FYI - Melanoma

Melanoma is indeed the deadliest form of skin cancer, but its prognosis significantly improves with early detection and treatment. Knowing the early signs of melanoma can help catch the disease at a treatable stage. Here's what you need to look for:

Early Signs of Melanoma

1. The ABCDE Rule

The ABCDE rule is a helpful guideline for identifying potential melanomas by examining moles and skin lesions:

• A - Asymmetry: One half of the mole or lesion does not match the other half in size, shape, or colour.
• B - Border: The edges of the mole are irregular, scalloped, or poorly defined.
• C - Colour: The colour is not uniform and may include shades of brown, black, pink, red, white, or blue.
• D - Diameter: The mole is larger than 6 millimeters (about the size of a pencil eraser), although melanomas can be smaller.
• E - Evolving: Any change in size, shape, colour, elevation, or another trait, or new symptoms such as bleeding, itching, or crusting.

2. Additional Warning Signs

• Elevated Lesions: Any new raised growth on the skin that wasn’t there before.
• Firmness: A mole or lesion that feels hard or firm to the touch.
• Growth: Any new growth on the skin, regardless of its appearance.

Types of Melanoma

1. Superficial Spreading Melanoma

• Appearance: Often flat or slightly elevated with irregular borders and varied colors.
• Common Locations: Typically found on the trunk in men and legs in women, but can occur anywhere on the body.

2. Nodular Melanoma

• Appearance: Raised, darkly pigmented bump; sometimes may not have any pigment (amelanotic).
• Growth Rate: Tends to grow more rapidly than other types.

3. Lentigo Maligna Melanoma

• Appearance: Large, flat, and tan lesions with varying shades of brown. Often appears in areas with significant sun exposure.
• Common Locations: Face, ears, arms, and upper trunk.

4. Acral Lentiginous Melanoma

• Appearance: Flat, dark lesions that may look like a bruise and are typically found on the palms, soles, or under the nails.
• Common Locations: More common in individuals with darker skin tones.

5. Amelanotic Melanoma

• Appearance: Can be pink, red, purple, or skin-coloured and lacks the dark pigment typical of most melanomas.
• Detection Difficulty: Often harder to recognize due to lack of pigmentation.

Risk Factors

Understanding the risk factors can help in being more vigilant about checking for melanoma:

• Fair Skin: People with fair skin, light hair, and light eyes are at higher risk.
• Sun Exposure: History of excessive sun exposure or sunburns, especially during childhood.
• Moles: Having many moles or atypical (dysplastic) moles.
• Family History: A family history of melanoma increases the risk.
• Personal History: Individuals who have had melanoma or other skin cancers are at higher risk.
• Weakened Immune System: Conditions or medications that suppress the immune system can increase the risk.

Self-Examination Tips

Regular self-examination is crucial for early detection. Here’s how to perform a thorough check:

1. Examine Your Entire Body: Use a full-length mirror and a handheld mirror to check your entire body, including hard-to-see areas such as the back, scalp, between the toes, and under the nails.
2. Look for New Growths: Pay attention to new moles or lesions and any changes in existing ones.
3. Check Monthly: Conduct self-examinations once a month to become familiar with your skin and notice any changes promptly.

Professional Screening

While self-examinations are important, professional screenings by a dermatologist are essential, especially for those at higher risk:

• Annual Skin Checks: Schedule an annual skin examination with a dermatologist, who can use tools like dermoscopy to examine moles more closely.
• Biopsy: If a suspicious mole or lesion is found, a dermatologist may perform a biopsy to determine if it is melanoma.

Melanoma is a serious but often treatable form of skin cancer if detected early. By knowing the early signs of melanoma, regularly performing self-examinations, and seeing a dermatologist for professional screenings, you can significantly increase the chances of early detection and successful treatment. Always protect your skin from excessive sun exposure by using sunscreen, wearing protective clothing, and avoiding tanning beds to reduce your risk of developing melanoma.
