Many patients would like more attention to be paid to complementary methods during their treatment. Scientific studies show positive effects for some of these procedures with regard to quality of life and improvement of symptoms. These include yoga, acupuncture, aromatherapy and some herbal medicines.
However, some of the procedures also entail risks. For example, there are interactions between chemotherapeutic agents and herbal medicines or dietary supplements. Ignorance in the selection of the appropriate procedures can thus become a risk factor and impair the success of the therapy.
