What are the most easily ignored symptoms of lung cancer? 7 symptoms of lung cancer that are not easy to detect

Blood in sputum, mostly bloody sputum. Chest tightness, chest pain, shortness of breath, pneumonia caused by cancer obstruction, atelectasis, malignant pleural effusion, diffuse alveolar lesions, etc. can all be caused. This is also one of the symptoms of lung cancer.

About one-third of lung cancer patients do not have corresponding symptoms in the early stages even if they have lesions in the lungs. Experts point out that, especially for careless lung cancer patients, even if symptoms of lung cancer appear, they are easily ignored. Therefore, if you want to cure lung cancer, you must first discover the fact that you have lung cancer in the early stages.

There are many symptoms of lung cancer, but they are easy to be ignored. Common symptoms in daily life are:

1. There is blood in the sputum, mostly blood-streaked sputum.

2. Chest tightness and pain;

3. Shortness of breath, which can be caused by pneumonia, atelectasis, malignant pleural effusion, diffuse alveolar lesions, etc. caused by cancer obstruction. This is also one of the symptoms of lung cancer.

4. Caused by fever, obstructive pneumonia or cancer toxins.

5. Late-stage patients may develop more obvious cachexia

6. Cough. Since tumors mostly grow on large bronchi and are highly irritating, coughing is easy to occur. However, the degree of cough varies. About 50% of patients have irritating coughs, no sputum or a little white foamy sputum. After secondary infection, the quality of sputum also changes. If the original chronic cough is found to be different from usual, it should be alert. Patients of high-risk age should see a doctor as soon as possible when the cough is ineffective after treatment or lasts for a long time. Those with hemoptysis should see a doctor early.

7. Hoarseness can occur after pharyngitis, colds, acute bronchitis, thyroid surgery, pharyngeal surgery, improper vocalization, excessive talking, or even heavy smoking and drinking. However, this type of hoarseness can generally be treated symptomatically or healed by rest. Hoarseness caused by lung cancer, thyroid cancer, and laryngeal cancer is completely different from the above hoarseness, especially lung cancer.

Experts remind: Although regular examinations may not be able to accurately detect lung cancer, it will be even more difficult to detect early lung cancer if the patient does not undergo any examinations. Moreover, some lung cancer patients already have other lung diseases in the early stages, but they only develop lung cancer because they did not seek treatment. This is very regrettable.
