Hi @Agent14516 a very tough time for you- maybe you’ve made your decision by now.
I ended up having breast conserving surgery (lumpectomy) and I was comfortable with that recommendation from my breast surgeon who weighed up various risk factors.
I had chemotherapy prior to surgery and my tumour responded (shrank). I also had radiation therapy.
On reflection I would ask your surgeon if you have invasive lobular cancer or invasive ductal cancer. I didn’t know much about ILC when weighing up my options. I think I would ask now because from my limited understanding ILC can be a bit trickier to see in future tests for recurrence and for some people it may be peace of mind for those with ILC to opt for mastectomy. Having said that I believe there are specialised mammograms (which I have had) that are more sensitive and can help with future monitoring and tests. Just a thought. All the very best.
