Chemotherapy

I have had a video consultation with the Oncology consultant this morning.  I have grade 2 breast cancer and have to make the difficult decision about chemo.  I have been booked in for radiotherapy 15th may thought this may be enough to cope with.  I am also on Letrozole and will be having regular mammograms.  The side effects of chemo seem very severe and as I am quite active and well at the present time I am  feeling very upset by it all.

I have been reading up and trying to take in all the information I can.   I am 69yrs old quite fit and not overweight as I go to slimming classes and own a dog which gets me out and about and go on lots of holidays.

Any advice would be welcome
