Breast cancer risk by age at birth, time since birth and time intervals between births: exploring interaction effects

Association of Parity and Time since Last Birth with Breast Cancer Prognosis by Intrinsic Subtype.

BACKGROUND Parity and time since last birth influence breast cancer risk and vary by intrinsic tumor subtype, but the independent effects of these factors on prognosis have received limited attention. METHODS Study participants were 1,140 invasive breast cancer patients from phases I and II of the population-based Carolina Breast Cancer Study, with tissue blocks available for subtyping using ...

The effects of twins, parity and age at first birth on cancer risk in Swedish women.

The effect of reproductive history on the risk of cervical, colorectal and thyroid cancers and melanoma has been explored but the results to date are inconsistent. We aimed to examine in a record-linkage cohort study the risk of developing these cancers, as well as breast, ovarian and endometrial cancers, among mothers who had given birth to twins compared with those who had only singleton preg...

Relationship between age maximum height is attained, age at menarche, and age at first full-term birth and breast cancer risk.

Several pubertal and reproductive events are well established risk factors for breast cancer. Age maximum height attained is an understudied potential breast cancer risk factor that may affect risk through mechanisms different from those of other pubertal and reproductive events. We assessed the relationships between different pubertal/reproductive events and risk of different types of breast c...
