@MrsMorrisey and @Jenni22 just minor correction about ribociclib and abemacuclub.
These are not chemotherapy drugs. They can have chemo like side effects but the truth is that most people tolerated them very well.
These drugs are what they call cdk4 inhibitors
https://myjourney.org.au/article/1864They are usually used for people who have metastatic disease however some studies show it is helpful for those with early breast cancer who reoccurance chance is very high. It seems using it for early breast cancer is relatively new.
I have mets and am.on ribociclib and its tolerated well. I live a reasonablely normal life. I am on other treatment. At the time of my early breast cancer these cdk4 inhibitors were not available unless it was mets. I wish they had of been.
