Executive director Carlea Bauman will ring the NYSE Opening Bell in honor of Colorectal Cancer Awareness Month, and you don't have to be in New York to witness the wonder of it all.

The Colorectal Cancer Coalition, also known as C3 and headquartered in Washington DC, pushes for research to improve screening, diagnosis, and treatment of colorectal cancer; for policy decisions that make the most effective colon and rectal cancer prevention and treatment available to all; and for increased awareness that colorectal cancer is preventable, treatable, and beatable.

At the end of November, EarthLink CEO Garry Betty took a medical leave of absence from his job to fight adrenocortical cancer, a serious form of cancer characterized by a tumor that occurs in the adrenal glands above the kidneys. On Tuesday, Betty died at his Atlanta home from complications of the disease. He was 49.

Betty joined the internet service provider EarthLink in 1996 and helped the regional company grow from a provider with 500,000 subscribers into a national powerhouse with more than five million subscribers.

"Garry was instrumental in building EarthLink into the company it is today," EarthLink Chairman Robert M. Kavner said in a recent statement.

EarthLink was just one of Betty's successful ventures. He began his career at IBM Corp. and won the IBM President's Excellence Award in 1982 for his work on the company's personal computer. He also served as CEO of Digital Communications Associates Inc. and at the time became the youngest CEO of a company listed on the New York Stock Exchange.

Betty, who graduated from the Georgia Institute of Technology in 1979 with a degree in chemical engineering, was responsible for 2,200 EarthLink employees. And in support of his team, he attended the company's 2006 Christmas party just three weeks after receiving his diagnosis.

"He put on a tux and came out for a night to make all of us feel better," said Mike Lunsford, interim EarthLink CEO. "And he succeeded."

Betty is survived by his wife, Kathy.

Several boxes containing injections of Neulasta have lined the bottom of my refrigerator for more than a year. They are left-overs from chemotherapy -- from a time when one needle pierced the skin on my arm after each chemo treatment to keep my blood counts in a safe range. I've looked at them day after day after day, and I've allowed them to sit in the same exact spot for all this time. But today, they are in the trash -- not because I made a conscious choice to throw them away but because water spilled all over the inside of my refrigerator and left them soggy and damaged. Surely I would not have used them in this condition, I thought -- so I tossed them. But really, I would not have used them anyway. They were old -- probably past their expiration date -- and I am not receiving chemotherapy anymore. I had absolutely no use for them. But I kept them for safety or comfort or some other impractical reason -- for the same reason I keep a basket full of old medication in my kitchen cupboard. It's all cancer-related -- most of it never touched because I don't really like taking medication, even when necessary. So this stock-piling tendency defies all logic for me. Until today -- when part of my past sits in a white trash bag, ready for the curb, and the rest of it is soon to be trashed. So I can continue moving forward. Away from cancer. For good.

Dealing with cancer in private is hard. Dealing with cancer publicly can be even harder. CEO Donna McAleer -- the founding executive and public face of the large, growing health care company Elant -- knows this firsthand. She just recently went public with her breast cancer diagnosis and prognosis after rumors of her demise started circulating. McAleer set the record straight, announcing that she is doing just fine. While her experience has been frightening, she is surviving well -- and she wants the public to know. She has run Elant for 20 years and wants to dispel any myths about its stability. Apple CEO Steve Jobs faced the same public drama in 2004 after surgery for pancreatic cancer and subsequent drops in Apple stock. Jobs recovered -- and so did the stock -- but the speculation that swirled was powerful and potentially damaging. Just as it was that same year when Kraft Foods was criticized for withholding details of its CEO's hospitalization.

There is some debate in the business world about all of this -- about whether or not executive illnesses should be disclosed. For public companies, one opinion is that there is an obligation to respond quickly to the public. In a private company, it's up to the CEO. McAleer's Elant is not a publicly traded company and there is no worry about stock price -- but her decision to reveal her personal health crisis was the right thing to do, she says. "I have an obligation to share this news in how I progress, in order to educate and make sure people aren't frightened by it," she said in reference to the memo she sent to her 700 employees and community groups too.

I'm open and honest about my own cancer experience because I believe it can help others -- and it helps me to talk about it too. So I'm a fan of a forthcoming approach in the workplace. I appreciate that some fear repercussions that might result from such a disclosure. But honesty may be the best policy -- for prevention of rumors and addressing worry and raising awareness too. McAleer seems to agree as she takes this opportunity to speak up, to encourage women to seek mammograms and to follow up on them.
