For example, a lipoma is a common benign tumor of fat cells , and a chondroma is a benign tumor of cartilage-forming cells (chondrocytes). Adenomas are benign tumors of gland-forming cells, and are usually specified further by their cell or organ of origin, as in hepatic adenoma (a benign tumor of hepatocytes , or liver cells).
In the case of an existing tumour, a biopsy would then be required to make a diagnosis and distinguish whether the tumour is malignant or benign. [8] This involves examination of a small sample of the tissue in a laboratory. [8] If detected as a malignant tumour, treatment is necessary; treatment during early stages is most effective. [8]
A neoplasm can be benign, potentially malignant, or malignant . [9] Benign tumors include uterine fibroids, osteophytes, and melanocytic nevi (skin moles). They are circumscribed and localized and do not transform into cancer. [8] Potentially-malignant neoplasms include carcinoma in situ. They are localised, and do not invade and destroy but in ...
Similarly, a cancer arising from malignant fat cells would be termed a liposarcoma. For some common cancers, the English organ name is used. For example, the most common type of breast cancer is called ductal carcinoma of the breast. Benign tumors (which are not cancers) are usually named using -oma as a suffix
For example, a benign tumor of smooth muscle cells is called a leiomyoma (the common name of this frequently occurring benign tumor in the uterus is fibroid). Confusingly, some types of cancer use the -noma suffix, examples including melanoma and seminoma .
This results in uncontrolled cell division in the body. The uncontrolled and often rapid proliferation of cells can lead to benign or malignant tumours (cancer). Benign tumors do not spread to other parts of the body or invade other tissues. Malignant tumors can invade other organs, spread to distant locations and become life-threatening.
They can be benign or malignant. [1] [a] A neoplasm is an abnormal growth of tissue that usually forms a tissue mass. [2] [3] [4] Vaginal neoplasms may be solid, cystic or of mixed type. [5] Vaginal cancers arise from vaginal tissue, with vaginal sarcomas develop from bone, cartilage, fat, muscle, blood vessels or other connective or supportive ...
Although often described as benign, a teratoma does have malignant potential. A UK study of 351 infants and children diagnosed with "benign" teratoma reported 227 with MT, 124 with IT. Five years after surgery, event-free survival was 92.2% and 85.9%, respectively, and overall survival was 99% and 95.1%. [51]
