Is hormone replacement linked to breast cancer?; Sunlight and dementia

Is hormone replacement linked to breast cancer?
Despite a link between breast cancer and hormone replacement therapy, 57 million prescriptions for HRT (Hormone Replacement Therapy) are filled each year in the U.S..

The current belief is that low-dose formulas for short periods of time are safe, but the latest research shows even short-term hormones may be risky. Many women’s symptoms of menopause now gone thanks to Estradiol low-dose hormone therapy, but are they worth a risk?

New findings from the Fred Hutchinson Cancer Research Center show HRT can increase the risk of lobular breast cancer four-fold in as little as three years. That’s earlier than the five-year period cited by past research.

Lobular breast cancer—known as "sneaky breast cancer"—is hard to detect, often diagnosed in advanced stages, and is hormone-positive.

Breast oncologist John Link, M.D., says, "We, as a profession, may have gotten women somewhat addicted to estrogen rather than letting them go through the natural process of withdrawal."

Doctor Link says women with serious symptoms should consider the lowest dose possible for the shortest time. Then get off slowly. "If you kind of just shut the door,” he says, “it really exacerbates and makes the symptoms worse."

This study is one of the largest to focus on the relationship between combined HRT and lobular breast cancer, which accounts for up to fifteen-percent of breast cancers.

Sunlight and dementia
Can a little sunshine help the elderly improve their brain power??

Doctors have found that using bright lights improves the circadian rhythm in older patients, cutting out some symptoms of dementia.

The circadian rhythm is a person's inner time clock.

It regulates mood, behavior, sleep and daily activities. It's also light sensitive.

Researchers found bright light improved thinking skills, reduced symptoms of depression and increased brain function better then traditional memory loss medication.
