(Ivanhoe Newswire) -- Many breast cancer patients undergoing treatment
continue to take antioxidants, even though the consequences of taking the
supplements remain unknown, a new study found.
Six in 10 women reported using antioxidants while receiving chemotherapy,
radiation or hormone therapy for breast cancer, and about seven in 10
antioxidant users said they used high doses, which was defined as higher than
the dose contained in a Centrum multivitamin.
Antioxidant supplements include vitamin C, vitamin E, beta-carotene and
selenium, and many breast cancer patients told researchers they believe the
supplements will protect them from the side effects of treatment, help prevent
breast cancer recurrence and improve their overall health.
However, the researchers warned that the actual effects of taking antioxidants
during cancer treatment are poorly understood and previous studies have yielded
mixed results.
The study's authors said since so many breast cancer patients are using
antioxidant supplements, future studies should investigate whether antioxidants
affect treatment toxicities, treatment efficacy, cancer recurrence and survival.
