Dads with only daughters at higher risk for prostate cancer

Men With No Sons More At Risk For Prostate Cancer ScienceDaily 1/4/07 ""We surveyed vital status and cancer incidence, and found a strong trend for a decrease in prostate cancer risk as the number of sons increased," said Susan Harlap, MD... Overall, there was a 40% increase in prostate cancer in men lacking sons...in men with exactly two offspring, those with no daughters had an 11% increase in the incidence of prostate cancer, and those with no sons had a 47% increase, compared with men who had one son and one daughter. "The increased risk of prostate cancer in men with no daughters is probably due to chance," says Dr. Harlap, "but it might indicate a problem with a gene on the X-chromosome."
