Sarcoids are the most common skin tumour in horses and require careful treatment decisions balancing effectiveness, recurrence risk, and horse welfare.
Sarcoid management is a welfare challenge because treatment decisions carry significant recurrence risk. Ineffective treatment may stimulate more aggressive regrowth than leaving the sarcoid untreated. Horses with sarcoids in sensitive locations experience chronic irritation, pain from harness contact, and in severe cases, functional compromise of vision or limb use. Choosing the right treatment requires specialist equine dermatology or oncology expertise. The financial cost of effective treatment creates welfare disparities where horses in resource-limited ownership receive inadequate or counterproductive interventions. Long-term monitoring after treatment is essential to detect recurrence before regrowth becomes unmanageable.
