While skin cancer from sun exposure is well-known, excessive sun exposure to the face and neck is a significant, often overlooked, risk factor for lip cancer, which can readily spread into the mouth. Both UVA and UVB rays inflict DNA damage. UVA penetrates deeper, suppressing immune activity and accelerating cellular aging, while UVB directly harms epidermal cell DNA. Though the body attempts repair, mistakes during this process can lead to genetic mutations. Over time, these accumulated errors in the genetic code can foster malignancy, particularly on the vulnerable lip surface, highlighting the importance of year-round sun protection, even for your mouth.
