Overview
Osteosarcoma is the most common bone cancer in dogs. It can affect any dog, and seems to be quite prevalent in certain breeds. The cause of bone cancer is not known, although several theories have been postulated. It occurs most often in the long bones, particularly the distal wrist or ankle, or proximal hip or shoulder bones. It can also occur in the skull, ribs, spine and pelvis .
The best defense against this horrible disease is awareness, early detection and treatment. Sadly, many dogs are diagnosed after weeks or months of lameness attributed to sprains, arthritis or other joint problems. In the early stages, routinely prescribed anti-inflammatory medications may provide some pain relief, delaying the diagnosis even further. Persistent lameness may be the only sign of bone cancer. In most cases the diagnosis can be made by x-rays, but other tests can be done in questionable cases.
There are many options once bone cancer is diagnosed. In the past several years we have seen huge progress in the treatment of this disease. Thanks to excellent research, new surgical techniques and various chemotherapy protocols have been developed. Statistically, the longest survival rates are seen with a combination of amputation and chemotherapy. Amputation provides permanent relief of the horrible pain caused by bone cancer. Giant breeds and older dogs can function well after amputation, and most dogs are fully recovered from their surgery within two to three weeks.
Not every dog is a candidate for amputation or chemotherapy. Conservative yet aggressive therapy for non-surgical candidates includes radiation therapy, the use of intravenous or oral bisphosphonates and alternative oral chemotherapy regimens. All bone cancer dogs benefit from a change in diet, reducing carbohydrates which cancer cells need to grow. Holistic medicine is a valuable part of treatment, with the addition of supplements and immune boosters that strengthen the dog’s immune system.
Cancer is a word, not a sentence. Never give up. Believe in your dog. Every day is a lifetime. There are no wrong decisions, ever. Anything is possible, you just have to believe. If you, or someone you know, has a dog with bone cancer, please visit our online support group bonecancerdogs
