Hi Amanda. I had Grade 2 stage 1 Lobular ER/PR +ve tumour and sentinel lymph nodes removed in May. Margins and LNs clear, and tumour small (<2cm)so didn't need chemo. Started radiation last week and will then go on to hormone blocking therapy.
I was told by rad oncologist too about heart, and their booklets referred to other side effects eg ribs.
However, my rad oncologist told me that surgery gave me 50% cure rate, add radiation brings it to 90% then with hormones up to 98% chance of being cured.
Hope this helps
