Well-written and well-explained …  Dr. Poothullil’s reasons for addressing dietary issues are clear and compelling. … Well worth a careful reading.

— Peter C. Phillips, MD, Pediatric Oncologist


Written specifically for parents and will enhance their knowledge and provide guidance during the stressful times being experienced.  

— Cliff DeBenedetti, M.D. Pediatrician

If you are the parent of a child with cancer, the overwhelming multitude of questions, feelings, and associated anxiety are hard to contain. What caused the cancer? What can you as a parent do to help your child live through it? What is the future for your child? 

In this insightful and thoughtful book, you will find information, hope, advice, and solace. Dr. John Poothullil expertly guides you to understand childhood cancer. He starts with his two new scientific theories to explain how the leading types of childhood cancers might occur, given that children have not lived long enough to develop the number of gene mutations that usually cause adult cancers. 

You will learn how you as parents can care for your child with cancer with understanding and sensitivity, creating a loving home environment full of communal activities to reduce everyone’s stress and worry. 

Most importantly, Dr. Poothullil explains why your child’s diet can be a key corollary element in controlling cancer along with the medical treatments. You will learn how a diet low in grains and grain-flour products slows cancer cell growth, giving your child’s immune system a better chance to contain it.  

Valuable extra material in the book includes simple instructions to do gardening and cooking as calming activities to enjoy life for children with cancer. Three superbly illustrated short stories that parents can share with their child are also included.

When Your Child Has Cancer: Insights and Information to Empower Parents surveys the basic facts about childhood cancer with the purpose of “giving parents and professionals new insights into childhood cancers, particularly how and why they are occurring among more and more children.”

From how children can have cancer without gene mutations occurring to a section of three illustrated stories parents can use to talk to a young child about cancer, When Your Child Has Cancer covers many different aspects of the disease and its causes and impact.

35 years of medical practice expertise lends to this discussion of why, how, and when children come down with cancer.From insights into controlling cancer with food choices to organizing activities for the child undergoing cancer treatment, When Your Child Has Cancer blends assessments of various options with a focus on how to explain facts and handle the child in treatment.

Its wide-ranging approach elevates it beyond a singular production, offering recipes, picture book stories, medical advice, and insights on alternatives to make for an all-in-one guide for recovery. When parents face a cancer diagnosis for their child, it’s often not possible to consult multiple references to get all the information needed to handle their questions as well as address their child’s needs.

When Your Child Has Cancer resolves this problem by having everything under one cover, and should be the starting place for any parent facing a new diagnosis and cancer’s challenges.

This is an excellent book…very informative and useful. It is factually supported, eminently readable and lucidly written. Surviving Cancer provides insight and valuable advice for anyone who has been diagnosed with cancer. As an oncologist working in this field for decades, I highly recommend this book.

Surviving Cancer is my contribution to the literature on cancer and reflects my decades of study as a cancer survivor and as trained MD to think about the human body and the causes of disease, especially cancer and diabetes. In it, I present new ideas and insights into what cancer fundamentally is, how it occurs in the body, why it is so hard to “cure,” and what choices each of us individually has (and collectively as a society as well) to prevent cancer-related death. My explanations for why cancer happens are extremely important to understand, especially if you have been diagnosed with it. Your journey with me begins by understanding how cancer starts, how it survives and spreads, and how you can starve it so a single tumor or localized cancer site can be successfully treated without your unknowingly setting up the conditions that help cancer spread throughout the body. I also seek to help anyone who is a survivor of cancer, so you can better understand what you can do to live as long and as well as possible. Many cancer survivors succumb to the same or different cancer years after their first diagnosis and treatment, but it is possible to influence this outcome.

Surviving Cancer provides sound research and actionable steps that anyone can follow in order to live a longer and healthier life. Whether you’re interested in preventing cancer or stopping its spread once it has been diagnosed, John M. Poothullil’s book Surviving Cancer will be an invaluable resource.
Most people are baffled by cancer. They know it’s pervasive and a leading cause of death, yet no one can seem to agree on what causes it or how to cure it. For those who are at high risk of cancer due to genetics or environmental exposure, or for those who have already been diagnosed with the disease, this can be extremely disheartening.


