Skin cancer happens when the cells in your skin start to grow abnormally. This can be triggered by damage to the DNA in skin cells. The main causes include:

• Ultraviolet (UV) radiation from the sun: The biggest risk factor. Long-term sun exposure or repeated sunburns can damage skin cells.
• Tanning beds: Artificial UV light can also harm the skin and increase cancer risk.
• Genetics: A family history of skin cancer can make you more likely to develop it.
• Fair skin or light eyes: People with less melanin in their skin are more prone to damage from UV rays.
• Weakened immune system: Certain medications or health conditions that affect immunity can raise the risk.
• Exposure to harmful chemicals: Some chemicals or radiation can increase skin cancer chances.
  

Early detection is key. Regular skin checks and protecting your skin from the sun can help prevent serious problems.
