Pathology type: Brain tumor is a generic term that includes benign, low grade and malignant brain tumors. Brain cancer refers to the malignant category. When one speaks of a brain cancer, this may be a primary (originating from the brain tissue) or metastatic (originating from cancer outside of the brain). Treatment depends on the type of cancer. ...Read more

There are other types of brain tumors, such as mesotheliomas, which are not glial tumors. ...Read more
Brain Mets: (metastasis) as an entity comprise 100k per year. Lung cancer leads the league, but breast, melanoma, kidney are quite common. Prostate almost never. Only rhabdoid tumors in children commonly go to brain. This pattern stares at us, but baffles us as to why "organotropic" patterns of metastasis are so predictable. ...Read more
Both: In fact, there are tumors formed of neurons, and a significant proportion of brain tumors have cells which have both glial and neuronal characteristics. The conventional explanation for the higher frequency of glial tumors is that neurons in the brain are mostly post-mitotic, they don't divide, so they are less susceptible to dna damage causing cancer. ...Read moreSee 1 more doctor answer
Imaging & pathology: As others have noted the first step to finding a brain tumor is an imaging study such as ct or mri. The former is faster and cheaper but may miss small tumors. Once a tumor is found, a tissue diagnosis is needed, either open surgery or biopsy. This would require a neurosurgeon to tell you what is best. ...Read moreSee 2 more doctor answers

U.S. C.D.C. says...: In the last 15 years, hundreds of research studies have investigated whether health problems can be linked to cell phone use. Some of these studies have suggested the possibility that long-term, high cell phone use may be linked to certain types of brain cancer. These studies do not establish this link definitively. Scientists need to conduct more studies to learn more about this possible risk. ...Read more
Depends: Some of this depends on how large the tumor is and where it is located. Increased or severe headaches with nausea and vomiting can be a symptom, dizziness, loss of balance, visual disturbances, and even problems with hearing, blood pressure, speech, can develop. Any new, severe, or persisting neurological symptom should be neurologically evaluated. ...Read moreSee 1 more doctor answer
