Hi @DaniJ
So sorry to hear of your situation but this website is a wealth of information and the forum is very helpful.
In terms of lumpectomy versus mastectomy , my situation was I had a large lobular tumour in my left breast that was not picked up on mammogram 18 months prior.
After MRI turned out to be 5.5cm.
My breasts were E cup and my surgeon said that a mastectomy was recommended due to the size of the tumour and I was going to just have a single with reconstruction and a.reduction in other breast with aim of C cups.
In the end I went with a double mastectomy and double reconstruction ( DIEP flap).
My understanding is lumpectomy is suggested depending on the individual circumstances of the patient ( everyone has a different situation) and the larger the tumour the harder it is the save the breast.
My surgeon also discussed with me at the first meeting ( when we didn’t know exactly how big the tumour was) lumpectomy and how sometimes it doesn’t work and a mastectomy is ultimately required in a further operation.
Its a very personal decision after weighing up all the medical advice from your team.
Take care🌺
