A new study published Thursday in the journal Science claims that men are more likely than women to be diagnosed with Cancer if they smoke cigarettes. According to the study’s authors, “It is clear that smoking is very, very bad for you. But apparently, it’s worse for men than for women.”
Researchers believe the results occur because smoking reduces the number of Y chromosomes in blood cells. Y chromosomes are only present in men and previous research has indicated cancer is more likely to occur when men lose many of those chromosomes.
Researchers at Uppsala University in Sweden examined 6,000 men. The group looked for various factors that impacted Y chromosomes such as age, exercise, cholesterol and smoking.
