More and more doctors and patients are recognizing that better progress in cancer treatment can be achieved by combining conventional and natural therapies into an integrative cancer treatment approach. Expertly, Dr. Andrea Flemmer has researched all the important natural therapies that cancer patients can use as complementary options to mobilize their self-healing powers and strengthen their immune system against malignant cancer cells. A diet rich in vegetables, fruits, and whole grains is the most effective way to boost the immune system. Unprocessed foods provide numerous bioactive substances, particularly secondary plant compounds, which can disrupt cancer development at various stages. In addition to a natural diet, there are other natural options that can help defeat cancer or make its side effects more bearable.
