Estrogen as a cancer causing agent

Dr. Weeks’ Comment:  Poison is always a matter of dosage and the same applies to carcinogenic agents like estrogen. The key issue is balance, hormonal balance wherein the forces of proliferative estrogen are balanced by the calming forces of progesterone.  Estrogen dominance – a condition which causes premenstrual cramps and menopausal concerns as well as cystic processes and fibroids – is easily treated. But  now we learn again (since 17 years ago) that birth control pills are carcinogenic. Bio-identical hormones are essential. Synthetic knock off near miss hormones such as progestins and horse estrogens are dangerous, albeit very profitable for big pHARMa.

Estrogen as a Carcinogen

JAMA. 2001;285(3):284. doi:10.1001/jama.285.3.284-JHA00014-4-1

Although the new classification serves as a precaution, the group did not suggest that estrogen use be restricted or banned, and expressed reservations that the designation might overshadow the hormone’s medical value. Physicians and women should weigh the known benefits of steroidal estrogens against their risks, the panel said.
