Breast Cancer Staging Grading

There may be no cancer cells in the lymph nodes in the armpit or tiny numbers of cancer cells are found. HER2 makes the cancer cells grow and divide.

In general tumors are graded as 1 2 3 or 4 depending on the amount of abnormality.

Breast cancer staging grading. Staging and grading usually happen after your breast tumor has been removed by surgery as a pathologist will need to test the tissue in a laboratory and examine it under a microscope.

The grade is used to help predict your outcome prognosis and to help figure out what treatments might work best. As a rule the lower the number the less the cancer has spread. Stage is a prognostic factor and in broad generalization low stage cancers Stages 0-II tend to have better long term outcome than high stage cancers Stages III-IV.

This information is based on AJCC Staging systems prior to 2018 which were primarily based on tumor size and lymph node status. The stages of breast cancer range from 0 to IV 0 to 4. Breast cancer stage ranges from Stage 0 pre-invasive disease to Stage IV metastatic disease.

It then ranges from stage I 1 through IV 4. Staging means how big the cancer is and whether it has spread. Grading breast cancer cells.

Early breast cancer is stage 1 or 2. High-grade breast cancer The cancer cells look fairly or very abnormal and are more likely to grow quickly. It evaluates how the cancer cells look under the microscope physical characteristics distribution to predict how fast a tumor is likely to spread.

Since the updated staging system for breast cancer now also includes estrogen receptor ER progesterone receptor PR and HER2 status the stages may be higher or lower than previous staging systems. Doctors assign the stage of the cancer by combining the T N and M classifications the tumor grade and the results of ERPR and HER2 testing.

A higher number such as stage IV means cancer has spread more. TNM was adopted by the Union for International Cancer Control UICC in the 1950s. A lower grade number 1 usually means the cancer is slower-growing and less likely to spread.

It means the cancer is larger than 5 cm has spread to tissues around the breast such as the skin muscle or ribs or has spread to a large number of lymph nodes. The cancer is contained in the breast and may or may not have spread to lymph nodes in the armpit. Many different factors are considered before doctors can confirm.
