Bumps & Growths on Skin: Atypical Moles, Seborrheic Keratoses & Skin Cancer Warning Signs
Finding a new bump or growth on your skin can be alarming. Most are benign, but some signal skin cancer or precancerous changes. Common non-cancerous growths include seborrheic keratoses (waxy, stuck-on “age warts”) and atypical moles (dysplastic nevi), while suspicious ones may indicate basal cell carcinoma, squamous cell carcinoma, or melanoma. Professional evaluation is essential for peace of mind and early detection.
Common Types of Bumps & Growths
- Seborrheic Keratoses: Waxy, brown/black, stuck-on appearance. Harmless and very common with age. Can be removed for cosmetics or irritation.
- Atypical Moles (Dysplastic Nevi): Irregular shape, color variation, larger than normal moles. Increase melanoma risk—especially with personal/family history of skin cancer.
- Skin Cancer Signs: Non-healing sores, changing moles, pearly/translucent bumps (BCC), scaly/red patches (SCC), or asymmetrical, multicolored moles (melanoma).
Use the ABCDE rule for moles: Asymmetry, Border irregularity, Color variation, Diameter >6mm, Evolving.
When to Seek Evaluation
See a dermatologist promptly for:
- Rapidly changing or growing lesions
- Bleeding, itching, or painful growths
- New bumps after age 40
- Personal history of skin cancer or atypical moles
Early biopsy can rule out malignancy.
Treatment & Removal Options
- Cryotherapy or curettage for benign growths
- Surgical excision or shave removal
- Laser for cosmetic concerns
- Full skin exams for high-risk patients
Most removals are quick in-office procedures with excellent cosmetic results.
Prevention Tips
- Monthly self-exams using mirrors
- Annual professional skin checks (more frequent if high-risk)
- Daily broad-spectrum SPF 30+ and sun-protective clothing
- Avoid tanning beds
