Is small cell lung cancer serious? Two knowledge points reveal the dangers of small cell lung cancer

Small cell lung cancer is a highly malignant lung tumor that is characterized by recurrent attacks. It is relatively serious and can affect respiratory function and be life-threatening in severe cases.

1. Impact on respiratory function <br/>Small cell carcinoma affects the normal respiratory function of the lungs. When the tumor is large, it can block the bronchi and prevent normal gas exchange. It causes symptoms such as chest tightness, shortness of breath, and difficulty breathing. Some patients may even experience temporary respiratory failure.
2. Life-threatening <br/>Small cell carcinoma develops rapidly and can develop into the middle or late stage in a short period of time. Cancer cells can metastasize to important organs and tissues such as the brain, liver, and kidneys through blood and lymphocytes, inducing local lesions. If not treated in time, the patient may experience organ failure in various parts of the body within 3 to 6 months of onset. Surgery, radiotherapy, chemotherapy and other treatment methods have a poor prognosis and are life-threatening.
