“Certainly, it’s never optimal to have deficiencies in vitamin levels,” says radiation oncologist Russell K. Hales, M.D. of the Johns Hopkins Kimmel Cancer Center on the Johns Hopkins Bayview campus. “We try to make sure that our patients are healthy, and taking a multivitamin every day.”
However, Hales warns against lung cancer patients taking high levels of multivitamins, because it can often counteract the effectiveness of chemotherapy, and radiation.
