The number of men who die of this cancer are declining in North America because there are more quitters.
The American woman has grown since 1950, mortality for this cancer, by 550%. This proportion is lower in Spain because she belatedly started smoking more generally.

In the UK and the U.S., lung cancer causes more deaths than breast cancer since 1987. In North America, 150,000 women die each year from diseases related to snuff, of these 41,000, die from lung cancer and 10,000 for other cancers. This year there will be about 169,000 new cases of lung cancer deaths.

The survival rate at one year (time during which no disease) in 1995, is 41%. This percentage fell to 14% when it comes to five-year survival. This rate increases to 42% if the cancer is detected early.

90% of people with this disease are smokers, while only 5-10% of smokers with cancer, your chances of developing the disease are fifteen times higher than in nonsmokers.

The snuff smoking is the main cause in 90% of cases of lung cancer in both men and women. Decades ago, this tumor was much less common in women and it was featured it was more likely that was not related to snuff. These differences are disappearing rapidly, reflecting the incorporation of women with smoking in the previous years.

Another part of this type of cancer is caused by inhaled substances and who are in the workplace, a phenomenon related to the 10% -15% of lung cancer in males and 5% in women. The most important of these substances are asbestos, such as those used in asbestos factories.

Lung cancer can also be caused by radiation received at the chest, such as treatment with radiation therapy used to treat breast cancer and lymphoma. The interval between radiation exposure and cancer onset is usually very long, around age 20. The greatest risk are people who tried for many years with old appliances, and smoked during the following years. The risk with modern radiotherapy equipment is very low.

Hereditary factors have little relation to lung cancer.
