Tumors are of two types, benign or malignant. A benign tumor is not considered cancer. It is slow growing, does not spread or invade surrounding tissue, and once it is removed, doesn't usually recur. A malignant tumor, on the other hand.
No, not all types create tumors.
Malignant tumors
Benign tumors (non-cancerous) such as brain tumors.
Pituitary adenomas (adenomas are tumors that grow from gland tissues) and pituitary tumors in children and adolescencents (craniopharyngiomas) are the most common types of pituitary tumors.
Two types of tumors are benign and malignant tumors. Benign tumors are usually harmless and grow at a slow rate. However, they can grow larger and become problematic. Malignant tumors are the opposite, growing at a fast rate and causing serious health problems.
Rhabdomyosarcomas are rare types of muscle tumors. They typically grow on the tissue of striated muscle. These tumors are usually malignant.
Pleural tumors are divided into two classifications: primary (mesothelioma), or metastatic (arising from cancer sites elsewhere in the body).

Malignant tumors. Malignant tumors have the ability to invade the surrounding tissue. Often malignant cells enter the bloodstream vessels and lead to tumor growth in other areas of the body.
