A recent study demonstrates a proven way to lower breast cancer risk and occurrence by half.

Sounds too good to be true? It’s not, because a huge proportion of breast cancer cases can be traced to something women voluntarily do: take replacement hormones.

Women who took estrogen and progestin post-menopause to replace hormones doubled their risk for breast cancer. Even more dramatic, when they stopped taking hormones, their risk subsided within two years.

This is not to say that everyone taking hormones should drop them immediately. The risk increases with time, so short-term use is not likely to result in cancer.

With aging, comes reduced hormone levels. Does reversing the hormone levels reverse aging?
Not exactly, but it might come close.
Human growth hormone is a hormone that predominantly increases height. While doing so, it also increases muscle mass and bone density. HGH is at its highest levels during childhood and puberty. As we mature, the levels decrease, beginning a sharp decline at around age 30. At around that time, bone density declines, muscle mass reduces, and physical disorders like diabetes increase.
Until now, some of the more desperate aging generation have taken HGH in the hope of reversing aging, but research has not corroborated their theory.
But now, something new is in the air. According to Natalie Angier of the NY Times: “In a clinical trial of 21 healthy men ranging in age from 61 to 81, researchers found that after six months of injections of a genetically engineered version of the natural body hormone, the men emerged with bodies that by many measures were almost 20 years younger than the ones they started with.”
Aging was measured only in the distribution of body weight. The men were found to have increased muscle mass and decreased fat. The scientists hypothesize that some bulk went to internal organs, which shrink with age, but aren’t sure. The men’s skin also increased in thickness and youth, and bone density increased.
Of course, the significance of this improvement is debatable. HGH is known to increase muscles mass and reduce fat, but without really increasing strength. And what’s the point of muscle without strength? Similarly, the change in appearance was not correlated to an increase in performance of organs or body.
And as with all drugs, there were the side effects. HGH can cause swelling in the face, arms, and legs; arthritis; diabetes; hardened arteries, high blood pressure, and heart failure; and abnormal growth of bones and organs, among others.

Some news from the science front! Hormone replacement in women is linked to hip replacement -  and childbearing is linked to knee replacement. These two new findings come out of England where 1.3 million women were followed since 1996.
Hormone replacement therapy is quite common among post-menopausal women, particularly those at risk of osteoporosis. Estrogen prevents bone-loss, which in turn prevents osteoporosis. But it seems to have a negative affect on join strength. Notable, estrogen with progestragen was more closely correlated with hip replacement than estrogen alone or tibolone.
The second finding is more startling. It’s well known that running, excessive jumping, climbing, and carrying heavy things can damage the knees, but nobody ever thought to apply that to carrying children. Though, when you think about it, some of those babies can get quite heavy.
This finding creates one of those tight corners often created by conflicting medical advice. Exercise during pregnancy is highly recommended, but it’s important to avoid unduly stressing the knees. Here are a few recommendations:
1. Swimming. Swimming takes the weight off your legs while getting your heart rate pumping. An outdoor pool or swimming no more than once a week because of the chlorine and ammonia that can build up over indoor pools.
2. Rowing, weightlifting (from sitting position), and similar exercises are healthy and will also get you ready to start carrying around a 10 lb baby.
3. Biking on a stationary bike will support your weight while giving you great aerobic exercise.
4. Yoga is both relaxing and healthy and a good idea any day.
