Squamous Cell Carcinoma
Warning Signs

Early Detection Best Practices

When caught promptly, almost all squamous cell carcinomas (SCCs) of the skin can be successfully treated. But when they become more advanced, these skin cancers can become dangerous.

That’s why it’s important to be on the lookout for any SCC warning signs, including new, changing or unusual skin growths.

How to spot an SCC

SCC of the skin can develop anywhere on the body but is most often found on exposed areas exposed to ultraviolet (UV) radiation like the face, lips, ears, scalp, shoulders, neck, back of the hands and forearms. SCCs can develop in scars, skin sores and other areas of skin injury. The skin around them typically shows signs of sun damage such as wrinkling, pigment changes and loss of elasticity.

SCCs can appear as thick, rough, scaly patches that may crust or bleed. They can also resemble warts, or open sores that don’t completely heal. Sometimes SCCs show up as growths that are raised at the edges with a lower area in the center that may bleed or itch.

SCCs can also look different from the descriptions above. If you notice anything unusual, such as a sore that fails to heal, or a new spot, make an appointment with your dermatologist.

Please note: Since not all SCCs have the same appearance, these photos serve as a general reference for what they can look like.

What you can do

Examine yourself head to toe once a month: Keep an eye out for new or changing lesions that grow, bleed, or do not heal. Learn how to check your skin here.

When in doubt, check it out. Follow your instincts and visit your doctor if you see a spot that just doesn’t seem right.

See your dermatologist for a professional skin exam every year even if you don’t see anything suspicious. These specialists are skilled at identifying and treating abnormal skin growths that may be undetectable to the untrained eye and can check areas of your body that are difficult for you to see yourself.

Follow up regularly: Especially if you’ve already had either SCC or basal cell carcinoma (BCC), melanoma or precancers like actinic keratosis, be sure to see your dermatologist for a skin exam at recommended intervals.

Practice sun safety: Making daily sun protection a part of your lifestyle is the single most effective way to reduce your risk of developing skin cancer.
