Abstract

Cancer is the name given to a set of diseases. Cancer begins when the genetic information of a cell is destroyed, causing the cell to divide uncontrollably. The result of this abnormal division often appears as a lump or bulge, commonly known as a tumor. The tumor can be benign or malignant. The benign tumor does not multiply outside its original site and does not enter other organs, but the malignant tumor, which is made up of cancer cells, first multiplies in the same place and if treatment is not started at this stage, they can migrate to other organs, multiply and eventually become invasive cancer. The occurrence of malignancies is not a peculiarity of human tissues and is not even restricted to mammals. Possibly can affect the various animal groups. Assuming that the presence of a tumor in a tissue result of cell cycle control is lost, we can imagine that these accidents can happen in any living being that has tissue [1]. Neoplasms are common in fish and are classified similar to higher animals.
