I went through similar a decade ago (non-Hodgkin). The treatment was awful, the result satisfactory. I got the all clear in the 2nd week of Wimbledon and celebrated with a day out watching veteran's doubles on Court 3. One of my most enjoyable days at the Championships.My friend is going through this now it's awful. Wishing Francesca all the best.
Francesca is younger and fitter than me so should do well.
