What Are Benign Growths & Lesions?
Benign growths and lesions are non-cancerous skin changes that can appear anywhere on the body. While they are generally harmless, some can cause discomfort, affect appearance, or become irritated if rubbed or injured. Identifying them correctly is important to rule out more serious conditions and choose the right management.
Medical Definition
A benign skin growth or lesion is an abnormal proliferation of skin cells, fat, or other tissues that does not invade surrounding tissues or spread to other parts of the body.
- Common types include moles (naevi), skin tags, seborrhoeic keratoses, lipomas, and dermatofibromas.
- They can vary in colour, texture, and size, from flat spots to raised nodules.
- Causes include genetic predisposition, sun exposure, friction, ageing, and hormonal changes.
- Though benign, some lesions can mimic skin cancer, requiring professional assessment.
- Treatment may be elective (for cosmetic reasons) or necessary if the lesion causes irritation, bleeding, or a rapid change in appearance.
