Kaycee Marie Macdonald, now 12 months old, was diagnosed with neuroblastoma in May. So far, Kaycee has had 2 operations, one because her kidneys were failing and another to implant a tube in her chest for chemotherapy drugs. Every three weeks, she undergoes three days of chemotherapy. Friday, July 7, was just another day at the Jimmy Fund Clinic for Kaycee and her mother Kerri Macdonald, as Kaycee would be getting chemotherapy.

But that day would be different. As Kerri said in a CBS4 Boston television interview, "It's nice when the adrenaline rush is because of something happy and not for fear." The adrenaline rush of happy had to do with a surprise visit from Sheryl Crow. In town to perform at Fenway Park with Dave Matthews that night, Crow stopped in to visit with children being treated for cancer at the clinic. There she met baby Kaycee, where both cuddled and spent a little time together. For Kaycee's mother, it is a bright moment that she can hang onto in memory for the continued dark journey of worry and concern.

Not only that, but Kaycee, by being featured on the evening news, has captured the hearts of a whole new large family of viewers who will keep her in their thoughts and prayers -- and perhaps help the family out with donations as they struggle to get the care Kaycee needs to survive her cancer. With the visit from Crow, Kerri has started blogging about Kaycee. Kaycee is such a sweet little girl. You can watch the CBS4 Boston television interview video here.

According to Medline Plus, neuroblastoma is a form of cancer that occurs in infants and young children. It is rarely found in children older than 10 years. The cells of this cancer usually resemble very primitive developing nerve cells found in an embryo or fetus. The term neuro indicates nerves, while blastoma refers to a cancer that affects immature or developing cells.

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.
