| February 2001 What is the difference between 230 in 100,000 and 350 in 100,000? An increase of 120 or about 52% Combined with other cases of cancer, the study concluded that there's a 70% increase... It's a "70% increase" ... But 3.5 in 1000 is less than a half of one percent. See the medical story below. What is the risk of being killed while driving or riding in a car? http://tti.tamu.edu/ The link to the Texas Transportation Institute Lots of data about transportation In 1999: 41,717 people lost their lives on our streets and highways, 1.6 deaths per 100 million vehicle miles of travel. A typical person travels 25,000 miles by car per year. 4 years 100,000 miles 40 years 1 million miles 4000 years - 100 million miles�. 1.6 deaths in 4000 years 1 death every 2400 years. 2400 years of driving before you will die in a car? (based on miles driven) ====================================== What portion of the population drives or rides in a car each year? 250 million passengers and drivers in the USA (out of a population of 280 million) 40,000 deaths / 250 million == 40/ 250,000 or 16 deaths in 100,000 passengers and drivers So getting breast cancer is less likely than getting killed in a car� Hmmmm ------------------------------------ Women who use hormone supplements are 70% more likely to develop breast cancer. By LINDSEY TANNER, AP Medical Writer CHICAGO (February 13, 2002 9:38 p.m. EST) - A new study adds to the growing body of evidence that recent, long-term use of hormone supplements following menopause may increase the risk of breast cancer. Women who had taken estrogen alone or estrogen plus progestin for at least five of the preceding six years were about 70 percent more likely than nonusers to develop breast cancer, the study found. The increased risk was about 50 percent for developing ductal cancer - which occurs in the milk ducts - and about threefold for developing lobular tumors, which form in the milk-producing glands and account for about 10 percent of all breast cancer cases. The study further complicates the complex question of whether to take hormones after menopause. Estrogen supplements are taken by millions of women to ease hot flashes, brittle bones, and other symptoms of menopause. ..... The findings suggest that nonusers of hormones have an annual incidence of ductal cancer of about 230 per 100,000 women, compared with 349 ductal cases per 100,000 women with recent hormone use of five years or more. Lobular cancer would develop among nonusers in 23 per 100,000 women a year and in 70 per 100,000 women who have had five or more years of recent hormone use. Only 91 of the 705 study participants with breast cancer developed the lobular kind, and just 17 of the lobular group were long-term recent users of hormone supplements. .... Most women who take hormones do so for less than five years, said Dr. Eric Bieber, chairman of obstetrics and gynecology at Geisinger Health Systems in Danville, Pa. Bieber questioned the study results based on the scant data. "I don't think it's a settled issue," he said. 16 deaths in 100,000 by car 3.7 incidents of breast cancer in 100,000 --------------------------------------------------------------------------------- Conclusion: You're 4 times more likely to be killed in a car than get breast cancer, even if you are taking hormone replacements. ------------------------------------------------------------------------------------- Highways Third Annual Forum on Public Health and Transportation Safety Tremendous progress was made in the United States in the 20th Century in reducing the rate at which people were killed and injured on our streets and highways. In 1969, for example, some 53,543 motor vehicle fatalities were recorded in the United States, 5.0 fatalities per 100 million vehicle miles of travel. Thirty years later, in 1999, some 41,717 people lost their lives on our streets and highways, 1.6 deaths per 100 million vehicle miles of travel. No discipline has a monopoly in the fight to reduce motor vehicle deaths and injuries in this country. Engineers, educators, law enforcement officers, social scientists and the medical and public health communities all have roles to play. The Third Annual Forum on Public Health and Transportation Safety will be held at the Hornberger Conference Center in Houston on March 12-13, 2002. This Forum provides opportunity for professionals drawn from different disciplines to discuss and learn more about transportation-related deaths and injuries. http://tti.tamu.edu/ The link to the Texas Transportation Institute Lots of data about transportation References Population: http://www.dayof6billion.org/home.htm Population clock at US Census Bureau http://www.census.gov/cgi-bin/popclock |
