No standardization process exists to ensure that the producers of herbal remedies maintain consistency in the source and amount of the ingredients used. For example, evidence suggests that ginseng and some soy products appear to increase the growth rate of breast cancer tumors that are estrogen-receptor positive. The FDA has also issued a recent warning about St. John's Wort because it appears to interfere with a long list of prescription medications, including some cancer chemotherapies. Cancer patients who want to play a more active role in their treatment may be likely to use herbs purchased at the local health food store. No matter what the product might claim, herbs should not be expected to cure or slow the growth of the cancer, according to Martinez.
Open communication is a key element of the doctor-patient relationship.
When both doctor and patient have all the information they need, they are able to make the best and most appropriate decisions regarding treatment. It is the health provider's responsibility to ask the patient about herb use and to create an environment in which patients feel comfortable talking about their health and lifestyle. While doctors and other health professionals concentrate on providing the latest and best cancer treatments, cancer patients can participate in their own care in a number of ways. Martinez recommends examining one's diet. Incorporate good nutritional habits into your lifestyle.
