Detailed Lesion Types
Seborrheic Keratosis
What causes them?
Theyre linked to aging and genetics. The skin cells (keratinocytes) produce extra pigment and keratin, leading to the stuckon look. Most people develop a few after their thirties, and they can become more numerous with age.
Are they ever dangerous?
No. They never turn into skin cancer, but they can be mistaken for melanoma because of their dark colour. Thats why the visual checklist matters.
Cherry Angioma
Why do they appear?
Theyre caused by clusters of tiny blood vessels. Hormonal changes, genetics, and even certain medications can increase their number.
Should they be removed?
Only if theyre irritating, bleed, or you simply dont like how they look. Removal is quick (usually a shave or laser) and inexpensive.
Skin Tags
Where do they like to hide?
Neck, armpits, groin, and under breastsany place where skin rubs together. Friction seems to trigger their growth.
Are they a sign of anything?
Not on their own. However, if you notice a sudden surge in skin tags it can be a sign of insulin resistance or hormonal imbalance, so a checkup might be wise.

Basal Cell & Squamous Cell Carcinoma Mimics
What should you watch for?
Basal cell carcinomas appear as pearly, translucent bumps that may crust. Squamous cell carcinomas often look like rough, scaly patches that bleed. Both can be confused with warty benign lesions, so any crusting or ulceration warrants a professional look.
