Screening for Lung Cancer Risk

Screening for Lung Cancer risk. The faster it is detected Increasing the chance of surviving.

Lung cancer is still a major health problem and is the number one cause of death in the world. Since 1950, lung cancer is the most common cancer in the world. Until 2015, the same incidence of lung cancer killed more patients than breast, prostate, and colon cancer combined. The incidence of 5-year survival of lung cancer is only 16.8% because it is often detected in lung cancer in the later stages.

The reason that lung cancer is still the number one cause of death. In addition to carcinogenic risk factors, such as direct and indirect smoking or exposure to heavy chemicals from work, such as chromium, Nickel S-base (Asbestos) and others, another important factor is The ability to screen for this disease.

Many patients that regularly check-up But can not screening for cancer at an early stage Maybe it’s because the health examination is wide. Which may not be sufficiently detailed Or may be caused by the patient to check when the symptoms are symptoms, such as coughing or tired, which is often found in later lung cancer. Causing the chance of survival to be quite low

Therefore, in 2011, the international research association of lung cancer. (International association for the study of lung cancer: IASLC) conducted a comparative study between chest x-ray and low dose computing tomography chest screening (LDCT) in the group. Population at risk Found that computer tomography (LDCT) can find lung cancer better than normal x-ray (rate ratio 1.13: 95% confidence interval, 1.03 to 1.23) and can also reduce the incidence of damage Lives from lung cancer in people at risk up to 20 percent

The advantages of low dose computing (LDCT) are:

  • For clear, detailed images Can see the picture in many ways through the body
  • The amount of radiation is 5 times less than that of a normal CT chest (equivalent to 15 normal x-rays).
  • Takes less than 1 minute
  • No color injection
  • Do not need to check kidney fees
  • Radiation levels will come down to normal within 6 months.

The suggestion of the research is people at risk of lung cancer, an X-ray computerized lung (LDCT) should be performed once a year up to the age of 79 and normal lung x-rays are not recommended for lung cancer screening.

High risk group has 2 groups as follows

  • Group 1
    1. 55-74 years old
    2. Smoking Or have ever smoked an average duration of more than 30 years and more than 1 pack per day or 30 pack-year, for example
      • Smoker for 15 years, average 2 packs per day
      • Smoker for 20 years, on average a pack of half a day
      • Smoker for 30 years, average 1 pack per day
    3. Stop smoking for no more than 15 years
  • Group 2
    1. Over 50 years old
    2. Smoking Or have ever smoked an average duration of more than 20 years and more than 1 pack per day or 20 pack-year, for example
      • Smoker for 10 years, average 2 packs per day
      • Smoker for 20 years, average 1 pack per day
    3. There are other risks, such as having a family history of cancer. Or receiving chemicals such as asbestos or nickel and chrome etc.

Interested in screening for lung cancer with X-ray computer (Low dose Computed tomography chest screening (LDCT). “Because health is important The faster it is detected Increasing the chance of survival. “
