"People don't often understand how a tiny skin blemish can kill," wrote Sarah Toller in her July 2, 2006 blog entry. Yet it call kill. And it killed Sarah on Tuesday, June 12, 2007.

On June 10, I wrote about Sarah. I wrote about how melanoma was claiming this young woman, how her husband was writing the final chapters of his wife's life on the blog she began just more than one year ago.

I visited Sarah's blog yesterday and read a closing statement written by her beloved. It was simple, to the point, and terrifyingly sad.

Sarah has been blogging about her battle with melanoma since May 2006. She begins with a post titled Something About Sarah where she chronicles the series of events leading up to her diagnosis.

July 2004

Have a bit of pain in right arm. Feels like "10 bees stinging me at once" deep inside my arm. Thought I pulled something at gym.

August 2004

Still have same occasional pain but not worried in the least. I'm enjoying my summer and playing soccer. Have tons of energy, working full time and going to school. Moving at end of August.

In response to the post Thought for the Day: These Small Hours, a song by Matchbox 20's Rob Thomas, reader Mary H. shares the name of another beautiful song by artist Sarah McLachlan. The song, Ordinary Miracle, is from the Charlotte's Web movie soundtrack and for Mary -- and me too -- it evokes an inspiring live-for-the-moment type of message.

Think about this:

It's not that usual when everything is beautiful
It's just another ordinary miracle today

The sky knows when its time to snow
You don't need to teach a seed to grow
It's just another ordinary miracle today

Life is like a gift they say
Wrapped up for you everyday
Open up and find a way
To give some of your own

Isn't it remarkable?
Like every time a raindrop falls
It's just another ordinary miracle today

Birds in winter have their fling
And always make it home by spring
It's just another ordinary miracle today

When you wake up everyday
Please don't throw your dreams away
Hold them close to your heart
Cause we are all a part
Of the ordinary miracle

Ordinary miracle
Do you want to see a miracle?

Its seems so exceptional
Things just work out after all
It's just another ordinary miracle today

The sun comes up and shines so bright
It disappears again at night
It's just another ordinary miracle today

It's just another ordinary miracle today

The Boston Marathon takes place today. And one runner -- known to friends and family as Running Bear -- will run to raise money for brain tumor research. She's already collected more than $3,500.

Harvard student Sarah MacCarthy, 25, will run for her Uncle Tim, who is battling glioblastoma (GBM), the most aggressive form of the primary brain tumors known collectively as gliomas.

If Uncle Tim can fight for his life, MacCarthy can use her privilege of good health to make a difference -- even if it means stepping up her casual running to marathon standards.

The Brain Tumor Society will benefit from MacCarthy's determination. Dedicated to improving quality of life for patients, survivors, and families affected by this disease, BTS is committed to being a national leader in the quest for a cure.

It seems MacCarthy is pretty committed herself. To contribute to her efforts and check on her progress, click here.

When she asked her teenage daughters whether or not she should accept the American Cancer Society's Mother of the Year award, the response was a resounding, "Mom, of course." So Sarah Ferguson, the Duchess of York, accepted the anti-cancer honor this week and told ABC's George Stephanopolous on Sunday why she is a good mom and a healthy role model.

"They see that I go running, I get on my bicycle, I do yoga, pilates, whatever else I do," Ferguson said. "Do you know what they do? Get up off the sofa, turn the television off, walk to work, walk around the block, more vegetables, more fruits at school, less soda pops, less fast food."

Ferguson, 47, says cancer prevention starts with good role modeling -- which is exactly what she has done as mom to princesses Beatrice and Eugenie.

"I can safely say one of the best things I've done is be a good mother," Ferguson said.

Ferguson, author of memoir My Story and spokeswoman for Weight Watchers, first became known as the wife of Britain's Prince Andrew, the Duke of York. The pair divorced in 1996, but Ferguson's positive public persona has remained untarnished.

Geralyn Lucas, author of the memoir Why I Wore Lipstick to my Mastectomy can see the pages of her book come to life on the television screen this October -- during National Breast Cancer Awareness Month -- when Lifetime TV airs her story and spreads her word for all to see. Headlining in this Lifetime Original Movie are Sarah Chalke (Scrubs) and Jay Harrington (Desperate Housewives) whose performances will capture Lucas' struggle after a breast cancer diagnosis at age 27 and with a mastectomy, six months of chemotherapy, and a job she maintained throughout it all. Her job -- as an assistant story editor for the TV news program 20/20 -- kept her sane. While her physical world was falling apart, her mind was still working. And that -- along with a promotion during the same time -- kept her focused.

After her 1995 diagnosis, Lucas found herself working as Lifetime's own programming director. She also found herself as mom of post-cancer daughter Skye, and then found herself in the midst of writing a book. It wasn't her goal to write a book really -- but she took a writing class which prompted her to jot down her personal breast cancer story. And the rest is history -- and coming soon to a television screen near you. So stay tuned for October's programming schedule -- and find out why exactly Lucas wore lipstick to her mastectomy.
