Low-Dose Drug Cuts Breast Density up to 26% with Fewer Side Effects
A Karolinska Institutet study found that low‑dose endoxifen, the active metabolite of tamoxifen, reduces mammographic breast density by up to 26%—comparable to the 18.5% reduction seen with standard 20 mg tamoxifen—while causing far fewer serious side effects. In a randomized, placebo‑controlled trial, 240 healthy premenopausal women took either 1 mg or 2 mg of endoxifen daily for six months, with the higher dose achieving a 26% drop and the lower dose a 19% drop. The 1 mg regimen showed a safety profile similar to placebo, whereas the 2 mg dose modestly increased hot‑flashes. The trial is a proof‑of‑concept, indicating biological activity but not yet confirming cancer‑risk reduction.
