Dog Cancer Lumps

Principally, there are 2 kinds of lumps: benign lumps and malignant lumps. It is extremely imperative that you keep a watch for the development of any lumps on your pet. Also, keep track of changes occurring in the lump. It is also vital to watch out for any other manifestations and symptoms in the dog. An early diagnosis helps embark up on the most optimal treatment promptly.

Types of Dog Cancer Lumps

The following are the commonly seen dog cancer lumps. They are discussed in detail:


Warts may develop due to viral infection. They may appear anywhere on the body. Warts are commoner in older dogs because of a weak immune system. A wart is benign and can easily be treated with medications.

Abscess and Hematoma

An abscess is pus filled and occurs near an injury site. It is a benign lump. A hematoma is a blood filled growth that also occurs near injury sites. It develops due to an impaired clotting system.


A lipoma is a fatty lump that affects over-weight and middle aged dogs. They invariably develop near the belly and are hardly ever malignant. They need to be excised surgically.

Sebaceous cysts

A sebaceous cyst occurs due to an abnormality in the gland of the skin. A cyst is filled with fluids or debris. These are the commonest dog lumps, and are benign.

Squamous Cell Carcinoma

The squamous cell carcinoma is a malignant lump. It can be excised surgically; also, chemotherapy is quite effective.

Mast cell tumor

Mast cell tumors are malignant lumps and are quite common. Their diagnosis and management is relatively difficult, since their appearance varies from breed to breed.

Diagnosis of Dog Cancer Lumps

To diagnose a lump, the vet will use a needle to aspirate the cells from the lump, or the lump is discharging, the fluid is collected on a slide and investigated.
Tissue culture also helps find out whether the lump is benign or malignant.

Treatment of Dog Cancer Lumps

If the lump is benign, the doctor will surgically cut out the lump, or prescribe medications to treat it. For malignant lumps, surgery, in combination with radiotherapy and chemotherapy is used.

Also, regular check ups of dog cancer lumps are necessary. If a lump has been diagnosed as benign, you must get it checked periodically. In rare cases, benign lumps may turn malignant.
