Hi it is all a lot to take in but there is a certain extent to which you have to trust your medical team.
My own story was that I had a large (5.5cm) lobular tumour in my left breast which had not spread to my lymph nodes and it was ER positive, grade 2.
I was recommended radiotherapy because of the size of the tumour but not chemotherapy and I took the advice.
I decided in the end to have a double mastectomy and DIEP flap reconstruction.
There is a wealth of information on this website and no question on this forum is too silly , we have all been there in one way or another.
when you get through the surgery ( or even before if you have time) have a listen to the Dr Charlotte Tottman podcasts I found them really helpful for the psychosocial aspects of breast cancer.
I am now 12 months post diagnosis and 3 months post the DIEP surgery and getting more back to my “old self “ ( although I will never actually be that person again) every day, so there is light at the end of the tunnel!
