About the Founder

Paul Leendertse is the Pioneer and Author of 'The Root Cause of Cancer'. He has over 15 years of rare experience helping individuals overcome significant health challenges - often stage 3 or 4 cancer. 

By living with individuals with Cancer for 3 weeks at a time, over a 10 year period, examining life-challenges, traumas, and lifestyle factors, Paul discovered the root cause of cancer and how to reverse it. The Root Cause is a psycho-emotional stress complex, effecting the physical body, which needs to be identified and resolved to heal.

In his online coaching, Paul often gets to the root cause of his clients cancer in one coaching session, and begins resolving it with them. Many times clients experience significant improvement of symptoms in their first session, and full reversal of cancer through Pauls Mentorship Program.

Paul now teaches the Root Cause of Cancer to the world via his online courses. To acquire advanced knowledge and skill in the Prevention & Reversal of Cancer, including Pauls 15-step Real Self Emotional Healing Process, sign up for Cancer Prevention Coach.

Paul's Story

"In 2010 my step father who was like a father to me died of lung cancer. He died in my arms.

 I was a holistic lifestyle coach at that time, and he was receptive to my advice. He tried a variety of approaches I suggested: organic food, juicing, supplements, meditation and more. He also worked with Naturopaths using alternative approaches to combatting cancer. Additionally, he tried traditional treatments: radiation and surgery. 

Nothing was working.

Although many of these approaches had minor positive effects (the traditional ones had obvious negative effects too), over time, I watched my step dad worsen. When he died, I realized that what I knew about health was not enough.

From that moment on I devoted my life to discovering the Root Cause of Cancer. I could not learn much from books, because what I needed to know was not yet discovered. I could not learn much from science and research because the majority of research is conducted on cancer cells in a lab, not  individuals in real life.

 I did real research with real people; my clients, devoted to self-healing were my teachers. Over 10 years of working with cancer patients in personal settings, I came to understand the root cause of cancer - it is repressed and unprocessed emotional stress or pain that is held inside a person's body.

I learned not only the Root Cause, but further, the specific cause of cancer in each region of the body. It was revealed to me over and over again, from different clients with the same cancer who had similar life stresses. 

 It is because of my clients, and their honest desire and commitment to looking deeper into self-healing that this knowledge can now reach the world."
