Non-smoker
lung cancer statistics
Two-thirds of non-smokers with lung cancer are women, and 20 percent of lung cancer in women occurs in individuals who never smoke. This percentage is significantly higher in Asian women.
From a number of factors triggering lung cancer in non-smokers, it is known that pollutants harmful chemicals such as aerosol gases, cigarette smoke and asbestos dominate cancer-triggering factors. Some of the trigger factors (non-smokers) that cause lung cancer are:
Radon - Exposure to radon gas in our homes is the leading cause of lung cancer in non-smoker individuals. Radon is a chemical element with atomic number 86 which in chemistry is given the symbol of Rn.
Cigarette smoke - Cigarette smoke is responsible for about 3,000 lung cancer deaths each year in the US.
Exposure to asbestos - Exposure to asbestos in the workplace is an important trigger factor of mesothelioma, cancer of the lung lining.
Aerosol oil - Smoke from cooking is considered an important cause of lung cancer in women in Asian countries.
Genetic predisposition - Individuals with a family history of lung cancer are more likely to develop lung cancer by themselves.
Human papillomavirus (HPV) - HPV is found in lung cancer cells, but whether the virus triggers lung cancer is still unknown.
Type of non-smoker lung cancer
More than half of lung cancer cases in smokers are classified as squamous cell carcinoma (a type of non-small cell lung cancer or Non-small cell lung cancer). While the majority of lung cancer suffered by non-smoker individuals is adenocarcinoma (another type of non-small cell lung cancer or Non-small cell lung cancer).
Squamous cell carcinomas tend to grow near the airways with early symptoms such as coughing or coughing up blood (hemoptysis). While Adenocarcinoma often grows in areas outside the lungs and can appear for a long time before symptoms occur. Commonly induced symptoms such as shortness of breath, fatigue, or symptoms due to the spread of cancer to other areas of the body (such as bone pain) may be more common.
Bronchoalveolar carcinoma (BAC) is another form of lung cancer that is more common in nonsmokers, especially young non-smokers. For unknown reasons, the incidence of BAC seems to continue to increase worldwide.
Types of Lung Cancer
Lung cancer is divided into two main types based on the appearance of lung cancer cells under a microscope. The first type of lung cancer is small cell carcinoma (small cell lung cancer) which is a type of cancer accounted for about 15 percent of all lung cancers. As the name implies, the cells are smaller than the cancer cells in general. They also reproduce quickly and form large tumors. This type of cancer can also metastasize, or spread to other parts of the body. Lung cancer small carcinomas themselves are subdivided into two types:
* Limited: cancer is only limited to the chest area.
* Extensive: cancer has spread to other areas of the body.
This type of cancer can respond to treatment, but it is difficult to cure.
The second type is lung cancer not small cell carcinoma (Non-small cell lung cancer). This type of cancer is much more common than small tuberculosis lung cancer. This type of cancer accounts for about 85 percent of all lung cancers. Lung cancer Non-cell carcinomas can also be subdivided by cell types found in cancer, namely:
* Squamous cell carcinoma (also known as epidermoid carcinoma). The development of this type of cancer starts inside the epithelial cells lining the airways. It is possible that it may develop in larger breathing vessels. If left untreated, this cancer can metastasize (spread) to lymph nodes, adrenal glands, liver, bone and brain. The most common cause of squamous cell carcinoma is smoking.
* Adenocarcinoma: The development of cancer begins in cells that produce mucus in the lungs. This type of cancer is quite common in the United States. Its development has been linked to smoking habits, but it also affects many non-smokers. The development of this type of cancer is usually very slow although it is also possible to develop quickly, causing death. The spread of cancer cells often spreads to the brain. It may even metastasize to lymph nodes, liver, adrenal glands and bones.
* Large cell carcinoma: This type of cancer is responsible for about 10-20 percent of cases of lung cancer. Large cell carcinomas include lung cancer that can not be classified as two types of cancer mentioned above.
