Most people associate skin cancer with excessive sun exposure, beach days without sunscreen, or tanning beds. While it’s true that UV radiation is a leading cause of skin cancer, it’s not the whole story. Skin cancer can—and does—appear on parts of the body that rarely, if ever, see sunlight. This surprising fact often leaves patients puzzled and concerned. At Station Road Medical Centre, our experts at the skin cancer clinic Ipswich encounter such cases more frequently than you might think.
Understanding why this happens and how to stay protected, even in places you wouldn’t expect, is vital for your overall health and peace of mind.
What is Skin Cancer?
Skin cancer is the abnormal growth of skin cells. It usually develops on skin exposed to the sun, but it can also occur in areas not typically exposed. There are three primary types:
-
Basal cell carcinoma (BCC) – Most common and least dangerous
-
Squamous cell carcinoma (SCC) – More aggressive than BCC, but treatable
-
Melanoma – The most serious form; can spread to other organs quickly if not detected early
While UV radiation is the primary risk factor, genetics, immune function, and environmental exposures also play critical roles.
Can You Really Get Skin Cancer in Sun-Protected Areas?
Yes, you can. Skin cancer can develop anywhere on the body—including areas that receive little to no sunlight. Common sun-protected areas where skin cancer might appear include:
- Under the nails
- Soles of the feet
- Palms of the hands
- Genital area
- Inside the mouth
- Between the toes
- Scalp (particularly under thick hair)
This reality is especially true for melanoma, the deadliest form of skin cancer. Acral lentiginous melanoma, a subtype, typically appears on the palms, soles, and under the nails, particularly among people with darker skin.
Causes Beyond the Sun:
If not sun exposure, then what? Several other factors can increase your risk of developing skin cancer in sun-protected areas:
1. Genetics
A family history of melanoma or other skin cancers significantly increases your risk. Certain gene mutations are inherited and may predispose a person to develop skin cancer regardless of sun exposure.
2. Weakened Immune System
Those with compromised immune systems—such as organ transplant recipients or individuals undergoing cancer treatments—have a higher likelihood of developing skin cancer, including in unexpected areas.
3. Exposure to Toxins
Long-term exposure to certain chemicals, such as arsenic or coal tar, can cause skin cancer without the need for UV light.
4. HPV and Other Viruses
Certain types of human papillomavirus (HPV) have been linked to the development of squamous cell carcinoma, particularly in the genital and anal areas.
5. Chronic Inflammation or Scarring
Skin that is constantly irritated or scarred from burns, infections, or chronic conditions can develop cancerous changes over time.
Warning Signs in Hidden Places:
Because we rarely inspect less visible areas of our body, skin cancer in these locations often goes undetected until it has progressed. You should be alert to:
- Dark streaks under nails
- Sores that don’t heal
- Lumps or growths with irregular borders
- New pigmentation in the genital or anal area
- Unexplained bleeding or pain in moles or skin lesions
Performing regular self-checks and scheduling annual skin exams are key, especially if you have a history of skin issues or risk factors.
How Are These Cancers Diagnosed?
Diagnosing skin cancer in less visible areas is challenging because symptoms can mimic other conditions like fungal infections, bruises, or benign moles. However, at our skin cancer clinic Ipswich, our experienced doctors are trained to distinguish and investigate any suspicious changes.
Typical diagnostic methods include:
- Visual inspection – A thorough skin examination
- Dermatoscopy – A specialized magnifying tool for a closer look
- Biopsy – Taking a small sample of the skin to examine for cancer cells
If detected early, treatment is often straightforward and highly successful.
Treatment Options:
Skin cancer treatments vary based on the type, location, and stage of the cancer. Options include:
- Surgical excision – Removing the cancerous lesion and a margin of healthy tissue
- Cryotherapy – Freezing abnormal cells with liquid nitrogen
- Topical medications – For superficial cancers
- Radiation therapy – In certain non-surgical cases
- Immunotherapy – For advanced melanoma cases
The team at Station Road Medical Centre will guide you through the most suitable treatment plan with compassion and expertise.
Prevention Strategies for All Areas of the Body:
Protecting your skin isn’t just about avoiding sunburn. You should also take measures to guard your overall skin health:
- Wear sunscreen daily, even in winter or cloudy weather
- Check hard-to-see places with the help of a mirror or partner
- Moisturize to avoid cracking and chronic skin irritation
- Use non-irritating, chemical-free personal care products
- Avoid tanning beds and UV-emitting devices
Regular skin checks by professionals are essential, particularly for people at high risk. Even if you feel healthy, subtle changes might signal early skin cancer.
Why You Shouldn’t Delay Your Skin Check?
Many people ignore or postpone skin checks, especially if they don’t spend much time in the sun. But remember, skin cancer can affect anyone, anywhere, regardless of sun exposure. Early detection makes all the difference—both in outcomes and peace of mind.
At our trusted skin cancer clinic Ipswich, we offer comprehensive full-body skin checks, professional advice, and personalised care.
When to See a Doctor?
Seek medical advice if you notice:
- Any new or changing moles or growths
- Persistent itching, bleeding, or pain in a specific skin area
- Dark spots under nails or around the mouth/genital area
- Skin that doesn’t heal after weeks
You don’t need to wait for a problem to appear. Regular screenings can catch early changes before they become serious.
