What are the early symptoms of lung cancer? There are 7 common manifestations of early lung cancer

The earlier most diseases are treated, the easier they are to cure. The same is true for lung cancer. If measures are taken to control the progression of lung cancer in its early stages, the chances of cure will increase. However, if treatment is delayed until the late stages, cure will become much more difficult. Now let's talk about the early symptoms of lung cancer.

Common early symptoms of lung cancer include:

1. Chest pain Chest pain mostly occurs in the middle and late stages of lung cancer, but if the tumor is located near the pleura, chest pain may occur earlier, manifesting as irregular dull pain or dull pain. When the tumor directly invades the pleura, there may be sharp chest pain, which worsens when coughing or breathing.

2. Fever. Lung cancer rarely causes fever in the early stage, but when the cancerous tissue is necrotic, it can cause low or moderate fever, and antibiotic treatment is ineffective. When the central lung cancer with lesions close to the hilum of the lung grows in the bronchus and develops to the point of obstruction or semi-obstruction of the lumen, it can cause obstructive pneumonia and systemic fever. At this time, the body temperature is generally around 38'C. Antibiotic treatment can reduce the fever, but if the obstructive lesions are not removed, pneumonia can recur.

3. Joint swelling and pain. The pain mainly occurs in large joints, mostly in the iliac joints, followed by the wrist joints. It is not migratory and has nothing to do with weather changes. Local swelling may occur. X-rays show no other abnormalities except for occasional thickening of the periosteum. Some patients may have rod-shaped fingers (toes). Clinically, these symptoms are called pulmonary osteoarthritis or ectopic growth hormone syndrome. Taking anti-rheumatic analgesics does not improve the entire course of the disease, and once the lesions in the lungs are removed, the symptoms of joint pain will disappear.

4. Skin changes: A small number of people may show itchy skin rashes, dermatomyositis, herpes zoster, etc. in the early stages.

5. Endocrine system disorders: A small number of patients may also experience progressive muscle weakness, muscle atrophy, diabetes, lower limb edema, male breast enlargement, testicular atrophy, etc.

6. Coughs are mostly occasional dry coughs with little or no sputum, and may contain a small amount of white foamy sputum, which often occurs after fatigue. The coughing time is not fixed and has nothing to do with body position.

7. Hemoptysis or bloody sputum is caused by rupture of capillaries due to necrosis and ulceration of cancerous tissue. The amount of hemoptysis and the duration of hemoptysis are related to the degree of vascular damage in the cancerous tissue. It is usually persistent, with blood streaks or small blood clots in the sputum, and the blood is bright red or dark red. It is generally difficult to control with treatment. Hemoptysis or bloody sputum usually contains less blood. In a few cases, cancer erodes large blood vessels, which can cause massive hemoptysis.
