BACKGROUND Dietary supplements are widely used by cancer survivors. However, health effects among older cancer survivors are unclear. METHODS We used the Iowa Women's Health Study, a prospective cohort study with 2,118 postmenopausal women with a confirmed cancer diagnosis (1986-2002), to evaluate the association between postdiagnosis dietary supplement use assessed in 2004 and subsequent all...

BACKGROUND/OBJECTIVES Ultraviolet B (UVB) irradiation on skin can induce production of reactive oxygen species (ROS), which cause expression of matrix metalloproteinases (MMPs) and collagen degradation. Thus, chronic exposure of skin to UVB irradiation leads to histological changes consistent with aging, such as wrinkling, abnormal pigmentation, and loss of elasticity. We investigated the prote...

This interdiction persists, in spite of high rates of dietary supplement use by patients throughout all phases of cancer care, and can result in patients' perceptions of physicians as negative, thus leading to widespread nondisclosure of use. A review of the clin...

In the present study, we aimed to describe dietary changes made post-diagnosis and current dietary supplement use by survivors of colorectal cancer (CRC), and explore the underlying motives for these lifestyle habits. Cross-sectional analyses were performed for 1458 stage I-IV CRC survivors of the Patient Reported Outcomes Following Initial Treatment and Long-Term Evaluation of Survivorship (PR...
