Here’s the breakdown of the backstage pass:
- T for Tumor Size: This is like checking out how big the rockstar (tumor) is. Size matters in the world of breast cancer stages.
- N for Nearby Lymph Nodes: Now, this part tells us if the rockstar’s entourage (cancer) has spread to nearby lymph nodes. Are they hitting the road with the band?
- M for More Distant Lymph Nodes or Other Organs: Imagine M for “More places to rock.” It checks if the cancer has spread to distant lymph nodes or other organs, turning it into a real tour.
But wait, there’s more! In 2018, they jazzed up the system to include cool factors called biomarkers. These are like the rockstar’s special skills:
- Hormone Receptor and HER2 Status: Are they rocking the hormone vibes or going all HER2 on the stage? It’s like knowing the rockstar’s unique sound.
- Grade of the Cancer: Think of it as judging the rockstar’s appearance compared to typical rockstar material. Is it a headliner or an opening act?

- Cancers that may have been assigned a lower stage may now be assigned a more advanced stage if biomarkers indicate that the cancer could grow and spread more rapidly.
Due to the complexity of the factors affecting staging, this article will largely focus on the TNM aspects of staging.

What is the prognosis for patients with breast cancer at various stages?
The NCI’s SEER database monitors cancer rates and survival data, but it takes a different approach to classifying outlooks compared to the previously mentioned stages. Instead, cancer stages in the SEER database fall into three distinct categories:
- Localized: The cancer remains confined within the breast.
- Regional: The cancer has extended to nearby lymph nodes and tissues.
- Distant: The cancer has spread to more remote tissues such as the bones or lungs.
Survival statistics are often presented as five-year survival rates, representing the estimated percentage of individuals with a specific type and stage of cancer who are still alive five years post-diagnosis. As per the SEER database, the 5-year survival rates for breast cancer are as follows.
