So pleased to find some older women here, just diagnosed

I am pleased to find some other older women on here. I am 72 (don't feel it), diagnosed a couple of weeks or so ago and had surgery last Friday. The first days until core biopsy results were an absolute blur of fear, sadness and disbelief. Once I found out that the tumour was considered quite small and that the U/S didn't pick up anything in the lymph nodes I became a bit more rational. Post op biopsy showed clear margins around tumour and DCIS and clear nodes - good news! I am Oestrogen+ Progesterone- but unfortunately HER2+ and a grade 2/3 so it looks like I don't have a hope of avoiding Chemo. I was/am dreading it but seeing posts on here saying that side effects can be handled really well has given me hope that I have a good possibility of handling it despite my age. Not looking forward to the lack of hair but I guess it will be a small price to pay for the chance to live to the ripe old age I always anticipated. I am saddened by seeing so many young women facing this rotten disease and realize I am lucky to have avoided it as long as I have so shouldn't complain too much. It is still rather unreal and it is hard to see my loved ones worrying and of course fear of the unknown manages to surface regularly but taking it one day at a time and trying to stay positive. Next step is seeing an oncologist.  I have read a lot of the posts and would like to thank all the ladies on here who have shared good advice and hope. It helps to know that I am not alone.
