Birth Control Pill Gives Long-lasting Protection Against Ovarian Cancer, Study Shows ScienceDaily (Jan. 27, 2008) ― The contraceptive Pill gives women substantial and long-lasting protection against ovarian cancer, according to a new report led by Oxford scientists published in The Lancet. The researchers found that the protection against ovarian cancer lasted for more than 30 years after women had stopped taking the Pill. They also found that the longer the Pill was used the greater the protection and that taking the Pill for 15 years halved the risk of ovarian cancer.Researchers estimated that, in high income countries, using oral contraceptives for ten years reduces the risk of developing ovarian cancer before the age of 75 from 12 down to 8 per 1000 women, and reduces the risk of death from ovarian cancer before age 75 from 7 down to 5 per 1000 women.The new report brings together worldwide evidence from 45 epidemiological studies of ovarian cancer in 21 countries. These include 23,257 women with ovarian cancer of whom 7,308 (31 per cent) had used oral contraceptives and 87,303 women without ovarian cancer of whom 32,717 (37 per cent) had used oral contraceptives.Lead author Professor Valerie Beral, director of the Cancer Research UK Epidemiology Unit at Oxford University, said: ‘Worldwide, the Pill has already prevented 200,000 women from developing cancer of the ovary and has prevented 100,000 deaths from the disease. More than 100 million women are now taking the Pill, so the number of ovarian cancers prevented will rise over the next few decades to about 30,000 per year.’The Pill also causes long-lasting protection against endometrial cancer (cancer or the lining of the womb) but causes a short-lived increase in breast cancer and in cervical cancer (cancer of the neck of the womb). Co-author Sir Richard Peto, Professor of Epidemiology at Oxford University, said: ‘Young women don’t have to worry about cancer from taking the Pill because the eventual reduction in ovarian cancer is bigger than any increase in other types of cancer caused by the Pill.’Young women take the Pill mostly for contraceptive purposes. There are known to be some definite health risks among current or recent users. But these are outweighed by the long-term protective effects against ovarian cancer ? one of the most dangerous types of cancer.The study, led by Oxford University researchers, was conducted by the Collaborative Group on Epidemiological Studies of Ovarian Cancer, a collaboration involving 120 researchers from around the world. The work was supported by Cancer Research UK and the Medical Research Council.Adapted from materials provided by University Of Oxford. -------------------------- There is no new words in this reading for me, by the way.---angelonduty

They have not found any logical relationship between the pill and the cancer. The article mentions a time range about 15 to 30 years. It is very difficult to prove whether it is correct or wrong.The article does not mention the average age of women when they stop taking the pill. What is their age 30 years after stop taking the pill? 70, 80, ...?The article also mentions the increased risk of breast cancer and cervical cancer. It concludes that the benefit of of reducing ovarian cancer outweights all other risks. But it has not mentioned how they can draw such a conclusion. Below is the direct link:http://www.ox.ac.uk/media/news_stories/2008/080125.htmlMy conclusion is that statistical study is not science. It just tells you the possibility only.My suggestion is that don't take the pill wholly for the purpose of protection from the ovarian cancer. There is a little chance it does not work.

My grandmother used to say, "Always do good to others." She was right. I do good to others (and Nature). I sense the happiness I give them, and their happiness makes me happy.回复: Today's science, yesterday's counterscience?I go along with you, LS.
