I just read your post for the first time today and I am sending my prayers and hugs to both you and your sister.

My sister was diagnosed three years ago with breast cancer and we thought we had it licked. Last year it metastasized to her liver and was re-classified as stage four, metastatic breast cancer and her cancer changed from HER2 positive to triple negative, the most deadly type of breast cancer. She contacted MD Anderson in TX and she flew out there for no reason. They were not helpful at all and was told she was not a candidate for surgery because one of the tumors was wrapped around a major artery. She came home deflated. She discovered a program that was offering an experimental drug and she got in the lottery for the drug. That drug dissolved the tumor completely and a surgeon at UCLA did surgery to remove any remaining cells, there were none. If we have won this battle, my sister will be one of the first to survive this deadly type of cancer.

Don't give up Linda there is always something else out there and you just have to keep looking and asking. I know it is exhausting and emotionally draining. You and your sister are in my prayers. I pray that some other treatment will present itself and you and your sister and she has the energy to continue to fight. Hugs to both of you.
