Tamoxifen, an anti-estrogen drug that was developed 30 years
ago, was believed to reduce the risk of death from breast cancer by up to 50
percent if taken for 10 years.
During this time the use of tamoxifen in patients with
cancer only held for five years and is known to reduce the risk of death up to
1/3 times, as reported by the Daily Mail (05/12).
The experiment, called Atlas observes the use of this drug
on 7,000 women with cancer who are sensitive to the hormone estrogen. Half the
participants were only used for five years, while others employ up to 10 years.
As a result, there are known differences in reduction in the
risk of death in participants who took tamoxifen for 10 years. They have a
reduced risk of death over a lot, which is up to 50 percent.
"One third of women who get breast cancer have
estrogen-sensitive disease. Research suggests that taking tamoxifen for 10
years could not only save patients' lives when they eat, but also after
diagnosis," said Dr Christina Davies, chairman of the Oxford University
study.
Martin Ledwick of Cancer Research UK said that the study
also shed light on how long cancer patients have to take tamoxifen.
