Welcome Sharon.
So do you have your pathology results?
There is a number of diffetent ways breast cancer is classified.
Stage...is size and mode inbolvement.
Grade is after pathology and is how closely the cancer resembles the origibal cell it came from...so it csn mean how many times it has changed from when it mutated.
I've added some usefil links and bcna have a pathology download page which will help you understsnd more about your type of breast cancer. Kath x
