Fish Are Not Immune To Cancerous Tumors

Fish are not immune to cancerous tumors. It is critical that all growths or tumors seen on your fish are diagnosed by a qualified veterinary doctor. Waiting on treatment can seriously impact the prognosis of your pet fish. Neurofibromas are benign tumors. They do not cause the fish any distress other than temporary hydrodynamic resistance. These pigment cell tumors are seen in koi, butterfly fish, and Corydoras catfish species. Surgical removal under anesthesia is often curative. Gonadal sarcoma is a common type of reproductive tumor. It occurs more often in older female koi.

If caught early enough, a fish can be removed from the tumor.

If not, the tumor will continue to grow and interfere with normal organ functions. Tumors can be diagnosed using many diagnostic techniques. Depending on the location of the tumor, your veterinary doctor can use multiple diagnostic methods to determine its source and best treatment. For external tumors, a simple biopsy or cytological sample is used.

It collects a few cells of the brain. Sometimes, surgical excision is used to remove a tumor. Internal tumors will require surgery. Traditional cancer therapies, such as chemotherapy and radiation therapy, have not been utilized much. Many fish have undergone successful surgical treatment for various types of internal tumors. The fish is anesthetized and removed from water. This keeps it wet. Fish bred for external appearances may be selecting for potential tumors. Good water quality and good nutrition can go a long way in preventing diseases in fish. If one starts to look odd, contact your aquatic veterinary doctor as soon as possible to ensure that your fish have a long life. . . .
