K Hospital doctors guide prevention, early detection of lung cancer-Life Health

According to Doctor BV K, lung cancer screening to detect lung cancer in the early stages is very useful for treatment and reducing mortality.

In Vietnam, lung cancer is one of the most common cancers. This is one of the dangerous cancers and accounts for a high mortality rate, because it is often detected late, making it difficult to treat. Therefore, according to Assoc. Prof. Dr. Le Van Quang, Director of K Hospital, lung cancer screening to detect lung cancer in the early stages is very useful for treatment and reducing mortality. Lung cancer risk factors include:

Sex

Lung cancer predominates in men 50-75 years old. In Western countries, the rate of lung cancer in men in some countries has not increased in recent years, while the rate of lung cancer tends to increase in women.

Bronchopulmonary diseases

Lung cancer occurring on fibrous scars is a problem that has been discussed quite a lot. Fibrotic scars are usually caused by tuberculosis, pulmonary infarction, pneumonia, or pneumococcal disease. The pathogenesis of the disease is unknown, but it is thought that fibrosis obstructs the lymphatic vessels causing accumulation of carcinogens that may lead to cancer.

Air pollution: due to combustion in homes, factories, exhaust gases from engines.

Screening methods: Clinical examination, blood tests, low-dose computed tomography of the chest.

Low-dose chest computed tomography:

Lung cancer screening with low-dose tomography is a major advance in the field of cancer screening. This screening method with computer software supports accurate interpretation of captured images and reduces costs. The dose is set at 2mSv (compared to the standard dose of 7mSv), reducing the risk of radiation exposure compared with conventional chest computed tomography.

Recent research data show that, for patients at high risk of lung cancer, conducting early cancer screening with low-dose radiation tomography annually increases the number of cases by 20%. Lung cancer cases are detected when compared with conventional chest x-ray. Because of such obvious benefits, many current recommendations are suggesting that low-dose radiation chest computed tomography, conducted annually, is a good method for screening and early detection of lung cancer. .

The diagnostic test was considered positive when it detected noncalcified nodules 4 mm or more on low-dose computed tomography, and any non-calcified nodules on chest radiograph.

Preventive

Lung cancer prevention is mainly step 1 prevention.

Smoking is a major cause of lung cancer

Risk Carcinogenic Increases with smoking duration, passive smoking is also a risk factor. It is therefore necessary to:

Propagating the harmful effects of tobacco

+ Anti-smoking in public places

+ Advise current smokers to stop smoking.

+ Support for patients to stop smoking

+ Regular follow-up visits.
