Staging and pre-operative exams →
Those patients requiring surgery for breast cancer may also need to receive certain exams before their treatment. The doctor will try to establish the cancer’s stage at the time of diagnosis, and this process is often referred to as “staging.”
Staging exams help doctors understand if the cancer has spread, and if so, to what areas. By staging before an operation, doctors can establish the best course of action to treat the cancer.

The four grades of breast cancer
There are 4 grades (stages) of breast cancer ranging from 0 to 4. The higher the number, the more severe the cancer. In order to establish the grade of the cancer, doctors use the staging process which helps them establish:
- The exact location of the tumour
- The size of the tumour
- Whether the cancer is invasive or not
- Whether the cancer has spread to other areas, including lymph nodes
