Skin cancer — the abnormal growth of skin cells — is one of the most common yet preventable forms of cancer in the world today. With rising awareness and better diagnostic tools, early detection and prompt treatment can significantly improve outcomes for patients. In Australia, where sun exposure is high, understanding the warning signs and types of skin cancer has become a critical part of maintaining public health.
What is Skin Cancer?
Skin cancer refers to the uncontrolled and abnormal growth of skin cells, often caused by damage from ultraviolet (UV) radiation. It usually begins in the outermost layer of the skin, the epidermis, and can be triggered by prolonged exposure to sunlight or tanning beds.
The Role of UV Radiation
UV radiation damages the DNA in skin cells. Over time, this damage can build up and lead to mutations, which may result in cancerous growth. This is particularly common in countries like Australia, where outdoor lifestyles and intense sunlight contribute to increased risk.
Major Types of Skin Cancer
There are three major types of skin cancer, each with its own symptoms, severity, and treatment approach:
1. Basal Cell Carcinoma (BCC)
- Most common and least dangerous
- Appears as a pearly bump or flesh-coloured patch
- Grows slowly and rarely spreads
2. Squamous Cell Carcinoma (SCC)
- Second most common form
- Presents as a red, scaly patch or sore that doesn’t heal
- May spread if left untreated
3. Melanoma
- The most serious type
- Begins in melanocytes (pigment-producing cells)
- May appear as a new mole or change in an existing one
- Can spread rapidly and become life-threatening
Common Signs of Skin Cancer
Detecting skin cancer early increases the chances of effective treatment. Watch out for:
- Changes in size, colour, or shape of moles
- Sores that don’t heal
- Red, scaly, or crusty patches
- New growths that appear suddenly
- Bleeding or oozing from skin lesions
The ABCDE Rule for Melanoma
To spot early signs of melanoma, dermatologists recommend using the ABCDE rule:
- A – Asymmetry: One half of the mole doesn’t match the other
- B – Border: Edges are irregular, ragged or blurred
- C – Colour: Multiple colours or uneven shades
- D – Diameter: Larger than 6mm
- E – Evolving: Changing in shape, size, or colour
Risk Factors for Skin Cancer
Certain individuals may be at a higher risk due to:
- Fair skin that burns easily
- Family or personal history of skin cancer
- Excessive sun exposure or tanning bed use
- Presence of many moles or unusual moles
- Weakened immune system
Preventing Skin Cancer
While some risk factors, such as genetics, are beyond our control, others can be managed with lifestyle changes:
Sun Protection Measures:
- Wear broad-spectrum sunscreen (SPF 30+)
- Reapply sunscreen every two hours
- Wear hats, sunglasses, and long-sleeved clothing
- Seek shade during peak sunlight hours (10 am – 4 pm)
- Avoid tanning beds
Diagnosis: When to See a Doctor
If you notice any suspicious changes to your skin, it’s essential to book an appointment with a doctor. A proper skin examination or biopsy can confirm the presence of cancer and help determine the appropriate treatment.
Diagnostic Methods May Include:
- Visual examination using a dermatoscope
- Total body photography or mole mapping
- Skin biopsy for pathological testing
Treatment Options for Skin Cancer
The type and extent of treatment depend on the kind and stage of the cancer. Common treatments include:
- Surgical Excision: Removal of the cancerous lesion and surrounding tissue
- Cryotherapy: Freezing abnormal cells with liquid nitrogen
- Topical Medications: Used for superficial types
- Mohs Surgery: Precision surgery for high-risk or facial areas
- Radiation Therapy: For patients who cannot undergo surgery
- Immunotherapy: Used in advanced melanoma cases
Importance of Regular Skin Checks
Regular skin checks are crucial for early detection and prevention. It’s recommended that individuals:
- Perform monthly self-examinations
- Visit a professional for a full-body skin check annually
- Monitor any new or changing moles
At SunSkin Clinic, we provide expert skin checks, total body photography using the latest technology and surgical treatments. We encourage patients to take their skin health seriously and act promptly if they notice any changes.
Why Early Detection Saves Lives
Skin cancer — the abnormal growth of skin cells — can often be treated effectively when caught early. Survival rates for melanoma, for example, are significantly higher when diagnosed in the early stages. In fact, more than 90% of Australians survive melanoma if it is found and treated before it spreads.
Final Thoughts: Protecting Your Skin, Protecting Your Health
Australia has one of the highest rates of skin cancer in the world, making awareness and prevention all the more important. Through education, sun safety, and regular skin examinations, we can reduce the number of lives affected by this disease.
Taking the time to schedule a simple skin check could be the decision that saves your life. Skin cancer doesn’t discriminate, and prevention is always better than cure.
