Skin changes are easy to dismiss, especially when a spot has been present for months or looks like a minor irritation. In the Southwest, however, frequent sun exposure can increase the risk of skin damage over time. A new growth, changing mole, or sore that does not heal may deserve more attention than another over-the-counter cream.
Knowing which warning signs to watch can help you seek an evaluation before a potentially serious problem becomes more difficult to treat.
Watch for Changes in Moles and Growths
Many skin cancers begin as a spot that looks different from the surrounding skin. A useful way to assess a mole is the ABCDE approach:
- Asymmetry: One half does not match the other.
- Border: The edges are uneven, blurred, or irregular.
- Color: The spot contains multiple shades, including black, brown, red, blue, or white.
- Diameter: The growth is larger than about 6 millimeters, roughly the size of a pencil eraser.
- Evolving: The mole changes in size, shape, color, texture, or symptoms.
The “evolving” sign is particularly important. A mole does not need to meet every ABCDE characteristic to warrant an evaluation. A spot that begins itching, bleeding, crusting, or becoming tender should be checked, especially if those symptoms continue.
Not every unusual mole is cancerous, but visual inspection alone cannot always provide a reliable answer. A professional evaluation may include a close examination with magnification and, when appropriate, a biopsy to identify the type of cells involved.
Do Not Ignore Persistent Skin Problems
Skin cancer does not always look like a classic dark mole. Some cancers appear as firm, shiny, or pearly bumps. Others may resemble a rough patch, a scaly area, or a recurring sore.
Signs that deserve attention
Schedule an evaluation if you notice:
- A sore that has not healed after several weeks
- Repeated bleeding from the same spot
- A rough patch that continues to return
- A growth that feels firm or scaly
- A shiny bump with visible blood vessels
- A reddish or brown area that gradually expands
- A lesion that becomes painful, itchy, or crusted without a clear cause
Sun-damaged areas may also develop actinic keratoses, which are rough, precancerous growths caused by cumulative ultraviolet exposure. These spots are not always cancer, but some can progress if left untreated. Finding one may also indicate broader sun damage and a need for more regular skin checks.
Why Southwest Sun Exposure Raises the Stakes
Residents in Arizona, Nevada, Utah, New Mexico, and nearby areas may face intense sunlight for much of the year. Outdoor work, hiking, sports, construction, driving, and recreational activities can all add to cumulative ultraviolet exposure—even when the weather feels mild or cloudy.
Sunburn is not the only concern. Repeated lower-level exposure can also contribute to premature skin aging, rough texture, discoloration, and cellular damage over time. People with fair skin, a history of sunburns, many moles, or a close family history of skin cancer may need to be especially attentive.
A professional evaluation through Southwest Skin and Cancer can help determine whether a suspicious area should be monitored, treated, or biopsied. It can also give you a clearer plan for future screenings based on your personal risk factors.
What to Expect During an Evaluation
A skin cancer evaluation usually begins with a review of your medical history, sun exposure, previous skin conditions, and any changes you have noticed. The clinician may examine the entire skin surface or focus on a specific lesion, depending on your concerns and risk level.
If a spot appears suspicious, the next step may be a biopsy. This typically involves removing a small sample of tissue for laboratory analysis. The result can identify whether the lesion is benign, precancerous, or cancerous and can guide the appropriate treatment.
Do not wait for a spot to become painful before asking about it. Many early skin cancers cause little or no discomfort. A changing appearance, persistent sore, or unusual new growth is often a more meaningful warning sign than pain.
Regular self-checks, sun-protective clothing, broad-spectrum sunscreen, and prompt attention to changes can reduce the chance that a concerning lesion goes unnoticed. When something looks different from the rest of your skin and stays that way, professional evaluation is the practical next step.
