Please, C. Hardi, see a dermatologist to have this examined as soon as possible. It is impossible to tell what it is without personally examining you and looking at it with a dermatoscope, but this could be a melanoma. If it is, you will not have a problem if you have it removed when it is still in an early stage of growth.
Please let me know the outcome by updating this question.
Please see a dermatologist, surgeon or plastic surgeon as soon as you can make an appointement. Your photo looks suspicious and it is important to have it tested with a biopsy to make sure it is not a melanoma, and if it is to get proper treatement at an early stage.
