(KTVI) - Marketers used the women's liberation movement of 40 years ago to encourage smoking and sadly, it worked.  Today women are equal to men when it comes to lung cancer risk.

Dr. Maria Baggstrom of the Siteman Cancer Center talks about the results of two studies.  The first, women have caught up to men on lung cancer risk.   In the 1960s, it was only three times higher. One reason: After World War II, women started taking up the habit at a younger age and began smoking more.

In the second study, quitting smoking by age 40 erases most of the risk of an early death.
