Six small symptoms indicate lung cancer Some early symptoms of lung cancer are actually “distress signals” from the body. Six symptoms, such as cough, hemoptysis, chest pain, fever, pestle finger and arthritis, which seem to be unrelated to lung cancer, should not be taken lightly. 1. Cough may be a mild dry cough or a severe cough with varying amounts of sputum. People with long-term cough should be alert to lung cancer once the nature of cough changes, such as frequency change or irritating dry cough. 2.Hemoptysis Once smoking men over 40 years old have blood in sputum, blood or small blood clots, the possibility of lung cancer is quite high, which is also one of the early symptoms of lung cancer. 3. Chest pain Intermittent non-severe dull pain or drilling pain in the chest, which may last for several minutes to several hours. If the cancer invades the pleura, the pain will be more intense, persistent and fixed. 4.Fever Male smokers over 45 years old who have long-term chronic lung inflammation with fever and poor treatment results should be especially alert to the possibility of lung cancer. 5.Pestle and mortar finger, also known as pestle finger, is characterized by hypertrophy of the first joint of the finger and toe, with the nail protruding and becoming curved, often accompanied by pain. 6.Arthritis often exists together with pestle finger. The symptoms of arthritis include burning pain in elbow, knee, wrist, ankle and metacarpal joints, and obstruction of movement. Finally, it is reminded that once lung cancer is diagnosed, in order to achieve the best treatment effect, standardized pathological diagnosis should be made first, and the stage of the disease should be clarified, on which basis a multidisciplinary and comprehensive treatment plan should be formulated.
