As many as 8 million adult women in the U.S. who should be screened for cervical cancer haven't had that checkup in the past five years, putting them at risk for a deadly cancer that can be cured, or even prevented, if found early, federal health official said Wednesday, NBC News reported. More than half of women diagnosed with cervical cancer had never or rarely been screened, the Centers for Disease Control and Prevention said. "We must increase our efforts to make sure that all women understand the importance of getting screened for cervical cancer," said the CDC’s deputy director, Ileana Arias. "No woman should die from cervical cancer."
