How to Identify Suspicious Moles: Signs of Skin Cancer

Skin cancer is one of the most common types of cancer, and early detection plays an important role in successful treatment. Recognising the early signs of skin cancer by examining moles and other skin changes is key to catching the disease in its early stages. At iQonic, we believe in empowering our patients with the knowledge needed to identify suspicious moles and take the necessary steps to protect their skin health. In this blog, we will guide you through the signs of suspicious moles and skin changes that could indicate the presence of skin cancer.

The Importance of Regular Skin Checks

Regular skin checks allow you to monitor your moles and skin changes over time, helping you spot anything unusual early on. While most moles are harmless, some may develop into melanoma or other forms of skin cancer, making it important to stay vigilant. A self-examination once a month can help you detect potential issues early, and if you notice any changes or new growths, it’s crucial to consult a dermatologist for further assessment.

The ABCDE Rule for Spotting Suspicious Moles

The ABCDE rule is a widely used guideline for identifying the early warning signs of melanoma, the most serious form of skin cancer. It helps you evaluate the appearance of moles and determine whether they may require further investigation.

A: Asymmetry

• A healthy mole is usually symmetrical, meaning that if you draw an imaginary line through the middle, both halves would look the same. If one half of the mole looks significantly different from the other, it may be a cause for concern.

B: Border

• The edges of a benign mole are typically smooth and even. If the borders of a mole are irregular, jagged, or blurred, this could be a sign of skin cancer. Moles with uneven or poorly defined borders should be examined by a dermatologist.

C: Colour

• A mole should generally have a uniform colour, such as brown, tan, or black. Moles that show a variety of colours or shades, including red, white, blue, or black, could be suspicious. Changes in colour over time are also a potential red flag.

D: Diameter

• Most benign moles are small in size, typically less than 6 millimetres in diameter (about the size of a pencil eraser). Moles that are larger than this or that have grown over time should be examined by a healthcare professional.

E: Evolving

• The most important sign of a potentially dangerous mole is change. If a mole starts to change in size, shape, colour, or texture, or if it begins to itch, bleed, or become tender, it’s essential to seek medical advice. Any evolution in a mole’s appearance could indicate the development of skin cancer.

Other Signs of Suspicious Moles and Skin Changes

In addition to the ABCDE rule, there are other warning signs to watch for when examining your skin:

• New Moles: If you notice a new mole appearing after the age of 30, it’s important to have it checked by a dermatologist. While most new moles are harmless, it’s always better to be cautious.

• Bleeding or Oozing: Moles that bleed, ooze, or develop a crust may be indicative of skin cancer. Healthy moles typically do not have these characteristics.

• Itching or Tenderness: If a mole becomes itchy, tender, or painful, this could be a sign of something more serious and warrants further investigation.

• Moles with a Shiny or Pearly Surface: Basal cell carcinoma, a common type of skin cancer, often appears as a shiny or pearly bump on the skin. If you notice any lesions with these characteristics, seek a professional evaluation.

• Sores That Don’t Heal: A sore that doesn’t heal within a few weeks could be a sign of skin cancer. This is particularly true for lesions that heal and then re-open.

If you notice any of the above signs, it’s important to schedule an appointment with a dermatologist. Early detection is critical in the treatment of skin cancer, and a timely consultation could make all the difference. At iQonic, our experienced surgeons use advanced tools to assess suspicious moles with precision and accuracy, ensuring the best course of action for diagnosis and treatment.

In some cases, a biopsy may be required to determine whether a mole is cancerous. This involves removing a small sample of tissue for laboratory testing. If skin cancer is detected, your dermatologist will discuss treatment options with you, which may include mole removal or further surgical procedures.

How to Protect Your Skin from Skin Cancer

While monitoring your moles is essential, prevention is equally important. Taking steps to protect your skin from harmful UV radiation can significantly reduce your risk of developing skin cancer. Here are a few tips:

• Wear Sunscreen: Use broad-spectrum sunscreen with an SPF of 30 or higher every day, even on cloudy days.

• Avoid Tanning Beds: The UV radiation from tanning beds can increase your risk of skin cancer.

• Wear Protective Clothing: When spending time outdoors, wear a wide-brimmed hat, sunglasses, and clothing that covers your skin.

• Seek Shade: Avoid being in direct sunlight during peak hours (10 a.m. to 4 p.m.).

• Reapply Sunscreen: Reapply sunscreen every two hours, especially after swimming or sweating.

Identifying suspicious moles early is key to preventing the spread of skin cancer. By using the ABCDE rule and keeping an eye on other skin changes, you can take control of your skin health and seek medical attention when needed. At iQonic, we are dedicated to helping you protect and care for your skin with expert diagnostics and personalised treatments.