Physician John M. Poothullil, who has studied cancer and diabetes for over twenty years and who fought his own battle against lymphatic cancer, encourages his audience to understand cancer like an iceberg: we generally only acknowledge the visible parts while ignoring the enormous pieces that are not as easily seen.
In his accessible, highly researched, and convincing new book, Poothullil opines that cancer grows when it is fed enough glucose. This is why cancer is pervasive among those with type 2 diabetes, who have higher than average supplies of glucose circulating through their bodies.
Backed by plenty of biological research—some of which is presented in a easy-to- understand way, though at points the book’s language becomes too technical—the book forwards the notion that the spread of cancer can be halted if cells are starved of glucose. Those who are prone to cancer or who have already been diagnosed with localized cancer should eliminate grains—the main glucose-delivering culprits—from their diet, Poothullil says.
With dietary recommendations, thoughts on exercise and supplements, stress-related information, and more, the book is a complete guide for those who want to fight against cancer.
With feet in the worlds of both nature and medicine, the book does an excellent job of not being too dogmatic. It does not decry conventional methods of cancer treatment such as chemotherapy or radiation, yet it encourages patients to be proactive about their own health by watching what they eat and drink and how they live their lives.
The book’s format is easy to navigate. It includes a helpful prologue, short and digestible chapters, and an accessible summary that provides conclusions and key points for convenient reference once the book is completed.
A must-have for those at high risk of developing the disease, Surviving Cancer provides sound research and actionable steps that anyone can follow in order to live a longer and healthier life.

Surviving Cancer: A New Perspective on Why Cancer Happens & Your Key Strategies for a Healthy Life offers several new perspectives on cancer that don’t appear in other books, despite the volume of literature produced yearly about cancer survival.
The audience most likely to gain from the book include those who have been diagnosed with localized cancers that have not yet spread and those with a family history of cancer who have not yet been diagnosed.
It also contains many points about diabetes and its link to cancer and treatment approaches; so diabetics will find much food for thought, here.


The first of these new perspectives lies in a key to understanding the science and medicine of cancer itself, fostered by Dr. Poothullil’s original thinking that since the dawn of time, cells are driven to divide. This backdrop suggests that we cannot stop cancer cells from forming –they constantly occur, but the body usually eliminates them. The remainder of the introductory section on why cancer happens thus delves into the physical properties of cancer, from abnormal and dysfunctional cell development and influences on cancer’s chemistry within the bigger picture of gene mutations. Those processes influence cancer development, the internal and external characteristics of cancer cells, and the role chronic inflammation plays in cancer’s ability to metastasize.
Part 2 presents the meat of the title and comes after explaining that cancer’s birth and progression is substantially aided by the consumption of carbohydrates from grains, producing glucose that feeds cancer cells. A surprising insight is also that the insulin the body produces to convert glucose to energy aids in producing a cancer-enriching environment. As a result, the book recommends that the way to halt cancer growth is to ‘starve’ cancer cells, by not consuming grains (“…if you have cancer, your goal should be to reduce your intake of glucose-producing grains to as close to zero as possible.”),
This approach involves adopting a diet that may actually assist diabetic diets. Dr. Poothullil also places matters in perspective when he points out that stopping cancer is a priority over controlling diabetes. This means that diabetics should try to cut down on their insulin injections and use diet to reduce their blood sugar, given that insulin promotes cancer growth.
Diet adjustments, exercise, and managing stress are not typically seen as key components of cancer-busting routines; but keep in mind that Surviving Cancer is not just about beating cancer, but promoting a healthier lifestyle overall.
Pair a new theory about the biological basis of why cancer appears and spreads which maintains that the body is constantly producing cancer cells as part of its natural process with a focus on changing the milieu which makes for a welcoming environment for cancer and you have a very different kind of cancer survival book that focuses on prevention, understanding, and an overall better approach to living.
Readers willing to make lifestyle changes to prevent, limit, and curtail cancer’s appearance and spread will find Surviving Cancer offers not just hope, but a proactive approach that places patients in charge of many different options.

This book is especially important for anyone with Type 2 diabetes, because you are twice as likely to develop certain types of cancer compared to individuals who do not have diabetes. I became familiar with this statistic because I have been researching and studying Type 2 diabetes for more than 20 years. During this time, I developed new theories and ideas to explain how high blood sugar develops and becomes Type 2 diabetes. In 2015, I published a book, Eat Chew Live to explain those concepts and teach people how to avoid Type 2 diabetes.

Along my journey to understand high blood sugar and diabetes, I became especially intrigued as to why people with high blood sugar levels have a higher incidence of cancer than people who do not have high blood sugar. In applying my knowledge about the cause of Type 2 diabetes to the biology of cancer, I learned and developed several insights that I believe help explain the link between diabetes and cancer.

So if you have diabetes and cancer, this book is extremely important to your health.
