Cure rates drop dramatically as the tumor becomes more advanced and involves lymph nodes or other parts of the body. Screening with low-dose spiral computed tomography CT scan has been proven to reduce lung cancer deaths in people at high risk for lung cancer. In these individuals, the benefits of early detection outweigh the risks of potential false positives.
Lung cancer screening is recommended for people who meet these criteria:. At least a 30 pack-year smoking history 1 pack-year is the same as smoking 1 pack of cigarettes every day for an entire year. There are different kinds of lung cancer. This is the most common subtype of cancer, but also much more common in people who never smoked, younger patients, and women. Squamous cell cancer. This is more commonly linked to a history of smoking.
It develops in the airways of the lungs. Large cell carcinoma. Targeted therapies work. This type of cancer treatment is called targeted therapy. And, because there are new and emerging targets being found in research, it is reasonable to do wider testing to look for other mutations as well. Oral medicines for patients with some of mutations are highly effective; they can shrink tumors significantly, work for a long time, and provide people with lung cancer with a good quality of life.
Immunotherapy helps people with a broad range of lung cancers live longer. Immunotherapy is type of cancer treatment that works by boosting or activating your immune system, so it recognizes and kills cancer cells.
Researchers are investigating 4 main kinds of immunotherapies for lung cancer: checkpoint inhibitors, monoclonal antibodies, therapeutic vaccines, and adoptive cell therapy. For patients with tumors with high levels of a biomarker called PD-L1, pembrolizumab Keytruda works better than chemotherapy as a first therapy. For tumors with low or no expression of PD-L1, drugs such as atezolizumab Tecentriq and nivolumab Opdivo can be effective as second treatments. Tobacco smoke, carcinogens and lung cancer.

The diagnosis of the disease presently, similarly to earlier years, was determined in the advanced disease stages [ 2 , 9 ].
One of the main reasons for a late diagnosis of lung cancer in the patients under 40 was a wrong initial diagnosis. That misguided diagnosis rarely included tuberculosis, though there was fluid accumulation in the pleural cavity in the course of the disease. As compared to the previous years, the delays in diagnosis shortened considerably and the disease was diagnosed in about 2 months. This study is not an epidemiological, but a clinical work.
The presented data do not necessarily reflect the epidemiological situation in selected regions of Poland. In conclusions, adenocarcinoma is presently the predominant histological type among patients under 40 years old. Increasing lung cancer incidence is observed among young women under 40 years old, and the frequency of lung cancer is similar in men and women in this age group.
The time that passes from the first symptoms of the disease to lung cancer diagnosis is shorter in comparison with previous years. However, diagnosing early stage lung cancer is still very rare.

Material and methods The analysis included: sex, age, clinical symptoms found before and at the moment of diagnosis, character of changes visible in radiological imaging, time that passed from the first symptoms to reporting to a doctor and to establishing a diagnosis, type of diagnostic method used in establishing the final diagnosis, histopathologic type of cancer, degree of cancer progression.
Results The results have been compared with a peer group who had been diagnosed 20 years earlier. Keywords: lung carcinoma, young patients, sex, diagnosis. Introduction Lung cancer is one of the most common cancers in the world. Results The disease was diagnosed in 23 men and 19 women. Open in a separate window. Table 2 Clinical symptoms at diagnosis.
