WTC Emergency Responders Have Higher Cancer Rate: Study

The cancer rate among World Trade Center emergency responders is 15 percent higher than in the general population, a new study finds.

The analysis of data from nearly 21,000 people in the WTC Health Program from 2001 to 2008 found 575 cases of cancer, compared with the 499 normally expected to occur in that number of people, the New York Daily Newsreported.

The increased risk of cancer among the 9/11 emergency responders was seen primarily in thyroid, prostate and blood cancers, according to the researchers at Mount Sinai Hospital's World Trade Center Health Program. The study was published online Tuesday in the journal Environmental Health Perspectives.

"Just seven years after the attack, our study has shown an increase in cancer even at this early stage," Dr. Jacqueline Moline, one of the study's authors, told the Daily News. She noted that cancers associated with toxic materials at the World Trade Center site take many years to develop.

"The fact that we are seeing early increases in many types of cancers makes it all the more critical for us to be vigilant in our medical surveillance of anyone who had WTC exposure and to provide treatment for them if necessary," Moline said.


All Boston Bombing Wounded Expected to Survive: Doctors

All the wounded survivors of the Boston Marathon bombings are expected to survive, according to doctors.

More than 180 people were injured in the blasts a week ago, and at least 14 of them lost all or part of a limb. Of the 51 who remained hospitalized on Monday, three are listed as critical and five are in serious condition, the Associated Pressreported.

The transit system police officer who nearly bled to death in a shootout with the bombing suspects is also in critical condition, but doctors say he is expected to recover.

Three people died at the scene of the blasts, as did an MIT police officer who was shot by the suspects, the APreported.


Alzheimer's Ends Glen Campbell's Touring Career

Musician Glen Campbell, who turned 77 on Monday, can no longer tour because his Alzheimer's disease has progressed too far, his wife Kim says.

Continued touring was something Campbell's family and management left open after he completed his successful goodbye world tour last year, but that is no longer a possibility.

However, Campbell is still healthy and continues to play golf and his family sometimes invites musicians to the house, the Associated Pressreported.

A new album, called "See You There," is scheduled to be released July 30 and features a reimagining of some of Campbell's most famous songs. It was recorded in 2011.

Campbell is spending his birthday in Washington, D.C. as an advocate for Alzheimer's research. His trip will include a fundraising dinner for the Alzheimer's Association and a visit to the Senate, the APreported.
