Anyone who has had one squamous cell tumor has an increased chance of developing another, especially in the same skin area or nearby. That is usually because the skin has already suffered irreversible sun damage. Such recurrences typically occur within the first two years after surgery. An squamous cell carcinoma can recur even when it has been carefully removed the first time.

Thus, it is crucial to pay particular attention to any previously treated site, and any changes noted should be shown immediately to a physician. squamous cell carcinomas on the nose, ears, and lips are especially prone to recurrence. Even if no suspicious signs are noticed, regularly scheduled follow-up visits including total-body skin exams are an essential part of post-treatment care. Should the cancer return, the physician may recommend a different type of treatment the next time; certain methods, such as Mohs micrographic surgery, can be highly effective for recurrences.

PREVENTING SKIN CANCER

While squamous cell carcinomas and other skin cancers are almost always curable when detected and treated early, it is best to prevent them in the first place. Make these sun safety habits part of your daily health care routine:

• Seek the shade, especially between 10 AM and 4 PM.
• Do not burn.
• Avoid tanning and UV tanning booths.
• Cover up with clothing, including a broad-brimmed hat and UV-blocking sunglasses.
• Use a sunscreen with an SPF of 15 or higher every day.
• Apply 1 ounce (2 tablespoons) of sunscreen to your entire body 30 minutes before going outside. Reapply every two hours or after swimming or excessive sweating.
• Keep newborns out of the sun. Sunscreens should be used on babies over the age of six months.
• Examine your skin head-to-toe every month.
• See your doctor every year for a professional skin exam.
