In 2006, war correspondent and former Nightline executive producer Leroy Sievers was diagnosed with metastatic colon cancer. He writes about the challenges and triumphs of battling the disease on his blog, My Cancer, and it's proven to be a source of comfort for many other cancer survivors. At last count, more than 30,000 comments had been posted to the site.
Leroy discusses everything from the physical realities of the disease — "Your arms or your legs are missing that last little 'oomph' that will put you on your feet and up on the walker." — to the difficulty friends and family members have talking about it — "The best conversations I have these days are about something, anything else. Politics, sports, books, whatever. If cancer is not in the room for even an hour or two, that's a gift."
We'll also have a personal and candid conversation with Elizabeth Edwards about her struggle with breast cancer.
If you're a cancer survivor, tell us about your experience living with the disease.
