What are the symptoms of lung tumors? It turns out there are 7 types

Lung cancer is a disease with a relatively high incidence rate recently, which is mostly related to the recent decline in air quality. Therefore, it is particularly important to understand the symptoms of lung cancer and to achieve early detection and early treatment. So what are the symptoms of lung cancer? Let's learn about it together!

1. 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 duration of coughing is irregular and has nothing to do with body position.

2. Hemoptysis or bloody sputum is caused by rupture of capillaries due to necrosis and ulceration of cancerous tissue . The amount of hemoptysis and its duration are related to the degree of vascular damage in the cancer tissue. Most of the symptoms are 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. The amount of blood in hemoptysis or bloody sputum is generally small. In a few cases, tumors erode large blood vessels and cause massive hemoptysis.

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

4. Fever: Fever is rarely an early symptom of lung tumors, but when the cancerous tissue is necrotic, it can cause low or moderate fever, which is ineffective against antibiotic treatment. When 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 bronchial lumen, it can cause obstructive pneumonia and systemic fever. At this time, the body temperature is generally around 38°C and can be reduced by antibiotic treatment. However, if the obstructive lesions are not removed, pneumonia may recur.

5. Joint swelling and pain are mainly in the large joints , mostly the ankle joints, followed by the wrist joints. They are not migratory and have nothing to do with weather changes. Local swelling may occur, and X-rays usually show no other abnormalities except occasional thickening of the periosteum. Some patients may have clubbing of fingers and toes. Clinically, these symptoms are called pulmonary osteoarthropathy or ectopic growth hormone syndrome. Taking anti-rheumatic analgesics does not improve the overall course of the disease, but once the lesions in the lungs are removed, the symptoms of joint pain will disappear.

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

7. 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., which are also common early symptoms of lung tumors.
