Cancer is a multifactorial disease, and each patient experiences a unique pathophysiological process. Breast cancer differs significantly from kidney cancer, and this variability is seen across all types of cancer. Even two individuals with the same type of cancer may show differences in their progression and response to treatment, often influenced by other chronic conditions. Like many chronic diseases, cancer is a complex issue influenced by multiple lifestyle-related factors.
Oncology has made significant advancements in recent years, especially for those patients whose cancer is detected in the early stages. However, once cancer has spread and formed metastases, contemporary oncology often offers limited solutions. More and more people are turning to alternative therapies after conventional oncology has provided an unfavorable prognosis. Many of these therapies lack solid scientific evidence and are mainly based on the placebo effect. However, there are complementary treatments with a strong scientific foundation that can offer significant benefits alongside conventional treatments. These treatments can also be integrated into an innovative concept called 'Drug Free Oncology®️', developed by the Pruimboom Institute.
Program
This 5-day course offers in-depth learning about cancer in all its facets.
Day 1
The first day is dedicated to the evolutionary exploration of cancer in general and different types of cancer in particular.
Day 2
The knowledge from Day 1 is essential for Day 2. On this day, we address the pathophysiology and the mechanisms behind the development of cancer.
Day 3
The third day focuses on conventional treatments and their mechanisms of action. Without this knowledge, it is impossible to help the patient with complementary interventions to chemotherapy, radiotherapy, or biotherapy.
Day 4
Day 4 is the peak day: personalized treatments based on the concept of 'Drug Free Oncology', emphasizing that there are no terminal diseases, only organisms without purpose and organisms in great conflict with their environment.
Day 5
The fifth day is exceptional: the presentation of clinical cases with profound results. We do not claim to cure all cancer patients; what we do know is that there is always hope based on a mindset that activates what humans do best: an anticancer immune response.
More than 40 hours of live content + space for questions + practical integration + patient testimonies.
