Breast milk may harbor cancer clues

Analysis could provide noninvasive means for testing risk in women

ORLANDO, Fla. — Breast milk may provide a storehouse of genetic data indicating whether a woman is at risk of breast cancer, a new study finds. The findings were reported April 4 at a meeting of the American Association for Cancer Research.

Past studies of breast tissues and fluids have suggested that molecular changes in certain genes can show up in women at heightened risk of breast cancer.
