Breast cancers diagnosed shortly after pregnancy may be biologically more aggressive
A study from UCLA Health suggests that breast cancers diagnosed within three years of childbirth may be biologically more aggressive than those in women who have never given birth. Researchers are working to define this postpartum window to improve early detection and treatment outcomes.
Why it matters
Understanding the biological risks associated with the postpartum period could lead to more tailored screening and treatment protocols for younger women.
Research reveals a critical biological window for breast cancer risk after pregnancy.
Breast cancers diagnosed during the first 3 years after childbirth, particularly within the first year, may be biologically more aggressive than similar cancers in women who have never given birth, according to a new study led by investigators at the UCLA Health Jonsson Comprehensive Cancer Centre .
The findings, published in the journal npj Breast Cancer , add to growing evidence that postpartum breast cancer may represent a distinct form of the disease and suggest the period of greatest biological risk may occur earlier than previously thought.
