Hi everyone just a silly question but I see often a lot of you mention Ki and then a number or percentage following. What does this mean. Thanks in advance. Hope you are all having a great long wee...

The following information on ki-67 I found on the internet. I have paraphrased some of it.
"Ki-67 is a protein in cells that increases as they prepare to divide into new cells. A staining process can measure the percentage of tumor cells that are positive for Ki-67. The more positive cells there are, the more quickly they are dividing and forming new cells. In breast cancer, a result of less than 10% is considered low, 10-20% borderline, and high if more than 20
Ki-67 is a cancer antigen (protein) found in growing, dividing cells but is absent in the resting phase of cell growth (when cells are not growing). The fact that Ki-67 is found in dividing cells makes it a good proliferation marker (since cancer cells rapidly grow and divide) to follow the progress of breast cancer.
When it comes to breast cancer, the Ki-67 test may be performed on a sample of breast cancer tissue to help predict the aggressiveness of the cancer. The test, performed by a pathologist, measures the level of Ki-67 expression in the cancer cells through a staining process."
