What is Hemangiosarcoma?


Hemangiosarcoma is a rare type of cancer that affects cells in the lining of the blood vessels. Some forms can be very aggressive, so early diagnosis and treatment are key!


There are 3 types of hemangiosarcomas that affect dogs: dermal (affecting the skin), subcutaneous (affecting the layer underneath the skin), and visceral (affecting internal organs).


Between 33-66% of hemangiosarcomas that start in skin cells metastasize (spread) to internal organs. Visceral hemangiosarcomas can happen anywhere in the body, but the organs most commonly affected are the liver, spleen, and heart. Sadly, these types of tumors are the most dangerous, and also the most common hemangiosarcoma in dogs. 



What Causes Hemangiosarcoma in Dogs?


Scientists have identified several risk factors for hemangiosarcoma in dogs. Sun exposure has been linked to certain types of hemangiosarcomas, with pets living in areas with lots of sun, and dogs that have light and thin hair and skin being affected more often.


While middle-aged and older dogs are more frequently diagnosed with this cancer, German Shepherds, Golden Retrievers, and Labradors tend to get hemangiosarcomas more often.




Hemangiosarcoma in Dogs: Symptoms


For dermal hemangiosarcomas, you might notice a red bump on the skin that could bleed. Subcutaneous hemangiosarcomas are usually a lump you can feel under the skin that might be hard or soft.


In the early stages, these tumors are not generally painful, which is good news for your pet, but it can make them harder to diagnose!


If the hemangiosarcoma is affecting internal organs, your pup may experience weight loss, decreased energy, and weakness. Another sign you can look for in your pet is pale or white gums. 


If you notice these symptoms in your dog, make sure to get him checked out right away! They might also be signs of other illnesses, and the quicker you have a diagnosis and start treatment, the better the outlook for your furry friend. 



How Long Can a Dog Live With Hemangiosarcoma?


Unfortunately, it is very common for this type of cancer to spread to other areas, and dogs diagnosed with hemangiosarcoma generally live for 2 months - 1 year, depending on their specific tumors, and treatment options.


Hemangiosarcomas that affect the skin have the best outlook, with an average life expectancy of 6-12 months, but hemangiosarcomas affecting internal organs of the heart have an average life expectancy of only 1-6 months. 



Hemangiosarcoma in Dogs: Treatment


Your vet might recommend surgery and/or chemotherapy as treatment, depending on the type, location, and severity of your pup’s tumor. Even when surgery is recommended, further treatment is helpful to reduce the spread and reoccurrence of the cancer.


Deciding on treatment options for a loved companion is never easy, and can be even harder if symptoms are progressive, and treatment needs to start quickly. There is so much information to consider!
