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

Lung cancer develops very quickly. When some obvious symptoms are found, it is usually in the middle or late stage, and it is difficult to cure. Therefore, it is extremely necessary to grasp the early symptoms of lung cancer. If lung cancer can be discovered and treated early, the possibility of cure is still very high. Let's take a look at some of the early symptoms of lung cancer.

First, coughing up blood. Coughing up blood is one of the manifestations of lung cancer in the early stages of development. A medical institution counted 300 cases and found that 40% of lung cancer patients first had symptoms of coughing up blood, which was manifested in sudden coughing up blood for no reason or blood in the sputum. However, not all coughing up blood is lung cancer, it may also be caused by the rupture of capillaries in the nostrils. However, no matter what, it is always right to be cautious.

Second, Gu hammer finger. The so-called Gu hammer finger means that the first joint of the fingers and toes is swollen, the nails are bent, and there is occasional pain. Foreign surveys show that 18% of cancer patients have this symptom, which disappears after surgery to separate the tumor.

Third, joint inflammation. In fact, drumstick finger is also a kind of joint inflammation. Joint inflammation is mainly manifested in sudden pain in elbows, knees, wrists, palms and other joints, which is very inconvenient to move and lasts for a long time. Joint hyperplasia may occur in the later stage. After lung cancer surgery, the pain will disappear. Therefore, if your joints hurt for no reason in life, you must be vigilant and go to the hospital for examination if necessary. About one-third of lung cancer patients have extrapulmonary symptoms at the beginning, that is, very stubborn arthritis, cervical spondylitis, frozen shoulder, etc. However, because it is not caused in the lungs, no matter how it is treated, it is only a temporary solution and not a cure.

Why does lung cancer cause joint inflammation? Some analysts believe that this is because lung cancer cells can affect the secretion of growth hormone during the differentiation process, so a large amount of growth hormone will accumulate, stimulate joint hyperplasia, and cause swelling and pain.

Fourth, systemic myositis. According to statistics from relevant departments, 70% of lung cancer patients feel weak and have no appetite before the obvious symptoms of lung cancer appear, and some even have difficulty in moving.

Fifth, other symptoms. For example, listen to see if the voice is hoarse or wheezing, see if there is swelling on one side of the neck, see if the eyelids are drooping, etc. These symptoms are likely to appear before the lung symptoms are obvious.
