What causes brain tumors?

What causes brain tumors?

Multi-factorial: There are 4 things that contribute to all tumors: 1. Genetics 2. Mutation inducing factors (examples: smoking, drinking, etc). 3. Aging 3. Unknown causes (there are definitely people without family history or obvious "bad habits" that develop brain tumors). ...Read more

Brain Tumor (Definition)

Brain cancer refers to cancer located in the brain. It can occur from a metastasis from a tumor in another part of the body or can originate in the brain. Symptoms of brain cancer include headaches, weakness, dizziness, seizures, and blurry vision. It can sometimes be asymptomatic as, for example, in patients with small cell lung cancer. It is always best to use MRI with contrast to make an evaluation, since using a CT can cause you to miss ...Read more

What causes brain tumor symptoms? Is it the swelling of the brain or the tumor itself?

What causes brain tumor symptoms? Is it the swelling of the brain or the tumor itself?

Both: Most patients with brain tumors have edema "swelling" around the tumor. Drugs, such as dexamethasone, which reduce the edema reduce the symptoms, but usually do not eliminate symptoms. This is evidence that both the tumor itself and edema contribute to the symptoms of brain tumors. ...Read more

What could cause a brain tumor?

Tumor origins: Brain tumors, like any neoplasms in the body, can be induced by an interplay of genetic and environmental factors. In other words, there are inherited predispositions in some cases.

What is the cause of brain tumor?

What is the cause of brain tumor?

Most are random: All tumors result from accumulated genetic mutations that give a growth advantage to clones of cells. Most strike at random without clear environmental risks. A few familial syndrome (turcot's, neurofibromatosis, von hippel-lindau, lifraumeni, some rarities) feature increased risk for one or more types of brain tumors. If you have a brain tumor, nothing that you did caused it. Wishing you the best. ...Read more

What is the cause of Brain tumor?

What is the cause of Brain tumor?

Dumb luck: A few genetic syndromes put people at increased risk for brain tumors. Beyond this, we almost never find a cause. Tumors result from random mutations that become propagated. No one's to blame. Scientists who build careers by demonstrating new truths have failed to identify anything credible. The cell-phones claim has no rational or empirical basis. Best wishes. ...Read more
