Brain Cancer

 

 

 

 

 

Brain cancer begins with abnormal and uncontrolled growth cells in the brain resulting in the formation of primary brain Tumors. There are two types of Tumors which can be formed:

Malignant Tumors – arise from cancerous cells. These Tumors grow rapidly, has distinct boundaries and can spread to surrounding brain tissues.

Benign Tumors which arise from non-cancerous cells. These Tumors grow slowly, has irregular boundaries and do not spread to other tissues.

Cancer cells from other parts of the body can spread to the brain, causing the formation of tumors in the brain known as metastatic brain tumors.

 

 

 

 

 

 

All these tumors in the brain are dangerous because they cause damage to healthy brain cells and disrupt with normal brain function. Brain tumors are further classified by where they are located in the brain, how fast the tumors grow and the type of cell which the tumor grows from.

SYMPTOMS

These are general symptoms which experienced by patients with brain cancer however it varies from patient to patient depending on the size, type and location of the tumor

  1. Headaches

  11. Memory problems

In some cases, there may be no symptom.

CAUSES

RISK FACTORS

  7. PET scan
