ABC News Good Morning America Kate Snow interviewed Los Angeles dermatologist Dr. Jessica Wu about a new herbal supplement being introduced on the American market this summer that is reported to protect the skin from sun damage that can lead to skin cancer.

Heliocare, a tropical fern extract used in Europe for decades to treat the skin conditions of psoriasis and eczema, comes in pill form and is taken daily.

Dr. Wu warns you cannot skip the sunscreen when spending time in the sun because the herbal supplement will not prevent sunburn.

"It gets into your blood stream and works from the inside out, as opposed to sunscreen which works from the outside in," explained Dr. Wu. "So this pill mops up the damage that gets past the sunscreen you might be wearing. It also repairs damage that is done to your skin that leads to skin cancer."

Heliocare is not recommended for pregnant women, nursing mothers, or children. Heliocare is expensive -- a bottle of 60 pills costs $60 dollars. I don't know why, but I was surprised when I watched this news story on ABC News. If something as simple as a fern extract can reverse sun damage to skin and reduce the risk of skin cancer -- and has been on the European market for decades -- why haven't we heard about it here in the US before now? I am not promoting this product -- I am just telling you what I saw on the news. ABC News.

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.

The public liked the idea of Sheryl Crow and Lance Armstrong as a couple, and the media treated them pleasantly when covering them as a couple.

When the marriage was called off, not much was said about it other than announcing it had happened, and the public accepted that sometimes things just don't work out between two people.

However, when the news of Crow's breast cancer diagnosis broke, so soon after the breakup, speculation followed. Had one of the most famous cancer survivors walked out on Crow when the chips were down? It didn't make sense at the time that a man who has dedicated his life to improving the quality of life for cancer survivors would do that -- but since nothing was ever said one way or the other the rumors continued to lurk in the shadows between imagination and fact.

In a two-part exclusive interview with ABC's Good Morning America Diane Sawyer, Sheryl Crow opens up about the breakup with Lance Armstrong and being diagnosed with breast cancer. After being told she had breast cancer, Lance Armstrong was one of the first people she contacted. He was on a solo trip from Lake Tahoe to Oregon. He was about to turn around and return to LA to be with Crow and she told him she did not want him to do that for her. And so, for the personal reasons why the relationship did not work out is a private matter between two good people who insist they still love each other, and past that it should not be our business -- but as Crow makes clear -- Armstrong did not abandon her.

You can watch video clips of the television interview online here, and read the interview in print here. The most inspiring moment came when Crow said,

"People go through challenging moments of losing people and of having their life threatened from illness and real grief. But they get through it. And that's the testament to the human spirit and it's -- we are fragile, but we also are divine."

Part two: Sheryl Crow adopts Eskimo diet to fight breast cancer.
