James Van Der Beek is revealing his cancer diagnosis. The "Dawson's Creek" alum shared his cancer diagnosis with fans on Instagram on Nov. 3. "I've been dealing with this privately until now, getting treatment and dialing in my overall health with greater focus than ever before," he wrote on Instagram. "I'm in a good place and feeling strong," he added. James hasn't shared any details of his cancer treatment or the prognosis, but he did apologize to the people close to him that he couldn't tell personally. "Nothing about this process has occurred on my preferred timeline," he wrote. "But that plan had to be altered early this morning when I was informed that a tabloid was going to run with the news," he wrote.
