Cancer physicians usually don't spend much time discussing nutrition with patients. However, oncology centers often have dieticians or a separate nutrition department that can help patients eat healthfully during and after treatment. The choice of foods can either assist treatment or work against it. For example, vitamins C and E should not be taken through the period that a patient receives chemotherapy because their antioxidant properties may make some treatments less effective.
The University of Alabama in Birmingham provides an example of nutrition advice available at many cancer centers. The Birmingham News reviews general guidelines for proper eating for cancer patients and recommends several books on nutrition and other resources. The writer also provides a personal account describing how healthful nutrition aided her own treatment for non-Hodgkin's lymphoma.
