Most of us have moles we’ve never given a second thought to. That’s normal — the average adult has somewhere between 10 and 40 of them. But every once in a while, a spot changes in a way that matters, and knowing what to look for can genuinely save your life.
At Advanced Dermatology & Cosmetic Surgery Center, we tell patients the same thing over and over: melanoma is one of the most serious skin cancers out there, but it’s also one of the most treatable — if you catch it early. The trick is knowing what “catch it early” actually looks like on your own skin.
That’s where the ABCDE guide comes in.
The ABCDEs of Melanoma
Dermatologists use this simple checklist to help patients tell a normal mole from one that needs a closer look. You don’t need any special training to use it – just a mirror, good lighting, and a few minutes.
A is for Asymmetry Draw an imaginary line through the middle of a mole. If the two halves don’t match, that’s worth noting. Normal moles tend to be fairly symmetrical.
B is for Border Healthy moles usually have smooth, even edges. Melanoma often has borders that are ragged, notched, or blurred.
C is for Color One shade of brown is typical for a benign mole. A mole with several colors – shades of brown, black, tan, red, white, or even blue – is a red flag.
D is for Diameter Melanomas are often larger than the eraser on a pencil (about 6mm), though they can be smaller when caught early. Any mole that’s growing is worth a look, regardless of size.
E is for Evolving This one might be the most important letter. Any mole that’s changing – in size, shape, color, or texture, or that starts to itch, bleed, or crust – should be checked out, even if it doesn’t tick any of the other boxes.
If a spot on your skin checks even one of these boxes, don’t wait it out. Come see us.
What Melanoma Can Look Like
Melanoma develops in melanocytes, the cells that give your skin its color. It can show up as a dark brown, black, or multi-colored growth with irregular edges, and in more advanced cases it may become crusted or start to bleed. Sometimes it grows out of a mole you’ve had for years. Other times, it appears out of nowhere on skin that looked perfectly clear the week before.
It can affect anyone, at any age, anywhere on the body. Your risk goes up if you have fair skin, light hair or eyes, a family history of melanoma, or a personal history of it. But melanoma doesn’t only affect people with fair skin – patients with darker complexions can develop it too, often in places that are easy to overlook: the palms, the soles of the feet, under the nails, or inside the mouth. Those spots deserve a regular look too.
Why Early Detection Matters So Much
Melanoma can spread to other organs if it’s left untreated, which is exactly why catching it early makes such a difference. Once it’s found, treatment is tailored to you – where the tumor is, how far it’s spread, how aggressive it looks under the microscope, and your overall health. Options range from surgical excision and Mohs Micrographic Surgery to chemotherapy or radiation in more advanced cases, and sometimes nearby lymph nodes need to be checked as well. Your dermatologist will walk you through what makes sense for your situation.
Protecting Your Skin Going Forward
Sun exposure, especially the kind that leads to sunburn, is the single biggest driver of melanoma – so prevention really does start outside, not just at the doctor’s office. A few habits go a long way:
- Stay out of direct sun during peak hours, roughly 10 a.m. to 4 p.m.
- Wear sunglasses, a broad-brimmed hat, and tightly woven clothing when you’re outdoors
- Apply a broad-spectrum SPF 30+ sunscreen to all exposed skin, lips included, and reapply often – cloudy days count too
- Skip the tanning bed — if you love a bronzed look, try a spray tan instead. It’s UV-free, so you get color without the wrinkles, sun damage, or added skin cancer risk
And beyond sun protection, get in the habit of checking your own skin regularly, then let us take it from there with a professional skin exam. Early detection is genuinely lifesaving with this disease, and it starts with knowing what your skin normally looks like so you notice when something’s off.
