Why lung cancer is one of the most dangerous types of cancer?
Currently, lung cancer is classified as one of the most dangerous cancer types and has the second highest rate of incidences of all types of cancer as well as one of the highest mortality rates of all cancers. Moreover, it is the risk factor that causes this disease to increase in our daily lives.
Why lung cancer is dangerous?
Lung cancer is difficult to detect in the early stages because its expression is not clear and easily confused with other diseases of the respiratory tract.
In Vietnam, most lung cancer patients were detected at a late stage. Only about 10-20% of lung cancer patients are detected at an early stage. According to statistics, every year in Vietnam there are about 20,000 new people diagnosed with lung cancer while the mortality rate is up to 17,000 people per year.
Lung cancer accounts for 13% of all cancer cases but death rates from this disease are up to 28% of all deaths from cancer.
Lung cancer is considered the most dangerous disease in Vietnam because of its rapid development of the disease. In particular, small cell lung cancer has twice the growth speed and it is as fast as a non-small lung cancer cell which quickly metastases.

Lung cancer has a poor satisfactory prognosis than other types of cancer
Lung cancer is usually detected and diagnosed at a late stage and because of that the treatment process becomes more difficult than other types of cancer. Because lung cancer is most often diagnosed in the late stages, the prognosis of the patients is at a low level.
For non-small cell lung cancer: the statistics for a 5-year survival rate for stage 1A is 49%, 1B is 45%, 30% for 2A, 31% for 2B .The prognosis of stage 3 is 14% and 3B is only 5%. The average time for treatment is 13 months. The cases that are at stage 4(metastic): a 5-year survival rate is only 1% while the average survival time is about 8 months of treatment.
For small cell lung cancer: the survival rate is 5 years for both stages of this disease (limited stage and extended stage) that is only about 6%. If it is untreated, the average survival time is from 2 to 4 months, and with treatment 6 to 12 months.
How to diagnose Lung Cancer
Most lung cancer patients get examined when the body starts with symptoms of coughing, coughing up blood, body weakness, fatigue, rapid weight loss, shortness of breath, glands visible in the neck and armpit ...at that time, most of the cases have progressed into the later stages of the disease which leads to a lower prognosis. The patient's survival time after detection becomes very short.
Most patients were detected of the disease in the late stages
If patients are diagnosed with lung cancer, the doctor will assign a sputum cytology test (observing cell samples will be taken from lung mucus under a microscope). For an accurate diagnosis, the doctor must examine lung tissue.
After determining the exact status of the patient, the doctor will conduct more tests to distinguish phases and to know if cancer cells have spread to other parts of the body. Lung cancer usually affects the brain or bones. The determination of the exact stage will help doctors to plan the treatment regimen.
There are many patients diagnosed with lung cancer by taking X-rays when doing a cardiopulmonary for a periodic health examination. Getting an annual checkup with a lung X-ray should not be overlooked. To protect your health, you should be examined 1 to 2 times per year.
