Does brain cancer cause ear pain?

In the situation described, if there is a brain tumor, compression of nerves in the later stage does not rule out ear pain and hearing loss or vision loss, because brain tumors in the central part of the brain will compress nerves and cause systemic symptoms. It is recommended to go to the hospital for a brain examination in time. The nerve distribution of brain tissue is very complex, including sensory and olfactory nerves. If the location of the brain tumor is special, it may also cause ear pain symptoms if it only compresses the nerves around the ear. Intracranial malignant tumors, if they grow in functional areas, can cause symptoms such as increased intracranial pressure.

Why did a brain tumor metastasize to the lungs without any previous symptoms?

Once lung adenocarcinoma metastasizes to the brain, it means that the lesion has reached stage IV. During this period, the chance of radical surgery is lost, and its treatment methods are mainly targeted therapy and chemotherapy. Symptoms and signs of lung cancer metastasis to the chest can be seen in 3% to 10% of patients, mostly small cell lung cancer, followed by undifferentiated large cell lung cancer, adenocarcinoma and squamous cell adenocarcinoma. Brain tumors with lung metastasis are mainly treated with drug chemotherapy.

Can a patient in a coma with advanced brain tumor wake up?

The patient's coma means that it has reached the late stage. As for this period, the most important thing is to prolong the patient's life and improve the patient's quality of life. If forced surgery is performed, the patient's survival time may be shorter. If the brain tumor patient has reached the late stage, there is a high probability of mass effect. In this case, if a coma is induced, the probability of waking up is very small. As a family member, you must do a good job of care and keep the patient's airway open. Late-stage intracranial malignant tumors often cause severe increase in intracranial pressure.
