It is possible for a cyst to resolve on its own, depending on the cause and the underlying conditions. However, it is generally best to have a cyst evaluated by a veterinarian to determine the cause and the appropriate treatment. If the cyst is benign (non-cancerous) and not causing any problems, the vet may recommend leaving it alone and monitoring it to see if it goes away on its own. However, if the cyst is causing discomfort or other problems, or if it is cancerous, treatment may be necessary. Treatment options may include draining the cyst, removing it surgically, or prescribing medications to help resolve the cyst.
