What are the symptoms of having a brain tumor?
The growth of tumors in the human brain is a particularly serious matter, constantly threatening human health. Once a tumor develops in the brain, it must be taken seriously. Generally, the mortality rate is very high when a tumor grows inside the brain. If the tumor does not compress the nerves, there are no obvious symptoms in the body. However, once the nerves are compressed, there may be obvious symptoms such as memory decline, intellectual decline, and even memory loss. Timely treatment is required to avoid threats to life.
Brain tumors are very dangerous, and patients will definitely experience some adverse symptoms. Generally speaking, if a tumor appears in a person's brain, the most typical symptom is memory decline, and the patient may also experience some other adverse symptoms.
1. Oncogenes and genetic factors have a clear familial tendency, such as neurofibromas, angioreticulomas, and retinoblastomas.
2. Physical factors: Radiation therapy can increase the incidence of tumors, especially when the radiation dose exceeds 30Gy. This can be explained by the "double hit" theory, where radiation causes the re-mutation of oncogenes within cells, leading to intercellular transformation.
3. Chemical factors: Anthracene components dominate, and methylcholanthrene is the main factor that induces gliomas. Benzene is prone to inducing pituitary tumors. Methylnitrosamines and ethylnitrosamines are strong carcinogens, especially for the central nervous system. Ethylnitrosourea is particularly prone to carcinogenesis during the perinatal period.
4. Tumor-inducing viruses: When a virus invades a cell, it is fixed within the chromosome during the S phase of DNA proliferation within the chromosome, altering genetic characteristics and leading to uncontrolled proliferation.
