Well after lots of visits to different departments at the Plymouth Derriford hospital I finally made the decision to accept the risks and go ahead with the surgery. I really felt that I didn't have any other choice.
The date has now been set for the surgery to take place on Friday 13th August. It's a good job that I am not superstitious as the date wouldn't fill a lot of people with optimism.
On the assumption that I survive the surgery the chemotherapy for my blood and bone cancers is likely to start again in early September.
