Lung cancer

In the Nordic countries, lung cancer (pulmonary cancer) is one of the most common forms of cancer. In Norway, lung cancer is the second most common cancer in men and the third most common cancer in women.

The absolute numbers are increasing for both sexes, most notably for women, where an annual increase of 5 % is observed.

Lung cancers are primarily divided into:

  • non-small cell lung carcinoma (about 85%)
  • small cell lung carcinoma (about 15%)

Together, non-small cell lung carcinoma and small-cell carcinoma constitute about 97% of all carcinomas in the lungs. They have a strong positive correlation with smoking. 

There are several subtypes of non-small cell lung cancers, the most common ones are: 

  • adenocarcinoma
  • squamous cell carcinoma
  • large cell carcinoma

Carcinoid tumors, sarcomas and carcinomas of the salivary gland type are rare and not related to smoking. Mesotheliomas are tumors originating from the pleura and in rare cases from the peritoneum.

Incidence

Of the 2856 new lung cancer cases in Norway in 2013, there were 1555 men and 1301 women. The absolute numbers are increasing for both sexes, most notably for women (33).
