Menopausal hormone therapy may lower risk of B-cell non-Hodgkin lymphoma

Hormone therapy, which is prescribed to women for relief of menopausal symptoms such hot flashes, night sweats and vaginal dryness, has recently seen a decline in popularity (and use) due to its link to an increased risk of breast and endometrial cancer. But City of Hope researchers have found that menopausal hormone therapy may actually lower the risk of B-cell non-Hodgkin lymphoma. [More]
