My attention is drawn to this blog by Adrian Sudbury who has just made the difficult decision to stop treatment for leukaemia (two leukaemias in fact) after suffering his second relapse.
As you would expect from a journalist, it is extremely well-written. Heed his plea for bone marrow donors.
Update: As we are receiving so many hits on this post, our visitors may also be interested in these sites by Davo and Josie Grove who made the same decision and are no longer around. Both died last year.
