Understanding Skin Cancer: Prevention, Detection, and Treatment

Skin cancer is one of the most common yet preventable forms of cancer worldwide. In Australia, where sun exposure is part of daily life, the condition is especially prevalent. Thousands of Australians are diagnosed with skin cancer each year, emphasizing the importance of regular checkups, sun protection, and expert medical care. One of the leading professionals dedicated to skin health and skin cancer treatment is Dr Shaun Segal — a trusted dermatologist renowned for his commitment to patient care and evidence-based dermatology.

This blog explores everything you need to know about skin cancer — from its causes and symptoms to prevention and treatment — under the expert guidance of Dr Shaun Segal.

What Is Skin Cancer?

Skin cancer occurs when skin cells grow abnormally and uncontrollably due to damage, usually caused by ultraviolet (UV) radiation from the sun or tanning devices. The skin, being the body’s largest organ, is constantly exposed to environmental stressors, making it vulnerable to harmful UV rays.

There are three major types of skin cancer:

1. Basal Cell Carcinoma (BCC) – This is the most common form of skin cancer. It often appears as a pearly bump, red patch, or open sore that doesn’t heal. While BCC rarely spreads to other organs, it can cause local tissue damage if untreated.

2. Squamous Cell Carcinoma (SCC) – The second most common type, SCC typically looks like a scaly red patch, wart, or sore that may crust or bleed. SCC can become serious if it spreads to deeper tissues or distant body parts.

3. Melanoma – Though less common, melanoma is the most dangerous type. It can develop in existing moles or appear as a new dark spot. Melanoma spreads quickly if not detected early, making regular skin checks vital.

Dr Shaun Segal emphasizes that early detection is key — when caught in its early stages, skin cancer is highly treatable and often curable.

What Causes Skin Cancer?

While the primary cause of skin cancer is overexposure to UV radiation, other contributing factors include:

• Fair skin type – People with lighter skin tones are at higher risk due to lower levels of melanin.

• Family history – A genetic predisposition can increase your susceptibility.

• Weakened immune system – Conditions or medications that suppress immunity raise the risk.

• Age and sun exposure – Cumulative sun damage over the years leads to skin cell mutations.

• Tanning beds – Artificial UV rays from tanning devices are equally harmful as direct sunlight.

As Dr Shaun Segal explains, even short, regular sun exposure — such as driving or walking outdoors — can add up over time, making consistent skin protection essential.

Signs and Symptoms to Watch For

The first step toward protecting yourself is knowing what to look for. Skin cancer can appear in many forms, which is why Dr Shaun Segal recommends monthly self-checks and professional skin examinations.

Here’s the ABCDE rule for spotting potentially cancerous moles:

• A – Asymmetry: One half doesn’t match the other.

• B – Border: Edges are irregular, blurred, or notched.

• C – Color: Uneven shades of brown, black, or other colors.

• D – Diameter: Larger than 6mm (about the size of a pencil eraser).

• E – Evolving: Changes in size, shape, or color over time.

Other warning signs include sores that don’t heal, new growths, or lesions that itch, bleed, or crust. Dr Shaun Segal urges individuals to seek prompt medical attention if any suspicious changes occur.

Diagnosis and Skin Checks with Dr Shaun Segal

Regular skin checks are vital, especially for those living in sunny regions or with a personal or family history of skin cancer. Dr Shaun Segal offers comprehensive skin examinations using advanced diagnostic tools like dermoscopy and digital mole mapping.

• Dermoscopy allows Dr Segal to view moles and lesions in high magnification, revealing structures beneath the skin surface invisible to the naked eye.

• Mole mapping helps track changes in the skin over time, allowing for early intervention if any new or evolving lesions appear.

If a suspicious spot is found, Dr Shaun Segal may perform a biopsy — removing a small tissue sample for laboratory testing — to confirm the diagnosis and plan appropriate treatment.

Treatment Options for Skin Cancer

Depending on the type and stage of skin cancer, Dr Shaun Segal tailors treatment plans that are both effective and minimally invasive. Common treatments include:

1. Surgical Excision – The cancerous tissue is precisely removed along with a small margin of healthy skin to prevent recurrence.

2. Cryotherapy – Freezing with liquid nitrogen destroys early-stage or superficial skin cancers.

3. Topical Treatments – Special creams or gels may be prescribed for certain pre-cancerous or early cancerous conditions.

4. Photodynamic Therapy (PDT) – A light-based treatment that targets and destroys abnormal cells.

5. Advanced Surgical Techniques – For complex cases, Dr Shaun Segal ensures precise and cosmetically sensitive procedures.

Each treatment plan focuses on curing the cancer while maintaining the appearance and health of the skin.

Preventing Skin Cancer – Advice from Dr Shaun Segal

While treatment has advanced significantly, prevention remains the most powerful tool. Dr Shaun Segal advocates for daily sun protection and lifestyle changes that drastically reduce skin cancer risk.

Here are his top prevention tips:

• Apply sunscreen (SPF 30 or higher) daily, reapplying every two hours when outdoors.

• Avoid peak sun hours (10 a.m. to 4 p.m.), when UV rays are strongest.

• Wear protective clothing, hats, and UV-blocking sunglasses.

• Seek shade whenever possible.

• Avoid tanning beds — artificial UV exposure carries the same risks.

• Schedule annual skin checks with a dermatologist, even if no symptoms appear.

Dr Shaun Segal emphasizes that prevention isn’t just for adults — children and teens should also adopt healthy sun habits early, as UV damage accumulates over time.
