Try to keep a fat sack at all times to help with chemo.
Also, be sure to suck on a popsicle while you are doing your chemo treatments, this helps you not get a sore mouth. Don't know why it works, but it does.
my sister is going through this right now as well. They just removed the lump and are deciding what type of Chemo to use. So I can relate as to what she is going through. Be strong. They have made tremendous advancements in treating Breast cancer treatment. My prayers are with you
