Age spots, or solar lentigines, are dark, flat spots on the skin that can occur in people of all ages. But could they turn into cancer? While age spots are usually harmless, there is a risk that they could become skin cancer. Melanoma, the most serious form of skin cancer, has been linked to age spots in some cases. If an age spot changes shape, size, or color, this could be a sign that it has become cancerous. It is important to monitor age spots for any changes and to visit a doctor if any suspicious symptoms arise. Ultimately, age spots are usually harmless, but it is important to be aware of the potential risk of skin cancer.
