How Long Can A Dog Survive Untreated Sarcoma?

What is the life expectancy of a dog diagnosed with cancer when no treatment is administered? When cancer in dogs goes untreated, the typical survival period is two months or less. However, the prognosis varies significantly when treatment is provided, contingent on the cancer’s stage. Dogs with low-grade oral melanoma, which includes stages 1 through 3, can extend their life expectancy to more than 18 months with proper treatment. Conversely, dogs diagnosed with high-grade melanoma, specifically stage 4, usually have a life expectancy of less than three months. This information is current as of February 7, 2023.

When it comes to dogs diagnosed with high-grade sarcomas, the outlook for their long-term health is less optimistic. In these cases, veterinarians often recommend chemotherapy to slow down the progression of metastasis, but it’s important to note that the prognosis remains uncertain. On average, dogs with high-grade sarcomas typically survive for around one year after diagnosis. Therefore, it’s crucial to take action promptly when a soft tissue sarcoma is initially detected. Early intervention offers the best chance for effective treatment and a more favorable outcome for your furry companion.

What are the consequences of leaving sarcoma untreated? When sarcoma is not promptly addressed, the unchecked division of cells leads to the progressive enlargement of the sarcoma within soft tissues. As the sarcoma grows, it forms a lump that exerts pressure on adjacent bodily tissues and organs. Additionally, there is a risk of sarcoma cells detaching from the primary site and potentially spreading to other areas of the body, a process known as metastasis. This uncontrolled growth and potential for metastasis underscore the importance of early detection and treatment of sarcoma to prevent further complications and ensure better outcomes for patients.
