About changes on the skin
No two people are the same. This also goes for your skin and how it evolves over time.
From the birthmarks you have since birth to moles that show up in your teenage years and early adulthood, changes on the skin are normal in the early years of a person’s life.
But if a mole suddenly starts changing in a way that fits in with the ABCD or ugly duckling criteria, or if something new on your skin seems to pop up overnight, you should get it checked.
From about the age of 25, it becomes less likely to develop new common moles. Few people develop new common moles after the age of 35. By then it is a good idea to make a habit of keeping an eye on your skin for changes.
Notice a suspicious change or something new that looks strange? Don’t be alarmed. It is probably not melanoma. There are quite a few “melanoma wannabees” out there, but to be sure get it checked.
