What level of Ki-67 is considered high in Luminal B breast cancer?
While the search results mention that Luminal B cancers have "high levels of the protein Ki-67," they don't specify an exact percentage or threshold that defines "high."
Generally, Ki-67 is a protein that indicates how quickly cancer cells are dividing. The higher your Ki-67 level, the more aggressive your cancer tends to be. Luminal B breast cancers are characterized by elevated Ki-67 levels compared to Luminal A cancers, which contributes to their more aggressive nature.
Your pathology report should include your specific Ki-67 percentage. It's best to discuss your individual Ki-67 result with your oncology team, as they can explain what your number means for your specific situation and treatment plan. Different labs and treatment centers may use slightly different cutoff points to distinguish between high and low Ki-67 levels.
