Many people always like to ask this question, is there any warning sign before getting lung cancer? Are there any special signs in the human body that can indicate lung cancer? In fact, lung cancer occurs early and hardly has any symptoms, so it is even less likely that there will be any special signs and warning signs before developing lung cancer.
There are 4 manifestations in the head, which may be a signal of lung cancer, but generally lung cancer is advanced.
1. Unilateral eyelid drooping
When one eyelid cannot be lifted for unknown reasons, beware of diseases that may be bad. The tip of the lung is an important sympathetic plexus in the body that needs to pass through, when the lesion is at the tip of the lung, it will cause the sympathetic nerve to be compressed, the most typical symptom is the ipsilateral eyelid drooping, pupil reduction. This symptom is clinically known as Horner syndrome and is typical of lung cancer at the apex of the lungs. It is called a suprachia. Some patients not only have droopy upper eyelids, smaller eye fissures, and narrow pupils, but also feel that half of the body is not sweating, and the shoulder and upper limbs on the affected side are painful.
Edema of the head and neck
When the head and neck are puffy, varicose veins, cyanosis on the face, and breathing is not smooth, it means that the condition has been more serious. These symptoms indicate compression of the superior vena cava and poor blood return to the cephalofacial veins, a technical term called superior vena cava syndrome. In fact, superior vena cava syndrome is not specific to lung cancer, and can occur as long as the malignant tumor metastase compresses the superior vena cava. Lung cancer is relatively common, and there are more small cell lung cancers.
headache
Headaches are very atypical symptoms because there are so many causes of headaches. For example, stroke, neurovascular headache, hypertension, carotid artery thrombosis, etc. may cause headaches. Headaches associated with lung cancer often appear in patients with brain metastases, and when brain metastases compress brain tissue, causing cerebral edema and increased intracranial pressure, headache symptoms will occur, and some will be accompanied by squirted vomiting.
Blurred vision
It is relatively rare for lung cancer patients to have simple blurred vision, but if lung cancer has brain metastases and compresses the optic nerve, it is possible that the vision is blurred, and generally there will be symptoms of headache and vomiting at the same time.
When the above four conditions occur in the head, it may be a manifestation of lung cancer, but these symptoms are not specific, and may be caused by other benign diseases or other cancers. And it often means that the malignancy is advanced, and the condition is more serious. Therefore, before suffering from lung cancer, it is unrealistic to expect the body to send out any early warning signals, the most important thing is targeted anti-cancer screening, for high-risk groups of lung cancer, physical examination once a year, do chest low-dose spiral CT.
It is worth mentioning that if you are a healthy person, just for the physical examination and screening of lung cancer, it is enough to do chest CT scan, there is no need to draw blood to check tumor markers, lung cancer antibodies seven items, there is no need to do peripheral blood circulation tumor cell detection, and it is not necessary to enhance chest CT, PET-CT and other examinations.
