D33.1: Benign neoplasm: Brain, infratentorial

You have abnormal tissue in the brain. The abnormal tissue is benign.

The brain is made up of several areas. For example, the cerebrum is used to think and plan actions. In the cerebellum, movements are initialized and coordinated. The brain stem is responsible for various unconscious tasks such as breathing. The brain stem passes into the spinal cord. Your abnormal tissue is likely to have formed in the cerebellum or brain stem.

When there is abnormal growth of tissue, then this is also referred to as a tumor. The tissue in the body is made up of cells. A tumor disorder involves the cells multiplying more than normal. This results in abnormal or excess tissue forming. A tumor can be benign or malignant. The tumor you have is benign. Benign tumors do not destroy the healthy tissue and do not spread throughout the body. However, a tumor can crowd out the healthy tissue.

The symptoms with a brain tumor will depend on which side and which area of the brain is affected. A brain tumor can cause you to have a headache or seizures, for example. You may feel sick. Certain areas of the brain may also no longer work properly. You may then no longer be able to move certain muscles properly or the skin may tingle. You may also behave differently. It is also possible to have other symptoms.
