폐암 조기 진단, 치료법 발견

Life-long smoker Carol Springstun is now battling lung cancer. “I’ve just been smoking since I was a teenager. But I just…. I just didn’t think it was going to happen to me.” 10-20% of smokers eventually develop lung cancer. But until now, there hasn’t been a way to predict who will get the disease. Now researchers may have found a way to tell who is at risk and the clues are not in the lung.

"This test now allows us for the first time to identify changes in the windpipe호흡기관 of smokers who’re on their way to getting lung cancer, either prior to developing the disease or at the very earliest stages of the disease where it's potentially curable. It's to me like a molecular pap smear of sorts.”

Smoking causes 9 out of 10 cases of lung cancer. Most of these are caught too late for treatment to do much good. “There is no screening test for lung cancer with the result that lung cancer is now being identified unfortunately in very advanced stages.” The researchers have already taken a first step in developing drugs to stop it before it starts. “We now can use a particular natural compound called Mio-Inositol to reverse the activity of these genes in someone who's on their way to developing lung cancer and potentially prevent the disease from happening.”

Carol says knowing who is at high risk could make a big difference. “Hopefully it would motivate more people to stop smoking.” And quit the killer habit that kills more Americans than any other cancer. Elizabeth Sanchez for CBS News, Los Angeles.

Three months ago, a St. Louis woman using a pair of adopted embryos배아 gave birth to twins. Now the donor family wants two other embryos returned, sparking a unique custody battle. CBS’s Kelly Wallace explains.

Jen McLaughlin considers 12-week-old Anna and Sarah her miracles. The 39-year-old who couldn’t have children adopted five kids, four from Russia and one from Missouri, before reading about embryo adoption. "I was like this is perfect. You now, I'll have the opportunity to be pregnant.” On a website, she located a California couple who wanted to donate four frozen embryos. In a contract signed by McLaughlin and to the California couple, the embryos were described as preborn children who are entitled to자격을 주다 the rights and protection accorded to all children legally and morally.

Two embryos were left over. Embryos McLaughlin wants to use to give birth again because she considers them Anna and Sarah's siblings형제자매. But last month, the donor mom notified McLaughlin she wanted to give the embryos to another family,

and is demanding them back today.

McLaughlin’s hired a lawyer to prove she has a legal right to keep them and expand her family. Kelly Wallace, CBS News, New York.
