[Chetry:] Welcome back to the Most News in the Morning. Twenty- eight minutes past the hour right now. We check our top stories. After dedicating themselves to getting Barack Obama in office, now gay rights groups are hoping now is finally the time that the president will take action. The White House says President Obama plans to address the nation's largest gay rights groups this weekend ahead of its planned march on Washington. Right now, the military's ban on gays in the military still stands and hundreds of troops are still being dismissed despite the president's promise to overturn it.
[Roberts:] More mixed messages from North Korea. South Korean reports says the North is now in the final stages of restoring nuclear activities. That's something that it promised to do back in April. This comes as North Korean dictator Kim Jong-il reportedly told China that he is willing to come back to the table if U.S. relations improve.
[Chetry:] And breaking news overnight. General David Petraeus says that he has undergone "successful radiation treatment for prostate cancer." What kind of battle is it for a 56-year-old military man in charge of the war in Iraq and Afghanistan? Dr. Sanjay Gupta is live with us now. So as we found out he had radiation treatments some months ago. What do we know about that treatment and how quickly his cancer was caught?
[Dr. Sanjay Gupta, Cnn Chief Medical Correspondent:] Right. What we know is he was diagnosed back in early February. And it sounds like it was diagnosed on a routine screening. At that time typically patients are offered a couple of different options or really three different options. One is to essentially do something known as watchful waiting. Just sort of keep an eye on things. Radiation therapy, which you just talked about, which there are two types. You can radiate from the outside, or you can put seeds on the inside or you can have surgery. Those are really the three options. The radiation therapy, you know, it's usually a daily or almost daily therapy over a couple of months. You know, it's something that you can have over half an hour, an hour and really go in and you can go back to work after that. Sometimes people will feel a little irritation to their bladder afterwards. They may get fatigued but that's typically some of the side effects that they have with it. Afterwards, you have to sort of monitor the same blood test to see if the cancer is potentially returning.
[Roberts:] So does he have any treatment going forward or is it all just sort of watchful waiting?
[Gupta:] Well, now that radiation is done and again they weren't specific in the statements that we've looked at as to what exactly which type of radiation he had. It's probably going to be more of a monitoring situation, John, where you have this PSA test every three to six months. Now, John, one thing that we have talked about before on AMERICAN MORNING, I think it's worth pointing out is not everyone buys into this whole idea of PSA testing. In fact, the American Cancer Society doesn't necessarily recommend it. The United States Preventative Task Force doesn't necessarily recommend it. The problem with this test, John, is that you can have the PSA test but have no idea if it's high whether that means you have an aggressive cancer or a mild cancer which may never pose a problem in your life. So this is still an area of sort of controversy and further research in medicine.
[Roberts:] All right. Sanjay Gupta for us this morning. Doc, thanks so much.
[Gupta:] Thanks, guys.
[Roberts:] Raymond Clark, the man accused in the brutal murder of Yale grad student Annie Le is back in court later on today. That case is bringing the issue of violence at work back to the front burners. So how do you know if you're safe in the workplace? Our Carol Costello is live with part two of our series "When Co-Workers Kill" and she with us in Washington this morning. Good morning, Carol.
[Carol Costello, Cnn Correspondent:] Good morning, John. 517 people were murdered at work last year. That number is actually down but an American college survey found things like bullying, harassment even physical altercations are way up. So how can you protect yourself at work? Listen to your gut.
[Costello:] We hear it often after a crime is committed. A man or woman just snaps and becomes a killer. It's a theory experts say that's rarely true especially in the workplace.
[Larry Barton, President, The American College:] I have studied literally thousands of cases of person at risk at work. About 82 percent of the time there are signals that a person is having difficulty.
[Costello:] Subtle things like an overreaction to criticism, anger directed at co-workers on blogs or in letters, obsession with people or work policy or bullying others to do things a certain way. Subtle but obvious signs that are often overlooked. In 2005, Erin Sperry, a 20 year old supervisor at a fast food restaurant was beaten to death by a co-worker. Her mother Johna Lovely says there were plenty of signs her daughter's killer exhibited obsessive bullying behavior.
[Johna Lovely, Daughter Murdered By Co Worker:] They are supervisors and complained, you know, that he rubbed up against them and it made them feel bad and I don't think really anybody took it seriously or said anything.
[Costello:] Why do you think they didn't?
[Lovely:] I don't think people are trained in doing that. I don't think they know to do that.
[Costello:] At the National Oceanic and Atmospheric Administration or NOAA near Washington, D.C., they are trying to make sure employees know how to read the signs.
[Charles Baker, Dep. Director, Noaa Satellite & Info Service:] We have a new program which is called respect.
[Costello:] The program which is just a-month-old, it specials out if a co-worker's behavior should concern you on its web site and if employees still aren't sure, NOAA has set up a hotline to complaints anonymously or to offer guidance. It's actually one of the few companies taking steps to identify potential violent employees before it's too late. According to the Bureau of Labor Statistics, in 2005 only 30 percent of employers had formal programs that addressed workplace violence. [on camera]: Why do you think more employers aren't doing something like this?
[Baker:] I think there is initially a fear on embarking on a new program and it will cost money and suck up people's time and will become a burden to the organization.
[Costello:] NOAA says its program cost very little. The hotline is manned by one of its human resources employee trained in workplace violence. And in case you're wondering, NOAA does not believe employees just snap. There are always signs. You just need to know how to read them. Again, what are those signs? They can be as simple as a co-worker doing something that makes you uncomfortable like say rearranging your desk while you're away or bullying you in a meeting. The key is this, if the behavior is an ongoing pattern, tell your supervisor. Trust your gut. If it doesn't feel right, act. It could save your life.
[Roberts:] Good advice this morning from Carol Costello. Carol, thanks so much. And tomorrow we're going to look at some things that you can do to keep yourself safe at work. Alina Cho has got the latest on our series "When Co-Workers Kill." That's tomorrow right here on the most news in the morning. Thirty-five minutes after the hour.
