Types of Brain Tumors and Sympthoms
There are many different types of brain tumors some brain tumors are non-cancerous called benign and cancerous called malignant. A brain tumor is a mass or growth of abnormal cells in the brain. Tumors may start in the brain which is primary brain tumors, or cancer may start in other parts of the body, spreading to the brain which is secondary or metastatic brain tumors.
Symptoms of Brain Tumors
Several medical tests can be used to detect or rule out a brain tumor.
- Single or multiple muscle twitches, jerks, spasms.
- Loss of consciousness and body attitude followed by twitching and relaxing muscles.
- Loss of control of body functions, such as loss of bladder control
- Change in sensation, vision, smell or hearing without losing consciousness
- Personality or memory changes
- Headaches may be a symptom of brain tumors.
- Sleeping problems
- Changes in judgment and muscle weakness or paralysis are associated with a tumor in the frontal lobe of the cerebrum.
- Difficulty on swallowing, facial weakness or double visions are symptoms of brain tumors.
Types of Brain Tumors
- Acoustic Neuroma
- Brain Metastases
- Choroid Plexus Carcinoma
- Embryonal Tumors
- Pediatric Brain Tumors
It is also known as Vestibular Schwannoma, is a non-cancerous and slow-growing tumor that develops on the vestibular nerve leading from the inner ear to the brain. Branches of this nerve directly influence the body balance and pressure from an acoustic neuroma can cause hearing loss and unsteadiness.
Astrocytoma is a kind of cancer that can form in the brain or spinal cord. These types of brain tumors begin in cells called astrocytes which support nerve cells. Astrocytoma which arises in the brain can cause seizures, headaches, and nausea. An astrocytoma can be a slow-growing tumor, or it can be destructive cancer that grows speedily.
Brain metastases occur when cancer cells spread from their original place to the brain. Any cancer can spread to the brain, but the types most likely to cause brain metastases are lung, breast, colon, kidney, and melanoma.
Choroid Plexus Carcinoma
A choroid plexus carcinoma is a malignant type of brain tumors that occurs mainly in children. It begins near the brain tissue that secretes the cerebrospinal fluid. A non-cancerous tumor of this zone is called a choroid plexus papilloma.
Craniopharyngiomas are rare benign types of brain tumor. Craniopharyngioma begins close the brain's pituitary gland, which secretes hormones. As craniopharyngioma gradually grows, it can affect the role of the pituitary gland and other near structures in the brain.
Embryonal tumors of the central nervous system are malignant tumors that start in the fetal embryonic cells in the brain. Embryonal tumors can arise at any age but mostly occur in babies and young children.
It is a type of brain tumor that can form in the brain or spinal cord. Ependymoma begins in the ependymal cells in the brain and spinal cord that line the corridors where the cerebrospinal fluid that nourishes brain flows.
Glioblastoma is a destructive type of cancer that might occur in the brain or spinal cord. It forms from astrocytes that support nerve cells. Glioblastoma might occur at any age but tends to occur often in elder adults. It can cause worsening headaches, nausea, vomiting and seizures.
Medulloblastoma is a malignant type of brain tumor that starts in the cerebellum. The cerebellum is involved in muscle coordination, balance, and movement.
Oligodendroglioma is a tumor that can occur in the brain or spinal cord. Oligodendroglioma forms from oligodendrocytes, cells in the brain and spinal cord that produce a substance that protects nerve cells.
Pediatric Brain Tumors
They are masses or growths of atypical cells that occur in a child's brain or the tissue and structures that are near it.
Pineoblastoma is a rare, destructive type of cancer that starts in the cells of the brain's pineal gland which produces melatonin that plays a role in the normal sleep-wake rotation.
