An independent report revealed recently that women employed at the Toowong site of ABC's former Brisbane studios in Australia were six times more likely to develop breast cancer than other women.

The site has been vacated. And the hunt is on -- for the cause of this unusually high rate of the disease.

No luck yet -- but new findings, while not definitive on what has caused this cluster, do indicate exposure to electromagnetic fields (EMF) is not a factor -- because the low frequency fields at the site were typical of other workplaces and residences, without any such cancer cluster.

Further testing will take place in an attempt to solve this on-going mystery, chronicled in the posts that follow.

I heard the statistic twice this past weekend -- once from a friend who is a drug rep for a prostate cancer drug and once from a friend with a family member struggling with prostate issues.

I had never before heard what hit my ears a few days ago, and I was quite shocked to learn this new cancer tidbit -- so shocked I did some research and discovered that what my friends told me is sadly accurate.

The good news is that the death rate for prostate cancer is going down, and the disease is being found earlier than ever before. The startling news is what I present today as my Thought for the Day.

Think about this:

Nearly 80 percent of men in their 70s develop prostate cancer.

Chloe is a little girl conceived through in vitro fertilization -- not because her parents could not conceive in the traditional manner but because they wanted to make sure Chloe had no predisposition to cancer in her genetic makeup. And in vitro fertilization is one method of almost ensuring this. There is still a three percent chance of failure but Chloe's parents felt confident in the elective process that would mostly prevent her from inheriting a genetic mutation for colon cancer that has devastated her family -- Chloe's father carries this mutation, and his mother, grandfather, and two uncles have all died from colon cancer.

A growing number of couples are using preimplantation genetic makeup to detect a predisposition to cancers that may or may not develop later in life. Using this procedure, parents subject their tiny embryos to genetic tests to determine whether or not they harbor defective genes. Essentially, parents get to pick and choose from embryos in a petri dish which one they want. Since the embryo that became Chloe did not test positive for any defective genes, she was the chosen one. And she is now a healthy two-year-old girl.

It's an ethical minefield -- this scientific creation of human life and the picking and choosing of which embryos will survive and which ones will not. One expert says the issue centers around what is considered serious enough to warrant such testing -- and who gets to make this decision. Ethical dilemmas surrounding this issue will only continue to grow as more and more options become available. Already embryos are tested for predisposition for obesity and deafness and a mild skin condition. Some clinics even screen for gender. Some fear this practice may lead to a genetic class divide where the wealthy will become more genetically pure than the poor -- because this process is difficult and expensive, costing tens of thousands of dollars without insurance coverage.

Chloe's parents are happy they made the choice they did. Her father says he doesn't know if he could handle being told his daughter has cancer -- especially with the knowledge that he could have prevented it.

Lung cancer affects more than 80,000 American women annually. More than 70,000 of these cases are fatal. Thirty thousand more women die from lung cancer than from breast cancer. And lung cancer claims more lives of more women than breast, uterine, and ovarian cancers combined. Yet a new study reveals that American women are uninformed about statistics like these -- and about the threats posed by lung cancer.

A 2006 survey of 500 women provides a snapshot of women's attitudes and beliefs about lung cancer -- and the overwhelming conclusion is that there is a widespread lack of awareness about the nation's top cancer killer. And here's the lowdown:

• Only 41 percent of women know that lung cancer is the leading cancer killer in the United States.
• Only 8 percent of women know that exposure to radon gas is the second leading cause of lung cancer -- 60 percent instead believe that second-hand smoke is the culprit.
• Only 36 percent of women know lung cancer kills more women than breast cancer.
• Only 41 percent of women know that one in 17 women will develop lung cancer sometime in her life.
• Only 4 percent of women know that women typically fare better than men following lung cancer treatment.
• And 25 percent of women mistakingly believe that there is a standard screening test to detect lung cancer in its early stages. Currently, there is not one.

Lung cancer is often believed to be a man's disease. But it is not. It affects tens of thousands of women too. And now I -- as one of the previously uninformed women -- know better.

I will share anything and everything about my own experience with breast cancer -- how I found it, how it was removed, how it was treated, how I fared through the whole ordeal, how I'm surviving now. I figure that if I spread the word about what happened to me, that others will become more aware and some -- especially those with a new diagnosis -- will benefit from whatever wisdom I have to impart. So I am an open book. I talk about breast cancer, answer questions about breast cancer, and probably insert my opinion about the topic to some who don't really care. But I will continue talking and sharing -- and writing -- because the alternative would be a disservice to the few I may be able to help.

So a card stuck in the middle of a magazine caught my eye the other day. The slogan on it reads, Tell Someone and the illustrations on this card -- that functions as a postcard -- show women reaching out to other women. There are women talking on the phone and a woman tapping another on the shoulder. The message they appear to be spreading is highlighted in the text below the graphic representation of this campaign to raise awareness of cervical cancer. The message is about HPV -- human papillomavirus -- and about how millions of women already have it and how some don't even know they have it. I learned from reading this card that for some, HPV will clear on its own. But for some, cervical cancer may develop. This is why Pap tests are critical. And so what all women should be telling other women is this -- ask your doctor about the importance of Pap tests. And be active in your own health. And follow all recommendations for detecting health concerns early. I learned from reading this card that I should tell someone about this. And so now I have.
