Age spots, also known as solar lentigines, are very common. You’ve probably seen them on your face, hands, or arms. These spots are usually harmless blemishes caused by sun exposure and excess melanin production.
Melanoma, on the other hand, is a serious form of skin cancer. It can be life-threatening if it’s not detected and treated early. Melanoma is often characterized by irregular borders and changes in size, color, or shape. It’s critical to keep an eye on them.
The goal of this article is to help you tell the difference between melanoma vs age spots, providing you with the information you need to identify them. We’ll also discuss risk factors, prevention strategies, and when it’s time to seek medical advice.
What are age spots?
Age spots are flat spots that are tan, brown, or black. They tend to appear on skin that gets a lot of sun exposure. You may also hear them called liver spots or solar lentigines. They’re usually painless, and they often cluster together.
The good news is that age spots are benign, so they don’t pose a health risk on their own. However, many people don’t like the way they look.
Causes and risk factors
Too much sun exposure and UV radiation are the primary culprits behind age spots. When your skin is exposed to UV radiation, it stimulates melanocytes to make more melanin. Melanin is the pigment that gives your skin its color.
Other factors that can contribute to age spots include genetics, hormonal changes, and artificial UV radiation from tanning beds. Even a little time in a tanning bed can lead to age spots.
What is melanoma?
Melanoma is a type of skin cancer that develops in melanocytes, the cells that produce melanin, which gives our skin its color.
Melanoma tends to be more aggressive than other forms of skin cancer, and if it isn’t caught and treated early, it can be life-threatening.
Melanoma can appear anywhere on your body. Keep an eye out for new moles or changes to existing moles, as those can be signs of melanoma.
Risk factors for melanoma
The biggest risk factor for melanoma is sun exposure, especially intermittent, intense exposure, such as the kind you get when you’re sunburned. In fact, research shows that having five or more sunburns doubles your risk for melanoma.
Other risk factors include:
- Fair skin
- Family history of melanoma
- History of severe sunburns
- Having a large number of moles

Key Differences Between Age Spots and Melanoma: A Comparative Analysis
So, how can you tell the difference between a harmless age spot and a potentially dangerous melanoma? Here’s a breakdown of the key differences to look for:
Visual Appearance
Age spots tend to be:
- A single, uniform color (tan, brown, or black)
- Round or oval
- Smooth
- Smaller in size
- Have well-defined borders
Melanomas, on the other hand, often exhibit the “ABCDEs” of melanoma:
- Asymmetry: One half of the spot doesn’t match the other half.
- Border: The edges are ragged, notched, or blurred.
- Color: There are multiple colors within the same spot, such as black, brown, tan, red, or blue.
- Diameter: The spot is often larger than 6mm (about the size of a pencil eraser).
- Evolution: The spot is changing in size, shape, color, or elevation.
Texture and Elevation
Age spots are usually flat and smooth to the touch. You might not even notice them unless you’re specifically looking for them.
Melanomas can be raised, scaly, or have an irregular texture. They may also be itchy, bleeding, or crusting.
Evolution and Growth Pattern
Age spots typically remain stable in size and appearance over time. They might fade slightly, but they generally don’t change dramatically.
Melanomas are characterized by changes. If you notice a mole or spot that’s rapidly growing, changing color, or becoming raised, it’s essential to get it checked out by a dermatologist right away. Any noticeable change should be a cause for concern.
How to Spot a Problem: The ABCDEs of Melanoma
The ABCDE rule is a helpful guide for figuring out whether a mole might be melanoma.
- A is for Asymmetry. Is one half of the mole different from the other?
- B is for Border irregularity. Are the edges of the mole uneven, notched, or blurry?
- C is for Color variation. Does the mole have a variety of colors, such as black, brown, and tan?
- D is for Diameter. Is the mole larger than 6 millimeters, about the size of a pencil eraser?
- E is for Evolving. Is the mole changing in size, shape, or color?
It’s important to note that the ABCDE rule isn’t foolproof. Some melanomas can be small and might not have all of these characteristics.
Other warning signs to watch out for include:
- New moles that look different from your other moles (the “ugly duckling” sign)
- Any mole that itches, bleeds, or develops a crust
- A sore that doesn’t seem to heal
Prevention strategies and early detection
Whether you’re trying to prevent age spots or melanoma, there are a few things you can do to protect yourself.
Sun protection
Sunscreen is your friend. Use a broad-spectrum sunscreen with an SPF of 30 or higher every day, even when it’s cloudy. Reapply every couple of hours, especially after you’ve been swimming or sweating.
Also, wear protective clothing when you can, like long sleeves, hats, and sunglasses. Try to stay out of the sun during the peak hours of 10 a.m. to 4 p.m.
And definitely avoid tanning beds. There’s just no such thing as a “safe tan” from a tanning bed.
Regular self-exams
Check your skin once a month for any new or changing moles. Use a full-length mirror and a hand mirror to check all areas of your body, including those hard-to-see spots like your scalp, the soles of your feet, and under your nails.
If you notice any changes in your moles or spots, document them. Take photos so you can monitor them over time and show them to your doctor at your next appointment. The sooner you catch something, the better.
When should I see a doctor?
You should always see a dermatologist if you notice a suspicious change to your skin, like a new mole, a change in an existing mole, or any of the ABCDE warning signs. A dermatologist can examine your skin and figure out if you need a biopsy.
The earlier you catch skin cancer, the better. If you’re worried about a spot on your skin, it’s always a good idea to get it checked out.
Dermatologists can also diagnose age spots with an examination and, if needed, a biopsy.
Frequently Asked Questions
What does stage 1 melanoma look like?
Stage 1 melanoma is typically thin (usually less than 1 millimeter thick) and may or may not be ulcerated. It often appears as an irregular mole with uneven borders, color variations, and a diameter greater than 6 millimeters. However, visual appearance alone isn’t enough for diagnosis; a biopsy is crucial.
How to tell the difference between skin cancer and aging skin?
Differentiating between skin cancer and aging skin requires careful observation. Aging skin often shows wrinkles, dryness, and age spots (lentigos). Skin cancer, on the other hand, presents as new or changing moles or lesions that may bleed, itch, or crust over. The “ABCDEs” of melanoma (Asymmetry, Border irregularity, Color variation, Diameter greater than 6mm, Evolving) can be helpful, but professional evaluation is always best.
How to tell the difference between sunspots and skin cancer?
Sunspots (solar lentigines) are flat, evenly colored tan or brown spots caused by sun exposure. They typically have well-defined borders and uniform color. Skin cancer, particularly melanoma, often exhibits irregular borders, uneven color distribution, and may grow or change over time. Any suspicious or changing spots should be evaluated by a dermatologist.
How can you tell the difference between age spot and melanoma?
Age spots (solar lentigines) are typically flat, evenly colored, and have well-defined borders. Melanoma, however, often presents with irregular borders, uneven color, asymmetry, and may be raised or changing in size. The ABCDEs of melanoma are a useful guide, but a dermatologist’s examination and biopsy are the most reliable ways to differentiate between the two.
Putting It All Together
Age spots and melanoma can look similar, but they are very different. Age spots are a cosmetic issue, while melanoma is a dangerous form of skin cancer. Learning to tell the difference between the two is crucial for protecting your health.
The best way to stay safe is to practice sun protection every day and conduct regular skin self-exams. If you notice any changes to your skin, it’s always best to check with a dermatologist. They can evaluate any suspicious spots and provide appropriate treatment if necessary.
Remember, early detection is key when it comes to melanoma. Don’t hesitate to seek professional advice if you have any concerns about your skin. It could save your life.
