I remember a patient, let’s call him John, a keen gardener, who came in a while back. He’d noticed a tiny, pearly bump on the rim of his ear. “Doc,” he said, “it’s been there for months, sometimes it itches, sometimes it even bleeds a bit if I scratch it.” He’d almost dismissed it. That little bump? It turned out to be an early sign of skin cancer on ear. It’s more common than you might think, especially on that outer part that catches so much sun.
The good news is, when we catch it early, we can often treat it very effectively. But if it’s left to its own devices, it can, unfortunately, spread.
So, What Exactly Is Skin Cancer on the Ear?
Simply put, skin cancer on the ear is when skin cells on your ear start growing abnormally and out of control. It usually shows up on the outer ear, the part we see.
There are a few main types we look out for:
- Basal cell carcinoma: This is a common one. Often looks like a waxy bump or a flat, flesh-colored or brown scar-like lesion.
- Squamous cell carcinoma: This is actually the most frequent type found on the outer ear. It might appear as a firm, red nodule or a flat lesion with a scaly, crusted surface.
- Melanoma: This is the one we worry about most because it’s more likely to spread if not caught early. It can develop from an existing mole or appear as a new, unusual-looking spot.
While melanoma is less common overall, it’s the most serious because it has a higher chance of spreading to other parts of your body, making it tougher to treat.
What Should You Be Looking For?
The biggest clue is a change in the skin on your outer ear. It might be subtle at first. Here’s what I tell my patients to keep an eye out for:
- A sore or a mole that changes how it looks.
- A patch of skin that’s discolored.
- A spot that’s itchy or bleeds for no clear reason.
- A pinkish lump that feels hard and has a scaly top.
- A shiny bump or nodule.
- A sore that just won’t heal, even after four weeks.
- An area that looks like a scar, maybe yellowish or white, but you don’t remember an injury.
We often use the ABCDE guideline in the clinic. It’s a handy way to check moles or spots:
- Asymmetry: One half doesn’t match the other.
- Border: The edges are irregular, ragged, or blurred.
- Color: The color isn’t the same all over; it might have shades of brown or black, sometimes with patches of pink, red, white, or blue.
- Diameter: The spot is larger than about 6 millimeters across (roughly the size of a pencil eraser), though melanomas can sometimes be smaller when first detected.
- Evolution: The mole is changing in size, shape, color, or symptoms like itching or bleeding.
What Causes It, and Am I at Risk?
The main culprit? Sunshine. Or more specifically, the ultraviolet (UV) light from the sun. Our ears, especially the tops and backs, get a lot of sun exposure, often without us realizing it. These UV rays can damage the DNA in our skin cells. When that happens, cells can start to grow abnormally, becoming cancerous. If you’ve had sunburns, especially blistering ones, your risk goes up.
Other things that can increase your risk include:
- Your features: Having fair skin that freckles or burns easily, blond or red hair, or light-colored eyes.
- Moles: Having many moles or moles that look unusual.
- Family history: If skin cancer runs in your family.
- Medical history: Things like having had an organ transplant, undergoing UV light therapy for conditions like eczema or psoriasis, or having actinic keratosis (those rough, scaly, dark pink-to-brown precancerous spots).
- Weakened immune system: Certain medications can weaken your body’s defenses.
- Lifestyle: Spending a lot of time outdoors, living in a sunny or high-altitude place, or using tanning beds (a big no-no from my perspective!).
- Chemical exposure: Less commonly, contact with substances like tar and coal can be a factor.
How Do We Figure This Out? Diagnosis and Tests
If you come to see me, or a dermatologist, with a suspicious spot on your ear, here’s generally what happens:
- Physical Exam: First, we’ll take a really good look at your ear. I’ll ask you about the spot – when you noticed it, if it’s changed, any symptoms.
- Biopsy: If a spot looks concerning, the best way to know for sure is a biopsy. This sounds scarier than it usually is. We numb the area and take a tiny sample of the skin. This sample then goes to a lab where a pathologist (a doctor who specializes in looking at cells and tissues) examines it under a microscope to check for cancer cells.
- Imaging: If the biopsy confirms cancer, especially if it’s a type that might spread or seems a bit deeper, we might suggest an MRI or CT scan. These pictures help us see if the cancer has spread and how far, which is really important for planning the best treatment.
