Mammary Tumors in Dogs and Cats
Mammary tumors are common in intact female dogs and are the third most common feline tumor. They often appear as firm nodules in the mammary chain and can ulcerate or spread to lymph nodes and lungs. Early spaying sharply lowers risk, and surgery is the main treatment.
Cutaneous Fibromas in Dogs and Cats
Cutaneous fibromas are benign tumors that arise spontaneously or after injury and can occur anywhere on the skin of dogs and cats. They are well-defined, hairless, and rarely ulcerate, and small ones may need no treatment. Surgical removal cures most cases.
Cutaneous Mast Cell Tumors in Dogs and Cats
Cutaneous mast cell tumors can appear anywhere on the skin or internal organs, most often on the hind legs, perineum, and prepuce. They vary from slow soft lumps to fast hard nodules and may ulcerate. Surgical removal of well-defined tumors is the main treatment.
Fibrosarcomas in Dogs and Cats
Fibrosarcoma is a malignant tumor of fibrous tissue and the second most common mouth tumor in dogs. About 60 percent arise in the skull bones and 30 percent in the long bones. It is firm, invasive, and bleeds easily when sampled. Surgery is the main treatment.
Papillomas in Dogs and Cats
Papillomas are benign tumors of the skin's outer layer, among the most common epidermal tumors of dogs and rare in cats. They appear as cauliflower-like, often stalked warts that can bleed when injured. Many regress on their own, while others are removed surgically.
Melanomas in Dogs and Cats
Melanomas are pigmented tumors that may be benign or malignant, often in dark-skinned dogs such as Cocker Spaniels and Scottish Terriers. They favor the mouth, eyes, rectum, and perineum, with mucosal sites most at risk. Wide removal is used, but malignant forms carry a poor outlook.
Lipomas and Liposarcomas in Dogs and Cats
Lipomas are common, usually benign fatty tumors made of fat cells that grow slowly under the skin and rarely cause problems. Liposarcomas are the malignant form and can invade and break down. Solid lipomas are removed surgically, with weight control helping recovery.
Squamous Cell Carcinoma in Dogs and Cats
Squamous cell carcinoma is a skin tumor of the epidermal layer linked to long-term sun exposure and other skin irritation. It is the second most common skin tumor in cats and favors the head, ears, lips, and nose. Wide surgical removal is the main treatment, though it often recurs.
Sebaceous Adenomas in Dogs and Cats
Sebaceous adenomas are usually benign, curable skin tumors of older dogs and cats, most often on the back, sides, limbs, and head or neck. They appear as firm, movable, hairless lumps that may ulcerate. Complete removal or freezing cures the benign forms.
Basal Cell Tumors in Dogs and Cats
Basal cell tumors are common, usually slow-growing skin tumors of dogs and cats that arise from the basal layer of the epidermis or hair follicles. Most are benign and stay confined to the skin, though larger ones can ulcerate. Complete surgical removal is typically curative.
