TNBC is known for being fast-growing and has a higher chance of spreading or coming back after treatment. This generally means that survival rates are lower compared to other types of breast cancer. However, survival rates are estimates based on previous cases and do not predict individual outcomes. Here’s a breakdown of 5-year relative survival rates:
- Localized (cancer has not spread outside the breast): 91 percent
- Regional (cancer has spread to nearby structures or lymph nodes): 66 percent
- Distant (cancer has spread to distant parts of the body): 12 percent
- All stages combined: 77 percent
