New to this forum

I'm pretty new here - learning and lurking until now. It's heartening to hear the stories of so many women dealing with the same or similar situations. My admiration to all!
My 73rd birthday is in September. Since I've been pretty much keeping my diagnosis to myself, which is ridiculously isolating, I'm particularly encouraged to hear from so many contributors in the over-65 demographic. I've followed the traditional course of biopsy, surgery, radiation (proton) and endocrine therapy. However, I'm left in a quandary as my current Onc, who was "on the fence" re: chemo, is now telling me, weeks later, he does not support it for me. Not because it will not provide benefit (my Oncotype dx is very high) but due to age, comorbidities (I have a mild ILD and an autoimmune) and whatever other factors he has gleaned over just 2 visits. I know it can take a huge toll on an aging body, making it difficult to judge the risk/reward ratio. I'd love to hear from those who "chemoed" and what the experience was like for you. Certainly never thought I'd be advocating for Chemotherapy for myself but here we are. I want to give this my best shot, not be left with coulda/shoulda and hopefully see my very young grandbabies reach kindergarten! Onc has never spoken with my pulmonologist or done any kind of geriatric workup. He is highly regarded in the area so I'm trying to give him the benefit of the doubt but aside from a lackadaisical approach (I think he may be retiring soon) I'm just not getting the vibe he is out for my best welfare. So, today I start the hunt for a new Oncologist. Apologies for the windy reply. I've been holding thoughts in for far too long!
On another note, has anyway come across any credible information on DIM supplements, the use of Curcumin, etc.
And I'd love to hear from the gorgeous women in their 70s who have successfully (hug) made it through Chemo!
Thanks for listening, Laura
