The Ki-67 proliferation index measures how quickly cancer cells are dividing. While a lower Ki-67 index typically indicates less aggressive cancer, having a higher number doesn't mean treatment won't be effective.

The Ki-67 proliferation index measures how quickly cancer cells are dividing. While a lower Ki-67 index typically indicates less aggressive cancer, having a higher number doesn't mean treatment won't be effective. Your medical team has already taken this information into account when designing your treatment plan.

Remember that Ki-67 is just one of many factors doctors consider alongside hormone receptor status, HER2 status, tumor grade, and other markers to determine the best treatment approach. It's encouraging that you're almost done with chemotherapy. Chemotherapy is specifically designed to target rapidly dividing cells, which is exactly what a high Ki-67 indicates. The fact that you're nearly finished with your treatment plan means you're taking all the right steps to fight your cancer.

If you're concerned, bring up these questions at your next appointment. Your oncologist can explain how your specific treatment plan was chosen to address your individual case, including factors like your Ki-67 number.
