The severity level of cancer; the higher the grade, the lower the prognosis in many cases. It’s important to continue your cancer journey regardless of the determined grade. Every dog is different and will respond differently to treatment.

Grades of Cancer

There are several different grades of cancer. The grade of a cancer helps determine how serious it is and how it should be treated.

Here’s a breakdown:

  • Grade 1: The tumor is small and not very invasive. It may still be able to spread, but it’s not likely.
  • Grade 2: The tumor has extended into the surrounding tissue, but hasn’t grown deeply into the surrounding tissue or organs yet.
  • Grade 3: The tumor has grown deeply into the surrounding tissue and possibly even into other organs nearby, but hasn’t spread outside of your body yet.
  • Grade 4: This is the most serious type of cancer; it has spread to other parts of your body and may be hard to treat or slow down if left untreated.
