Studies released this year by the National Cancer Institute and others have linked long-term estrogen use to breast and ovarian cancer, raising concerns among women who use the hormone.
A federal advisory panel recommended the hormone - http://www.healthynewage.com/?s=hormone be listed as a cancer agent two years ago, and the National Institute of Environmental Health Sciences made it official this week with the publication of its biennial report on carcinogens.
The report, listing substances that are known or reasonably anticipated to cause a cancer risk, was sent to Congress and released by the Department of Health and Human Services.
While the expert panel recommended that the group of hormones known as steroidal estrogens be listed as cancer risks, members observed that they have benefits as well as dangers. The substances are used in hormone replacement therapy and oral contraceptives.
The panel did not suggest banning estrogens but said officially linking them with cancer could make it more probable that physicians - https://www.change.org/search?q=physicians would discuss both risks and https://www.opblog.top/ - https://www.opblog.top/ benefits when discussing options with their patients.
The 10th annual cancer report brings to 228 the number of substances linked to cancer.
While the new report lists steroidal estrogens as "known human carcinogens," some of the individual steroidal estrogens had been listed as "reasonably anticipated carcinogens" in past editions.
Also newly listed as known causes of cancer in humans are broad-spectrum ultraviolet radiation - whether generated by the sun or by artificial sources - and wood dust.
The report, issued every two years, is required by Congress to help keep the public informed about substances or exposure circumstances that are known or are reasonably anticipated to cause human cancers. It does not determine how great the risk is or any balancing benefits from the substances.
Added to the list were of known carcinogens were:
Twelve substances or groups of substances are newly listed as "reasonably anticipated to be human carcinogens." These include:
