Stopping Femara after 5 years

Thanks everyone for the great feedback - I very much appreciate you all taking the time to help me out. A second opinion or at least an explanation of their decision is in order. My mum has pre-osteoporosis and is on vitamin D and calcium supplements as well as injections every 6 months to harden her bones. I know she gets a lot of bone pain - always resulting in numerous bone scans for fear of the cancer been in her bones. I wonder if his has something to do with their decision to stop femara? I guess they have to weigh everything up - but we don't want the cancer to return. Unfortunately my dad just got diagnosed with cancer last week. We aren't sure what treatments he is up for yet. I know mum wants to be in the best shape health wise to help him get through it... Life sucks sometimes hey! Wish cancer didn't exist .. It's great we have all these treatments now but it's so much to go through.. And watching people you love struggle & not been able to do anything. Would be great if all cancers could be prevented somehow! Then some families aren't touched by cancer at all and you wonder what we are doing wrong! Aragh! Anyway thanks again everyone & wishing every one of you good health, & optimism xx I'm going to find a second opinion for mum.
