Skin cancer is a growing concern worldwide, with the Skin Cancer Foundation reporting that one in five Americans will develop the disease by age 70. This translates to over 9,500 diagnoses daily in the U.S. alone. The issue is not limited to the U.S., as 170,000 people are diagnosed annually in the United Kingdom. Given its prevalence, early detection is critical. Below are five subtle skin changes that may signal the development of skin cancer.

### 1. Persistent Itchy or Dry Patches
While itchy or dry skin is often harmless and linked to conditions like eczema or psoriasis, it can sometimes indicate more serious issues, such as cutaneous T-cell lymphoma, a rare form of cancer. These patches may persist for years, becoming scaly, painful, and changing in texture. Additionally, basal cell carcinoma, one of the most common types of skin cancer, can cause persistent itching. Other underlying causes of itchy skin include diabetes, liver disorders, or kidney disease. If topical treatments don’t resolve the issue, consult a dermatologist.

### 2. New or Changing Moles or Lesions
Monitoring moles and lesions is crucial for early detection of melanoma, a dangerous form of skin cancer. Warning signs include changes in color, size, or shape, as well as irregular borders. While many moles are benign, those resembling melanoma may increase your risk of skin cancer. Genetics also play a role, so if you have a family history of melanoma, regular skin checks are essential. Early detection and removal of suspicious moles can significantly improve outcomes.

### 3. Sudden Skin Discoloration
Unexpected changes in skin color, such as red, yellow, or dark patches, may indicate underlying health issues. Yellow skin can signal liver disease, while redness may point to lupus or rosacea. Dark patches, particularly on the neck or underarms, could be a sign of acanthosis nigricans, often linked to hormonal imbalances or diabetes. Certain medications, like birth control pills or chemotherapy drugs, can also cause hyperpigmentation. Nutritional deficiencies, such as a lack of vitamin B12, may contribute to these changes as well.

### 4. Non-Healing Wounds
Sores that bleed, reopen frequently, or fail to heal within two weeks could be early signs of basal cell carcinoma or squamous cell carcinoma. These cancers often present as red patches, open sores, or crusted growths. Slow-healing wounds may also be a symptom of diabetes, where poor circulation impairs the body’s ability to repair skin. The American Cancer Society advises seeking medical attention for sun-exposed wounds that don’t heal promptly, as chronic wounds can lead to infections like cellulitis or even sepsis.

### 5. New Bumps or Growths
The sudden appearance of lumps, scaly patches, or raised areas should not be ignored, even if they seem minor. Dermatologists warn that irregular borders or rapid growth are red flags. While benign growths are common with aging, any unusual changes should be evaluated by a professional. New bumps could also result from infections like HPV, so it’s important to have them checked promptly.

### The Bottom Line
Skin changes can stem from various factors, including aging, infections, or underlying health conditions. While many are harmless, it’s crucial to monitor any new or unusual developments. If you notice persistent itching, changing moles, discoloration, non-healing wounds, or new growths, schedule an appointment with a dermatologist or healthcare provider. Early detection and treatment can make a significant difference in outcomes. Stay vigilant and prioritize your skin health.
