Definition


A tumor is a generic term defining a newly developed tissue within normal tissue. Tumors are caused by dysfunctional cellular development. As opposed to commonly-held theory, the term "tumor" is used not only for cancerous diseases, but also for other tissue growths that are benign. Qualifying a tumor as benign (non cancerous) or malignant (cancerous) can be possible on studying the tumor's aspect by means of medical imaging, but is often confirmed by biopsy, where a sample is taken for analysis. In some cases, surgical ablation can be required. In others, all that is needed is to monitor its progression by follow-up and medical imaging procedures.
