A new study suggests that Depo-Provera can reduce the risk of breast cancer by up to 25 percent in women who use it for contraception.
The new study, published in theBritish Medical Journal, showed that women who took the drug for three months had a 15 percent increased risk of developing a second or third breast cancer.
The risk of developing breast cancer increases with long-term use.
In the analysis, researchers found that the risk was increased by 15 percent for women who had used Depo-Provera every three months for five years or longer, while the rate was still 15 percent higher for those who took the drug every three months for seven years or longer.
The study was published in the, in March, and the drug has already been linked to a 10 percent increased risk of breast cancer in women who used the drug for three months or more.
A second study that included over 3,000 women and showed that the drug reduces the risk of developing breast cancer by up to 25 percent, the drug’s manufacturer, Pfizer, said in a statement.
The women who took the drug had a five-fold increase in risk of developing breast cancer, which is the most common type of cancer diagnosed in women. It is also the third most common type of cancer in women in the United States, and is the most common cause of preventable death.
“This is an important result that is important because it’s the first data we have on the effect of long-term use of this drug on breast cancer risk,” Dr. Susan E. White, an epidemiologist at the University of California, San Diego School of Medicine and professor of endocrinology at the University of California, San Diego, told ABC News.
The results of the new analysis were presented today at the annual Scientific Sessions in the U. S. If they are true, they suggest that the risks of developing breast cancer in women who use Depo-Provera may be far higher than they otherwise would be. That would increase the risk of developing a third or fourth breast cancer, which is the most common type of cancer.
Depo-Provera is a contraceptive method that has been shown to reduce the risk of breast cancer by about 25 percent. That’s about the same as the risk of breast cancer for other hormonal birth control methods such as the pill, implant, intrauterine device and condom.
The new study was funded by Pfizer, which sells the contraceptive drug. Pfizer said the study found no significant differences in the risk of developing breast cancer between women who used Depo-Provera and those who didn’t. The women who took the drug had a five-fold increase in risk, according to the study.
The study is the latest effort by Pfizer to investigate the connection between long-term use of contraceptives and breast cancer. The study was led by Dr. Elizabeth Doherty, a epidemiologist at the University of Oxford who is a past president of the American College of Obstetricians and Gynecologists.
Dr. Doherty said she was concerned about the study because it was the first to examine the effect of hormonal birth control on breast cancer risk.
“The study was designed to look at the effect of hormonal birth control on breast cancer risk,” she said in a statement. “This was an important study because it would provide an important insight into the link between hormonal birth control and breast cancer risk.”
But Dr. Robert H. Bixen, a professor of medicine at Harvard Medical School and a member of the Women’s Health Initiative and the American College of Obstetricians and Gynecologists, said that the new study is the first to link hormonal birth control to breast cancer risk.
He added: “The association of hormonal birth control with breast cancer risk was observed in women who took the drug for three months or more. The study is the first to link hormonal birth control with a reduction in the risk of developing breast cancer.”
The results should spur more research into the connection between long-term use of contraceptives and the development of breast cancer.
The study was published online inThe New England Journal of Medicine, in May.
Elizabeth Doherty, who is also the study’s lead author, said: “This study is the latest effort by Pfizer to investigate the connection between long-term use of contraceptives and breast cancer.

Depo-Provera, a hormone contraceptive injection, is given every three months to prevent pregnancy.
This medicine is the most widely used hormone contraceptive, used to prevent pregnancy for over 30 years.
Depo-Provera is a synthetic progestin that contains a progestin hormone. This medicine may be given to women who cannot take other hormones, like menopause symptoms, as a shot that can cause irregular periods.
The progestin is injected subcutaneously into a woman’s vagina, and it works to prevent pregnancy by stopping ovulation.
After this injection, the woman is capable of having children. Depo-Provera is given every three months to prevent pregnancy, but it is not available as a regular contraceptive pill.
Women should never use Depo-Provera.
If you are planning to become pregnant, talk to your doctor about alternative contraception or a different contraceptive method.
There are a number of other alternatives to Depo-Provera, including birth control pills, injectable contraception and birth control injection.
If you are considering using Depo-Provera, you should talk to your doctor or pharmacist about alternative birth control methods or birth control pills.
