OK, women of the world. Grab some paper and a pen and jot down this list of seven check-ups every woman needs. Don't just write them down, though. Make sure you take action on each and every one. They might just save your life.

1. Start with your weight, height, and BMI (body mass index). The scores you get on these simple tests are important because many conditions and diseases are associated with being overweight or underweight.

2. Check your blood pressure, and find out where you stand because hypertension is a disease with no symptoms. High blood pressure puts you at risk for cardiovascular disease -- but there are very effective treatments for this condition.

I just took the Great American Health Challenge -- an on-line quiz offered by the American Cancer Society -- and after just a few minutes of answering a few questions about my age; weight; height; family history; and eating drinking, smoking, and exercise habits, up popped my very own Health Action Plan.

My plan was quite revealing and listed both the good and not-so-good facts about my lifestyle.

I learned that my weight is normal -- whew! -- and that I seem to have an active enough fitness routine. More is always better, though, I was informed. I digested the fact that I don't eat enough whole grains and probably need more low-fat dairy in my diet. I was commended for not smoking and not drinking. And I was encouraged to limit sugars because they are high in calories and low in nutritional content.

My plan came to me ready to print so I can take it to my next medical appointment where my physician can help guide me toward healthier living.

American Cancer Society experts say the Great American Health Challenge can help those who take it to lower their risk of cancer. Get checked, get moving, nourish your body, and quit smoking, they say.

The ABC building in the Brisbane suburb of Toowong -- subject of a December 2006 post -- has been officially vacated following an investigation that turned up a cancer cluster among female employees.

Over the past 11 years, 10 women from this one building have been diagnosed with breast cancer. Eight of the women worked in the ABC newsroom, and most had been there for more than five years. The breast cancer risk for these women was six times higher than for the general population of women in the area. And while the investigation continues and clues are beginning to connect, the big question -- Why? -- has still not been answered.

It has been determined it is highly unlikely the increase in breast cancer was caused by exposure to radio frequency, low frequency electromagnetic radiation, or chemical contamination. According to experts, had any of these factors been at play, there would have been a rise in cancer among male employees as well as female employees. Therefore, it appears something specific to women has caused this cluster.

Perhaps clues will emerge from an analysis of lifestyle influences -- like smoking, diet, and alcohol and medication use -- and already women have answered questions pertaining to body weight, height, level of physical activity, and reproductive history.

One common theme among women is the use of oral contraceptives for periods varying from two to 18 years. Other interesting findings include the average number of babies born to the women -- 1.6 -- and the breastfeeding practices of the women -- each woman with a child breastfed for an average of 2.3 to 12 months -- and the educational background of the group -- of the 10 women, six have college degrees.

Experts says these are important factors. Early puberty, late menopause, lack of breastfeeding, use of oral contraceptives, and the trend of older mothers having fewer babies all can influence breast cancer risk. And so can level of education. Research shows increased rates of breast cancer in women with white collar jobs -- which is related to socioeconomic status and late childbearing.

Everything is important really -- because as breast cancer rates continue to skyrocket, all possible reasons need to be considered.

One in eight women in Australia will be diagnosed with breast cancer before the age of 85. About 13,261 women were diagnosed with breast cancer in 2006. And it is predicted that 14,818 will be diagnosed in 2011.

I think obesity will always carry with it a risk for health problems. And according to a new study released on Monday, men with prostate cancer who are overweight have a higher risk of tumor recurrence after radiation treatment than thinner men do. Specifically, moderately and severely overweight men had a 70 percent higher risk of recurrence than men who were not overweight -- as indicated by rising levels of PSA, a blood protein that can signal prostate cancer. It is not clear how exactly obesity affects the success of radiation treatment -- perhaps it's the fat tissue that secretes certain hormones that helps the cancer progress at a later time. Regardless, the study suggests that men who are overweight do not fare as well as those who are at an average weight -- and this gives men a definite reason to trim down.

Obesity in this study was characterized by body mass index -- BMI -- a statistic that takes into account height and weight. A man five feet, 10 inches tall would be considered normal weight at or below 184 pounds. He would be overweight at 185 to 209 pounds, mildly obese at 210 to 244 pounds, and moderately to severely obese at above 244 pounds. Moderately to severely obese men had almost twice the risk of developing elevated PSA levels, according to an epidemiologist who led research in the study -- which will be published in the August 1 issue of the scientific journal Cancer.
