Skin Cancer Screening Portland: What Primary Care Catches and When to Escalate

Tom mentioned a small spot on his shoulder during his annual physical at Northwest Primary Care. He had noticed it months earlier but assumed it was nothing. His provider examined it under good lighting, used a dermatoscope to look more carefully, and recommended a referral to dermatology for biopsy. The result came back as an early melanoma. The treatment was a minor excision with clean margins. Caught a year later, the treatment would have been very different.

Skin cancer screening is one of the most underused parts of primary care. Many Portland-area adults assume the Pacific Northwest’s overcast reputation means low skin cancer risk. The reality is different. At Northwest Primary Care, family medicine and internal medicine providers across six Portland-area clinics include skin exams as part of preventive care and coordinate with dermatology when biopsy is needed.

Key Takeaways

Here is a brief overview of what follows:

• Skin Cancer Happens in the Pacific Northwest: Cumulative UV exposure from years of outdoor recreation, plus brighter summer months than most people realize, produces real risk in Portland-area adults.
• Three Main Types Are Worth Knowing: Basal cell carcinoma, squamous cell carcinoma, and melanoma each have different patterns and risk profiles. All are highly treatable when caught early.
• Annual Skin Exams Catch Most Cases Early: A complete annual physical often includes a focused skin exam, particularly for patients with risk factors.
• The ABCDE Rule Helps Patients Self-Monitor: Asymmetry, Border irregularity, Color variation, Diameter, and Evolution over time are the features that warrant a closer look.
• SureCare Supports Uninsured Patients: Patients without insurance can ask the scheduling team about SureCare, NWPC’s discounted private pay option for primary care visits.

Why Pacific Northwest Adults Are Not Safe From Skin Cancer

Skin cancer screening is one of the most underused parts of primary care. Outdoor recreation, decades of intermittent sun exposure, and the slowly accumulated damage from countless small exposures produce real skin cancer rates in Portland, despite the region’s overcast reputation.

The myth that Portland weather protects against skin cancer misses several realities. Summer UV levels in the region are higher than many residents realize, with July and August producing UV index readings comparable to much sunnier regions. Outdoor recreation including hiking, cycling, kayaking, and skiing produces significant exposure during the seasons when residents spend time outside.

Cumulative damage matters more than acute burns. Many Portland adults built up significant sun exposure through childhood and young adult years, often in sunnier locations before moving here. The skin damage from those years continues to drive cancer risk decades later. Snow sports add another factor. Skiing and snowboarding at higher elevations produce intense UV exposure even on overcast days, with snow reflecting much of the radiation upward.

The Three Main Types

Basal cell carcinoma is the most common skin cancer overall. It typically presents as a pearly, flesh-colored or pink nodule, often on sun-exposed areas like the face, ears, and neck. Sometimes it appears as a sore that does not heal or a scaly patch. Basal cell rarely spreads beyond the original site but can grow locally and damage surrounding tissue if untreated. Surgical removal is the standard treatment and is highly effective.

Squamous cell carcinoma is the second most common type. It presents as a firm, scaly, or crusted nodule, often on sun-damaged skin. Squamous cell can spread to lymph nodes or distant sites in a small percentage of cases, particularly when located on the lip, ear, or scar tissue. Early detection and removal addresses most cases without complications.

Melanoma is less common but more concerning. It can present as a new dark spot, a changing mole, or a spot that does not look like others on your body. Melanoma can spread quickly if not caught early, making early detection critical. Early-stage melanoma is highly treatable, often with a single excision. Late-stage melanoma is much more dangerous, which is why surveillance matters.

The ABCDE Self-Check

The ABCDE rule helps patients recognize features that warrant medical evaluation. Each letter represents a feature that increases suspicion for melanoma.

A stands for Asymmetry. Normal moles are generally symmetric. Spots where one half does not match the other are more concerning.

B stands for Border. Normal moles have smooth, regular borders. Irregular, notched, or blurred borders raise concern.

C stands for Color. Most normal moles are one shade. Spots with multiple colors or shades within the same lesion warrant evaluation.

