Study: Big baby link to breast can­cer

The Sunday Post (Dundee) - - NEWS -

Giv­ing birth to a big baby in­creases a woman’s risk of breast can­cer by 53%, ac­cord­ing to a new re­port.

The study could help to iden­tify women who should be of­fered pre­ven­ta­tive drugs or more fre­quent screen­ing.

Giv­ing birth pre­ma­turely also in­creases the risk of breast can­cer, the study sug­gested. The find­ings add to ev­i­dence that hor­monal and bi­o­log­i­cal changes dur­ing preg­nancy play an im­por­tant role in women’s vul­ner­a­bil­ity to the dis­ease.

Hav­ing chil­dren is known to cut a woman’s chance of breast can­cer in the long term but un­til now no ma­jor stud­ies had looked at whether the type of preg­nancy af­fected these risks.

The study did not prove a causal link but lev­els of hor­mones such as oe­stro­gen, known to in­flu­ence breast can­cer, are higher with big ba­bies.

An­thony Sw­erd­low, of the In­sti­tute of Can­cer Re­search, which led the study, said: “Preg­nancy makes a large dif­fer­ence to women’s sub­se­quent breast can­cer risk, and it seems rea­son­able that if preg­nancy af­fects risk, the type of preg­nancy might mat­ter too.”

Baroness De­lyth Mor­gan, chief ex­ec­u­tive of Breast Can­cer Now, said: “We can now go on to in­ves­ti­gate why these as­pects of preg­nancy may in­crease breast can­cer risk.”
