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]
The word benign means ' favourable, kind, fortunate, salutary, propitious '. [1] 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]
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 ...
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 .

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 ...
A precancerous condition is a condition, tumor or lesion involving abnormal cells which are associated with an increased risk of developing into cancer. [1] [2] [3] Clinically, precancerous conditions encompass a variety of abnormal tissues with an increased risk of developing into cancer.
Liver tumors can be classified as benign (non-cancerous) or malignant (cancerous) growths. They may be discovered on medical imaging (even for a different reason than the cancer itself), and the diagnosis is often confirmed with liver biopsy. [2]
