Advanced symptoms of prostate cancer brain metastasis

Brain metastasis of prostate cancer usually occurs in the late stage. At this time, chemotherapy combined with local precise radiotherapy can be used to control the progression of the disease and relieve symptoms. Generally, the recurrence rate of late-stage prostate cancer is relatively high. After treatment, regular check-ups are also required to try to prolong the patient's survival period. Symptoms may be varied, including headaches, dizziness, nausea, vomiting, and low back pain.

Symptoms of early prostate cancer are not obvious. When the prostate cancer enlarges to the point where it compresses the urethra, frequent urination, urgency, pain, increased nocturia, interrupted and slow urine flow, and thinning urine flow can occur. Middle-aged and elderly men should undergo two examinations every year, such as prostate-specific antigen and rectal examination, which can predict prostate cancer in advance. Local tumor growth will occur, resulting in compression of surrounding tissues, affecting normal urination and causing urination disorders. At the same time, it will also compress the rectum, resulting in difficulty in defecation and intestinal obstruction. In addition, it can moisten the surrounding tissues.

How long does it take for lung cancer brain metastasis to coma and death?

For non-small cell lung cancer with positive oncogenes, targeted drugs such as ernotinib and osimertinib can enter the brain, especially osimertinib, which can shrink or eliminate brain tumors, so it is also called "golden mutation". There is no definitive answer on how long a person can live after a coma occurs due to brain metastasis of cancer. It is related to the individual's constitution, the location of the tumor metastasis, and the patient's basic condition. Coma due to brain metastasis of lung cancer is one of the most serious complications of advanced lung cancer.

Will a brain tumor cause dizziness every day?

If a brain tumor causes symptoms of increased intracranial pressure, it can lead to dizziness, headache, nausea, vomiting and other symptoms. However, dizziness is common in many diseases. Ischemic-hypoxic cerebrovascular disease, intracranial infection, intracranial hemorrhage, craniocerebral injury, etc. can all cause dizziness, so they should be checked and treated in a timely manner. Dizziness manifests as intermittent or continuous bloating and pain. It is rare to experience knife-like or burning pain. Some people may also experience numbness and weakness in the limbs, speech dysfunction and other conditions. People with brain tumors may experience dizziness, but not all brain tumor patients will experience dizziness. It is only seen in brain tumors in special parts.
