You may hear your doctor talk about the grade of your cancer. Tumour grade describes a tumour in terms of how abnormal the tumour cells are when compared to normal cells. It also describes how abnormal the tissues look under a microscope.
The grade gives your doctor some idea of how the cancer might behave. A low-grade cancer is likely to grow more slowly and be less likely to spread than a high-grade one.
Some types of cancer have their own grading systems but generally, there are 3 grades:
Grade 1 – the cancer cells look very similar to normal cells and are growing slowly
Grade 2 – the cells don’t look like normal cells and are growing more quickly than normal
Grade 3 – the cancer cells look very abnormal and are growing quickly
