What is Ki67?

Hi Abby
Thec stage relates to tumour size and where it has spread to.  Grade relates to how abnormal the cells look under the microscope ie how different compared to normal cells.  The Ki67 relates to how fast the cells are replicating ie how quick the tumour is growing. Search the BCNA website under pathology.  There's a good basic explanation of tumour pathology. 

Hi @Abbydog
My breast cancer surgeon explained 
grade 1 is better than grade 2
stage 1is better than stage 2
low ki67 is better than high ki67

He said if you imagine low ki67 is a choirboy and high ki67 is a bikie.
But not all choirboys are good and not all bikies are bad.😊

Take care 🌺

Thanks for your replies.
julez1958 I like the choir boy and bikie analogy .

@Julez1958 yet another example of the doctors not really knowing 🤷‍♀️
