TL;DR: Calcium supplementation is associated with a significant - though moderate - reduction in the risk of recurrent colorectal adenomas, independent of initial dietary fat and calcium intake.

TL;DR: A multicenter, population-based, case-control study with a sample large enough for it to describe more precisely the association between lactation and the risk of breast cancer.

TL;DR: Treatment with beta carotene does not reduce the occurrence of new skin cancers over a five-year period of treatment and observation and there was no significant difference between treated and control groups in the mean number of new nonmelanoma skin cancers per patient-year.

TL;DR: The hypothesis that aspirin has an antineoplastic effect in the large bowel is supported and the question of whether aspirin should be used to prevent large-bowel tumors would be best answered by a randomized controlled clinical trial specifically designed to address this issue.

TL;DR: There has been a marked rise in the incidence rates of BCC and SCC skin cancers in NH in recent years, and the anatomic pattern of increase is consistent with an effect of greater sunlight exposure.
