A very dear friend has a son who was an undercover detective for the NYPD. As the towers were collapsing on 9/11, he was there and worked there for three months. Now he has B-cell lymphoma which has been traced to that time there.
He and his partner are profiled in THE NEW YORK TIMES New Jersey Section There is a video available online, along with an article on them, www.nytimes.com/intheregion.
I know it's been hard on my friend, but she's taking it one day at a time and making the most of their time. It must be very hard knowing that there's nothing you, as a mother, can do to make everything OK again.
