Learning How to Deal with Skin Cancer: Causes, Early Signs, and Prevention Tips by Dr Shaun Segal

Introduction

One such cancer is skin cancer, which is common but preventable. Each year, thousands are diagnosed, and while the numbers may seem alarming, there’s hope—most skin cancers are treatable if detected early.

Dr Shaun Segal, an expert dermatologist dedicated to skin health and cancer prevention, emphasizes that awareness is key to reducing risks and improving outcomes. In this blog, Dr Segal shares his insights on understanding skin cancer, identifying warning signs, and adopting smart habits to prevent it.

What is Skin Cancer?

Skin cancer develops when skin cells grow uncontrollably due to DNA damage, often caused by overexposure to ultraviolet (UV) rays from the sun or tanning beds. This damage leads to mutations that cause abnormal cells to multiply and form malignant tumors.

Main Types of Skin Cancer (According to Dr Shaun Segal)

Basal Cell Carcinoma (BCC)

The most common type, often appearing on sun-exposed areas like the face and neck.
BCC grows slowly and rarely spreads but should be treated early to prevent deeper tissue damage.

Squamous Cell Carcinoma (SCC)

Often appears as scaly red patches or open sores.
If untreated, SCC can spread, making early detection crucial.

Melanoma

The most dangerous form of skin cancer. It develops in melanocytes (pigment-producing cells) and spreads rapidly.
Early diagnosis greatly improves survival rates.

Causes and Risk Factors

While sun exposure is the leading cause, Dr Shaun Segal identifies several other contributing factors:

• Excessive UV exposure: Sunburns or tanning bed use can cause long-term DNA damage.
  
  
• Light skin tone: Fair skin, freckles, or light-colored eyes increase vulnerability.
  
  
• Family history: Genetic predisposition raises melanoma risk.
  
  
• Weakened immunity: Certain medications or conditions can impair the body’s defense system.
  
  
• Age: Older adults are more prone due to cumulative sun exposure.
  
  

Dr Shaun Segal emphasizes that anyone can develop skin cancer, regardless of skin tone or age—hence, regular skin checks are vital.

Early Signs to Watch For

Self-awareness is your first line of defense against skin cancer. Early diagnosis saves lives, and noticing changes in your skin can make a huge difference.

Dr Shaun Segal’s ABCDE Rule for Identifying Melanoma

• A – Asymmetry: One half of a mole doesn’t match the other.
  
  
• B – Border: Irregular, blurred, or jagged edges.
  
  
• C – Color: Multiple shades (brown, black, red, or white) in one mole.
  
  
• D – Diameter: Larger than 6mm (about the size of a pencil eraser).
  
  
• E – Evolving: Changes in size, shape, or color.
  
  

Other warning signs include non-healing sores, itchy spots, or bleeding growths.
Dr Shaun Segal advises seeing a dermatologist for any persistent skin change.

Dr Shaun Segal’s Approach to Skin Cancer Detection

Early detection and timely treatment are key. Dr Shaun Segal recommends routine dermatological checkups, especially for individuals at higher risk.

His Diagnostic Approach Includes:

• Full-body skin mapping: Comprehensive skin examination for new or changing lesions.
  
  
• Dermatoscopic examination: Magnified assessment of moles and spots.
  
  
• Biopsy (if necessary): Testing suspicious tissue for cancerous cells.
  
  

These methods ensure even minute abnormalities are caught early, preventing serious complications.

Prevention Tips from Dr Shaun Segal

Though serious, skin cancer is largely preventable through mindful daily habits.
Dr Shaun Segal recommends the following evidence-based preventive measures:

1. Use Sunscreen Daily

Apply broad-spectrum SPF 30+ even on cloudy days and reapply every two hours.

2. Avoid Peak Sun Hours

Limit exposure between 10 a.m. and 4 p.m., when UV rays are strongest.

3. Wear Protective Clothing

Opt for long sleeves, wide-brimmed hats, and UV-protective sunglasses.

4. Skip Tanning Beds

Artificial UV light is just as harmful as sunlight.

5. Schedule Regular Skin Checks

Conduct monthly self-exams and annual dermatologist visits.

Dr Shaun Segal reminds: “Skin protection isn’t seasonal — it’s a year-round commitment.”
Even indoor UV exposure (like sunlight through windows) can cause skin damage.

The Role of Diet and Lifestyle

Dr Shaun Segal highlights that a healthy lifestyle supports skin resilience.
A balanced diet rich in antioxidants, vitamins A, C, and E, and omega-3 fatty acids helps repair skin cells.

Other key tips:

• Stay hydrated.
  
  
• Avoid smoking and limit alcohol intake.
  
  
• Get enough sleep and exercise to support skin regeneration.
  
  

Common Myths and Facts About Skin Cancer

By dispelling these myths, Dr Shaun Segal reinforces that consistent protection is the true key to prevention.

When to See a Dermatologist

Dr Shaun Segal advises scheduling an appointment if you notice:

• A mole or patch that looks unusual.
  
  
• A spot that changes rapidly or causes discomfort.
  
  

Only a qualified dermatologist can differentiate between harmless growths and potential cancerous lesions.
Prompt medical attention allows for early, less invasive treatment and better outcomes.

Final Thoughts

Skin cancer awareness begins with knowledge and action.
