However, a benign tumour is not benign in the usual sense; the name merely specifies that it is not "malignant", i.e. cancerous. While benign tumours 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 ...
Pre-cancerous, or pre-malignant tumours, are not cancerous but can develop to be so and therefore it is important for doctors to monitor these tumours closely. Several kinds of benign tumour can ...
Benign conditions that are not associated with an abnormal proliferation of tissue (such as sebaceous cysts) can also present as tumors, however, but have no malignant potential. Breast cysts (as occur commonly during pregnancy and at other times) are another example, as are other encapsulated glandular swellings (thyroid, adrenal gland, pancreas).
Amongst individuals undergoing surgical resection of a pancreatic cyst, about 23 percent were mucinous cystic neoplasms. These lesions are benign, though there is a high rate of progression to cancer. As such, surgery should be pursued when feasible. The rate of malignancy present in MCN is about 10 percent. [1]
Pathologically, precancerous tissue can range from benign neoplasias, which are tumors which don't invade neighboring normal tissues or spread to distant organs, to dysplasia, [1] a collection of highly abnormal cells which, in some cases, has an increased risk of progressing to anaplasia and invasive cancer which is life-threatening.
Rarely, these cysts may grow more extensively and form rapidly multiplying trichilemmal tumors, also called proliferating trichilemmal cysts, which are benign, but may grow aggressively at the cyst site. [4] Very rarely, trichilemmal cysts can become cancerous. [5]
There are four types of ovarian cysts — functional cysts, PCOS cysts, benign ovarian tumor and malignant ovarian tumor — that range from harmless to fatal.
They also found a seven-millimeter lesion consistent with a mucus retention cyst, which is “a benign cyst with mucus that we commonly see in the sinus regions,” she adds.
