Hi Denise,

I only had surgery and radiation, but I can tell you in my case the docs were right on timing wise and the effects of radiation started about two weeks in. The worst was the last week and a half or so...and then it remains in your system, but levels off and slowly decreases.
The way I was told is that "it's 2 weeks in before you feel it and two weeks after seems you're still in it." That was pretty accurate for me.
Luck to your Mom.

Take care,
Dinah