Treating Skin Cancer on the Ear
Our main goal is to get rid of the cancer cells while keeping as much of your healthy ear tissue as possible. The treatment we recommend will depend on the type of skin cancer, its size and location, and its stage (from Stage 0, meaning it’s just on the surface, to Stage IV, meaning it has spread).
Sometimes, for very early, superficial skin cancers, the biopsy itself might remove all of it. How great is that?
For others, we might use:
- Excisional surgery: The surgeon carefully cuts out the cancerous lesion along with a small margin of normal-looking skin around it, just to be sure all the cancer cells are gone.
- Curettage and electrodesiccation: This involves scraping away the cancer with a special tool (curette) and then using an electric needle to treat the base, destroying any remaining cancer cells.
- Mohs surgery: This is a very precise technique, often used for cancers in tricky areas like the ear, or for larger or recurrent cancers. The surgeon removes the visible cancer and then removes very thin layers of skin, one at a time. Each layer is immediately checked under a microscope. They keep going until no more cancer cells are seen. This helps save as much healthy tissue as possible.
Other Treatment Avenues
Besides surgery, especially if the cancer is more advanced or surgery isn’t the best first step, we might talk about:
- Chemotherapy: Using drugs to kill cancer cells, sometimes as a topical cream for very superficial cancers.
- Cryotherapy: Freezing the cancer cells.
- Immunotherapy: Helping your own immune system fight the cancer.
- Photodynamic therapy: Using a special drug and light to kill cancer cells.
- Radiation therapy: Using high-energy rays to destroy cancer cells.
We’ll always discuss all the options with you, making sure you understand the pros and cons for your specific situation.
Can it Spread to the Brain?
It’s a serious question. Yes, if skin cancer on the ear isn’t diagnosed and treated, it can grow deeper and potentially spread. Once cancer cells get into the bloodstream or the lymph system (which helps drain fluid), they can travel to other parts of the body, and that can include the brain. This is why catching it early is so, so important.
Is It Curable?
Yes, in many cases, especially when found early. When skin cancer on the ear is in its lower stages, treatment is often very successful. If it has spread, it becomes more complex, and success depends on where and how much it has spread.
What’s the Outlook?
Generally, pretty good if we catch it early! Most skin cancers on the ear can be cured if they’re found before they spread.
For melanoma on the ear, the outlook is tied to how early it’s detected. The five-year survival rates give us an idea:
- Around 99% if it’s found before it spreads to lymph nodes.
- About 66% if it has spread to nearby lymph nodes.
- Roughly 27% if it has spread to distant lymph nodes and other organs.
These are just statistics, of course, and every person’s journey is unique.
Protecting Your Ears: Prevention is Key
You can do a lot to lower your risk!
- Sunscreen, sunscreen, sunscreen! I can’t say it enough. So many folks remember their face but forget their ears. Use a broad-spectrum sunscreen (SPF 30 or higher) and apply it generously to your ears. And reapply, especially if you’re sweating or swimming. Even on cloudy days!
- Seek shade: Especially during the peak sun hours (usually 10 a.m. to 4 p.m.).
- Hats are your friends: A wide-brimmed hat can offer great protection for your ears, face, and neck.
- Avoid tanning beds: Just don’t. The UV radiation is intense and damaging.
- Check your skin: Get to know your skin, including your ears. It’s tricky to see your own ears well, so use a mirror, or better yet, ask a loved one to take a look for you regularly. Your phone camera can be surprisingly helpful too!
When to Ring Me or a Dermatologist?
It’s always a good idea to have a dermatologist check your skin annually, especially if you have risk factors. But definitely make an appointment if you notice:
- Any changes to the skin on your ear, or to existing moles.
- A new growth.
- A sore that isn’t healing.
- Any unusual spots, or areas that itch or bleed.
Basically, if something on your ear skin looks or feels off, or if it’s new and worrying you, get it checked. Better safe than sorry, truly.
Questions for Your Doctor’s Visit
If you are diagnosed, it’s natural to have a million questions. Don’t hesitate to ask. Here are some you might consider:
- What kind of skin cancer do I have on my ear?
- What stage is it?
- Will I need more tests?
- What are my treatment options, and what do you recommend for me?
- What are the potential side effects of that treatment?
- How will I feel during treatment?
- What’s the long-term outlook for me?
- Am I at higher risk for other skin cancers now?
- How often should I have follow-up appointments?
