What is Skin Cancer
Skin cancer is defined as the abnormal, uncontrolled growth of skin cells, most often triggered by ultraviolet (UV) radiation from the sun or tanning beds — a particular risk given the intense sun exposure in Singapore. This UV damage mutates the skin cell DNA, leading to unregulated multiplication and the formation of malignant tumors. These typically manifest as new growths, changing moles, or non-healing sores, usually appearing on sun-exposed areas.
Understanding your risk factors — such as family history, prolonged sun exposure, or weakened immunity — is vital, as early detection is key to effective treatment. When diagnosed promptly, skin cancer, including aggressive forms like melanoma, can be treated.
Types of Skin Cancer
There are several types of skin cancer, each with its own distinct characteristics and requiring specific treatment approaches.
Signs and Symptoms of Skin Cancer
Recognising the early warning signs of skin cancer is critical for prompt diagnosis and effective treatment. If you notice any of the following symptoms, especially on sun-exposed areas, seek professional advice:
- New or Unusual Growths: The appearance of a new spot, lump, or discoloured patch on your skin.
- Changing Moles or Spots: Moles or spots that change in size, shape, or colour. For guidance on monitoring changes, you can schedule a professional mole check in Singapore with Dr Ee.
- Irregular Features: Moles with raised or irregular borders, uneven colour, or asymmetry (where one half doesn’t match the other).
- Non-Healing Lesions: Sores or lesions that bleed, itch, or do not heal within several weeks.
- Persistent Patches: Scaly or red patches that persist, enlarge over time, or become itchy or tender.
When to See a Skin Cancer Specialist
Early intervention significantly improves outcomes. It is important to book an evaluation with a skin cancer specialist in Singapore, like Dr Ee, if you identify any high-risk factors or suspicious symptoms:
- Suspicious Changes: Any changes in the size, shape, colour, or texture of existing moles or skin lesions.
- Persistent Symptoms: Sores, scaly patches, or growths that do not heal or persist for more than four weeks.
- High-Risk History: A significant family history of skin cancer (especially melanoma) or a personal history of excessive or prolonged sun exposure.
- Previous Diagnosis: If you have previously been diagnosed with any type of skin cancer.
What are the Stages of Skin Cancer?
Skin cancer is classified into stages based on the size of the tumour, its depth of invasion, and whether it has spread to other parts of the body. Staging helps guide the appropriate approach to skin cancer treatment in Singapore.
Stage 0 (Carcinoma in situ)
Cancer cells are confined entirely to the top layer of the skin (epidermis). This stage is usually highly treatable with early intervention.
Stage I
The tumour is small and localised, with minimal invasion into the deeper skin layers (dermis). The risk of spread is low.
Stage II
The tumour is larger or has invaded deeper into the skin layers. This stage indicates a slightly higher risk of spreading locally.
Stage III
The cancer has spread beyond the primary site to nearby tissues, such as lymph nodes. This stage typically requires more intensive, comprehensive treatment.
Stage IV
The cancer is advanced and has metastasised (spread) to distant organs (e.g., lungs, brain). Treatment at this stage may require systemic therapy, such as chemotherapy, immunotherapy, or targeted therapy.
