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 ...
Malignancy, malignant neoplasm and malignant tumor are synonymous with cancer; Malignant ascites; Malignant transformation; Non-oncologic disorders referred to as "malignant" include: Malignant hypertension; Malignant hyperthermia; Malignant otitis externa; Malignant tertian malaria (malaria caused specifically by Plasmodium falciparum)

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
While uncommon in solid tumors, chromosomal translocations are a common cause of these diseases. This commonly leads to a different approach in diagnosis and treatment of hematological malignancies. Hematological malignancies are malignant neoplasms ("cancer"), and they are generally treated by specialists in hematology and/or oncology.
Osteosarcoma is a malignant tumors which begins in the bone forming cells.It typically occurs in young patients with 75% taking place before the age of 20 as the growth centers of the bone are ...
