Do Your Boobs Age Faster Than You?
Women who have noticed a slight downward trend with their breasts as they age should blame their biological clock.
Researchers from the University of California, Los Angeles have discovered that healthy breasts are about two or three years older than the rest of the body.
While the study lends to the misogynist idea that women become less desirable as they age, the findings potentially explain the prevalence of breast cancer as women get older. Nature sucks.
"If a woman has breast cancer, the healthy tissue next to the tumor is an average of 12 years older than the rest of her body," Steve Horvath, lead researcher and professor of genetics at the University of California, told Science Daily.
For the study, published in the journal Genome Biology, researchers analyzed nearly 8,000 samples of both healthy and cancerous human tissue in a range of men and women, from the unborn up to age 101. They found that tissue around tumors were an average of 36 years older than the rest of the body, which may explain why age is a major risk factor for many cancers in both genders. Horvath and his team also found that a person's heart is biologically their youngest organ, about nine years younger than the rest of their body.
Horvath invented a "clock" which measured the degree of methylation, a natural process by which DNA are altered over time. He said the "clock" correctly identifies the age of human organs, tissues and cell types.
The silver lining is that if we could miraculously find a way to reverse the aging of tissue, we could prevent diseases such as cancer. "My goal in inventing this clock is to help scientists improve their understanding of what speeds up and slows down the human aging process," he said.
