Hi
Warm welcome to the Mac Community, not that anyone would willingly want to join this particular club.
So sorry to see you have been diagnosed with this on top of breast cancer - has either Cervical or Ovarian been confirmed, surely you don't have both :-/
Another thing is have they arranged a BRCA Gene test for you as these cancer types do have links to eachother ?
There is a very active Breast Group here you could join if you are still undergoing BC treatment and there are also groups for Cervical Cancer and Ovarian Cancer you could join - Just click / tap the coloured text links to open the group pages.
Hope this is of some help to get you started with getting some support and questions answered, you must be wondering what you have done to get your own personal black cloud 
Take care, G n' J
