Moles can be dangerous because they have a high risk of being cancerous. Melanoma is when pigment producing cells that give color to the skin become cancerous. That is why cancerous moles are usually changing in color and have irregular edges, rather than simply round, brown or black. Melanoma spreads quickly and starts affecting other parts of the body. If you have a mole you might think is cancerous, get it examined by a healthcare professional immediately. Early deduction for moles makes a huge difference. In many recent students it is shown that there is a 99% 5 year survival rate for patients whose melanoma cancer is detected early. These rates tend to drop if the cancer has spread and reached lymph nodes or other distant organs. Always check the ABCDES of melanoma. Another strategy is to look for the ugly duck, a medical warning sign where one mole stands out from the others as abnormal.
