It's been one year since Dana Reeve, wife of the late Christopher Reeve, died of lung cancer at the age of 44. And the grace of this woman, who came to represent the non-smoking population of lung cancer victims, is being honored by the Lung Cancer Alliance.

"Lung Cancer Alliance extends its most heartfelt thoughts to the family
and friends of Dana Reeve," says Laurie Fenton, president of the alliance.

"Dana's beauty, grace and valiant struggle against lung cancer will remain indelibly etched in our hearts and minds. In her memory -- and in the memory of loved ones lost to this disease, smoker or not -- let us come together to replace decades of stigma and neglect with hope, greater compassion and support for those living with or at risk for this disease. It is the right thing to do."

The Lung Cancer Alliance is the only national non-profit organization dedicated to patient support and advocacy for those living with lung cancer, the number one cancer killer.

Lung cancer takes more lives -- about 160,000 Americans this year -- than breast, prostate, colon, liver, kidney cancers and melanoma combined.

Dr. Len Lichtenfeld, MD, is the deputy chief medical officer for the American Cancer Society. He is also a blogger and authors his very own blog -- called Dr. Len's Cancer Blog.

Dr. Len writes on his blog about all sorts of topics related to cancer. He shares his opinion on the recent drop in breast cancer cases (December 15, 2006), he promotes the Great American Smokeout (November 14, 2006), he sounds off on lung cancer screenings (October 25, 2006), and he urges parents to always slather sunscreen on their children (October 5, 2006). He has so much more to say -- and his blog is a great stop for those wishing for more information on hot cancer topics.

As this year comes to a close, Dr. Len offers a review of what he believes were the hottest cancer topics of 2006.

Dr. Len reflects in his blog about decreased cancer death rates that represent real progress in the fight against cancer. He calls the HPV vaccine a breakthrough and he recaps the STAR trial -- a comparison of raloxifene to tamoxifen to reduce the risk of recurrent breast cancer in post-menopausal women -- with emphasis on how raloxifene proved just as effective as tamoxifen, but with a better safety profile. He calls new targeted therapies a dream -- with a hefty price tag -- sure to garner debate and discussion in 2007.

Dr. Len reviews the Surgeon General's report on second-hand smoke -- it's harmful to non-smokers, the report says -- and he marvels at the capability of science to approach an understanding of what makes a cancer cell a cancer cell. He also remarks on how remarkable it is that chronic myelogenous leukemia is in fact chronic and no longer fatal, thanks to the drug Gleevec.

Of course, there is ample attention given to the declining incidence of breast cancer, reportedly due to less women using hormone replacement therapy, and the risks weighing on those who are overweight and obese, and survivors and supporters who gathered for Celebration on the Hill -- the site of one incredible American Cancer Society event.

Dr. Len closes his review of 2006 with recognition of three celebrities who lost their lives this year to cancer -- Dana Reeve, Ann Richards, and Ed Bradley. And while he recognizes there are other lives and other stories that deserve mention, there is simply not enough time or space for him to do justice to every noteworthy item.

"What we have seen over the past year is an incredible leap forward in cancer research, diagnosis and treatment, and I suspect there are going to be even more exciting developments in the coming year," says Dr. Len who looks forward to 2007 -- a year that is sure to deliver more hope and more progress in the fight against cancer.

In the second part of the two-part exclusive interview with ABC's Good Morning America Diane Sawyer, Sheryl Crow shares she is cancer-free and feeling great as a breast cancer survivor. The diagnosis of breast cancer came as a surprise as she is not a smoker and has no family history of the disease. She received enormous support from her family and friends during treatment, whom she refers to as "this incredible tribe of women." Before Dana Reeve died of lung cancer, she gave Crow advice on dealing with the emotional aspects of being a newly-diagnosed cancer patient and dealing with the recent separation from Lance Armstrong by telling her that the only way to go through grief was to grieve.

Crow talked about meditating and changing her diet. "I kind of went into a full-on Eskimo diet, where I ate a lot of salmon. In fact, I'm salmoned out of my brains ... and really green vegetables, just eating really clean, organic food. Listen, I haven't had a doughnut in I can't remember when."

Breast cancer forced Crow into an introspective place of self-realization in facing and overcoming fears -- and the wisdom that comes with that when she said she tried to at least address her fears and not be overcome by them. "The fear of things not always working out. You come to a point in your life where you realize it's not my job to prove to my parents or to my record label or to the world or to my lover that I matter. The fact is that you matter."

"It's not a good place to be concerned with always being right with everybody, always pleasing people, because ultimately you wind up betraying yourself a lot."

Crow shared that she sees her breast cancer diagnosis and being a cancer survivor as part of life's deepening experiences where obstacles are removed and opportunities come in.

Last Friday night, Crow joined the Dave Matthews Band in a concert at Fenway Park. But before she went onstage -- in part of giving back as a cancer survivor --  she made an unannounced surprise visit to Boston's Dana-Farber Cancer Institute to visit children with cancer at the Jimmy Fund Clinic.

Five years ago, President Bush restricted federal funding for any new human embryonic stem cell research. Many believe the objections are based soley on religious convictions, and without scientific or true ethical merit. The argument against Bush's stand has been that creating embryonic stem cells from a patient's tissues, correcting the genetic defects, and get the repaired cells back into the patient, opens the door to many cures for diseases. At one time or the other, Christopher Reeve, Michael J. Fox and Lance Armstrong have all spoken out against the federal funding ban -- as have many intelligent scientists and respected members in the medical community who see the devastating effects disease or profound physical injury can have on a patient.

Harvard University researchers are going around the federal funding ban by using only private funds and will begin research in an effort to clone human embryos as a source of stem cells. The researchers do not go into this lightly. They have visited the ethical issues at length and created strict standards for the research work and as they said, "to separate out all funding so that not a penny of federal money is spent on the effort." I honor and respect a person's personal religious beliefs -- there are many religions and many different religious beliefs to honor and respect -- but I do not feel it should ever dictate government policy -- especially if it means depriving patients of potential cures to disease.
