A melanoma is a type of skin cancer which usually begins in melano cysts. It generally conquers nearby tissues and spreads to various parts of body. It is potentially dangerous and spreads to lungs, bones or brains. These can occur on any skin surface because most melanocytes are generally found in skin. They generally grow from nevus or dysplastic moles. In men, melanoma is generally found in upper body parts whereas women generally have melanoma in lower parts of their body.
Melanoma, unlike common moles and dysplastic moles is cancerous and highly dangerous. They are asymmetrical and usually increase in size with time. They are generally larger than 6 millimeters in size. They can only be diagnosed by removing the tissue and looking for cancer cells. All part is removed which looks abnormal. This sample collection can be done instantly after which it is send to labs for further checkups.
There are several risks which can help in growing a melanoma. Having more than 50-60 common moles or having dysplastic mole have a greater risk. The sun light consists of UV radiations which help in damaging the skin and other skin diseases. Severe sunburns also have a greater risk of growing a melanoma.
