Women Have A Higher Incidence Of Lung Cancer Than Men


According to a new study published in the International Journal of Cancer, women aged 30-49 have a higher incidence of lung cancer than men of the same age.

The study involved cancer scientists in Canada, France, Dr. Ahmedin Jemal and the Master of Community Health Sciences of the American Cancer Society (ACS) - Lindsey A. Torre. They looked at rates based on data from people diagnosed with lung cancer for a year in the same country. Also, compare the ratio of men to women in the 5-year-old age groups (starting from 30-34 to 60-64 years) in 40 countries across 5 continents and over a 5-year period, starting from 1993 - 1997 to 2008 - 2012 group.
In those years, the incidence of men often decreased in all ages in all countries. For women, this rate remains the same or decreases at a slower rate than men.

Historically, the higher rates of lung cancer in men are mainly due to the way they smoke. However, in recent times, this rate has been higher among women aged 30 to 49 in 6 countries: Canada, Denmark, Germany, New Zealand, the Netherlands and the United States. The researchers found similar trends in 23 other countries on levels of economic development, including some in Africa and Asia.

This is due to an increase in adenocarcinoma, a type of lung cancer found in smokers. This type of lung cancer is also the most common type seen in non-smokers and is more likely to occur in young women.

Jemal, scientific vice president of the ACS Monitoring and Health Services Research Program, said in countries where a higher proportion of young women (30 - 49 years old) have lung cancer than men of the same age, Women do not consume cigarettes more than men.
 "This shows that the difference in the way men and women smoke cannot completely explain why the diagnosis rate in young women is higher," he added.
 Scientists speculate that the higher risk of lung cancer in women is related to the retrofit of tobacco tools for years or how women respond to the carcinogens in cigarettes. As follows:

Many women start smoking during the years when filtered cigarettes become the most popular. Filtered cigarettes increase the risk of adenocarcinoma (adenocarcinoma) because they make smoke distributed to the outer parts of the lung.

Women may have genetic factors for lung cancer other than men, such as unable to repair damaged DNA or have abnormal genes related to cancer development.
Scientists recommend that people stop smoking or using other tobacco products.
The authors also urge scientists to do more research to determine why lung cancer rates are higher in women in many countries, and recommend that people continue to increase their call for stopping smoking or using other tobacco products.
