Hi

Sorry to hear about your mum. I was diagnosed with grade 2 bilateral breast cancer in 2018. It is quite a shock when first told but gets easier once there is a treatment plan in place.

At the breast clinic an ultrasound would have checked for spread to the lymph nodes, if found your mum would have been sent for a CT scan. I take it since your mum is meeting the surgeon first rather than an oncologist that they do not think it has spread? Therefore the surgeon will outline what surgical options are opened to your mum. Your mum will be assigned a breast cancer nurse who will support her through her decisions and her treatment.

On the day of the surgery your mum will be injected with radioactive dye which the surgeon will use to see if her lymph nodes 'react' if they do the surgeon will remove them and send to lab for testing (staging cancer). Depending on what the end post operative results are your mum will be offered relevent treatment. 

I would imagine your mum will be offered surgery quite soon. Good luck with the surgeon, always useful to go in with a preprepared list of questions as its easy to forget or railroaded. Hope this helps x
