It is reported that in 2005, carcinoma of the lung will account for 31%
of cancer deaths in males and 27% of cancer deaths in females.
It is estimated that in 2005 there were 92,305 cases of lung cancers in men and 79,544 cases in women.
- Seventy percent of all lung cancer deaths occur between the ages of 55 and 74.
However, recent trends indicate that both the incidence and mortality of lung cancer is
increasing in younger age groups.
- The incidence of lung cancer:
Males > 70 per 100,000
Females > 22 per 100,000
It is approximately three times more common in men than females. However the
incidence of lung cancer in females in increasing in epidemic proportions.
- Cancer Death in Women
incidence of female lung cancer continues to increase and has surpassed breast cancer as a
leading cause of cancer deaths among women. Currently, carcinoma of the lung accounts for
12% of all new cancers in women and 27% of all cancer deaths.
- Lung cancer has been the leading cause of cancer deaths among males
since 1955. However from 1955-1985 the incidence of lung cancer deaths among males has
increased from 30 per 100,000 to greater than 70 per 100,000. In 2005 lung cancer
accounted for 13% of all new cancers among males and 31% of all cancer deaths.
- The countries with the highest incidence of lung cancer among males is the United Kingdom (90 per 100,000 males). The lowest incidence of lung cancer occurs
in Asia and Africa. Rates for most of North America and Europe are between these two
extremes. In general, the incidence of lung cancer in industrialized western countries is
increased compared to third world countries. This difference is most likely attributable
to increased cigarette smoking. However, other factors such as the presence of ceratin
industries (chemical, petroleum and shipbuilding) and increased levels of air pollution
may play a lesser role.
- The highest incidence of lung cancer in the United states, according to a 20 year
review of mortality form all the cancers in the United States is in the northern urban areas and along the gulf and south Atlantic Coasts from Texas to Florida.
Farming areas were found to have a lower incidence than other areas, including rural
