What are the symptoms of bladder cancer brain metastasis?

Brain metastasis of bladder cancer is relatively common. Bladder cancer generally refers to urothelial carcinoma of the bladder. This tumor can be divided into low-grade and high-grade types. According to the biological behavior characteristics of these two pathological types of tumors, low-grade urothelial carcinoma almost never metastasizes, while high-grade urothelial carcinoma has a higher chance of metastasis. Visual impairment: Intracranial pressure can cause poor blood flow in the eye veins, causing congestion and edema, damaging visual cells in the retina of the fundus, and causing decreased vision. If bladder cancer metastasizes to the brain, it is because bladder cancer enters the skull through blood circulation.

How long does it take for brain cancer to go from early stage to late stage?

If it is found in the early stage, it should be treated early to prevent lesions. Some cancer cells grow slowly and will not show up until the end of life. Some cancer cells grow very fast and develop into cancer in a short time, such as choriocarcinoma and small cell lung cancer. If the treatment is not timely, it will grow very fast. The formation of brain tumors may be a long and complicated process. If it is found in the early stage, it should be treated early to prevent lesions. Some cancer cells grow slowly and will not show up until the end of life. Some cancer cells grow very fast and develop into cancer in a short time, such as choriocarcinoma and small cell lung cancer. If the treatment is not timely, it will grow very fast.

Can CT scan induce brain cancer?

CT is used more and more frequently as a routine examination of the brain. Many patients are worried that brain CT will cause cancer. Assuming that it takes a process for the human body to develop a tumor after being exposed to radiation, the radiation first causes the DNA of some cells to break. The damaged cells will undergo gene repair, most of which will die, and occasionally gene mutations will occur. In most cases, the mutated cells will be cleared by the immune system. Although ionizing radiation can increase the incidence of brain tumors, CT is a common examination method in clinical practice. Independent tumors, including benign tumors, malignant tumors, and metastatic tumors.
