Melanoma in a Feline

Iris Melanoma

• Iris melanoma is a cancer of the eye frequently found in cats. The cancer is a tumor that corrupts the eye to the extent of blindness if left untreated. Since tumors grow rapidly, early detection is critical in preventing further deterioration. Signs of iris melanoma in cats include freckles on the eyeball and discoloration of pupils.

Treatment and Prevention

• Preventing iris melanoma is a matter of monitoring felines closely for signs of development. It is best to take cats to ophthalmologists periodically for comprehensive examinations. If iris melanoma is discovered, seek laser treatment to remove the tumors. In many situations, complete blindness and further infection can be avoided if the condition is discovered and treated in its early stages.

Dermal Melanoma

• Dermal melanoma is a form of skin cancer rarely found in cats. Although few cats develop the disease, the percentage of felines with dermal melanoma increases in older cats. These cats usually show signs of the disease with freckles or moles on the forehead and eyelids. Detecting dermal melanoma is often a matter of thorough observation that involves looking beyond the fur of a feline. Individuals should seek professional help immediately if moles or freckles are found on the skin.

Treatment

• There are several treatments available for dermal melanoma. The most common and effective remedy is radiation therapy. In this treatment, the cat is exposed to radiation waves that serve to remove the cancer. Gene treatment is also available to felines and often proves effective since the disease tends to be genetic in some cats. Chemotherapy is an ineffective form of treatment for dermal melanoma in felines.
