Four US lawmakers are attacking the use of chewing tobacco at Major League Baseball games.
The four senators wrote a letter to baseball union head Michael Weiner saying the use of tobacco influences children who see players dipping on the field. The lawmakers want baseball to ban smokeless tobacco use on the field and on camera.
Chewing tobacco in baseball dates back to the 1800's.
Mammograms and false positives
US researchers say more than half of women who undergo a mammogram will get at least one false positive over a ten year period.
Analysts found more than half had a false positive in a ten year period and between seven and nine percent would have a biopsy that didn't find any cancer.
The risk of a false positive was about the same for women in their forties or fifties. However women who started screening in their forties had a higher risk over their lifetime of having that false positive.
Pap test still the best
After a lot of research, doctors are saying the pap test remains the best way to detect cervical cancer in women.
Researchers used data from four studies involving more than 140,000 women. The report says human papillomavirus – or HPV testing -- is more sensitive but less specific than the pap test.
Results show HPV testing on its own yields too many false positives. This could result in unnecessary medical costs and anxiety for many women.
