TUMOR

An abnormal mass of tissue. Tumors are a classic sign of inflammation, and can be benign or malignant. There are dozens of different types of tumors.

Their names usually reflect the kind of tissue they arise in, and may also tell you something about their shape or how they grow. For example, a medulloblastoma is a tumor that arises from embryonic cells in the inner part of the brain (the medulla). Diagnosis depends on the type and location of the tumor.

Treatment is also specific to the location and type of the tumor. Benign tumors can sometimes simply be ignored, or they may be reduced in size or removed entirely via surgery.
For cancerous tumors, options include chemotherapy, radiation, and surgery.
