Commonly diagnosed cancers in canines

Symptoms of canine cancer can vary in so many ways and the top most common cancer types that occur in dogs are:

Melanoma. Melanoma is a common type of skin cancer in dogs and is the most common. It is a type of cancer that develops from the pigment-containing cells called melanocytes. This is usually found on areas of your dog's body that have hair.

Warning Signs: firm, round, raised masses that are darkly pigmented

Lymphoma. Lymphoma is a cancer of a type of blood cell (lymphocytes) and lymphoid tissues.  Lymphocytes are a type of white blood cell that helps the immune system fight off infection.

Warning Signs: swollen nymph nodes that grew 3-to-10 times their normal size

Bone Cancer. Bone cancer in dogs is also known as osteosarcoma. This refers to the most common bone tumor found in dogs. This type of cancer is extremely aggressive and has great chances of spreading fast into other parts of your dog's body.

Warning Signs: swelling of areas near the joints, joint or bone pain, lameness, and a mass growth on your dog's body

Hemangiosarcoma. This is a highly malignant cancer that can spread fast through the blood cell routes. It is usually found in your dog’s heart and spleen.

Warning Signs: inability of spleen to function, tumor of the liver that will result in liver failure

Preparing for battle

Nutritional Therapy. Cancer in dogs causes great metabolic changes in your dog's body. And providing your dog with nutritional therapy approved by your vet will keep him well-nourished and increase his immune responsiveness.

Nutritional supplements, such as fish oil, are also recommended for supplementation in pets dealing with the big C.

Find A Progressive Veterinarian. Let's admit it, there are vets that will only suggest management procedures that will earn them more. Look for a veterinarian who will explore all possible methods of treatment and will also consider your financial capacity.

Focus On Being Happy, Even Though It Is Difficult. ‘Smile though your heart is aching,' applies in this very trying time. Your dogs can sense your moods and feelings and they may think your sadness is because they've done bad things. This will add on to your dog's stress and I know you wouldn't want that.

Try to focus only on the positive side of things, remembering all the great adventures you've been through together. Live with peace and know that your pet having cancer is not defeat.

The sad thing about cancer is its causes and treatments are still unknown. Everything is uncertain, except for one thing: your goal to maintain your furry friend's overall health and nourishment, providing him the best quality of life possible even with cancer.

May is National Pet Cancer Awareness Month.
