My heart certainly goes out to you, knowing what you have been through and now are going through.
I'm sorry I can't give you any information on hormone therapy for cancer. Bridget, follow your instincts. You said you would rather spend what money is left on pain meds for mom and I believe you are absolutey right. With a diagnosis of Alzheimer's and now cancer throughout, I believe the most loving thing you can do is to try to keep her comfortable and pain free. Have you contacted Hospice? Again, I don't have experience with Hospice, but from what I've read here at the posts, they can be extremely helpful and do administer pain meds. Dear Bridget, I will keep you in my prayers,
