the uncontrolled mitosis and growth of abnormal cells.
Skin cancers, including melanoma (which is likely the "dark mass on skin" referred to in the question), are typically characterized by the uncontrolled growth and division of cells due to mutations in DNA that affect cell cycle regulation. This results in abnormal cells that divide uncontrollably, form masses, and have the potential to spread to other parts of the body (metastasize). This process is generally associated with mitotic cell division rather than meiotic division, which is involved in the production of gametes (sperm and egg cells).
