Brain tumors are the outgrowths of the brain that are abnormal outgrowths. Not all the brain tumors produce cancer. There are two types of tumors:

  1. Malignant tumors

These types of tumors divide repeatedly and grow in a fast manner. These tumors can spread to other body parts. Similar to other cells of body tumor cells need nutrients and blood to exist.

  1. Benign tumors

These types of tumors do not expand to other body parts.

Generally, a benign tumor is less hazardous than a malignant tumor. On the other hand, a benign tumor can cause many types of problems in our body.

Primary Brain Cancers

Our brain formed from many types of different cells. The brain cancer starts when the cells of the brain start to grow in a rapid manner and transformed into a mass of cell in an abnormal way. These abnormal cells accumulate and form a mass, which known as tumors. These tumors directly originate from the brain cells directly. Due to this reason, this type of cancer calls primary brain tumors. Primary brain tumors are pituitary adenomas, meningiomas, and primitive neuroectodermal tumors. The type of name depends upon the type of the part of the brain by which the tumor arises.

Metastatic brain cancer

The Big Diabetes Lie

This is a common type of the tumor. Metastatic tumors produce from the cancer cells of the body and spread to other parts of the body. In addition, the process by which these tumors spread is a metastasis.


There are many causes of the production of brain tumors. However, the main causes of the production of brain tumors are unknown. Nevertheless, some factors can cause brain cancer such as smoking, environmental toxins, HIV infections, radiations to the head and other genetic factors.


Some tumors show symptoms of brain cancer but some tumors cannot show the symptoms. The symptoms are different for different tumors. CT scan and MRI help to determine the presence of the cancer cells. The symptoms of primary brain cancer and metastatic brain cancer are same which have given below:

  • A headache
  • Weakness
  • Difficulty in walking
  • Clumsiness
  • Seizures
  • Altered mental status
  • Vomiting
  • Vision difficulty
  • Difficulty in speech

  • MRI
  • Biopsy

Treatment of Brain Cancer

Permanent Reversal of Type 2

The treatment of brain cancer is very difficult. There are following most common types of treatment of brain cancer:

  • Chemotherapy

Powerful drugs used in a process to kill cancer cells.

  • Surgery

Surgery is a process, which is done on many people to cure brain tumors.

  • Radiation Therapy

In this type of therapy high-energy radiation is used to kill the tumor cells. It also helps in the prevention of the growth of tumor cells.
