How do you get skin cancer?
Skin cancer develops when ultraviolet (UV) radiation from the sun or tanning beds damages the DNA inside skin cells, causing them to grow out of control and form tumours in the epidermis (the outer layer of skin).
Main Causes
· Ultraviolet (UV) Radiation: Exposure to natural sunlight or artificial sources like indoor tanning beds causes most cases of skin cancer.
· DNA Damage: UV rays mutate the instructions inside skin cells, forcing them to multiply rapidly instead of dying normally.
Key Risk Factors
· Sunburn History: Experiencing blistering sunburns—especially during childhood—greatly increases your risk. Skin Type: People with fair or pale skin, red or blond hair, blue or green eyes, or skin that burns easily are at higher risk (though anyone of any skin tone can get skin cancer).
· Moles and Freckles: Having a large number of moles, atypical moles, or lots of freckles raises the likelihood of melanoma.
· Family or Personal History: Having a blood relative with skin cancer or a personal history of the disease increases your vulnerability.
· Weakened Immune System: Conditions like HIV or taking medications after an organ transplant lower your body's defence against abnormal cell growth.
