Dear Docs and friends of medical science,

Tea 'reduces ovarian cancer risk' http://news.bbc.co.uk/1/hi/health/4521964.stm



The risk of developing ovarian cancer can be reduced by drinking tea, a team of
Swedish researchers says.

Karolinska Institute researchers found drinking at least two cups a day cut the
risk by nearly 50%. Antioxidants in tea are thought to be the reason. The team
quizzed over 60,000 women, 301 of whom developed ovarian cancer. The Archives of
Internal Medicine study said more research was needed, and UK experts added
there was still no proof of the benefits. Previous research has shown tea helps
to protect against several types of cancer, and boosts memory.

But the Swedish study is the first to specifically examine the relationship
between tea consumption and ovarian cancer risk. Each year about 6,900 women in
the UK are diagnosed with ovarian cancer, with more than 4,600 deaths annually.
Ovarian cancer is also the fourth most common cause of cancer death in women in
the UK. Researchers questioned 61,057 women aged 40 to 76 about their eating and
drinking habits between 1987 and 1990. The women were followed up until December
2004 to see if they got cancer. The research revealed that 68% of women reported
drinking tea - mainly black tea - at least once a month. During the study a
total of 301 women were diagnosed with ovarian cancer.

Cups

Researchers said they saw a 46% lower risk of ovarian cancer in women who drank
two or more cups of tea per day compared with those who did not drink tea. Women
who drank one cup of tea a day had a 24% reduced risk, while those having less
than one cup had 18% less risk. Lead researcher Susanna Larsson said they had
found no link between coffee consumption and the risk of ovarian cancer, but
added more research was needed.

"In summary, our results from a large population-based cohort of Swedish women
suggest that tea consumption may lower the risk of ovarian cancer. "Because
prospective data on this relationship are scarce, our findings need confirmation
by future studies." Professor Tim Key, professor of epidemiology at Cancer
Research UK, said: "The risk for ovarian cancer is strongly related to hormonal
factors - risk decreases with each child a women has, and risk also decreases
the longer women take the oral contraceptive pill. "As yet there is no clear
evidence that diet affects the risk for this cancer, and although these new
results sound interesting they do not provide firm evidence that tea drinking
has any effect on the risk for ovarian cancer."
