Studies & Trials in the New Millennium
The largest ever prostate cancer prevention trial, Selenium and Vitamin E Cancer Prevention Trial (SELECT) is launched to determine whether these two dietary supplements can protect against prostate cancer.
NCI launches the National Lung Screening Trial (NLST) to determine whether spiral computed tomography is better than single-view chest x-ray in reducing deaths among current and heavy smokers.
Results from the Prostate Cancer Prevention Trial (PCPT) show that men taking finasteride had 25 percent few diagnoses of prostate cancer than men taking a placebo, proving that prostate cancer can be prevented.
Two randomized controlled trials show that taking aspirin daily for as little as 3 years reduces the development of colorectal polyps by 19 to 35 percent in high risk populations.
The Women’s Health Initiative (WHI) shows that women who take estrogen in combination with the hormone progestin are at greater risk of developing breast cancer than estrogen alone.

Initial results from the Digital vs Film Mammographic Imaging Screening Trial (DMIST) show that women with dense breasts under the age of 50 who are pre- or post-menopausal may benefit from a digital rather than a film mammogram.
