Your skin is constantly communicating with you, and knowing how to interpret those signs—alongside routine check-ups with a dermatologist in Singapore—is one of the best ways to protect your long-term health. Although the skin is the body’s largest organ, it’s easy to overlook concerns until they become severe. In Singapore, skin cancer ranks among the most common cancers, yet early detection dramatically improves outcomes. Being familiar with early warning signals, understanding your personal risks, and practising basic preventive habits can empower you to take charge of your skin health.
This guide walks you through both common and subtle signs that deserve attention, helping you recognise when it’s time to schedule a professional evaluation.
Skin Cancer Goes Beyond Changing Moles
Many people associate skin cancer exclusively with unusual moles, but that’s only part of the picture. The two most common skin cancers—Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC)—often do not resemble moles at all. Recognising these various presentations is key to early detection.
The ABCDE Guide to Spotting Melanoma
Melanoma is the most dangerous form of skin cancer, and early identification saves lives. Use the ABCDE checklist when examining your moles, and see a dermatologist in Singapore if you notice any of the following:
- A – Asymmetry: Benign moles are usually balanced. If one half doesn’t mirror the other, take note.
- B – Border: Healthy moles have smooth, even borders. Irregular, blurred, or scalloped edges are red flags.
- C – Colour: Harmless moles tend to be one consistent shade. Multiple tones—brown, black, tan, red, blue, or white—require attention.
- D – Diameter: Melanomas often exceed 6mm, though smaller lesions can still be dangerous if they show other warning signs.
- E – Evolution: The most crucial sign. Any change in size, colour, shape, height, or symptoms (itching, bleeding, pain) should be investigated.
Another useful tool is the “Ugly Duckling” rule—if one mole looks noticeably different from the rest, it deserves closer examination.
Signs of Non-Melanoma Skin Cancers
BCC and SCC are more likely to appear on sun-exposed areas like the face, neck, and arms. They often begin as:
Basal Cell Carcinoma
- A pearly, translucent, or waxy bump
- A flat, scar-like patch with blurred edges
- A sore that heals and reopens repeatedly
Squamous Cell Carcinoma
- A firm, red bump
- A rough, scaly patch that may resemble a wart
- A rapidly growing lesion that bleeds easily
Any wound that fails to heal should be checked promptly.
Assessing Your Personal Risk Factors
Anyone can develop skin cancer, but certain conditions increase vulnerability.
UV Radiation and Sun Exposure
Ultraviolet rays—whether from the sun or tanning beds—are the leading cause of skin cancer. The damage accumulates gradually, even from daily exposure. Many people mistakenly assume tanning beds are safer; in reality, they significantly elevate melanoma risk.
Cloud coverage offers little protection, as up to 90% of UV rays still penetrate. Sunscreen is essential year-round.
Genetics, Skin Type, and Medical History
Risk increases if:
- A close relative has had melanoma
- You’ve had skin cancer before
- You experienced blistering sunburns as a child
Skin type also plays a role. Lighter skin (Fitzpatrick types I–II) burns easily and is more susceptible. However, darker skin tones are not immune. In fact, melanoma in people with darker skin often appears in less sun-exposed areas—such as palms, soles, and under nails—and is typically diagnosed later.
From Suspicion to Diagnosis: What Happens Next
If you notice:
- A new growth
- A changing or unusual mole
- A persistent sore
- A spot that seems different from others
…it’s time to book a dermatology consultation. Dermatologists in Singapore often use a dermatoscope—a tool that magnifies skin details—to evaluate lesions more accurately. If something looks concerning, a small biopsy is done to confirm the diagnosis. This quick procedure is the most reliable way to identify or rule out skin cancer.
Taking Ownership of Your Skin Health
Your skin’s condition reflects not just cosmetic concerns but important health markers. Staying alert, performing regular self-checks, and seeing a dermatologist early ensure that problems are caught while they are most treatable. With the right knowledge and habits, you can safeguard your skin and support a lifetime of healthy living.
