Pulmonary symptoms of lung cancer
Cancer of the typical symptoms of cough, bloody sputum, chest pain, shortness of breath and other pulmonary manifestations. However, according to statistics, about half of lung cancer is initially expressed in pulmonary symptoms, and often the first symptoms in the lungs, as early signs of lung cancer. This situation can easily be misdiagnosed as other diseases delay in diagnosis and treatment. Common form of lung pulmonary symptoms include:
(1) neuromuscular syndrome, such as spinal cerebellar degeneration, peripheral neuropathy, a class of myasthenia gravis (muscle Yuan-li syndrome), and myopathy, etc., often misdiagnosed as other neurological diseases or dermatomyositis, more common in small cell lung cancer .
(2) hypertrophic pulmonary osteoarthropathy, multiple violations of the lower extremity distal Switzerland. Place-like fingers (toes) and hypertrophic osteoarthropathy, such as knee swelling, pain. Some patients the signs occur quickly, may be associated with the tip of finger pain, a bed surrounded by flush characteristics, more common in lung squamous cell carcinoma misdiagnosed as rheumatoid arthritis.
(3), nephrotic syndrome, skin and muscle disease such as myositis – dermatomyositis and systemic lupus erythematosus, acanthosis nigricans, also more common in squamous cell carcinoma.
(4) ectopic hormone syndrome, as manifested as muscle weakness, edema, hypertension, elevated urine Cushing's syndrome (small cell lung cancer more common), or nausea, vomiting, fatigue, sleepiness, directional Force disorders, abnormal secretion of antidiuretic hormone due to low sales or hypercalcemia (lung squamous cell carcinoma more common.)
(5), pulmonary symptoms of lung cancer electrolyte disorders, such as low pot, low-Yu syndrome, squamous cell carcinoma more common.
Therefore, when these patients but have not found the cause illness or treatment is poor, it is timely for the chest radiograph or chest CT to exclude lung cancer.
