What we know about lung cancer is changing day by day. Lung cancer, which was considered as the only smoking-related disease in the past, is now considered a complex disease with different subtypes and multiple genetic mutations in its etiology.

Lung cancer is one of the most common solid organ tumors and is the leading cause of cancer-related deaths in the world. Approximately 1.8 million patients are diagnosed with lung cancer each year. (Lung cancer remains the most common cause of cancer-related deaths, responsible for 1 out of every 4 cancer-related deaths). When looking at these data, it is seen that every three minutes, one person is diagnosed with lung cancer, while another dies due to this disease.

Cancer in the lungs occurs when abnormal cells proliferate uncontrollably. Lung cancer often begins to develop from a single focus in a lung; however, it may also be caused by multiple focuses. Cancer cells can spread to the lungs, adjacent tissues, or other parts of the body. Lung cancer mostly metastasizes to lymph nodes, liver, central nervous system (brain), bones, and adrenal glands. Lung cancer can also metastasize to different lobes or to the other lung.

Basically, it can be classified into two groups as small cell lung cancer and non-small cell lung cancer. The most common symptoms are persistent cough, weight loss, hemoptysis, shortness of breath, and chest pain.



- Smoking

- Occupational exposure (contact with asbestos)

- History of radiation contact

- Genetic predisposition

- Nutrition

- Previous lung diseases


It is calculated that 80-90% of lung cancer mortality in men and 75-80% in women is caused by smoking. With 30 packs/year of smoking, the risk of death due to lung cancer increases 20-60 times in men and 14-20 times in women. Starting smoking before the age of 15 doubles the risk. The number of cigarettes smoked per day leads to a linear increase in risk. The prolongation of the smoking period leads to an exponential increase in risk.



Surgery, chemotherapy, radiotherapy, targeted drug therapy, and/or palliative therapy can be applied alone or in combination in the treatment of lung cancer. Factors affecting the treatment decision are the stage of the disease, the patient's performance status, the histopathological type of the tumor, and the mutation analysis.


While lung cancer was a rare disease at the beginning of the century, it has become the most fatal type of cancer in the world today. As Roche Turkey, we have prepared two awareness campaigns for the Lung Cancer Awareness Month in 2018 and 2019 with the slogan of “Bak Ciğerim, Akciğerim” (My Dear Lung).
