If you are worried about hair loss after you have had a mastectomy, or you have been diagnosed with hyperandrogenism, then you should reconsider taking estrogen.
It is the most common hormone replacement treatment for women over the age of 50, and estrogen is commonly used for both menopausal symptoms and hair loss.
But a study published in the Archives of Internal Medicine this week found that estrogen could lead to more severe hair loss than a placebo, and that estrogen-based treatments are associated with increased risk of cancer, heart disease, and suicide.
The study, published online in the journal JAMA Internal Medicine, looked at 8,000 people who had a total of 2,500 mastectomies over a three-year period.
They found that people taking estrogen had a 40 percent higher risk of developing cancer than those taking a placebo.
People who had an average of one mastectomy had a 39 percent higher cancer risk than those who had no mastectomy.
People with a history of cancer had a 25 percent higher chance of developing breast cancer.
People taking estrogen also had a 46 percent higher rate of developing type 2 diabetes.
This is particularly worrying because it suggests that estrogen is a possible carcinogen.
There are a number of reasons why this may be the case.
First, estrogen has been found to increase the risk of cancers in women who have already had breast cancer and other cancers, but in the study, there was no evidence of an association between estrogen use and these other cancers.
Second, estrogen-containing medications can be extremely expensive, which may make them more expensive than a pill that is only prescribed to women who need it most.
In other words, if you do not want to take a pill with estrogen, or if you are concerned about the cancer risks, it is important to find out if your treatment will increase your risk.
Finally, the study also found that patients taking estrogen-only medications had a higher risk for developing a heart attack, stroke, and other cardiovascular events.
Although the study found that there was an increased risk for cancer in people taking hormone replacement therapies, it did not say whether this increased risk was linked to estrogen or to a different hormone.
What’s more, the researchers did not include people who were taking any other medications.
“There is a lot of uncertainty around the role of estrogen in hair loss,” said Dr. David Gorski, a professor of medicine at Harvard Medical School and a co-author of the study.
“I would like to know what the relationship is between estrogen and hair growth.”
“I’m a fan of hormone replacement, because of the way it’s done, but I don’t want to make an irreversible decision,” said Karen Sargent, a hairstylist in the San Francisco Bay Area who is also an advocate for the safety of estrogen-free and hormone-free treatments.
While the study does not definitively link estrogen to hair loss in the general population, Dr. Gorski said, he hopes it will help doctors decide which hormones to prescribe to their patients.
According to the American Academy of Dermatology, estrogen and other hormones, including estrogen-replacement drugs, can cause cancer, increase the chance of heart disease and other health problems, and lead to serious side effects.
If you are considering taking estrogen, ask your doctor about your symptoms, and consult your doctor before making a decision.
