In males, 0.5% in the 55\u201359 age group and 4.5% in the 70\u201374 age group will develop a colorectal cancer. The corresponding values in females were 0.4% and 2.5%. The cumulative risk at age 74 varied between 7.7% (one family member affected) and 25.6% (two affected) in males, and 4.3% and 14.3% respectively in females. The risk in the 40\u201344 year age group for individuals with one first degree relative affected before 45 years of age was 0.5%, similar to that of those aged 45\u201349 with one first degree relative affected with a colorectal cancer or a large adenoma (&gt; 1 cm).<\/jats:p>\n                  <jats:p>Conclusions These results suggest that screening in the general population should start at 50 or 55. The lifetime risk is high enough (over 10%) among individuals with one affected first degree relative before age 45, or with at least two affected first degree relatives, to warrant colonoscopic screening. The data provide a basis for recommendations that relatives of these patients should enter screening programmes at age 40 to 44.<\/jats:p>","DOI":"10.1136\/jms.7.3.136","type":"journal-article","created":{"date-parts":[[2002,10,1]],"date-time":"2002-10-01T15:53:59Z","timestamp":1033487639000},"page":"136-140","source":"Crossref","is-referenced-by-count":10,"title":["Family history and risk of colorectal cancer: implications for screening programmes"],"prefix":"10.1177","volume":"7","author":[{"given":"A-M.","family":"Benhamiche-Bouvier","sequence":"first","affiliation":[{"name":"Registre Bourguignon des Cancers Digestifs (INSERM CRI 9505), Facult\u00e9 de M\u00e9decine, 7 boulevard Jeanne d'Arc, BP 87900 21079 Dijon Cedex, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Lejeune","sequence":"additional","affiliation":[{"name":"Registre Bourguignon des Cancers Digestifs (INSERM CRI 9505), Facult\u00e9 de M\u00e9decine, 7 boulevard Jeanne d'Arc, BP 87900 21079 Dijon Cedex, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J-L.","family":"Jouve","sequence":"additional","affiliation":[{"name":"Registre Bourguignon des Cancers Digestifs (INSERM CRI 9505), Facult\u00e9 de M\u00e9decine, 7 boulevard Jeanne d'Arc, BP 87900 21079 Dijon Cedex, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Manfredi","sequence":"additional","affiliation":[{"name":"Registre Bourguignon des Cancers Digestifs (INSERM CRI 9505), Facult\u00e9 de M\u00e9decine, 7 boulevard Jeanne d'Arc, BP 87900 21079 Dijon Cedex, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Bonithon-Kopp","sequence":"additional","affiliation":[{"name":"Registre Bourguignon des Cancers Digestifs (INSERM CRI 9505), Facult\u00e9 de M\u00e9decine, 7 boulevard Jeanne d'Arc, BP 87900 21079 Dijon Cedex, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Faivre","sequence":"additional","affiliation":[{"name":"Registre Bourguignon des Cancers Digestifs (INSERM CRI 9505), Facult\u00e9 de M\u00e9decine, 7 boulevard Jeanne d'Arc, BP 87900 21079 Dijon Cedex, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2000,9,1]]},"container-title":["Journal of Medical Screening"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1136\/jms.7.3.136","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1136\/jms.7.3.136","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T05:51:18Z","timestamp":1777614678000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1136\/jms.7.3.136"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000,9,1]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2000,9,1]]}},"alternative-id":["10.1136\/jms.7.3.136"],"URL":"https:\/\/doi.org\/10.1136\/jms.7.3.136","relation":{},"ISSN":["0969-1413","1475-5793"],"issn-type":[{"value":"0969-1413","type":"print"},{"value":"1475-5793","type":"electronic"}],"subject":[],"published":{"date-parts":[[2000,9,1]]}}}
