publish my diary log

During my breast cancer diagnosis (diagnosed Aug 2010), surgery and treatment I kept a diary log of the ‘journey’. I have had it self published through lulu.com (all 40,000 words), however I have kept my profile private so only I can order copies. A few people have read my book and said I should think about publication. I would really like to do this and have all the proceeds going to Breast Cancer Research. I would really appreciate if anyone has done this, or if anyone can advise me of how I could go about it. I really want to be able to ‘give something back’ after all the care and treatment I have recieved and much of it due to the ongoing research undertaken to improve survival for people with the devestating diagnosis of breast cancer. Can anyone help me? J.
