Bladder Cancer in Dogs

This is the most common of the Canine Bladder Cancers; however there and two other types - Leimyosarcomas and Fibrosarcoma. TCC is a tumor cell that lines the bladder wall. The symptoms are similar to those of a Urinary Tract Infection, UTI, which include frequent, small urinations, blood in urine, and incontinence. It is common for the cancer cells to spread to lymph nodes in the abdomen.


Bone Cancer in Dogs

Bone cancer in Dogs is usually more common in the larger breeds and onsets once the dog reaches "middle age." Most common are the limb bones (75% - 90%) known as Appendicular Osteosarcoma. As with many Dog Cancers, the causes are still unknown; however, rapid growth and early neutering have shown increased cases.


Breast/Mammary Gland Cancer in Dogs

These are tumors that are most common in unsprayed, female dogs, especially "Toy" dogs such as poodles, spaniels as well as German Shepherds. The occurrence is usually in older dogs in the ten plus year group. The tumors can grow at different rates and symptoms are difficult to recognize, as dogs tend to not show signs as with other cancers. Concerns are the rapid spreading to lungs and lymph nodes.

Causes are primarily genetic predisposition though full understanding of the onset is uncertain.


Glandular Cancer in Dogs

Tumor that is found in glandular tissue and often spreads quickly to the lungs, liver and lymph nodes. There are no real symptoms and causes are uncertain.


Liver Cancer in Dogs

Malignant tumor of the epithelial tissue in a dog's liver. There are also more benign liver tumors; however this type accounts for about half of the liver cancers that affect dogs. Common symptoms include loss of appetite, weakness and loss of interest and energy, diarrhea and weight loss, enlarged liver (Hepatomegaly) and vomiting.

Causes are unknown but environmental conditions; diet and toxins are believed to be major causes along with genetic predisposition


Lung Cancer in Dogs

usually a malignant tumor in the epithelial tissues. Typical symptoms are dry coughing and affect all breeds. One of the major causes is environmental condition, including second hand smoke. Other indications of canine lung cancer include weakness, labored breathing, lethargy, and blood in coughing (usually late stage).


Mouth - Oral Cancer in Dogs

These tumors usually develop along the gingival surface areas and are very aggressive. They usually appear in the upper mouth region or around the upper teeth. Thee aggressiveness of their growth causes the cancer to quickly spread to bone and then other areas of the body. The onset can be as early as six to twenty months.

There may also be growth in mouth and swollen glands in neck. There may even be external swollen areas around the eyes and other parts of the face. Symptoms are loose teeth, unusually bad breath, bleeding of the gums and difficulty eating, which can lead to weight loss. There are no known causes for canine oral cancer.

Pancreatic Cancer

Rapidly growing malignant neoplasms, or fast growing cancer cells, much the same as in humans. The cells exude high levels of insuline directly into the blood stream causing both weakness as well as possible neurological problems.

Symptoms may include lethargy to complete loss of consciousness. The randomness of insulin release may make certain awareness difficult as the symptoms are not constant. Pancreatic cancer in dogs is rare and usually occurs in older dogs. Boxers and Airedales tend to be at higher risk than other breeds.


Prostate Cancer in Dogs

BPH is an increase in the size of the prostate gland itself. It is a result of testosterone and starts to affect male dogs around the age of 5. This is a benign condition. Canine Prostate Cancer is rare in dogs and is not influenced by testosterone, so both neutered and unneutered males can be affected by it. It is difficult to identify symptoms as there really are no visible signs, so preventative measures, such as I'm Yunity, and consistent check-ups with one's vet are important to reduce the risk.


  • Mast Cell Tumor: the most common of the skin cancers. No real cause is known; however, genetic factors seem most likely as well as irritants.
  • Malignant Melanoma:this cancer spreads quickly and is often found near the mouth and pigmented cells that do not metastasize. Genetic factors are the most likely cause
  • Squamous Cell Carcinoma: This is a cancer that is likely caused by exposure to the sun, such as nose and pads on feet where there is no hair. Light colored or very thin coats also play a factor


Spleen and Heart (Visceral) Cancer in Dogs

A very aggressive, soft tissue sarcoma. Though it can affect other areas, including skin, the spleen and heart are the most common areas. Hemangiosarcoma is an aggressive, malignant tumor of blood vessel cells. It is one of the most serious tumor diagnoses.

When a Splenic Mass is diagnosed, splenectomy is required to determine malignancy. Preventative measures, such as I'm Yunity, can assist to deter the onset and possible growth and spreading of the tumor. Even with removal of the spleen, bleeding can still prove to be a symptom and spreading malignancy is still likely.

Visceral Hemanglosarcoma of the heart is a life threatening condition and is connected with bleeding. Blood tends to fill the pericardium, or sack which encloses the heart. This in turn builds pressure and the heart cannot perform properly.

While the Dermal or skin version of hemanglosarcoma is sun related, it is uncertain as to the causes of the spleen and heart versions. Certain dog breeds, such as Golden Retrievers, have higher incidents, so genetics and breeding are likely causes. The onset usually starts around the age of 5 or 6 and increases with a dog's age. Other breeds that are very susceptible are German Shepherds, Boxers, Dobermans, all Retrievers and Setters, and other larger dogs.

Hemanglosarcoma can also be found in the liver, bone and lungs.


Stomach Cancer in Dogs

Canine stomach cancer is rare in dogs and usually affects males more than females. The symptoms are hard to see in early stages, which is why this is a dangerous cancer. By the time the dog shows any signs of illness, it's usually in late stages. There are two types of cancer that can affect a dog, benign and malignant, which is the most common.

The two most common malignant stomach cancers are Adenocarcioma and Leiomyosarcoma . Extramedullary Plasmacytoma and Leiomyomacan are usually benign and are usually treated with surgery. The malignant tumors often spread quickly to lungs, liver and lymph nodes.

Collies, Bull Terriers, Belgian Shepherds and Chow Chows have been breeds with the highest incidents of stomach cancer. Vomiting, drooling, loss of vitality and appetite are also signs. Black stools indicate internal bleeding. Causes vary, but genetic predisposition and environmental and diet are probable contributors


Testicular Cancer in Dogs

Testicular Cancer is one of the most common tumors to appear in older male dogs that were never neutered. There are three basic types of testicular cancer, Sertoll Cell Tumors, Seminomas and Interstital Cell Tumors.

Symptoms can be swollen testicles and scrotal region in all cases; however, less so in Interstital Cell Tumors. Swelling may also occur in the abdomen and prostate. Other areas that might be affected can be enlarged mammary or nipple areas as well as hair loss. Treatment is usually castration.


Thyroid Cancer in Dogs

Thyroid tumors usually develop along the thyroid gland trenches but these tumors rarely interferes with the hormones the thyroid gland produces; however, levels must be checked. Thyroid tumors can spread or metastasize to other parts of the body. Treatment is usually surgery or radiation.

Symptoms can be weight loss, increased heart rate, hypertension increased energy levels. There are a number of possible causes of Thyroid cancer in dogs, but the exact reasons are uncertain. One possibility is that the immune system works to destroy the thyroid. Other causes are probably genetically based. It can occur in dogs of any age, but usually onsets between the ages of four to ten. Common dogs to be diagnosed with this cancer are Golden Retrievers, Cocker Spaniels and Irish Setters.
