The Claim
Low-level alcohol consumption is consistently associated with an increased risk of breast cancer in premenopausal and postmenopausal women.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Even small amounts of alcohol are linked to a higher chance of developing breast cancer in women, whether they have gone through menopause or not.
See the scientific wording
Alcohol consumption, even at low levels, is consistently associated with an increased risk of breast cancer in both premenopausal and postmenopausal women, as demonstrated across multiple large prospective cohort studies.
What the research says

This study says that even a little bit of alcohol can raise the risk of breast cancer in women, no matter their age or whether they’ve gone through menopause — which matches what the claim says.