D stands for Diameter. Spots larger than six millimeters, about the size of a pencil eraser, are more likely to be concerning, though melanoma can occur in smaller lesions.

E stands for Evolution. Any spot changing in size, shape, color, or behavior over weeks to months should be examined. Bleeding, itching, or crusting in a previously stable spot also warrants attention.

A monthly self-check, particularly after a shower when your skin is exposed, helps you notice changes. New spots in adults over thirty deserve attention regardless of size.

What a Primary Care Skin Exam Looks Like

A focused skin exam at primary care covers the major sun-exposed areas including the face, scalp, ears, neck, arms, hands, chest, back, legs, and feet. For patients with elevated risk or specific concerns, a more comprehensive exam covers harder-to-see areas including the scalp, between fingers and toes, and the soles of feet.

Your provider examines spots under good lighting and may use a dermatoscope, a handheld magnifier with polarized light that reveals features not visible to the naked eye. Most spots can be evaluated clinically without requiring biopsy. Lesions that look suspicious get referred to dermatology for biopsy and definitive evaluation.

For patients with significant risk factors, your provider may recommend annual full-skin exams either in primary care or with a dermatologist. Risk factors include personal or family history of skin cancer, fair skin, history of significant sunburns, immune suppression, and outdoor occupational or recreational exposure.

When Dermatology Referral Fits

Most suspicious skin lesions get referred to dermatology for biopsy and treatment. Dermatologists have specialized training in skin cancer evaluation, perform biopsies routinely, and handle a broader range of skin treatments including Mohs surgery for certain cancer types.

For routine skin cancer surveillance in patients with significant risk factors, ongoing dermatology care is appropriate. Your primary care provider coordinates this referral and continues to manage the broader picture. The shared electronic health record across NWPC locations means dermatology notes flow back to your primary care team.

For patients without dermatology coverage or with access barriers, primary care can still evaluate and manage routine skin concerns and arrange biopsy through other channels when needed.

Prevention Matters at Any Age

Sun protection reduces future skin cancer risk even after years of past exposure. Daily sunscreen on exposed skin, sun-protective clothing during outdoor activities, hat use, and avoiding peak UV hours all contribute to lower lifetime exposure.

For adults with significant past sun damage, prevention also includes addressing existing damage. Some precancerous lesions can be treated to prevent them from progressing to cancer. Your provider identifies spots that warrant intervention before they advance.

Skin cancer screening fits well alongside other preventive screenings that your provider coordinates as part of comprehensive care. For patients with multiple chronic conditions or complex health histories, your annual physical is the natural time to build preventive screening into your care plan.

Frequently Asked Questions

How often should I get a skin cancer screening?

For most adults without significant risk factors, an annual skin check as part of the routine physical is appropriate. Patients with personal or family history of skin cancer, significant sun exposure, fair skin, or other risk factors often benefit from more frequent dermatology surveillance. Your provider can recommend the right frequency based on your specific situation.

Can my primary care provider biopsy a suspicious spot?

Most NWPC primary care providers refer suspicious lesions to dermatology for biopsy rather than performing biopsies in the primary care office. Dermatologists have specialized training in biopsy technique for skin lesions and access to the lab resources needed for definitive evaluation. The referral process is usually quick.

What should I do if I find a suspicious spot between annual visits?

Schedule a focused appointment with your primary care provider rather than waiting for your annual physical. Early evaluation of suspicious spots matters, particularly for changing or new lesions. If your provider has concerns after examining the spot, a dermatology referral happens promptly.

Does sunscreen really prevent skin cancer?

Yes. Regular sunscreen use during sun exposure significantly reduces lifetime UV damage and lowers skin cancer risk. SPF 30 or higher applied to exposed skin, reapplied every two hours during outdoor activity, and combined with sun-protective clothing produces meaningful protection. The protection is preventive going forward, but it does not undo past damage.

Are sun-exposed areas the only places skin cancer occurs?

No. Skin cancer can occur anywhere on the body, including areas that rarely see sun. Melanoma in particular can develop in less typical locations including the palms, soles, under nails, and on the back of patients who do not commonly expose those areas. A full skin check covers the less obvious areas precisely because cancer can develop there.
