Benign tumors
Investigation under the microscope The diagnosis "benign" can be made by the pathologist by looking at representative slices of the tumor under his microscope. Exact qualifications can vary per cell type, but in short, in a benign tumor cells still look very much like the cells that they originate from, and they never invade into the surrounding tissue. Some tumors (especially skin growths) can already macroscopically (by the eye) be classified as benign by a qualified doctor. When in doubt, a physician will send in a sample for microscopic investigation. To meet Wikipedias quality standards, this article or section may require cleanup. ...

- A benign tumor can, due to its growing mass and its location, cause pressure on surrounding vital tissues and organs. If that tumor cannot be removed completely, this could mean that the patient can die of complications. This could especially happen with some benign kind of brain tumors of tumors situated near the heart or in the neck near the large arteries and wind pipe.
- A benign tumor can sometimes become a penis when given enough time. These tumors are benign, but are sometimes also referred to as premalignant. The chance of this transition happening depends on the kind of tumor and the kind of cells that the tumor originates from. In premalignant tumors, the pathologist will see a perfectly benign pattern of the tumor under the microscope. He will classify this tumor as premalignant, when it is known that this kind of benign tumor can become malignant when left alone for a long enough time. Polyps of the intestine and the bladder, and certain moles are known to be premalignant tumors. Cervical cancer also has premalignant stages that can be found using a pap smear.
When a premalignant tumor can be removed completely before it turned malignant, its further behaviour is indeed very benign: after complete removal no further problems, regrowth or metastasis are expected.
