Dear Readers: First of all, I want to say I want to prevent cancer recurrence. Recurrence means cancer coming back. I survived a Desmond tumor 15 years ago. A Desmond tumor is a very low grade sarcoma, only 10% chance to recur. I know with the lifestyle adjustments in this book I learned and do, the chance of recurrence is probably zero. Recurrence, or cancer coming back is fatal in this disease, as I read in Memorial Sloan-Kettering Cancer Center literature. The next thing I want to mention is, the price you pay for this book is the cost of printing this book. I just rounded off the pennies of the cost figure provided by the publisher, to make it a lucky number. The number .38 means being alive and thriving. I am a physician specialing in cancer treatment. That is: I am an ocologist. For the last 10 years before my retirement. I "preached" lifestyle interventions to my cancer patients, in addition to them receiving standard treatments. I hoped to treat them better. I did not have much expectations in life-style-change ended up controlling cancer in the beginning. Why, simply, cancer is a hell lot of a disease. You don't expect little things like exercise, which is one of the seven life-style interventions, could do much against this devilish disease, isn't it? But to my big surprise, patients with bad cancers that were expected to survive abut 1 or 2 year. Instead, they survived 3, 5, and 7 years. And it was most of them! I was exhilarated. Patients and families were happy. They were smiling. Can you imagine a person with "terminal" cancer, or their family, smiling genuinely? But, after all, a few more years is a few more years. My once sad oncologist life was turned into an acceptable one. I thrived and got the highest rating. Thanks. MY oncologist life used to be a sad one. For more than 30 years I was sad all the time inside, but now I am a happy oncologist. I would love to work till the day I die. But there was something more important. There was another calling. All the cancer patients in the world may not have known this cancer-fighting weapon they can pick up and work miracles. In the web world one can access Google or others, and find millions of ways to fight cancer, as one can read. What is the real thing? As a cancer survivor and a cancer specialist, I know. My patients' case- histories assured me of what really can beat cancer. So I reluctantly retired, though it was already beyond my retirement age - just to write books to help prevent cancer recurrence. I was reluctant, for I loved my cancer patients, and enjoyed treating them. But I have to do it. This is a higher calling. If you hesitate to believe that simple lifestyle interventions could help you prevent a good cancer from coming back, I understand. Good cancer coming back? Yes. Good cancers do come back, given time. Though the chance is small. Even stage zero breast cancers can come back by 20% or 30% chance. Stage zero here is ductal breast cancer in situ. No recurrence! Unbelievable. But I searched my memory hard, I really don't remember even a single case of a good breast cancer that ever recurred. It does not seem real. Could it be I am getting senile? No, that is what the impression I have. I am smiling on this fond memory. Moderate amount of exercise is one of the 7 lifestyle interventions I emphasized in this book. How powerful is it? Two major studies showed it prevented cancer by 40-60%. It also prevented cancer recurrence. Hail to these two big studies from major US universities. They have costed more than two hundred million dollars. It is worth every single penny. There are other similar studies showing the same percentage caner prevention for different cancers, just doing simple exercise like walking. There are studies from all over the world confirming that. With this said. I hope you would benefit from it. God bless.
