Hope is a complex concept and one that is often misunderstood by many people including health care professionals. Many people tend to interchange the terms of wishing, optimism, and hope, but the three have significant differences.

Wishing is usually specific in that you wish for something you desire. It is positive in nature. Optimism emphasizes the positive aspects of a situation and is considered to be a positive trait. Both of these have places in our lives but to live with a disease like cancer and to get through treatments, navigate health care systems, and to overcome society's negative views about cancer as a death sentence, a person must have a strong sense of hope.

In stumbling upon an article published by the National Coalition for Cancer Survivorship written by Elizabeth J. Clark, PhD entitled "You Have The Right To Be Hopeful", I realized that without this inner strength, this determined will power, this drive, that hope creates, there would be a lot less survivors in this disease. It is a good read and I am passing along the link to the free PDF file for others to enjoy and learn from.

Journalist, commentator, and cancer patient Leroy Sievers -- the guy we've written about before, the guy who has covered many wars and witnessed countless deaths, the guy who is now observing his own death as cancer in his lungs and spine chip away at his life -- has realized that getting good news takes some getting used to.

Sievers got some good news recently. He learned that the new combination of chemotherapy drugs he's been receiving has shrunk the tumors in his lungs. And scans show the tumor on his spine is healing. It's taken him days to truly understand this concept -- this concept of hope that has miraculously delivered him more time. He didn't expect it.

Sievers fully expected that he would soon be dead. That's why he's been savoring the cold, crisp fall days -- because he was not certain he would ever see such a season. He was sure he would never host another Halloween party either -- a party he canceled this year due to his health. But now, as he takes in this new sensation of hope, he considers the possibility he may be around for another party. And he thinks he'll dress up as a tumor. Halloween is one time when good taste is never important, he says.

Sievers, who offers a weekly personal health update for NPR, available in print or in podcast format on his blog, plans to keep living in the moment. He doesn't want to overdo this hope thing. So right now, he is simply enjoying the colorful leaves -- and the season he calls one of his favorites.
