Vena Cava Syndrome

This is the result of tumours in this dog’s neck squeezing the veins so that the blood pressure in the head increases causing swelling.

Transmissible Venereal Tumour

There are only 2 cancers that are truly infectious, the other in Tasmanian Devils. There are many that are caused by viruses, but with disease, the cancer cells themselves actually infect other dogs. The disease is passed through contact with the genitals either at mating or when dogs just investigate each other. It is most common in the tropics and with stray dog populations. It is cured with chemotherapy.

Perianal Epithelioma

This growth is typically not very aggressive and curable by surgery. Note the position of the mass (which can be anywhere in the general area around the anus) compared to photo #1 showing the anal sac carcinoma.

Oral Carcinoma

Dr. Ken — Thu, 04 Jun 2009 08:51:15 +0000

Both these photos show squamous cell carcinoma. Many dogs will be cured of this disease. Surgery is the most reliable treatment to gain initial control however some dogs will do with medical treatment alone.

Metastatic Melanoma

This xray could be describing just about any advanced cancer – normally the lungs are black with lines (airways and blood vessels) running through it all of the white patches that look like cotton wool are cancer growths. The dogs head is to the left.

Mast Cell & Nose Tumour

Dr. Ken — Thu, 04 Jun 2009 08:46:53 +0000

Photo 1 shows a typical low grade mast cell tumour whilst 2 shows a high grade version. Most are in the skin, or just under it, but occasionally they occur in the mouth or the nose.

Hemangiosarcoma Eye & Tongue

Dr. Ken — Thu, 04 Jun 2009 08:42:20 +0000

This is literally a cancer of one of the cells involved in building blood vessels. Not surprisingly, the tumours look a lot like a blood blister. They can range from benign to highly malignant.

Haemangiopericytoma

Dr. Ken — Thu, 04 Jun 2009 08:39:18 +0000

This tumour is a ‘soft tissue sarcoma’ meaning it has grown from connective tissue. All the tumours in this group tend to be very invasive but most commonly do not spread elsewhere.

Melanoma

Dr. Ken — Thu, 04 Jun 2009 08:36:50 +0000

This form of melanoma can sometimes be removed from the eye, sometimes WITH the eye. Either way it is typically curable.

Cutaneous Lymphoma
