The use of hair dyes is widespread. It’s estimated that more than a third of women over age 18 and 10 percent of men over age 40 – a group that numbers in the millions in the U.S. alone – color their hair. Even if exposure to hair dye increases cancer risk only slightly, the effect on public health could be significant. We turned to the National Cancer Institute (NCI) to investigate.
When Angelina Jolie underwent a preventative double mastectomy earlier this year, this issue of cancer risk and genetics made front-page headlines. Jolie, who announced the operation in a New York Times op-ed, tested positive for the BRCA1 gene mutation and learned she had an 87 percent risk of developing breast cancer.

By Robert Haddad, MD Human papillomavirus, or HPV, vaccinations were originally advised only for girls. The Centers for Disease Control and Prevention (CDC) and the American College of Pediatrics now recommend that both girls and boys be vaccinated. The recommendations are well founded: HPV infection is the number one cause of oropharyngeal cancer, which occurs in the middle part of the throat and is diagnosed in about 14,000 Americans each year. Men are three times more likely than women to develop oropharyngeal cancers linked to HPV.

By Eric Schuller If you recently learned you have cancer, donating a sample of your cancer tissue to science is probably the last thing on your mind. But it’s a topic that you might discuss with someone on your health care team, because cancer researchers often rely on donated tissue samples to help them better understand what causes cancer and which treatments are most effective.
Actress Angelina Jolie is no stranger to the headlines, but she stunned the world with her Op-Ed in The New York Times, in which she shared her very private decision to have a preventive double mastectomy after testing positive for the BRCA1 gene mutation. “I hope that other women can benefit from my experience,” wrote Jolie. “Cancer is still a word that strikes fear into people’s hearts, producing a deep sense of powerlessness.” But for Jolie, and many others, getting genetic testing and taking action may offer control and comfort. How do you know if genetic testing is right for you? …
by Richard Saltus Colonoscopy exams get a bad rap. Even though the exam is brief and painless, many people fear and avoid them. Roughly 40 percent of Americans for whom they are recommended are not getting colonoscopies. Yet colonoscopy is one of the most effective of all cancer prevention methods. The American Cancer Society estimates there will be 142,820 diagnoses of colorectal cancer in 2013 and 50,830 people will die of the disease. As many as 60 percent of colon cancer deaths could be prevented if everyone 50 years old or above underwent colonoscopies, according to the Centers for Disease …
