Brain hemorrhage disease does not cause the occurrence of brain tumors. Brain hemorrhage can lead to neurological deficits, hemiplegia, aphasia, numbness of limbs, dizziness, choking on water or having visual field deficits. If the bleeding area in the acute stage of brain hemorrhage is large, it may also cause the risk of hydrocephalus and brain herniation, which needs to be treated actively. The cause of brain tumor is not very clear, but it mainly belongs to the tumor in the intracranial tissues, and some of them are formed by the metastasis of other body tumors to the brain. However, there are also triggering factors in life that should be avoided, such as the use of hair dye or eating pickled products in the diet, which may increase the risk of tumor, but the evidence is not sufficient in clinical practice.
