Brain Cancer

We all know the function of brain. It is the main control center of our body that monitors/instructs everything thing in our body. Any disease that affects this central control system is really a big problem. And the worst thing to happen is brain cancer. Brain cancer is the development of brain tumors i.e. tumors in the brain. These could either be benign or malignant; the latter being the really harmful one.

Types of brain cancer

As most other types of cancer, brain cancer is also classified as primary brain cancer and secondary brain cancer. Primary brain cancer is the one that originates from the brain itself i.e. that originates in the brain cells. Secondary brain cancers is the one that doesn't originate from the brain cells but is instead passed on from another organ/ part of the body

Causes of brain cancer

As is the case with many other types of cancer, the causes of brain cancer is a big topic for researchers. However, certain genetic conditions and exposure of head to radiation (as received during radiotherapy as part of treatment of other conditions) are known to be causes of cancer. There are a number of other theories that keep coming up time and again, each suggesting different possible causes of brain tumor (one famous one is about mobile phones causing brain cancer). However, there really isn't a very convincing theory about what causes brain cancer.

Symptoms of brain cancer

Some very common symptoms of brain cancer are headaches and nausea; but these can really be caused by something else. So, headache and nausea shouldn't really be taken as brain cancer. Some other symptoms of brain cancer are related to incorrect working of some of the basic senses (that are mainly governed by brain) e.g. speech, vision and smell etc. Again, there is no point in getting worried all by yourself; you should, in any case, consult a qualified doctor and let them know clearly about the various symptoms that you have observed. The doctor can then diagnose whether it is brain cancer. You might be referred to a neurologist for further examination (if brain cancer is suspected).

Diagnosis and treatment of brain cancer

The diagnosis of brain cancer will include tests that are based on the working of the nervous system. So, testing of basic human senses like vision, speech, hearing, mental capability, reflexes is taken up for diagnosis of brain cancer. The treatment of brain cancer is done through surgery, radiotherapy or chemotherapy (and the combination of these).
