Whether intentional weight loss might reduce this excess risk is not yet proven. We searched the medical literature for studies reporting changes in cancer risk following intentional weight loss, and for studies reporting changes in cancer\u2010relevant risk factors of oestrogens, sex hormone binding globulin (SHBG), Insulin\u2010like growth factor\u2010I (IGF\u2010I), IGF binding proteins and selected inflammatory markers [C\u2010reactive protein (CRP), interleukin 6 (IL\u20106) and tumour necrosis factor\u2010\n                    <jats:italic>\u03b1<\/jats:italic>\n                    (TNF\u2010\n                    <jats:italic>\u03b1<\/jats:italic>\n                    )]. Observational cohort studies and randomized controlled trials of both dietary interventions and bariatric surgery all indicate fairly immediate reductions in cancer incidence following intentional weight loss. Oestrogen levels drop and SHBG levels increase coincident with intentional weight loss, with about a one\u2010third reduction in free oestradiol to be expected from a 10% weight loss. CRP levels also drop substantially after weight loss at about this same 3 : 1 ratio. Reductions in TNF\u2010\n                    <jats:italic>\u03b1<\/jats:italic>\n                    and IL\u20106 are consistently seen, but of a smaller magnitude, and IGF\u2010I and IGFBP changes after weight loss are small and inconsistent. Because both cancer incidence and levels of circulating cancer biomarkers drop fairly rapidly following weight loss, intentional weight loss may well lead to meaningful reductions in cancer risk with a short latency time.\n                  <\/jats:p>","DOI":"10.1111\/j.1463-1326.2011.01464.x","type":"journal-article","created":{"date-parts":[[2011,7,6]],"date-time":"2011-07-06T09:47:30Z","timestamp":1309945650000},"page":"1063-1072","source":"Crossref","is-referenced-by-count":143,"title":["Does intentional weight loss reduce cancer risk?"],"prefix":"10.1111","volume":"13","author":[{"given":"T.","family":"Byers","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.
