Clinical manifestations of breast cancer metastasis to lungs are related to the site and degree of metastasis, mainly including cough, hemoptysis, chest pain, pleural effusion and other symptoms.
1. Early stage of lung metastasis: there are often no obvious symptoms and signs, and lung nodules can be found only in chest CT and other imaging examinations.
2. Invasion of lung tissue and bronchial tubes: it can lead to symptoms such as dry cough and blood in sputum, hemoptysis if the cancerous lesion invades the bronchial blood vessels, and wheezing and shortness of breath if the cancerous lesion grows into the trachea and leads to partial obstruction of the trachea.
3. Invasion of pleura: it can lead to chest pain and symptoms such as chest tightness and shortness of breath after pleural effusion.
4. Widespread metastasis in the lungs: it may affect the respiratory function and cause symptoms such as chest tightness, shortness of breath and other respiratory difficulties.
5. Compression of surrounding tissues: if the cancer foci compress the recurrent laryngeal nerve, hoarseness may occur, and compression of esophagus may cause difficulty in swallowing.
If breast cancer patients have the above symptoms of lung metastasis, they should consult doctor for examination in time, and if diagnosed with lung metastasis, they should follow doctor’s instruction for treatment.
