Be alert, observe more during the incubation period of lung cancer

Lung cancer is caused by a variety of factors, so the symptoms of lung cancer are also various, and different types of lung cancer have different symptoms. What everyone does not know is that lung cancer also has a latent period, so the symptoms of lung cancer in the latent period are also very important.

1. Hoarseness

Lung cancer metastasis compresses the recurrent laryngeal nerve, which can paralyze the vocal cord muscles and cause hoarseness. Since lung cancer metastasis can appear in the early stage, and metastasis sometimes grows faster than the primary lesion, the clinical manifestation of metastasis can appear before the primary lesion. This is a common symptom of lung cancer in the latent period.

2. Neurological symptoms

Lung cancer brain metastasis may cause headache, vomiting, sudden coma, aphasia, hemiplegia and other neurological symptoms. Because the lung symptoms are not obvious, they are often misdiagnosed as thrombosis and brain tumors. We must be careful about these symptoms because they are all symptoms of the latent stage of lung cancer.

3. Male breast enlargement

About 10%-20% of patients experience breast hypertrophy, some with unilateral hypertrophy, but most with bilateral hypertrophy, and this symptom appears about a year earlier than lung symptoms such as cough, blood in sputum, chest pain, and shortness of breath. This is because some lung cancer cells can secrete chorionic gonadotropin, which can cause breast tissue hyperplasia and breast hypertrophy. Everyone must be careful of this latent symptom of lung cancer because it is easy to be ignored.

If you experience the above symptoms of latent lung cancer, you must go to the hospital for examination and treatment as soon as possible, and never misdiagnose. If patients want to know more about the symptoms of latent lung cancer, please click on our online expert.
