7 warning signs of Skin Cancer and Why Early Detection Matters

May is Skin Cancer Awareness Month, an important reminder to check your skin and understand the signs of skin cancer. Skin cancer is the most common form of cancer in the UK, but when identified early, treatment is often highly effective.

At Glow Aesthetics by Dora, patient safety is always our top priority. We believe in careful assessment, education and timely referral to ensure every patient receives the safest and most appropriate care.

What Is Skin Cancer?

Skin cancer occurs when abnormal cells develop in the skin, usually as a result of long-term exposure to ultraviolet (UV) radiation from the sun or tanning beds. The three main types are:

• Basal Cell Carcinoma (BCC)

• Squamous Cell Carcinoma (SCC)

• Melanoma

Melanoma is the most serious form, but all skin cancers benefit from early detection and prompt treatment.

7 Warning Signs of Skin Cancer

Recognising the 7 warning signs of skin cancer can help you seek medical advice before a lesion becomes more serious.

1. A new mole or growth that appears and continues to change.

2. Changes in an existing mole, including size, shape or colour.

3. Irregular borders or asymmetrical appearance.

4. Multiple colours within one mole, such as black, brown, red or blue.

5. A sore that does not heal within a few weeks.

6. Persistent itching, tenderness or bleeding.

7. A rough, scaly or crusted patch that may be a pre cancerous skin lesion.

   
   

What Are Pre Cancerous Skin Lesions?

Pre cancerous skin lesions are abnormal areas of skin that are not cancerous yet, but have the potential to develop into skin cancer if left untreated.

The most common example is Actinic Keratosis, also known as solar keratosis. These lesions often appear as:

• Rough or sandpaper-like patches

• Red, pink or flesh-coloured areas

• Dry, scaly spots on sun-exposed skin

• Tender or itchy patches

They are commonly found on the face, scalp, ears, hands and forearms.

Why Early Detection Matters

Early detection significantly improves treatment outcomes. When skin cancer is identified in its earliest stages, treatment is usually simpler and less invasive.

Regular skin checks are particularly important if you:

• Have fair skin

• Burn easily in the sun

• Have a history of frequent sun exposure

• Use tanning beds (not recommended)

• Have many moles

• Have a personal or family history of skin cancer

  
  

The ABCDE Rule for Checking Moles

A helpful guide for spotting suspicious moles is the ABCDE rule:

• A – Asymmetry

• B – Border irregularity

• C – Colour variation

• D – Diameter greater than 6 mm

• E – Evolving or changing over time

Any mole that fits one or more of these criteria should be assessed by a healthcare professional.

Our Safety-First Approach at Glow Aesthetics by Dora

At Glow Aesthetics by Dora, every skin concern is treated with caution and care. As a clinic founded by RGN Dora Aaron, our approach is rooted in clinical knowledge, ethical practice and a commitment to patient safety.

If a lesion appears suspicious, we will not proceed with an aesthetic treatment. Instead, we advise prompt assessment by your GP or dermatologist so you can receive the appropriate medical care.

How to Protect Your Skin

Reducing UV exposure lowers your risk of skin cancer:

• Wear broad-spectrum SPF 30 or higher every day with a PA++++

• Avoid excessive sun exposure, especially between 11 am and 3 pm

• Wear hats and protective clothing

• Never use tanning beds

• Perform monthly self-checks

  
  

Book a Professional Skin Consultation

If you are concerned about a changing mole, a persistent rough patch or other pre cancerous skin lesions, professional assessment is essential.

At Glow Aesthetics by Dora, your health and safety always come first, just take a few minutes to check your skin every month. Early detection can make all the difference, your aesthetic treatment can wait until you have the all clear.
