american college of obgyn is still to start at the age of 40. if you look at a study that came out of cancer in september showed 70% of the women they followed for over ten years diagnosed with breast cancer, 70% of the women who died, did not have screening mammograms, and the majority of the women who died were diagnosed in their 40s. and to tell a woman that she shouldn t get screened during her 40s if she doesn t have any risk factors is misleading, because 70% of the patients diagnosed with breast cancer have no family history of breast cancer. so i m afraid we re going to lose those lives of those women who feel like they are safe and they don t need to get a mammogram. mammography does save lives, and it does save lives of women in their 40s. thank you so much for joining us. we appreciate it. coming up, it s already legal in colorado and washington, now a third state could legalize marijuana for recreational use and it s getting support from an unlikely
coast of chile. loud sirens blared throughout the night, warning people of the possible coming up tsunamis. joining me now from los angeles is nbc s mark potter. mark, what are the latest details that we re getting in, regarding the assessment of damage and, of course, the fatalities? that assessment is under way now, and one thing i want to tell you, tamron, based on our time in chile four years ago when the big earthquake and tsunami hit, i can tell you nothing terrifies the chileans more than an offshore earthquake and tsunami warning. when they are told to evacuate now, they do not need to be told twice, and that s what happened last night. hundreds of thousands took to the hills to get out of the low country. fortunately this time the tsunami was not nearly as big as it was in 2010. the waves, six to seven feet high, and fortuitously, they hit in the northern part of the country in relatively remote areas in a copper mining country, so that kept the death toll down.
