My six-year-old Joey told his grandmother -- my mom -- the other day, "Nana, you are generous." It was thoughtful and touching and it brought a smile to her face. Later that night, Joey said the same to me. "Mom, you are generous," he proclaimed. And now I'm not sure if he really meant his sweet sentiments or if he was just practicing one of his new kindergarten vocabulary words. Regardless, it got me thinking about how generous his Nana really is.

My mom not only generously gave me life. She also saved my life -- not in the medical, scientific manner surgeons and oncologists saved my life but by the sheer force of love, support, comfort, and undying devotion that seems to involuntarily pour from the hearts of moms with sick children.

It seems screening for lung cancer doesn't save lives and it doesn't prevent advanced disease. But it does lead to potentially unnecessary and harmful treatment.

This isn't the final word on the use of CT scans to screen smokers and former smokers for the disease. But right now, the hope some experts had for the special X-rays to detect tiny lung abnormalities has been diminished by a large study that is still in the works. And until conclusive evidence says the screening is useful, the American Cancer Society will not endorse the test.

While CT screening did increase diagnosis and treatment -- those screened were three times more likely to be diagnosed with lung cancer and 10 times more likely to have lung surgery than predicted -- study co-author Dr. Peter Bach of Memorial Sloan-Kettering Cancer Center in New York says, "We don't see a trace of evidence that a single life was saved, that a single case of advanced cancer was avoided."

And because CT scanning led to more biopsies and surgeries, patients were put at risk for complications such as lung puncture, bleeding, and infection, according to Bach, whose work is published in the Journal of the American Medical Association.

"Getting screened for lung cancer with CT scanning is not only unproven, it's potentially a risky endeavor," he said.

Until an effective screening tool emerges -- possibly still years away -- experts say there is one surefire way to protect yourself from lung cancer. Stop smoking.

Kids can be so positive and encouraging, even in the face of sickness. Now today my kids have just a simple sickness -- nothing life-threatening -- that I'm sure will pass in a day or so. They are throwing up every content of their little tummies -- even sips of water -- and they are pale and lethargic and run-down. But still, they have hope for a brighter tomorrow. This morning, five-year-old Joey said to me while resting in my bed and just after he threw up , "this is just the good getting rid of the bad." He went on to explain how the good in our bodies knows when to push the bad out. And this is what is happening to him today, he said. He is throwing up the bad so the good can take over. Simple. Easy. Makes sense.

I never saw my own sickness like this. Instead of visualizing chemotherapy as a good agent that kills bad cells, I was repulsed by the horrific liquids that poisoned my body. I knew of people who were able to turn chemotherapy into a Pac-Man game -- with Pac Man chomping away at the cancer cells and leaving nothing but healthy cells to thrive. And I knew people who were relieved to feel sick because it meant the chemotherapy was working. I never saw it like this -- although I do know that chemotherapy may have saved me from a life with cancer. I was discouraged by chemotherapy. I had a negative attitude about it, and I had to really gear up for all of my infusions. I still -- more than one year later -- cannot eat anything I ate on my chemo days. The mere thought of these foods makes me feel ill.

A pediatrician friend of mine told me that kids with cancer tend to be positive. There are a few old souls, she said, but for the most part, they continue to tackle life with spirit and adventure and simplicity. Like my boys today who are peacefully napping at the moment so everything good in their bodies can come back with a vengeance.

Coletta Barrett believed her stomach pains were caused by a gall bladder attack after eating greasy fried food. She excused a tightening in her lower abdomen as irritable bowel syndrome, and she explained blood in her stool as a response to stress. Only after a referral to a gastroenterologist led to a colonoscopy did she learn that the upper portion of her colon was almost completely blocked by a large tumor -- a cancerous tumor. Barrett was diagnosed with colon cancer. Her colonoscopy saved her life.

Barrett never once predicted she might have colon cancer. She thought the disease mostly struck older people. She was just 42. Screening tests are not even recommended until the age of 50. She had no family history of this cancer and had no typical risk factors associated with the disease. She did not smoke, was not overweight, and drank very little. But she did in fact have colon cancer -- shocking as it was -- and doctors believed her tumor had been growing for 18 months before detected. Fortunately, Barrett learned that her cancer had not spread. And she learned a few other things that she now shares as advice -- from her survivor point of view. These tips come from an article about Barrett in the August 1 Women's Day magazine.

