Breast cancer risk is 55-100% higher in oestrogen-progestogen HRT (combined HRT) current users versus never users, cohort studies have shown.[3,4] Breast cancer risk is also higher in oestrogen-only HRT users, though to a lesser extent than with combined HRT, cohort studies have shown.[3,5-9] Breast cancer risk is not associated with past HRT use 5 years or longer ago, cohort studies have shown.[3,10] Breast cancer risk among current HRT users increases with duration of use, and with lower body mass index (BMI).[3,5,10] Breast cancer risk among HRT users may vary with previous use of OCs, but evidence remains unclear.[11-13] Breast cancer risk does not appear to be increased by use of phytoestrogens (plant-derived chemicals used by some women as an alternative to HRT), a meta-analysis showed;[14] however the efficacy of phytoestrogens for relieving menopausal symptoms remains unclear.[15] See IARC's classifications on the role of this risk factor Find out more about the definitions and evidence for this data Learn how attributable risk is calculated View our health information on HRT and cancer Hereditary factors explain only around a quarter of breast cancer risk.[1] Breast cancer risk is not associated with breast cancer in an adoptive parent, and does not vary with time since the family member was diagnosed, indicating genetic/biological factors or increased diagnostic activity rather than environmental factors underpin familial clustering of breast cancer cases.[2,3] Breast cancer risk is around twice higher in women with one first-degree relative with breast cancer, versus women with no first-degree relatives with the disease, meta- and pooled-analyses have shown.[4,5] The risk is higher still with a larger number of affected first-degree relatives, or relatives affected aged under 50.[4,5] ER-positive or ER-negative breast cancer risk are associated to a similar extent with family history.[6] Over 85% of women with a first-degree relative with breast cancer will never develop breast cancer themselves.[4] 87% of women with breast cancer have no first-degree relatives with the disease.[4] BRCA1 and BRCA2 mutations confer a high risk of breast cancer in carriers (high-penetrance).

Breast cancer risk increases by 3% for each year older a woman is when she first gives birth, a meta-analysis showed.[1] The association may be limited to ER/PR-positive tumours.[2-4] ER/PR-positive breast cancer risk is 15% higher in women who first gave birth at an older age, compared with those who did so at a younger age, a meta-analysis showed.[4] HER2-positive and triple-negative breast cancers are not associated with age at first birth.[4] Conversely among BRCA1 mutation carriers, breast cancer risk may be lower in those who are older at first birth, meta-analyses have shown;[5,6] among BRCA2 carriers, breast cancer risk is not associated with age at first birth.[5,6] Breast cancer risk increases by 5% for each year younger at menarche (first menstrual period), a meta-analysis has shown.[7] The association is stronger for oestrogen receptor (ER)-positive and progesterone receptor (PR)-positive tumours than for ER- and PR-negative tumours.[2] Breast cancer risk may be higher in women whose breast development started at a younger age, a cohort study indicates.[8] Among BRCA1 mutation carriers too, breast cancer risk may be higher in those who are younger at menarche, a meta-analysis showed; among BRCA2 carriers, breast cancer risk is not associated with age at menarche.[5,6] Breast cancer risk increases by around 3% for each year older at menopause, a meta-analysis has shown.[7] Post-menopausal women (natural menopause or induced by surgery) have a lower risk of breast cancer than pre-menopausal women of the same age and childbearing pattern, a meta-analysis showed.[7] Reproductive organ surgery Breast cancer risk is not associated with tubal sterilisation, a meta-analysis showed.[9] Breast cancer risk is 24-41% lower in women who have hysterectomy and oophorectomy before menopause, compared with women who do not have these surgeries, a pooled analysis and case-control study showed.[10,11] Hysterectomy and oophorectomy after menopause may be associated with increased breast cancer risk if oestrogen therapy is used after the surgery, a pooled analysis showed.[10] Breast cancer risk decreases by 7% with each live birth, meta-analyses have shown.[1,2] Breast cancer risk may not be associated with twin pregnancy, a meta-analysis showed.[12] ER/PR-positive breast cancer risk is 25% lower in women who have had children compared with those who have not, a meta-analysis showed.[4] HER2-positive and triple-negative breast cancer is not associated with parity.[4] The association between parity and breast cancer may vary by tumour types, with the largest risk reduction for mucinous tumours, and a risk increase for medullary tumours, a cohort study indicates.[13] Conversely among BRCA1/2 mutation carriers, breast cancer risk is not associated with parity, one meta-analysis showed,[5] though another showed a decreased risk with higher parity.[6] International Agency for Research on Cancer (IARC) classifies the role of this risk factor in cancer development.[1] An estimated 1% of female breast cancers in the UK are linked to oral contraceptives (OCs); because breast cancer risk is generally low in the OC-using population (typically younger women), OC-related risk contributes a relatively small number of additional cases.[2] OCs contain synthetic sex hormones, which may explain the link between OC use and breast cancer risk.

Current users of OCs have around 24% higher breast cancer risk compared to never users, a meta-analysis showed.[3] However, breast cancers in OC users tend to be less advanced compared with those in OC never-users.[3] The relative risk of breast cancer declines after OC cessation, such that 10 years after cessation no excess risk remains.[3,4] Breast cancer risk does not appear to increase with longer duration of OC use,[3,4] however, younger age at first OC use is associated with a larger increase in breast cancer risk.[3] The risk associated with OC use appears to be similar across OC formulations (which have changed considerably over time), family history, BRCA carrier status (though some evidence of no association with OC use in BRCA1/2 mutation carriers), and ethnicity.[3,5,6] See IARC's classifications on the role of this risk factor Find out more about the definitions and evidence for this data Learn how attributable risk is calculated View our health information on hormones and cancer International Agency for Research on Cancer (IARC) classifies the role of this risk factor in cancer development.[1] Hormone replacement therapy (HRT) contains synthetic sex hormones, which may explain the link between HRT use and breast cancer risk.

This largely reflects cell DNA damage accumulating over time.

Damage can result from biological processes or from exposure to risk factors.
