Study scope/scale

The International Consortium of Mammographic Density (ICMD) is co-ordinated by the International Agency for Research on Cancer (IARC). In ICMD, we pooled individual-level MD and epidemiologic data from studies of breast cancer-free women worldwide. ICMD includes 11755 women from 27 studies across 22 countries.

Key outtakes

  • “Mammographic density (MD) is a quantitative trait, measurable in all women, and is among the strongest markers of breast cancer risk.”
  • “Since Wolfe’s first studies linking mammographic parenchymal patterns to breast cancer (BC) risk in 1976, breast density – typically measured on a mammogram as mammographic density (MD) – is now recognized as one of the strongest risk factors for this malignancy.”
  • “Several observations suggest that MD is on a causal pathway for BC, including that tumours arise within localised areas of dense tissue, MD and BC have a partially shared genetic basis, the effects of several BC risk factors have concordant effects on MD, and some may be mediated through MD.”
  • “The International Consortium of Mammographic Density (ICMD) is co-ordinated by the International Agency for Research on Cancer (IARC).”
