5 secrets you should never keep from your cardiologist

Editor's note: These tips were originally published on CNN.com in 2011. To read the full article, click here.

When Rosie O'Donnell wrote about her recent heart attack on her blog, she mentioned several symptoms that she ignored before going to her cardiologist.

"i had an ache in my chest, both my arms were sore... i became nauseous, my skin was clammy, i was very very hot, i threw up... i googled womens heart attack symptoms, i had many of them, but really? – i thought – naaaa."

Heart disease is the number-one killer of both men and women, but O'Donnell's response is common, experts say - especially among women.

Should parents lose custody of obese children?

Researchers from Harvard University say inadequate or unskilled parental supervision can leave severely obese children vulnerable to the societal influences that promote an unhealthy lifestyle and are suggesting that this may be a form of child abuse that authorities should act on.

In a commentary posted Wednesday in the Journal of the American Medical Association, professor Lindsey Murtagh and Dr. David S. Ludwig suggest that severely obese children be removed from their homes, and that government involvement may be justifiable because of the imminent health risks and the “parents’ chronic failure to address medical problems.”

Prenatal exposure to BPA may cause wheezing in infants

 A new study is adding to rising concerns about the safety of bisphenol A (BPA), a chemical used to manufacture plastics and found in hundreds of household products, including plastic food containers, soda cans and reusable cups.

Cancer risk is low, but possible in airport scanners

If you’ve traveled through an airport lately, you’ve probably seen one of the new full body X-ray machines called a backscatter, a type of imaging technology used by the Transportation Security Administration  to identify concealed items.

A special article published Monday in the  Archives of Internal Medicine says “passengers should not fear.”  The device, which raised concerns among some because it uses small doses of ionizing radiation, a known carcinogen, poses “no significant threat” even to  frequent fliers, the authors say.
