Umm ok I know a lot but i'm not a doctor lol :)
anyways, I expect it would be possible to do an assessment and then take it from there as to what is and isn't possible.
Breast cancer is a funny old thing, I mean for some people it can be as simple as a contained lump - a couple hours in the hospital tops to have the lump snipped out as a day patient and back home for tea - end of.
For others it can be a couple days in hospital, and yet others may find the lump is the "tip of the iceberg"
some people will have a tiny pucker of the skin where the lump was snipped out others will lose the whole breast.
There are simply so many things that can happen with breast cancer, it will all depend on whether it is caught very early, whether it is a contained lump or a spreading mass - it is impossible to speculate.
