However, a benign tumor is not benign in the usual sense; the name merely specifies that it is not "malignant", i.e. cancerous. While benign tumors usually do not pose a serious health risk, they can be harmful or fatal. [2] Many types of benign tumors have the potential to become cancerous through a process known as tumor progression. For this ...
Cutaneous lipomas are rare in children, but these tumors can occur as part of the inherited disease Bannayan-Zonana syndrome. [40] [41] Lipomas are usually relatively small with diameters of about 1–3 cm, [42] but in rare cases they can grow over several years into "giant lipomas" that are 10–20 cm across and weigh up to 4–5 kg.

Eighty percent of African American women will develop benign uterine fibroid tumors by their late 40s, according to the National Institute of Environmental Health Sciences. [74] African American women are two to three times more likely to get fibroids than Caucasian women.

[8] [7] Cancer that has spread from the colon, bladder, and stomach is far more common than cancer that originates in the vagina itself. [9] Some benign tumors may later progress to become malignant tumors, such as vaginal cancers. [10] [11] Some neoplastic growths of the vagina are sufficiently rare as to be only described in case studies. [3]
Fibroadenoma of the breast is a benign tumor composed of a biplastic proliferation of both stromal and epithelial components. [ 12 ] [ 13 ] This biplasia can be arranged in two growth patterns: pericanalicular (stromal proliferation around epithelial structures) and intracanalicular (stromal proliferation compressing the epithelial structures ...
Multiple endocrine neoplasia (abbreviated MEN) is a condition which encompasses several distinct syndromes featuring tumors of endocrine glands, each with its own characteristic pattern. In some cases, the tumors are malignant, in others, benign. Benign or malignant tumors of nonendocrine tissues occur as components of some of these tumor ...
Hepatocellular adenoma (also known as hepatic adenoma or hepadenoma) is a rare, benign liver tumor. It most commonly occurs in people with elevated systemic levels of estrogen , classically in women taking estrogen-containing oral contraceptive medication.
