Younger Age at Menopause Tied to Higher Risk for Bladder Cancer

An earlier age at menopause is associated with a higher hazard for bladder cancer, consistent with a look at presented at the annual assembly of the European Association of Urology, held from March 15 to 19 in Barcelona, Spain.

Mohammad Abufaraj, M.D., from the Medical University of Vienna, and co-workers investigated the impact of hormonal and reproductive elements on bladder most cancers danger using information from 106,138 girl registered nurses collaborating in the Nurses’ Health Study (NHS) and 113,974 who participated in NHSII.

During a follow-up length of up to 36 years, researchers observed 441 incident bladder most cancers cases. In the NHS, 21.3 percent of girls have been menopausal at baseline as opposed to 2.4 percent inside the NHSII. Younger age at menopause (≤45) changed into related to an increased chance for bladder cancer (multivariable-adjusted incidence risk ratio [IRR], 1.41; Ptrend = 0.01), particularly among ever smokers (IRR, 1.53; Pinteraction = 0.16) compared with ladies taking part in NHS with menopause onset at ≥50 years. There changed into no affiliation between bladder most cancers hazard and age at menarche, parity, age in the beginning birth, oral contraceptive use, or postmenopausal hormone use.

“The capability protective effect of longer reproductive years on bladder most cancers hazard adds new proof to our expertise of sexual dimorphism in bladder most cancers,” the authors write.
