Both my BS and oncologist have been comfortable about addressing the quality of life issues versus the benefits of taking the AI for the full length of time prescribed.
I'm comfortable with and acknowledge that medical care is not perfect but the best available we have now. Ultimately it's our body, our life, and we have the right to say no. I have a friend in her 40s who has Stage 4 bowel cancer. As well as chemotherapy she has pursued a considerable number of alternative therapies. Now, with her tumour markers well down, and against her oncologist's advice, she has decided to stop the chemo. Only time will tell what happens, but it's her right, her body, her life and as much as I disagree with it, I respect her decision.
Take care, K xo
