Women who breastfeed have a higher risk of developing breast cancer?
Women who breastfeed have a decreased risk of developing breast cancer.
The Harvard Nurses' Study, which is one of the largest and most comprehensive studies of female health ever conducted, has found that women who say they consume three or more glasses of milk per day are 30% more likely to develop invasive breast cancer over the course of the study.
Women who are breastfeeding experience significant hormonal changes, including reduced estrogen levels. A woman's body typically produces less estrogen when they're breastfeeding which reduces cell growth and division.
Many women tend to eat more nutritious foods and follow healthier lifestyles (limit smoking and alcohol use) while breastfeeding. A healthier lifestyle overall reduces risks of many diseases including cancers.
Wanawake wanaonyonyesha wana hatari kubwa ya kupatwa na kansa ya matiti Wanawake wanaonyonyesha wanapunguza hatari ya kupatwa na kansa ya matiti. Utafiti wa Harvard Nurses 'Study, ambao ni moja ya utafiti mkubwa na wa kina zaidi wa afya ya wanawake uliofanywa, uligundua kuwa wanawake ambao wanasema wanakunywa glasi tatu au zaidi za maziwa kwa siku wana uwezekano wa 30% zaidi wa kuendeleza saratani ya matiti ya uvamizi. Wanawake wanaonyonyesha hupata mabadiliko makubwa ya homoni, kutia ndani kupungua kwa viwango vya estrojeni. Mwili wa mwanamke hutengeneza estrogen kidogo wakati wa kunyonyesha, na hivyo kupunguza ukuaji wa seli. Wanawake wengi huwa na kula vyakula vyenye lishe zaidi na kufuata mtindo wa maisha wenye afya (kupunguza uvutaji sigara na matumizi ya pombe) wakati wa kunyonyesha. Kwa ujumla, mtindo wa maisha wenye afya hupunguza hatari ya magonjwa mengi, kutia ndani kansa.
