how brain tumour occurs?

Question

i hv seen many cases of brain tumours. and i m confused and really wanna know how it occurs. as i am a biotechnology student i want to do something that will help people. so anyone who know this plz. tell

Answer 1

Brain tumors are made of cells growing and reproducing in an uncontrolled fashion.

A benign brain tumor is formed from abnormal cells that form a distinct boundary from the surrounding normal brain.

A malignant brain tumor is dangerous because it consists of cancerous cells growing into adjacent brain tissue so that it may no longer function normally. The life threatening nature of a malignant brain tumor depends on both the type of cancerous cells that comprise the tumor and the exact location of the tumor in the brain.

Tumors that arise from cells found normally in the brain are primary brain tumors while metastatic brain tumors are formed by cancer cells originating from a cancer in another part of the body such as lung or breast cancer

Answer 2

Metastatic cancers are far more common than primary tumors of the brain and spinal cord.
Aside from exposure to vinyl chloride or ionising radiation, there are no known environmental factors associated with brain tumors. Mutations and deletions of so-called tumor supressor genes are incriminated in some forms of brain tumors. Patients with various inherited diseases, such as Von Hippel-Lindau syndrome, multiple endocrine neoplasia, neurofibromatosis type 2 are at high risk of developing brain tumors.
Mobile phones (AE: cell phones) might be a cause of brain tumors, according to one report.

Answer 3

My fiance develop into clinically determined with a grade 2 glioma and develop into informed that it ought to have been there for a minimum of 15 years. i'm afraid i can't furnish any clarification extra effective than what we've been informed while he develop into clinically determined....."each so often those issues in basic terms take place ......." A tumour is in certainty a enhance and we are delivered approximately have faith that scientists don't understand each and all the bits and bobs of it. whether, each so often those issues could be genetic finding at this variety of tumour so it ought to be worth finding into.

Answer 4

I wish you or some one can solve this mastery.

At one time when I was engaged in Laser research, I was aware of the fact that lasers showed some promise.

A specific frequency of the laser may destroy the tumour but at a low levels it would be completely harmless to the other surrounding tissue.

I am retired and have loss tract of it.

Answer 5

there is no known/proven cause for the majority of brain tumors as is the case with tumors in general except for some like smoking causes lung cancer.It is hereditary in some, meaning coming from the genetic inheritance from one of the parents, in some others it is congential meaning, present since birth, in others it is primarily a cancer from elsewhere spreading by blood stream to the brain and in the vast majority the cause is unknown factors deranging the delicate genetic control which governs cell multiplications.Intrestingly since the primary brain cell unit- the neuron does not multiply in adults it is the supporting cells called glia which cause most tumors.
