MORN­ING BOOST: Women who are “larks” and at their best early in the morn­ing are less likely to de­velop breast cancer than their night-owl sis­ters, a study has found. The re­searchers who com­pared data on hun­dreds of thou­sands of women found that those with an in-built morn­ing pref­er­ence were 40%-48% less at risk of breast cancer. Part of the anal­y­sis also showed that women who slept longer than the rec­om­mended seven to eight hours per night in­creased their chances of be­ing di­ag­nosed by 20% per ad­di­tional hour spent asleep. Lead sci­en­tist Dr Re­becca Rich­mond, from the Univer­sity of Bris­tol, said; “The find­ings of a pro­tec­tive ef­fect of morn­ing pref­er­ence on breast cancer risk in our study are con­sis­tent with pre­vi­ous re­search high­light­ing a role for night shift work and ex­po­sure to ‘light-at-night’ as risk fac­tors for breast cancer.” SCREEN TIME: Find­ings from the Ox­ford In­ter­net In­sti­tute at the Univer­sity of Ox­ford found that ev­ery hour school age chil­dren spent on dig­i­tal de­vices only equated to be­tween three and eight fewer min­utes of sleep each night. The re­search, ti­tled Dig­i­tal Screen Time and Pae­di­atric Sleep and pub­lished in the Jour­nal of Pe­di­atrics, found that teenagers who ab­stain from tech­nol­ogy got an aver­age of eight hours and 51 min­utes of sleep a night. How­ever, teenagers spend­ing eight hours each day on screens still man­aged an aver­age of eight hours and 21 min­utes of sleep each night. The re­searchers sug­gested that other fac­tors re­lat­ing to fam­ily and daily rou­tine pos­si­bly should be the fo­cus when try­ing to get chil­dren to sleep bet­ter. EARLY PRE­VEN­TION: Treat­ing pre-can­cer­ous stem cells at an early stage could be key to pre­vent­ing bowel cancer in peo­ple born with a very high risk of the dis­ease, a study sug­gests. Peo­ple with the con­di­tion carry a fault in a gene called ade­no­ma­tous poly­po­sis coli (APC) and have a greater than 95% chance of de­vel­op­ing bowel cancer. Sci­en­tists found that an ex­ist­ing cancer treat­ment called Cis­platin could pre­vent cancer in the mice if used at an early stage. Pre-can­cer­ous stem cells were more sen­si­tive to Cis­platin than nor­mal stem cells in the gut of the mice. The find­ings were pre­sented at the NCRI Cancer Con­fer­ence in Glas­gow.
