Hi @SoldierCrab, I guess not common but possible really is the answer for them. I was TNBC and had bilaterals, really so 0% risk to unaffected side. There is no guarantee of getting every single cell of breast tissue on the affected side so always a percentage of risk remains. However, there are a lot of other prognostic factors with grade etc that influence the ongoing (or not ongoing) path of the beast. I think that like you said 'minimising risk of recurrence' is what resonates with most of us! Bec xx
PS you rock @SoldierCrab, you are so generous with your time and info and links etc for all of us - thank you! X
