Skin Growths, Moles and Tumours
Skin growths cover a wide range of new or changing spots, lumps and bumps. Most are benign (harmless), some are premalignant (could become cancerous if left untreated), and a few are malignant (skin cancers).

Why they occur
Many benign growths are related to age and family history. Premalignant and cancerous lesions may be associated with factors such as cumulative sun exposure, reduced immune function, previous radiation exposure, or chronic non-healing wounds.
Signs That Require Medical Attention
A mole or spot that changes in size, shape or colour, or has an irregular border or several colours.
A growth that bleeds, crusts, itches or is painful.
A sore that does not heal within a few weeks.
A new growth that appears and grows quickly.
Any lesion showing these features should be evaluated promptly by a dermatologist. Growths should not be removed at home or treated with acids, burning agents, or unverified remedies.
Evaluation
Each growth is assessed through clinical examination and, where indicated, dermoscopy to examine its features more closely. A skin biopsy may be necessary to establish the diagnosis, particularly when a lesion appears suspicious. Tissue samples are sent for laboratory examination to determine the nature of the growth.
Treatment
Many harmless growths can simply be observed. Benign growths such as moles and skin tags can be removed when they are cosmetically bothersome or cause problems such as repeated friction, bleeding or irritation. Removal may involve electrocautery-based techniques or a minor surgical procedure, depending on the type, size and location of the lesion.
For lesions that are premalignant or cancerous, a confirmed diagnosis comes first. Treatment is then planned according to the type and extent of the lesion, and may include surgical excision, systemic medical treatments, with referral to other specialists where needed.
Key Takeaway
Any lesion showing these features should be evaluated promptly by a dermatologist.
