Is it true that a severe knock on the head cause a brain tumour?

No: A blow to the head can cause a concussion and also may cause serious bleeding which needs treatment. Brain tumors are accidents of cell division and not a consequence of trauma to the brain. ...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

Frequent headaches for a 2 years and new onset eye twitching. Could it be caused by a brain tumour?

Frequent headaches for a 2 years and new onset eye twitching. Could it be caused by a brain tumour?

Unlikely: Brain tumors can and often cause headaches but 2 years is too long to blame a brain tumor for. Eye twitching has nothing to do with a brain tumor as it is normal for muscles to twitch off and on if they are tired or over worked. If you have progression of these symptoms, then you should get a medical examination done from your doctor. ...Read more

Can blow drying the hair after immediately washing it cause brain tumours?

Can blow drying the hair after immediately washing it cause brain tumours?

No: Ionizing radiation, such as experienced by patients receiving therapeutic radiation or by atomic bomb survivors, is the only established environmental cause of brain tumors. There is no data revealing that radiofrequency or electromagnetic radiation are risk factors for brain tumors. ...Read more

Docs, what's causing brain tumours in children?

Docs, what's causing brain tumours in children?

We don't know: The only known cause for brain tumors is ionizing radiation (atomic bombs, radiation treatment for cancer). A few genetic syndromes raise the risk of brain tumors (neurofibromatosis types 1 ; 2, von hippel-lindau syndrome, li-fraumeni syndrome, turcot syndrome). There's not enough data to show that radiowaves (cellphones) or electromagnetic waves (power lines) cause brain tumors in anyone. ...Read more

My father was shot in the head @ 12y. It caused him to have a brain tumour. Could the fainting and cloudiness in the head be another brain tumour?

My father was shot in the head @ 12y. It caused him to have a brain tumour. Could the fainting and cloudiness in the head be another brain tumour?

What could cause a brain tumor?

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. One environmental factors known to induce some brain tumors is radiation exposure. Unfortunately, there is much that we still do not know about how these tumors start. ...Read more

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

Neoplasms (Definition)

"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more
