Coffee may lower risk of uterus cancer: Japan study

Women who drink a lot of coffee may have less risk of developing cancer of the

uterus, a Japanese study said Monday.

The study led by Japan's health ministry monitored some 54,000 women aged 40 to

69 over about 15 years, during which time 117 women developed cancer in the

womb, according to the medical team.

The researchers at Japan's National Cancer Center divided the women into four

groups by the amount of coffee they drank.

They found the group of women who drank more than three cups of coffee every

day were more than 60 percent less likely to develop uterine cancer than those

who had coffee fewer than two times a week, the study said.

"Coffee may have effects in lowering insulin levels, possibly curbing the risks

of developing womb cancer," the study said.

The medical team also studied the effects of drinking green tea, but did not

find any link to uterine cancer.

According to the US Centers for Disease Control, uterine cancer is the fourth

most common cancer in women.
