Are meningiomas as serious as brain cancer?

No. No. Meningiomas rarely become cancerous and tend to be found incidently at autopsy. Rarely, really big ones can cause increased intracranial pressure and have to be surgically removed. They due tend to cause seizures due to irritation on the surface of the brain.
Usually not. Meningiomas are almost always benign, which means that they rarely spread elsewhere or even grow much at all. In fact, it is commonly the case that meningiomas are found during autopsies after someone has already passed away, suggesting that these meningiomas didn't really have an effect one way or the other. Some brain cancers, on the other hand, commonly spread, which makes them more serious.
In general no. Meningiomas are usually benign brain tumors that used to be found on autopsy and now can be seen on MRI studies as incidental findings. If you are diagnosed with a meningioma on MRI the study should be repeated to be sure it is not growing. Benign meningiomas grow very slowly. It's always best to see a Neurological Surgeon so they can follow you. Good luck!

What are the symptoms of Brain cancer?

The symptoms of Brain cancer include: Headache, Nausea, Vomiting, Double vision, Hearing loss, Papilledema.

Describe the features of brain cancer.?

Like stroke but slo. Brain cancers are brain tumors in which the cells are very abnormal and grow faster and more aggressively compared to non cancer brain tumors. Exact symptoms depend of the size of tumor to where located. This ranges from stroke like symptoms to headache and confusion or seizures. Treatment include surgery, chemo and radiation therapy but prognosis overall is poor.
Variable. Any cancer in the brain could present with any number of symptoms including but not limited to headache, dizziness, vision problems, trouble concentrating, weakness, nausea/vomiting, and motor problems. Most importantly, it can also have no symptoms. The best exam to check for this is MRI with and w/o contrast.

What causes someone to develop brain cancer?

Multi-factorial. The factors help contribute to all tumor development in general 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).
Wish we knew. We know there are many factors which cause cancer. We know there are changes in genes in the dna of brain cells which can cause cancer. What we don't know is what causes that gene to change to start brain cancer. When we are able to identify the inciting event which causes a gene to change (mutate), we may be able to attack or prevent the cause instead of directing treatment at the cancer.
