Skin Cancer Warning Signs: New Moles or Changes in Existing Ones

Skin cancer is one of the most prevalent cancers in the world, and yet, many are not aware of how preventable it can be. The most important thing in beating it is through early detection. One of the most important warning signs is new moles or noticeable changes in existing ones. Knowing what to look for and when to seek medical advice makes all the difference in catching skin cancer early.

What is Skin Cancer?

Skin cancer occurs when skin cells begin to grow abnormally, typically because of extensive exposure to ultraviolet rays from the sun or tanning beds. There are three important forms:

• Basal Cell Carcinoma – The most common and least aggressive type, usually having the appearance of a shiny bump or a persistent sore.
• Squamous Cell Carcinoma – More aggressive than BCC, often appearing like patches of skin covered with scales or red ulcers.
• Melanoma – It’s the worst one, though its growth could be very rapid if not identified early, commonly beginning as changing moles.

Why Early Detection is Crucial

Skin cancers are highly treatable if recognized early. That’s why being aware of your skin and examining it regularly for new or changing spots is so important. The sooner you notice anything unusual, the better your chances of treatment success.

The ABCDE Rule: A Simple Guide for Spotting Skin Cancer

Doctors often use the ABCDE rule as a guide in identifying moles that might be cancerous:

• A – Asymmetry: One half of the mole doesn’t resemble the other.
• B – Border: The edges are jagged, notched, or blurry.
• C – Color: The mole has different shades of brown, black, red, white, or blue.
• D – Diameter: It is greater than 6mm (about the size of a pencil eraser).
• E – Evolving: The mole changes over time in one or more of the above ways.

If you notice any of these signs, it’s best to get checked by an oncologist.

Should You Be Concerned About a New Mole?

Moles can appear at any age, but if a new one develops in adulthood, it’s worth keeping an eye on. You should be concerned if:

• It looks different from your other moles (sometimes called an “ugly duckling” mole).
• It’s growing quickly or changing in shape.
• It becomes itchy, painful, or starts to bleed.

What About Changes in Existing Moles?

Even moles you’ve had for years can turn cancerous. Look out for these changes:

• Getting darker or lighter suddenly
• Becoming raised or developing an uneven texture
• Forming a crust or scab that doesn’t heal
• Bleeding without any injury

Other Skin Cancer Warning Signs

Besides moles, other unusual skin changes could indicate skin cancer:

• A sore that doesn’t heal
• A scaly or rough area that does not go away
• A patch that itches, hurts, or is sensitive to touch for no apparent reason.

Who is Most at Risk for Skin Cancer?

Some people are more likely than others to get skin cancer, such as those who:

• Spend a lot of time in the sun without protection.
• Have fair skin, freckles, or light-colored hair.
• Have a family history of skin cancer.

Easy Ways to Reduce Your Risk

1. Always Use Sunscreen

A broad-spectrum sunscreen with SPF 30 or higher protects against both UVA and UVB rays. Apply it daily, even when it’s cloudy.

2. Cover Up

Wear long sleeves, wide-brimmed hats, and sunglasses to shield yourself from the sun.

3. Avoid Peak Sun Hours

Try to stay in the shade between 10 AM and 4 PM, when the sun’s rays are the strongest.

4. Do Regular Skin Checks

Inspect your skin each month to find any new or changing moles. If you notice something is off, book an appointment with a dermatologist.

5. Avoid the Tanning Beds

Exposure to artificial UV rays can be as damaging as direct sunlight and drastically raises your chances of getting skin cancer.

How is Skin Cancer Diagnosed?

If you or your physician suspect a cancerous mole, additional testing might include:

• Biopsy: Removing a sample of the mole to test for cancerous cells.
• Imaging Tests: In case the worry is that it may have already spread.

What Are the Treatments?

The type of skin cancer as well as stage determine treatment options but may include all or any of the following:

• Surgical Removal: Taking out the carcinogenic area plus some healthy tissue.
• Mohs micrographic Surgery: A technique that removes the cancer layer by layer, keeping as much healthy skin intact.
• PDEMA (Peripheral and Deep en face margin assessment): The surgeon removes a thin layer of skin, including the tumor. This layer is frozen, stained, and examined with a microscope for cancer cells. If cancer cells are found, another layer is removed and examined. This process is continued until the skin samples are found to be free of cancer.
• Cryotherapy: Freezing and killing abnormal cells.
• Topical Treatments: Medication applied directly to the skin in early stages of cancer.
• Radiation or Immunotherapy: Applied for more advanced stages.

One of the most preventable types of cancer is skin cancer, and yet it’s often ignored until it’s too late. You can catch potential problems early by paying attention to new moles or changes in existing ones, using sun protection, and getting regular skin checks. If you notice something unusual, don’t wait—see a doctor and take charge of your skin health today!
