Brain malignant neoplasms, also known as brain cancer or malignant brain tumors, are a type of abnormal growth or mass of cancerous cells that originates within the brain or its surrounding structures. These tumors have the potential to invade nearby tissues and spread to other parts of the body, making them highly dangerous and life-threatening.
Brain malignant neoplasms are classified based on the type of brain cells from which they originate. The two main types are primary brain tumors, which start in the brain itself, and secondary brain tumors, which are cancer cells that have spread to the brain from another part of the body.
The causes of brain malignant neoplasms are largely unknown, although certain risk factors such as exposure to radiation, family history of brain tumors, and certain genetic conditions may increase the likelihood of developing this condition.
Common symptoms of brain malignant neoplasms include persistent headaches, seizures, changes in vision or hearing, problems with memory or concentration, and unexplained nausea or vomiting. The diagnosis of brain cancer typically involves a combination of medical history evaluation, neurological examinations, imaging tests such as MRI or CT scans, and often a biopsy to confirm the presence of malignant cells.
Treatment options for brain malignant neoplasms include surgery, radiation therapy, and chemotherapy. The specific treatment plan depends on various factors such as the type, size, and location of the tumor, as well as the overall health of the patient. The prognosis for brain cancer varies depending on the type and stage of the tumor, as well as the age and general health of the patient.
