Brain metastasis of lung cancer is caused by hematogenous spread of lung cancer to the brain. Brain metastasis typically presents with symptoms such as headaches, nausea, and vomiting, including projectile vomiting. The headaches may be severe, and there may be abnormalities in sensory perception and motor function, possibly accompanied by seizures, mental confusion, olfactory disturbances, visual impairments, and other symptoms. The specific symptoms can vary depending on the location of the metastasis in the brain. However, most patients experience headaches, nausea, and vomiting. Individual differences are significant, and it's important to analyze the specific issues and the specific areas of the brain affected.

How to treat dry cough caused by lung cancer?

Dry cough is a very common symptom in clinical practice, caused by many factors which are also very complex. Some patients might clearly have lung cancer. Due to the presence of lung cancer lesions, patients can experience irritating dry cough as well as symptoms like hemoptysis, chest pain, and chest tightness. It is possible that some patients do not exhibit symptoms of dry cough, perhaps due to other causes. Therefore, for dry cough, we need to identify if it is caused by lung cancer, as it often requires surgical treatment to control the symptoms. Some patients with minor lung cancer who experience dry cough might be able to control it with appropriate medications. However, to effectively control symptoms of dry cough caused by lung cancer, surgical removal is generally necessary and is the ultimate treatment plan.

Dietary therapy for lung cancer

In the diet of lung cancer patients, Western medicine does not have the concept of "trigger foods" like Chinese medicine does. According to Western medicine, there are no specific dietary restrictions; the focus is on maintaining a balanced diet as usual, incorporating meat, proteins, vegetables, and fruits to ensure nutritional balance. Generally, lung cancer patients may experience coughing symptoms, so it is advisable to consume a light diet avoiding oily fried foods. Extremely spicy foods can provoke irritative coughing and worsen it, so they should be avoided, along with barbecued and pickled foods, and junk food. Other than that, the diet should be similar to a normal balanced diet. For patients undergoing chemotherapy, a high-protein diet is recommended, preferably consisting of steamed or stewed dishes. These can be combined with traditional Chinese medicinal herbs such as Astragalus, American ginseng, and Dong quai, which are known to boost energy and enhance resistance, thus aiding in dietary therapy to strengthen the patient's immunity.

How to detect early symptoms of lung cancer?

So, the early symptoms of lung cancer often include a cough, hemoptysis, difficulty breathing, and chest pain. However, these symptoms, particularly the irritating cough, typically appear after the tumor has grown in the larger bronchi; this is often mistaken for a cough following a cold, leading to misdiagnosis or delayed treatment. Therefore, if this type of irritating cough occurs, it is essential to seek medical attention promptly and to undergo chest X-ray or CT scan. Second, as the tumor continues to grow and affects the drainage of the bronchus, secondary lung infections may occur, often characterized by coughing up pus-like sputum, and an increase in the amount of sputum, which should also be noted. Third, a very common symptom is the presence of blood in the sputum, or streaks of blood, or intermittent minor hemoptysis, which must be taken seriously.

What tests are conducted for lung cancer?

Diagnosis of Lung Cancer: The first method can be through chest X-ray and CT scan; The second is sputum cytology examination; The third involves using a bronchoscopy; The fourth is mediastinoscopy, which allows direct observation of the enlargement of lymph nodes on both sides of the mediastinum; The fifth is to perform PET-CT, which is Positron Emission Tomography-Computed Tomography; The sixth requires a biopsy; it can be done through a transthoracic needle biopsy, or via a bronchoscopic biopsy; The seventh is the biopsy of metastatic lesions, such as subclavian lymph nodes, and lymph node metastases in the neck or axillary areas can be examined; The eighth can involve drawing cancerous pleural effusion; if there is pleural effusion, pleural fluid cytology examination can be performed; The ninth method is thoracotomy exploration; if lung nodules or lung tumors cannot be definitively diagnosed through various other methods, thoracotomy exploration can be performed.

How long can one live with lung cancer?

The survival period of malignant tumors is a topic of great concern to everyone. The question of how long one can live with lung cancer is very difficult to answer. It should be based on the patient's physical condition and the pathological staging. However, these judgments are only based on a predictive basis and do not determine how long the patient can live. If the patient does not relapse after surgery, is sensitive to radiotherapy and chemotherapy, and shows no signs of recurrence or resistance, then their five-year survival rate is naturally higher. If the patient experiences recurrence and metastasis after surgery, then the five-year survival rate is naturally lower. Therefore, the question of how long a person can live with a malignant tumor cannot be answered generically.
