As we all know, lung cancer is a tumor that grows in the lungs, also known as primary bronchial lung cancer. The global morbidity rate is extremely high, and the mortality rate is increasing year by year. Many factors can lead to the occurrence of lung cancer.
What Are Some Common Early Symptoms Of Lung Cancer?
The following is for you:
Common early symptoms of lung cancer include:
(1) The cough is mostly occasional dry cough with little or no sputum, and there may be a small amount of white foamy sputum, which is more common after overwork. The cough time is not fixed and has nothing to do with body position.
(2) Hemoptysis or bloody sputum is caused by capillary rupture caused by cancer tissue necrosis and ulcers. The amount of sputum and the duration of hemoptysis are related to the degree of vascular damage in cancer tissue. Most of them are persistent, with blood stains or small blood clots in the sputum, and bright red or dark red blood, which are difficult to control in general treatment. Hemoptysis or bloody sputum is generally less blood. In rare cases, cancer corrodes large blood vessels and causes massive hemoptysis
(3) Chest pain Chest pain mostly occurs in the middle and advanced stages of lung cancer, but if the cancer is located near the pleura, chest pain may occur earlier, manifested as irregular dull pain or dull pain. When cancer directly invades the pleura, it may cause acute chest pain, cough or It gets worse when you breathe.
(4) Fever is rarely seen in the early stage of febrile lung cancer, but when the cancer tissue is necrotic, it can cause low-grade or moderate fever, and antibiotic treatment is ineffective. When the central lung cancer with the focus located near the hilum develops into bronchial lumen obstruction or semi - occlusion , can lead to obstructive pneumonia and systemic fever. At this time, the body temperature is generally around 38 degrees Celsius. Antibiotic treatment can reduce fever. However, pneumonia recurs if the obstructing lesion is resected.
(5) Joint swelling and pain mainly occur in large joints, mainly technetium joints, followed by wrist joints, inability to move, not related to weather changes, local swelling may occur, X-ray photos show that except for occasional periosteal thickening, there is no Other abnormalities Some patients may have rod fingers (toes). Clinically, these symptoms are called pulmonary osteoarthropathy or ectopic growth hormone syndrome. Taking antirheumatic painkillers does not improve the whole course of the disease, and once the lung lesions are removed, the symptoms of joint pain will disappear.
(6) Skin changes Few people will have skin swelling and itching rash, dermatomyositis, herpes zoster and so on. in the early stages.
(7) Progressive muscle weakness, muscle atrophy, diabetes, lower extremity edema, male breast enlargement, testicular atrophy, etc. It can also be seen in a small number of patients with endocrine system disorders. About one-third of early-stage lung cancer patients have no symptoms, and some patients have mild early symptoms, but they are not taken seriously or misdiagnosed, thereby delaying the progression of the disease. Therefore, in order to detect early lung cancer patients, it is necessary to conduct large-scale population censuses regularly, especially for factories, mines and cities with high incidence rates , which should be conducted once a year.
For patients over the age of 40,
(1) Unexplained chest pain, hemoptysis, and sputum, which are ineffective after treatment;
(2) Inflammation occurs repeatedly in the same part of the lung, and the effect is not good after active anti-inflammatory treatment;
(3) Patients with pulmonary tuberculosis who are stable after treatment and suddenly relapse and worsen, with inflammatory infiltration in a certain segment or lobe of the lung, local emphysema or atelectasis should be highly vigilant and should be further checked.
I believe that after reading the above content, you should have a preliminary understanding of the common early symptoms of lung cancer. Once lung cancer occurs, it will not only have a serious impact on our own health , but also worry our family members. Therefore, we should do a good job in early prevention, treatment and rehabilitation as soon as possible.
