What types of brain tumors are there, and who is likely to develop them?
Generally speaking, brain tumors can be categorized as benign (slow growing and noncancerous) and malignant (rapid growing and cancerous). Secondary tumors-those that originate in other parts of the body and then spread to the brain-are more common than primary tumors, which begin in the brain. Many types of brain tumors are named for the cells from which they grow or their location in the brain.
The question of why brain tumors develop remains unanswered. Some possibilities include environmental and occupational factors, a handful of inherited conditions, abnormal or missing genes, viruses, a defective immune system, and atypical fetal development.
Does severe headache indicate the presence of a brain tumor?
Severe headache can usually be attributed to causes other than a brain tumor. However, headache is a common symptom of brain tumors, particularly when the patient also experiences a loss of balance; nausea and vomiting that is not associated with migraine; double vision; or numbness. The constant headache that is worse in the morning than in the afternoon may also indicate the presence of a brain tumor.
What is the prognosis for people with brain tumors?
That depends on the type and grade of tumor and the patient: Children and young adults generally tend to fare better than older patients, and women better than men. While the diagnosis of a brain tumor is serious, there is hope on several fronts. Of all primary tumors-those that originate in the brain-about half are benign and can be treated successfully.
Why are some brain tumor patients treated with surgery alone, while others also undergo radiation or chemotherapy?
There is no one-size-fits-all treatment for brain tumors. It’s true that some low-grade tumors can be completely removed and cured by surgery. However, high-grade tumors (those that are the most malignant) tend to grow and spread very rapidly. Radiotherapy is used to slow the growth or reduce the size of tumors. While radiation can be delivered conventionally-that is, by using external beams aimed at the tumor-there are other techniques. Brachytherapy refers to radioactive “seeds” that are placed at the tumor site. Stereotactic radiosurgery can deliver high-dose beams to a very precise location on the tumor.
Chemotherapeutic drugs destroy cancer cells and are used to treat certain types of brain tumors. Chemotherapy often is preferred over radiation in treatment of young children with brain tumors, as radiation may have adverse effects on the developing brain.
