Hi ya ...

Breast cancer like all cancers are slightly different ... some stay contained ... some spread, they are metastasis ... and are called secondary cancer ... some times there is a completely new cancer starts and that's a second primary one ...

But yes it is possible though rare to go into other boob ... but I'm no expert or even medically trained ... so I'm hoping I've got this right ... the best thing you can do is, write all your questions down, and I'm sure your mum has some too ... and when you take her to next appointment ... you'll have them all down .. and take a pen and paper with you to right the answers down .. as believe me, half goes over our heads ... if you don't understand an answer, tell them to make it simpler to understand .. don't worry about being a bother, as it's your mum's health ... 

You sound like an amazing daughter... she must be very proud of you ... and you know there's lots of us breast lasses on here .... it has come a long way ... l had a grade 3 ... and masectomy in 2017 ... and my son and daughter in law and my amazing nieces ... that's what gets us through ... sending you a vertual hug ... Chrissie x  here's to kicking cancers butt ...  ; ))

Hi,

I had cancer in both breasts and each was a different cancer, both are treated individually i.e. two primaries so not a case of spreading from one to the other. I would be surprised if you mother’s cancer had spread from one breast to the other, not that it really matters, cancer is cancer regardless and your mother will be treated accordingly.

Hi have a look on the site there are quite a few ladies who have a similar problem get talking to them it will help. Good luck.
