CHARLOTTE, N.C. — It’s a big week at the pool in Charlotte as Olympic swimmers hit the water. One of the swimmers is also a cancer survivor, trying to do as much good on land as he does in the water. Eric Shanteau has a lot of titles: Olympic swimmer, world record holder, motivational speaker. But there is one more thing that defines him -- cancer survivor. Two and a half years out from his diagnosis, Shanteau is back in Charlotte for the second year in a row and again hoping to inspire cancer patients. Mi
