Abstract:
The authors report three cases of malignant pheochromocytomas. Metastases occurred in the liver in two cases whereas malignancy was suspected in the third case because of recurrence and local invasion. One case was pregnant at diagnosis of pheochromocytoma. Pheochromocytoma was associated to papillary thyroïd carcinoma in another case. The treatment considered was surgery in all cases.

02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
02:18Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
