Hi im new to this site and very new to the word Cancer.

my 72 year old mum has just been diagnosed with ductal and lobule breast cancer mix and it has already spread to her lynyh nodes under her arm. The consultant said the lump in her breast is 2.5 cm in size.

she has to have a bone xray, ct scan and 6 months of chemo. 

I really dont know what to say or feel at the mo. Can anyone advise me on if the mix is unsual, or how do we find out what grade this is, and why haven't she been offered a mastectomy , the consultant seemed like he only gave us information if we asked the question. 

Any advise would be good
