Health Alert: Reducing CT scans could save lives

Health Alert

(CBS) - Reducing unnecessary CT scans in children and lowering the doses of radiation used in those scans could save lives.

That's according to a new study in the journal JAMA pediatrics. Researchers say the 4 million pediatric CT scans conducted each year result in approximately 5,000 future cases of cancers.

They say the radiation doses used in computed tomography are 100 to 500 times higher than in traditional x-rays.


(CBS) - A new study finds soccer players who frequently "head" the ball perform poorly on memory tests and have brain abnormalities similar to those found in traumatic brain injury patients.

Researchers say soccer players head the ball on average 6 to 12 times per game and up to 30 times during practice drills.

The study found players who headed the ball about 900 times a year or more, had brain scans that were similar to patients with concussions.


(CBS) - New research shows men with prostate cancer may be able to significantly improve their chances of survival if they substitute healthy vegetable fats including olive oil, nuts and avocados for animal fats and carbohydrates.

Researchers say adding a single tablespoon of olive or canola oil a day lowered the risk of prostate cancer death 29 percent.

Adding one serving of nuts a day was associated with an 18 percent lower risk.
