Is lung cancer asymptomatic without metastasis?

summary

Lung cancer is the largest malignant tumor in China, and the mortality rate is also very high. The early cure rate of lung cancer is very high, but it is difficult to cure in the late stage, which poses a serious threat to life and health. After surgery, radiotherapy and chemotherapy, many patients are in the recovery period, and they are always worried about tumor metastasis. Is lung cancer asymptomatic without metastasis? Next, I'd like to share my views with you.

Is lung cancer asymptomatic without metastasis?

Lung cancer metastasis is divided into several aspects, there are blood line metastasis, there are lymph nodes, that is, through the lymphatic metastasis. There is also direct transfer. For example, our trachea and esophagus are adjacent organs, and some patients have difficulty swallowing. This is a direct (transfer).

There are also some implantation metastases. For example, our tumor grows in the pleura, which is close to the pleura. It has infiltrated into the pleura. It will be implanted into the pleura of layer B, and pleural effusion will appear. There are about four ways. It causes metastasis. For example, blood metastasis can be transferred to the brain and liver.

Lymphatic metastasis can pass through the lymph nodes, one station at a time, and it can also jump over. Some of our patients, such as our lung tumors, have the most common lymph node metastasis in hilar and mediastinum. Some patients have supraclavicular lymph node metastasis, but some patients can have jumping metastasis to axillary lymph nodes, Or metastases to the abdominal lymph nodes, probably in these four aspects.
