Is small cell lung cancer serious?

Is the harm of small cell lung cancer serious? Many people have never heard of small cell lung cancer, but when it comes to the topic of cancer, everyone is very afraid, worried that cancer will bring their lives to an end. But what are the harms of small cell lung cancer? Let's learn about it together!

Causes: Smoking is the main risk factor for lung cancer, and SCLC is closely related to smoking. According to a summary analysis of smoking and lung cancer worldwide from 1970 to 1999, lung cancer is positively correlated with smoking intensity, amount and duration, and the relationship with SCLC is most obvious.

Pathogenesis: In the past few decades, there have been many studies on the molecular mechanism of SCLC, suggesting that the occurrence of SCLC may involve the involvement of multiple genes. Some studies have shown that the tumor suppressor gene p53, RB gene, neuroblastoma gene, oncogene Bcl-2 gene, Myc gene, PI3K, AKT, mTOR signal transduction pathway, etc. are all related to the occurrence of SCLC.

Small cell lung cancer risks:

1. It can cause tracheal obstruction in the patient, the disappearance of normal alveolar sac cavities, and affect the exchange of oxygen and carbon dioxide. The patient will feel chest tightness and shortness of breath.

2. Cancer can also make the patient unable to exclude bacteria, leading to pneumonia and fever. This type of pneumonia is called obstructive pneumonia.

3. Chest pain is one of the more common hazards of lung cancer. Pleural effusion may also occur. Excessive pleural effusion compresses the lungs, making it more difficult for the patient to breathe, and is quite difficult to treat.

4. If the lung tumor occupies a large part of lung cancer, it will seriously threaten the patient's breathing.

5. The occurrence of lung cancer seriously threatens the patient's life.

6. The nerves in the bronchi are quite sensitive. Cancer can irritate the bronchi, causing the patient to cough. If the condition persists for a long time, the patient may also develop symptoms of coughing up blood.

Choose environmentally friendly decoration materials. Eat balanced nutrition, eat more grains, vegetables, and fruits.
