Menopausal hormone therapy slashes low bone density risk by 69%
A retrospective analysis shows that women on menopausal hormone therapy experience a 69% lower risk of developing low bone mineral density compared with those not receiving therapy. The finding highlights hormone treatment as a potentially powerful tool for preserving skeletal health during menopause.
Why Does More Cancer Imply Less Neurodegeneration and Vice Versa?
Epidemiological studies consistently reveal an inverse relationship between cancer incidence and neurodegenerative disease risk. The trade‑off is linked to how tissue‑maintenance activities, especially stem‑cell driven cell replication, decline with age. Lower replication reduces the chance of oncogenic mutations but also hampers neuronal repair, accelerating neurodegeneration. Exceptional species such as naked mole rats demonstrate that genetic mechanisms can decouple this trade‑off, achieving both cancer resistance and sustained tissue function.
