Detailed explanation-1: -Meningiomas are benign tumors that develop from the thin membranes, or meninges, that cover the brain and spinal cord. Meningiomas usually grow slowly, generally do not invade surrounding normal tissue, and rarely spread to other parts of the CNS or body.

Detailed explanation-2: -Benign tumors are those that stay in their primary location without invading other sites of the body. They do not spread to local structures or to distant parts of the body. Benign tumors tend to grow slowly and have distinct borders. Benign tumors are not usually problematic.

Detailed explanation-3: -Malignant tumours are made up of cancer cells. They: usually grow faster than benign tumours. spread into surrounding tissues and cause damage.

Detailed explanation-4: -Benign tumors tend to grow slowly and do not spread. Malignant tumors can grow rapidly, invade and destroy nearby normal tissues, and spread throughout the body.

Detailed explanation-5: -Benign tumors will grow in a contained area usually encapsulated in a fibrous connective tissue capsule. The growth rates of benign and malignant tumors also differ; benign tumors generally grow more slowly than malignant tumors.
