This is an internationallyrecognised system for measuring how aggressive the cancer looks under the microscope. The maximum score of various aspects of the way the cancer cells look is 8/9 out of 9. This is called Grade 3. It is associated with higher risk, but it is not the only factor taken into account when determining risk of a cancer and the necessary treatment/ options for treatment. Other risks include the size of the cancer and the spread into lymph nodes as well as the receptor status and the Ki67 index. Gene panel studies can also help with understanding risk.
