What are the early symptoms of lung cancer

summary

Not long ago, a family with almost all family members smoking came downstairs. After secretly observing the family, we found that one of them began to cough frequently, with blood in his sputum and chest pain, and got lung cancer. Now let's talk about the early symptoms of lung cancer.

What are the early symptoms of lung cancer

First, early lung cancer rarely fever, but when the cancer tissue necrosis, can cause low, moderate fever, antibiotic treatment is ineffective. When the central lung cancer with lesions close to the hilum of lung grows in the bronchus and develops to obstruction or semi obstruction of the lumen, it can cause obstructive pneumonia and cause fever all over the body. At this time, the body temperature is generally about 38'c. antibiotic treatment can reduce the fever, but if the obstruction is not removed, pneumonia can occur repeatedly.

Second: the pain is mainly in the large joint, mostly in the musculoskeletal joint, and then in the wrist joint. There is no wandering, which has nothing to do with the weather changes. Local swelling may occur. In addition to occasional periosteal thickening, X-ray pictures show no other abnormalities. Some patients may have rod-shaped finger (toe) performance. Clinically, these symptoms are called pulmonary osteoarthritis or ectopic growth hormone syndrome. Taking anti rheumatic analgesics can not improve the whole course of the disease, and once the focus of the lung is removed, the symptoms of joint pain will disappear.

Third: hemoptysis or bloody sputum is caused by capillary rupture caused by necrosis and ulceration of cancer tissue. The amount and duration of hemoptysis are related to the degree of vascular injury in cancer tissue. Most of them are persistent, with blood or small blood clots in the sputum, and the blood is bright red or dark red, which is not easy to control in general treatment. Hemoptysis or blood sputum blood is generally less, in a few cases, cancer erosion of large blood vessels, can cause massive hemoptysis.

matters needing attention

Most patients with lung cancer have the habit of smoking, so doctors will tell patients to quit smoking immediately to prevent the disease from worsening. Of course, it can not be ruled out that some patients are caused by inhalation of toxic gas due to work. In this case, doctors will advise patients to stay away from these places with exhaust gas and toxic gas.
