Another day and more tests for my friend since I last saw her

One was a body scan which I gather was to detect any other tumors that may be hidden but in her body.

Chemotherapy every two weeks. Is this normal and how long does a course usally last?
What are the % of her having a complete recovery?

Anyone know these facts and figures or experienced them for yourself or from a close friend?
Please feel free PM me Debbie if you don't feel able to post on this open forum.
Help and advice is very much appreciated
