, make sure to get him checked out as early intervention will be key in keeping your cat healthy.

As with humans, scientists do not have a clear answer as to what will cause cancer in cats. Since we do not know  what causes cancer in cats, it is almost impossible to prevent a cat from getting cancer. A strong immune system is a critical component of overall cat health and supplements that boost your cat's immune system will likely help improve the overall health of your cat. If your cat has a stronger immune system, it will help your cat avoid getting cancer (as well as other illnesses) and can help cats that already have cancer recover.
