Systemic symptoms of tumor metastasis

summary

Lung cancer metastasis is a very common clinical phenomenon, which is also one of the important causes of death of lung cancer patients. The ways of lung cancer metastasis include direct invasion, lymphatic metastasis, blood metastasis, etc. What are the symptoms of lung cancer brain metastasis? Let's talk about it.

Systemic symptoms of tumor metastasis

1. Headache is the most common symptom, and vomiting often occurs when headache is intense, characterized by jet vomiting; 2. Visual impairment indicates that the tumor has affected or invaded the optic nerve.

3. In addition to the above common symptoms, brain metastasis of lung cancer can also appear recurrence, paroxysmal amaurosis, sudden collapse, disturbance of consciousness, high blood pressure, slow pulse, severe cases can produce brain hernia due to tumor compression, leading to respiratory arrest, endangering the life of patients.

In addition, in recent years, due to the widespread application of brain CT examination in lung cancer patients, many asymptomatic patients with brain metastases have been found, which has won time for treatment. Therefore, brain CT should be regarded as routine examination in patients with lung cancer, in order to find brain metastasis as soon as possible.

matters needing attention

Radiotherapy is an effective method to treat brain metastases of lung cancer. CyberKnife is an advanced stereotactic radiotherapy method, which only needs 1-5 times of irradiation to kill tumor tissue. Due to the extremely accurate positioning of CyberKnife, there is no need to implant a stent in the patient's head for the treatment of brain tumors. The trauma of treatment is very small, and the most important thing is its good curative effect.
