Higher attendance was found among women who had given birth to fewer than three children (ORs ranging between 1.15 and 1.37) and had used oral contraceptives (OC) within the last decade (OR = 1.22, 95 % CI 1.07-1.38) and for a longer period (OR = 1.13, 95 % CI 1.01-1.27). A lower odds of attendance was found among post-menopausal women (OR = 0.86, 95 % CI 0.77-0.96). Age \13 at menarche, age C30 at first childbirth, age C55 at menopause, age\20 at first OC use, nulliparity, breastfeeding, and hormone replacement therapy were not associated with mammography attendance. ConclusionReproductive and hormonal risk factors for breast cancer have little effect on mammography screening attendance. This may indicate a potential for underscreening of some women at higher risk.2

Factors affecting breast cancer treatment delay in Turkey: a study from Turkish Federation of Breast Diseases Societies

“…This rate of participation is lower than that in Sweden (92%) and Denmark (79%), which are the countries with a reputation for high-quality medical documentation. 35 , 36 The presence of population-based screening programmes also decreases the incidence of diagnosis of BC at advanced stages. The rate of locally advanced BC was 5% in developed countries and 18.4% in this study.…”

Health-related lifestyle factors and mammography screening attendance in a Swedish cohort study

“…Details of the different steps of exclusion, resulting in a final sample of 11 409 individuals, are presented elsewhere (Lagerlund et al, 2013). Women who had been diagnosed with breast cancer before baseline were excluded.…”

Do breast cancer risk factors differ among those who do and do not undertake mammography screening?

“…A recent Swedish study, however, found little evidence of associations between screening attendance and reproductive histories. 14 Conversely, other lifestyle risk factors associated with lower socioeconomic position (eg. high alcohol consumption, physical inactivity, obesity) may be more prevalent among non-participants 15,16 , leading to lower breast cancer risk among screening participants.…”
