A new government report says that rates for precancerous lesions decreased about 80% among younger women who were screened for cervical cancer. That’s more evidence to show the HPV vaccine is working to prevent some cancers. The estimates were published Thursday by the Centers for Disease Control and Prevention. HPV, or human papillomavirus, is very common and is spread through sex. Most HPV infections cause no symptoms and clear up without treatment. Others develop into cancer, about 37,000 cases a year. Health and Human Services Secretary Robert F. Kennedy Jr. once called the vaccine dangerous.
