What are the common extrapulmonary symptoms of lung cancer? Several extrapulmonary symptoms of lung cancer

About 10% of patients may experience such symptoms, which may appear as the first symptom. Some other patients may have no clinical symptoms, but one or more plasma ectopic hormones may be detected to be elevated. Such symptoms are more common in small cell lung cancer.

The occurrence of lung cancer is closely related to smoking. Once again, I would like to remind you that if you have the habit of smoking, it is best to quit smoking and keep yourself healthy. Here I will introduce several extrapulmonary symptoms of lung cancer for your reference:

1. Pulmonary osteoarthritis

Clinically, the main manifestations are tussock fingers (toes), periosteal hyperplasia at the distal end of long bones, new bone formation, swelling, pain and tenderness in the affected joints. The long bones are the tibia, humerus and metacarpal bones, and the joints are more common in large joints such as the knee, ankle and wrist. The incidence of tussock fingers and toes is about 29%, which is mainly seen in squamous cell carcinoma; the incidence of hyperplastic osteoarthritis is 1% to 10%, which is mainly seen in adenocarcinoma, and small cell carcinoma rarely has this manifestation. The exact cause is not yet fully understood, and it may be related to estrogen, growth hormone or nerve function. Surgical resection of the tumor can relieve or disappear, and it may recur when it recurs.

2. Ectopic hormone secretion syndrome associated with tumors

About 10% of patients may experience such symptoms, which may appear as the first symptom. Some other patients may have no clinical symptoms, but one or more plasma ectopic hormones may be detected to be elevated. Such symptoms are more common in small cell lung cancer.

Regarding lung cancer, I hope everyone will pay attention to what I mentioned above, and be sure to protect your living environment. After all, in addition to genetics, the most serious factor for lung cancer is your environment. If the environment is not good, the probability of developing lung cancer is still quite high, so everyone must pay attention.
