When to Seek Medical Advice for Melanoma Skin Changes

Author : Canberra Skin Cancer Clinic | Published On : 12 Nov 2026

Melanoma cancer treatment is an important topic for anyone concerned about unusual skin changes, new moles or suspicious spots. Melanoma is a type of skin cancer that develops in melanocytes, the cells responsible for producing skin pigment. Early detection plays an important role in identifying melanoma and understanding suitable treatment options.

Many skin changes are harmless, but some may require medical attention. Knowing what to look for and when to arrange a professional skin examination can help you take better care of your skin health. If you notice a changing mole, unusual spot or new skin growth, do not ignore it.

Understanding Melanoma and Its Early Signs

Melanoma develops when pigment-producing skin cells grow abnormally. It can appear on different parts of the body, including areas that receive regular sunlight and areas that are not commonly exposed to the sun.

Unlike some other skin cancers, melanoma can spread to other parts of the body if it is not detected and treated early. This makes awareness and regular skin checks particularly important.

Some common warning signs include:

  • A new mole or unusual spot on the skin.

  • Changes in the size, shape or colour of an existing mole.

  • A mole with uneven or irregular borders.

  • A spot with multiple colours or different shades.

  • Itching, tenderness or bleeding around a mole.

  • A skin lesion that continues to change over time.

Not every unusual spot indicates melanoma. However, it is important to seek medical advice if you notice something different or concerning.

1. Follow the ABCDE Rule to Identify Warning Signs

The ABCDE rule is a useful method for recognising possible melanoma warning signs. It helps people understand which changes in a mole may require professional assessment.

A: Asymmetry

One half of the mole looks different from the other half. The shape may appear uneven.

B: Border

The edges may look irregular, blurred, uneven or poorly defined.

C: Colour

The mole may contain different colours, such as brown, black, red, white or blue.

D: Diameter

Melanomas are often larger than 6 mm when diagnosed, although they can also be smaller.

E: Evolving

The mole changes in size, shape, colour or appearance over time. It may also develop itching or bleeding.

If you notice any of these changes, arrange a medical assessment rather than trying to diagnose the spot yourself.

2. When Should You Seek Medical Advice?

You should consider booking a medical appointment whenever you notice a new or changing skin spot that concerns you.

Some people delay skin examinations because they do not experience pain or discomfort. However, melanoma does not always cause noticeable symptoms during its early stages.

Seek medical advice if:

  • A mole suddenly changes in appearance.

  • A new spot looks different from your other moles.

  • An existing mole becomes darker or develops uneven edges.

  • A skin lesion starts bleeding without an obvious injury.

  • A spot develops persistent itching or tenderness.

  • A wound or skin lesion does not heal as expected.

You do not need to wait until a spot becomes painful before seeking professional advice. Early assessment can help identify concerns and determine whether further investigation is necessary.

3. Why Regular Melanoma Checks Are Important

A regular melanoma check helps identify suspicious skin changes that may not be easy to notice during everyday activities. Checking your skin regularly allows you to become familiar with your moles, spots and normal skin appearance.

During a professional skin examination, a medical practitioner may:

  • Examine your skin for unusual moles and lesions.

  • Check spots that have changed in appearance.

  • Use a dermatoscope to examine suspicious areas more closely, when appropriate.

  • Recommend further assessment or a biopsy if required.

  • Explain the next steps based on the examination findings.

People with a history of skin cancer, many moles, a family history of melanoma or significant sun exposure may need more frequent skin checks. Your doctor can recommend an appropriate examination schedule based on your individual risk factors.

4. Understanding Melanoma Diagnosis

If a doctor identifies a suspicious skin lesion, they may recommend further tests to understand its nature.

The diagnostic process may include:

Clinical skin examination: The doctor examines the suspicious area and reviews its appearance, size, colour and changes over time.

Dermatoscopy: A special magnifying device helps the doctor examine structures beneath the skin's surface.

Skin biopsy: If melanoma is suspected, the doctor may remove all or part of the lesion for laboratory examination. A biopsy helps confirm whether cancer cells are present.

Further investigations: If melanoma is confirmed, additional tests may help determine whether it has spread to other parts of the body.

An accurate diagnosis helps doctors understand the condition and recommend suitable care.

5. What Are the Available Melanoma Cancer Treatment Options?

The right approach to melanoma cancer treatment depends on several factors, including the stage of melanoma, its thickness, location and whether it has spread.

Common treatment options include:

Surgical Removal

Surgery is commonly used to remove melanoma, particularly when doctors detect it at an early stage. The surgeon removes the affected skin along with a margin of surrounding healthy tissue.

Sentinel Lymph Node Biopsy

For certain melanomas, doctors may recommend checking nearby lymph nodes to understand whether cancer cells have spread.

Immunotherapy

Immunotherapy uses medicines that help the body's immune system recognise and attack cancer cells. Doctors may recommend it for certain higher-risk or advanced melanomas.

Targeted Therapy

Some melanomas contain specific genetic changes, such as BRAF mutations. Targeted medicines may help block signals that allow these cancer cells to grow.

Radiation Therapy

Radiation therapy uses high-energy radiation to destroy cancer cells. Doctors may recommend it in selected situations, depending on the patient's condition.

Not every patient needs all these treatments. A qualified specialist will explain the suitable options after reviewing the diagnosis and individual circumstances.

6. Protect Your Skin and Reduce Risk

Although you cannot prevent every case of melanoma, protecting your skin from excessive ultraviolet (UV) exposure can help reduce your risk.

Follow these simple sun protection habits:

  • Apply broad-spectrum SPF 50 or SPF 50+ sunscreen.

  • Reapply sunscreen as directed, particularly after swimming or sweating.

  • Wear protective clothing, sunglasses and a wide-brimmed hat.

  • Seek shade when UV levels are high.

  • Avoid using tanning beds and sunlamps.

  • Check your skin regularly for unusual changes.

In Australia, sun protection is especially important because UV radiation can reach harmful levels throughout the year.

7. Choosing the Right Skin Cancer Clinic in Canberra

When you notice a suspicious mole or unusual skin change, choosing an appropriate clinic for assessment is an important step. Look for a medical team that offers professional skin examinations, clear explanations and guidance about further investigations when needed.

Before booking an appointment, consider asking about the clinic's skin check services, assessment process and available treatment options.

You can also review a medical practitioner's qualifications and experience before making an appointment. For reference, you can view Dr Senthil Kumaar's HotDoc profile.
