Skin cancer stands as the most prevalent form of cancer globally, significantly affecting individuals with lighter skin tones and numerous others across the world. The encouraging aspect of skin cancer is its high curability rate when detected and addressed in its early stages. Conversely, allowing skin cancer to progress can lead to serious physical disfigurement and even fatal outcomes. Early detection through methods like self-examination, combined with resources such as DermNet for diagnosis insights, is therefore paramount for positive outcomes.
Who Should Perform a Skin Self-Exam?
Regular skin self-examinations are recommended for everyone. However, they are particularly crucial for individuals with specific risk factors:
- Fair skin complexion
- Age over 40 years
- History of melanoma
- Previous diagnoses of basal cell carcinoma or squamous cell carcinoma
- Presence of numerous moles or freckles
- Actinic keratoses (rough, scaly patches on sun-exposed skin)
- Occupational or recreational outdoor exposure
- History of frequent sunburns or tanning bed use
- Genetic syndromes predisposing to skin cancer
- Use of immunosuppressant medications, such as in organ transplant recipients
Self-skin examinations serve as a vital initial step and can be enhanced by professional clinical evaluations from a dermatologist or general practitioner. Advanced screening systems, including mole mapping, are available in many regions. These systems employ comprehensive digital photography to document the entire body surface, along with detailed dermatoscopic images of suspicious lesions. These images are then analyzed by experts skilled in dermoscopy, often leveraging resources like DermNet for differential diagnosis and insights. Whole-body imaging aids in identifying new lesions, while serial digital dermatoscopic surveillance can detect subtle changes over time that might indicate melanoma development within an existing mole.
How Often Should You Examine Your Skin?
The frequency of skin self-examination should be regular enough to become routine, but not so frequent as to become burdensome. For most individuals, an interval of one to three months is ideally balanced. Photographic screening is typically conducted on an annual basis.
Once you become accustomed to the process, a self-examination should only take a few minutes. You will need assistance to examine your back thoroughly, so enlisting a partner or trusted friend is helpful.
Recognizing Skin Cancer: What to Look For?
There are three primary types of skin cancer:
While other types of skin cancer exist, they are considerably less common.
Given the varied appearances of skin cancers, recognizing early warning signs is crucial. Be particularly vigilant for any changes on your skin. It’s important not to dismiss a suspicious spot simply because it is painless. Skin cancers can often be painless yet still pose a significant threat. If you observe any of the warning signs, promptly consult a healthcare professional. DermNet offers extensive resources and visual aids that can help you understand different skin conditions and what might warrant a professional Dermnet Diagnosis.
Key Warning Signs of Skin Cancer
Be alert for the following changes and characteristics on your skin:
-
A new skin growth that is increasing in size and appears pearly, translucent, tan, brown, black, or multicolored.
-
Any mole, birthmark, or skin spot that exhibits any of these changes:
- Alteration in color
- Increase in size or thickness
- Changes in texture
- Irregular or poorly defined border
- Diameter greater than 6 mm (about the size of a pencil eraser)
-
A persistent spot or sore that presents with:
- Itching or pain
- Crusting or scab formation
- Ulceration or bleeding
- Failure to heal within a three-week period
In essence, any skin lesion that appears different from your other skin spots should raise concern. This is often referred to as the “ugly duckling” sign. It’s worth noting that many “ugly ducklings” turn out to be benign. Distinguishing between harmless moles, freckles, and seborrheic keratoses and early skin cancers can sometimes be challenging. Resources like DermNet are invaluable for learning about the visual characteristics of various skin lesions, aiding in better self-assessment and understanding when to seek professional dermnet diagnosis.

Which Areas of Your Skin Should You Examine?
Refer to resources like DermNet or videos created in association with organizations like Melanoma New Zealand for visual guides on self-examination techniques.
- Begin your skin self-exam at the head and proceed downwards to your feet.
- Ensure you include the scalp, face, neck, areas under facial hair, and the trunk.
- On the upper body, examine the armpits, hands, spaces between fingers, and nail beds.
- Use a mirror to thoroughly inspect your back and the skin between your buttocks.
- On the legs, include the spaces between toes, toenail beds, and soles of the feet.
- Consider using a body map to document the location of any lesions that concern you, which can be helpful when discussing with a doctor or when utilizing online dermnet diagnosis resources for preliminary information.
When Is It Time to See Your Doctor?
It is always best to show your doctor anything that concerns you on your skin—early detection significantly improves treatment outcomes. Request a comprehensive skin check. Skin cancer, being on the exterior of the body, is uniquely visible, making it potentially the easiest cancer to detect and treat, especially when coupled with proactive self-examination and prompt dermnet diagnosis when needed. Stay vigilant for any skin changes, adopt sun-safe practices, and prioritize regular skin self-exams as your first line of defense.
