Brain is the control and coordinating center of our body and works tirelessly throughout our life. Brain has a network of nerve cells called neurons that helps in transferring and relaying of information to various body parts. Usually any extra growth inside brain is referred as brain tumor. If the tumor is malignant (has a nature to spread) the condition is called brain cancer. Your doctor needs to assess the diagnostic reports to determine the best possible treatment for you. If malignant growth is discovered then it should not be ignored as it has the potential to spread the cancerous cells to various other body parts.
