The brain tumours that hit our world from the air as children are a huge mystery.
In most cases, they do not have any obvious symptoms.
But there are some rare cases of them causing damage to the brain, such as a stroke.
This has prompted scientists to look into the possible causes of the brain tumor.
It is a complicated process involving different drugs, genetic analysis and a combination of tests.
Dr Michael DeBord from the University of Adelaide in Australia, said it was very difficult to know what exactly causes the brain tumor, as the tumours are not the same as those caused by cancer.
The tumour has different colours.
It also appears to have different characteristics, like different size, like on the left side of the forehead, or on the right side of your forehead, and it may be very different in size.
Dr DeBordon said it would be very hard to determine the cause of the tumour, given it was a highly rare condition.
But he said it could be due to a gene mutation, a genetic change that occurs in one part of the genome and can affect the activity of that part of that gene.
If it was genetic, then it would probably be rare, and that is why it would need a lot of testing.
Dr Jeffrey Janson from the National Institute for Health Research in the UK, said the more tests that are done, the more accurate we can get.
He said the most likely explanation was that it is an inherited mutation.
“We’re seeing these cases in the US, in Europe and elsewhere in Asia,” he said.
In the UK and the US the first confirmed case of a brain cancer was reported in 2006, with more than 700 cases in each country. “
I think it’s more likely that there are genetic differences in that region of the gene that predisposes to it.”
In the UK and the US the first confirmed case of a brain cancer was reported in 2006, with more than 700 cases in each country.
But since then, there have been a number of new cases.
The latest case was reported on Tuesday in Florida, where the National Cancer Institute said a 46-year-old woman had been diagnosed with a rare form of the cancer.
She had been on chemotherapy for the past six months.
She is currently on dialysis, and is recovering at home.
A spokeswoman for the Florida Health Department said it had been notified of the diagnosis and that the patient was being closely monitored.
The woman has been in the intensive care unit at the University Hospital of Miami, and the department was not releasing her name.
The first cases in Florida were reported in 2005.
About 300 people in the state are currently on chemotherapy, and more than 10,000 people have received radiation treatment.
The National Cancer institute said the first cases of brain cancer were reported from the UK in 2007.
It has since reported about 2,000 new cases a year.
The most common forms of brain tumouring are a diffuse glioma, a tumour in the brain and a tumours in the spinal cord, and a relatively rare type called a focal or diffuse non-small cell lung cancer.
Most people diagnosed with brain tumorous disease do not develop any symptoms, but about 15 per cent develop other forms of the disease.
The condition is more common in males than females.
Brain tumours can affect all areas of the body.
The biggest risk is for the eyes, but they can also cause headaches, weakness and even paralysis.
The brain can also affect the heart, but that is usually caused by damage to a blood vessel or other organ.
It can be treated with chemotherapy, but the brain can often be so damaged that there is no hope of recovery.
About one in five people will develop a brain injury after their tumour is removed.
A person with a brain tumor will often live for about two years.
“The most common symptom is cognitive decline, which is normally a side effect of chemotherapy,” said Dr DePauw.
“A lot of people have to stay in the hospital for six months to eight months.
Then the side effects of the chemotherapy can be severe, which can lead to dementia or other brain damage.”
Brain tumour symptoms include: difficulty speaking, thinking or seeing
