Is brain tumor rare in India?

Unlike popular belief that brain cancers are a common occurrence in India, the incidence of brain cancers is found to be extremely rare in India. Only two or three out of 1,00,000 people are affected accounting for less than 2% of the total number of malignancies diagnosed.

Are benign brain tumors rare?

Why do brain tumors come?

Doctors are not sure what causes most brain tumors. Mutations (changes) or defects in genes may cause cells in the brain to grow uncontrollably, causing a tumor. The only known environmental cause of brain tumors is having exposure to large amounts of radiation from X-rays or previous cancer treatment.

Is brain tumor fully curable?

The outlook for a malignant brain tumour depends on things like where it is in the brain, its size, and what grade it is. It can sometimes be cured if caught early on, but a brain tumour often comes back and sometimes it isn’t possible to remove it.

Types of Benign Brain Tumors Chordomas are benign, slow-growing tumors that are most prevalent in people ages 50 to 60. Craniopharyngiomas typically are benign, but are difficult tumors to remove because of their location near critical structures deep in the brain.

Why are brain tumors so deadly?

This higher level of mortality can possibly be linked to the fact that the brain is the most delicate organ in the human body and contains the very core of many of our functions and human characteristics. Brain tumors can interrupt critical brain functions but so can removal of those tumors. 1
