As a very long term cancer survivor, I found this book very disturbing.Dr Priestman is, it is stated,a very senior radiologist, yet with this book, he puts lives at risk. The total assurance of the safety of modern radiotherapy does the reader no favours-few cancer treatments are benign, understandably, and radiotherapy can increase health risks, but may well dramatically prolong your lifespan or quality of life.The reader should be alerted to the fact that side effects may arise in decades to come, some of which could be serious, but lifestyle changes could play a major part in reducing risks.Being forewarned of possible risks to look out for is forearmed-giving bland reassurances of total safety is highly questionable and does ring alarm bells coming from such a senior figure in the medical establishment. We will not know the absolute safety of present radiotherapy doses for many years, but they have of course been substantially reduced, or the treatment stopped being given to certain groups,for very specific reasons.
For anyone who has already read the book, try to do your own research -for many there may be no late effects at all, but others should be aware there may be vigilance needed,they may need to seek out specialists for guidance and help, and changing habits may help.
I understand few would question the word of such a senior figure, but when you have lived with a body treated with radiotherapy over 50 years ago for cancer, then I think you have that right. Radiotherapy can be amazingly successful, but the patient has to be their own health advocate, and this book does not help that process.
