What are the early symptoms of lung cancer? Four common early symptoms of lung cancer

It manifests as hypertrophy of the first joints of the fingers and toes, protrusions and bending of the nails, and is often accompanied by pain. According to foreign reports, 21% of lung cancer patients have clubbing in the early stages, and most of them disappear after lung cancer surgery. Arthritis often coexists with clubbing, and can occur when the lung cancer lesion is very small.

In addition to smoking, environmental factors are also a major cause of lung cancer. Experts point out that lung cancer is also an occupational disease, so if you work in an environment containing a large amount of carcinogens, you must take relevant preventive measures, pay more attention to the early symptoms of lung cancer, and seek treatment as soon as possible.

Generally speaking, early lung cancer often has the following four signs:

1. Clubbing

It manifests as hypertrophy of the first joints of the fingers and toes, protrusions and bending of the nails, often accompanied by pain. According to foreign reports, 21% of lung cancer patients have clubbing in the early stage, and most of them disappear after lung cancer surgery. Arthritis often coexists with clubbing, and may first appear when the lung cancer lesions are very small and difficult to detect. It manifests as migratory arthritis symptoms, burning pain in the elbows, knees, ankles, metacarpophalangeal joints, movement disorders, possible edema and tibia and fibula periosteal hyperplasia, etc. The pain may disappear 24 hours after lung cancer surgery.

2. Male breasts become feminine

Male breasts become feminized, enlarged on one or both sides, or even become as plump as female breasts, which is often one of the early signs of lung cancer. A Japanese survey of 267 lung cancer patients found that 7.5% of them had gynecomastia in the early stage. Gynecomastia is often ignored, or even misdiagnosed as simple breast hyperplasia and removed.

3. Hemoptysis

It is one of the most common early symptoms of lung cancer. A study has counted 312 lung cancer patients and found that 40.9% of them first experienced this symptom. It is characterized by sudden hemoptysis of sputum in middle-aged and elderly people, or repeated blood in sputum, which is often misdiagnosed as bronchiectasis, bronchitis, pneumonia and other diseases.

4. Polymyositis

It is also one of the early symptoms of lung cancer. According to statistics, 85% of them appear before the typical symptoms of lung cancer, which are manifested as progressive weakness of the whole body, loss of appetite, difficulty walking and difficulty getting up from bed when the symptoms worsen. Other manifestations include hoarseness with wheezing for no obvious reason, obvious swelling of one side of the neck, fission of one eye, drooping eyelid, etc.

These symptoms occur in many lung cancer patients. Although the specific cause of lung cancer is still unclear, experts have studied and confirmed that nine industrial raw materials can cause lung cancer, so we must be careful. In addition, lung cancer patients should also pay more attention to their diet, so as to excrete possible cancer-causing toxins in the body.
