What happens if osteosarcoma is left untreated?
It may develop on the surface, in the outer layer or from the centre of the bone. As a tumour grows, cancer cells multiply and destroy the bone. If left untreated, primary bone cancer can spread to other parts of the body. Primary bone cancer is also known as bone sarcoma.

The vast majority of osteosarcomas are so-called "random cases", where no specific causes or predisposing risk factors can be identified. In young people, the development of the tumour appears to be in some way related to periods in life with rapid bone growth, hence the average for tumour development is 14-16 years.

How to treat bone cancer in dogs?
Others recommend limb-sparing surgery for dogs with bone cancer because of its effect on the quality of life.

Surgery does not increase the survival time, but it favors a less painful or painful free rest of life.
How long does it take for lameness to go away?
As the condition progresses, lameness tends to go from intermittent to constant over the course of 1 to 3 months. As the osteosarcoma develops, it consumes the normal bone structure, and as a result, the strong and healthy bone tissue is replaced with porous and weak cancerous bone-like tissue.
