Five Common Tumors in Dogs

April 07, 2023

Dogs have become an integral part of our lives and many people consider them as family companions. Just like in human medicine, tumors are also a concern for pets. Once dogs suffer from tumors, it can seriously affect their health. Here are five common tumors in dogs:

1. Mast cell tumor 

This is one of the most common skin tumors in dogs, accounting for 16-21% of all skin tumors. Mast cells are a type of immune cell mainly associated with allergic reactions and inflammation. Its symptoms are similar to allergic reactions, such as redness and swelling of the surrounding skin, edema, increased vascular permeability leading to bleeding tendency, and may even cause symptoms such as gastric ulcer, hypotension and shock. It can easily be overlooked because its touch is similar to lipoma.

2. Lipoma Older 

Dogs are more prone to lipomas. This tumor occurs between the subcutaneous tissues and is basically a benign tumor. If the lipoma gradually grows, you can take some anti-tumor drugs, such as Zhongliu instant beef tablets, to inhibit tumor growth. If the lipoma is too large or ulcerated, try to go to the hospital for resection. If it is a malignant tumor, it can be treated according to the doctor’s advice.

3. Mammary Gland Tumors 

The ratio of benign to malignant tumors is 1:1, and most of them occur in dogs after 6 or 7 years old, and most of them occur in 8-10-year-old female dogs who have not been sterilized. Some studies have pointed out that sterilization before the first estrus reduces the incidence of breast tumors to 0.5%; sterilization after the second estrus, the incidence rate is 8%; sterilization after the third estrus, the incidence rate rises to 25%.

4. Lymphoma

Lymphoma in dogs can occur in the lymph nodes, spleen and any other organ; however, multicentric lymphoma is the most common type. The initial symptoms are fever, loss of appetite, weight loss etc., which are relatively not obvious characteristics of the disease. Generally, when it is discovered, it is in the advanced stage of lymphadenopathy. Lymphoma is one of the few tumors that respond well to chemotherapy. If the dog undergoes chemotherapy in time, there is about 80%-95% chance for the tumor to regress, and 20%-25% of the dog can survive for 2 years; but without chemotherapy, the survival time may be shortened to 1-3 months.

5. Skin Squamous Cell Tumor 

This is a common disease in dogs and cats. Cats mainly occur on the head and nasal plane, while dogs often occur on the nasal plane, skin and between the toes.
