What is the significance of a Ki-67 score of 89?
A Ki-67 score of 89% indicates that a high proportion of your tumor cells are dividing and growing. This number describes what percentage of cancer cells are actively multiplying at any given time.
A Ki-67 of 89% is considered high, which typically means:
- The cancer is more aggressive and fast-growing
- The cells are dividing rapidly
- The tumor may be more difficult to treat
Generally, the lower the Ki-67 proliferation index, the less aggressive the cancer tends to be. Your oncologist will use this information along with other factors from your pathology report to determine the best treatment approach for your specific situation.
It's important to discuss what this means for your individual treatment plan with your medical team, as they can explain how this fits into your overall diagnosis and care strategy.
