It develops steadily and might cause loss of function, pain, and harm to the nerves and spinal cord. The nerve sheath is a myelin layer, and they are the connective tissue that shields nerve fiber. Nerve sheath raises under the cells covering.
Fish having tumors may texture a burning sensation, weakness, pain, numbness, and a mass. Their actual reason is anonymous. It can cause by genetics or schwannomatosis. This tumor breeds within the nerve and affects them. It includes neurofibromas, schwannomas, and others.
Chromatophoromas
It is also known as pigment cell tumors are derived from chromatophores usually found in the goldfish skin or other fish species and reptiles or amphibians. There are four classifications of chromatophores, and they contain different pigment types.
The melanophores encompass brown or black color. Xanthophores comprise yellow tint, iridophores hold colorless pigments, and erythrophores encompass red pigment. All four types originate from the neural crest.
It is a very uncommon tumor that presents in fish. Most outdoor fish suffer from this cancer than pet fish. Their eyeballs get these types of tumors, but it can occur around face sides or dorsal fins. It is difficult or unable to treat. It caused eyeball removal in a severe condition.
Gonadal sarcomas

Cancer in gills

After treatment, it develops gill tissue over the affected area. This new crust creates bumps that seem like cancer. With passing time, it will enlarge or greater, with skin growing.
If the hyperplasia in serious condition, your goldfish can develop cancer. It is minor, and it is treatable and, your fish go back to their consistent situation.
Tumor located on the head
