What are the misunderstandings in the diagnosis of lung cancer? Five misunderstandings should be avoided when diagnosing lung cancer

What are the misconceptions about lung cancer diagnosis? Lung cancer is a disease that is very harmful to people's health. Many patients do not know that they are ill after they are diagnosed with the disease. However, by the time they find out, the cancer has already reached the advanced stage. Therefore, everyone needs to understand some diagnostic methods for lung cancer. So, what are the misconceptions about lung cancer diagnosis?

1. Patients with nonspecific systemic skin, neurological, and endocrine manifestations, such as hypertrophic osteoarthropathy, clubbing of fingers (toes), myasthenia-like syndrome, etc.

2. People over 40 years old suddenly develop an irritating cough that lasts for more than 2 weeks and is ineffective with treatment. The nature of the cough changes for those who already have a cough.

3. High-risk groups, such as long-term smokers, industrial and mining workers, those who have long-term exposure to radioactive substances, and those with a family history of cancer, should be listed as the key population for lung cancer screening and should be examined once every six months to one year.

4. For patients with chronic cough, the cough turns into an irritating dry cough with blood in the sputum, obvious chest pain, or repeated pneumonia in a certain lobe or segment of the lung.

5. Patients with pulmonary tuberculosis who have not responded to regular anti-tuberculosis treatment, and whose X-rays show progressive enlargement of the lesion shadows, segmental pneumonia, atelectasis, and eccentric cavities.