• Barrett says, "know your body." And don't ignore or dismiss any changes that occur.
• Don't let embarrassment stop you from seeking help. Some symptoms can be difficult to discuss -- such as change in size and frequency of bowel movements, bloody stool, cramping, and bloating -- but still ask your doctor about them. Early detection is critical, she says.
• If diagnosed with colon cancer, learn as much as you can about the disease -- a well-informed patient has a better chance at a better outcome.

Barrett offers sound advice. And I think it is global advice. Knowing your body, discussing symptoms, and education after diagnosis are key for anyone. For everyone.

I remember reading that Barbara Delinsky, novelist and breast cancer survivor, never shared her diagnosis of cancer until well after her fight was over. She feared the news would somehow halt her career in the publishing world. She wanted to remain untainted by disease in the eyes of her readers and bosses so she saved her secret. The secret is out now -- and is also part of a book she wrote called Uplift: Secrets from the Sisterhood of Breast Cancer Survivorship. She is in the clear now -- but she once feared the consequences of managing both cancer and her career.

The experts who offer a website resource at cancerandcareers.org believe that it is possible to combine cancer and career without fear or worry or secrecy. The advice provided on this site offers wisdom for working women and for employers and for co-workers. There is also a forum for shared stories -- where all of these individuals weigh in on their experiences. There are reading recommendations and a listing of available programs and services and a complete story about how this all came about.

Five years ago, the Board of Directors at Cosmetic Executive Women -- the preeminent nonprofit organization representing women in the U.S. and European beauty industries -- realized that five out of their 40 members had been diagnosed with cancer. Some told their colleagues at work and some did not. But all continued to work and experienced similar challenges. The fact is that work does not stop for all women who have been diagnosed with cancer. So the mission of this group is to help women, their employers, coworkers, and caregivers deal with this problem in the same way that they have learned to deal with problems at work -- strategically, knowledgeably, and effectively. With the right tools, stress and difficulty can be minimized. And this site is one great tool.

Mammograms may not be solely for detecting breast cancer anymore -- they may also lead to detection of heart disease. Calcifications may be detected in the arteries of the heart during routine mammograms. Essentially, this indicates hardening of the arteries and can be a sign of heart disease. This is nothing new, really -- doctors have long thought that hardening of breast arteries relate to heart disease. But this relationship had never really been studied -- until recently. Several large studies and many smaller ones have shown a correlation between these vascular calcifications on arteries in the breast because of the similar size to the arteries in the heart. And this correlation revealed itself for one woman -- Bunnie Gleiman -- when she went for her annual mammogram and learned that she had these calcifications on the arteries in her breast. She says her mammogram saved her life -- but not from breast cancer. Now on medications for cholesterol and blood pressure, Bunnie reports that she is happy and healthy. Thanks to her mammogram.

It is estimated that 1.25 billion men and women currently smoke cigarettes. And if this trend holds steady, tobacco will kill 1 billion people by the end of the century -- 10 times the amount of people who died from tobacco in the 20th century. Every one in five cancer deaths results from tobacco use -- worldwide, that's 1.4 million tobacco-related deaths every year. And lung cancer remains the major cancer among the 10.9 million new cases that are diagnosed annually. All this comes from the Cancer Atlas -- updated and released today along with the Tobacco Atlas and published by the American Cancer Society with assistance from the International Union Against Cancer, World Health Organization, and U.S. Centers for Disease Control and Prevention.

While improving nutrition and reducing infection can dramatically reduce cancer rates, reducing tobacco use would have the greatest global affect the number of cancer deaths. And if action is taken now, 2 million lives could be saved each year by 2020 and 6.5 million lives by 2040.

There has been a great increase during the past 10 years in the number of women receiving mammograms in Florida. But shockingly, almost one million Florida women over the age of 40 have still not ever received mammograms. So the American Cancer Society has teamed with the Medical Quality Assurance Inc. -- and they have co-published a guide to help these women locate a mammography center that meets their needs. This guide is sorted by city and is available on the American Cancer Society website for quick and easy access.

I can only imagine how the numbers stack up in consideration of all states -- and not just Florida. I can only imagine why these one million women in my state alone have not reported for this critical test --perhaps reasons stem from lack of awareness, lack of access, lack of financial resources, lack of concern. I can only imagine that not everyone -- due to life circumstances -- can be a recipient of this potentially life-saving test. Like I was -- at the age of 34 with a small but aggressive cancerous tumor living in my left breast. My referral for a mammogram saved my life. And I can only imagine how many more women might be saved from the horror of breast cancer because a mammogram assisted in early detection. I can only imagine that the day will somehow arrive when all women -- of all ages -- are afforded the opportunity for this test. And that those who have the opportunity -- and the means -- decide to delay no further.
