Cancer deaths drop, prostate cancer diagnoses spark concerns

Cancer deaths in the United States have dropped 33% the past three decades, according to a report from the American Cancer Society. Cervical cancer rates dropped 65% for women in their early 20s, but there are troubling signs as well. Advanced prostate cancer diagnoses have risen roughly 4.5% annually since 2011. Karen Knudsen of the American Cancer Society joined Amna Nawaz to discuss the study.
