Do you know the early symptoms of lung cancer? Pay attention to the six early symptoms of lung cancer

Lung cancer is now a very common disease in life. If you don’t know much about the early symptoms of lung cancer, it is easy to create opportunities for the occurrence and development of lung cancer. Therefore, in order to ensure our health, we should pay attention to the common symptoms of lung cancer. The following is an introduction to the early symptoms of lung cancer:

1. Nasal congestion: Unilateral nasal congestion occurs due to the tumor blocking the posterior nostril. In the late stage, due to the enlargement of the tumor, nasal congestion occurs on both sides.

2. Nosebleed: It is one of the early symptoms of nasopharyngeal cancer. Most of them are a small amount of mucus or blood stained mucus blown out from one nostril. Most patients suck out the bloody mucus from the oropharynx by retracting the nasal cavity. This "pharyngeal" nosebleed causes missed diagnosis and misdiagnosis. In the late stage, cancer erosion of blood vessels can cause heavy bleeding.

3. Tinnitus and hearing loss: Tumors blocking or compressing the pharyngeal opening of the Eustachian tube can cause tinnitus, stuffy ears and hearing loss on the same side, or be accompanied by tympanic effusion.

4. Headache: It is often caused by tumors destroying the skull base, spreading inside the skull or affecting cranial nerves. In the late stage, the persistent and severe headache in a fixed location can be easily mistaken for neuralgia.

5. Neck lumps: According to statistics, the neck metastasis rate of nasopharyngeal carcinoma is 40% to 85%, and about half of the patients seek medical treatment for neck lumps. Because the nasopharynx is rich in lymphatic tissue, cancer cells can easily metastasize to the upper group of deep cervical lymph nodes, and later develop to the middle group, lower group or posterior group, and can develop to the opposite side. The number of neck metastatic lumps of nasopharyngeal carcinoma is small, it grows rapidly, is hard and painless, has poor mobility, and is fixed due to adhesion and fusion in the late stage.

6. Blood in sputum. When tumor inflammation causes necrosis and capillary damage, there will be a small amount of bleeding, which is often mixed with sputum and appears intermittently or intermittently. It is also a common early symptom of lung cancer. Many lung cancer patients seek medical treatment because of blood in sputum.

This is an introduction to the early symptoms of lung cancer. Lung cancer is very threatening. Therefore, if you want to completely cure lung cancer, early detection is very critical. Therefore, it is necessary for us to understand the early symptoms of lung cancer in our lives. Only by paying attention to changes in ourselves at all times can we detect the disease early.
