Any new lump or mass on a small pet like a hamster should be evaluated by a veterinarian, as it could be an abscess, a cyst, or a tumor (benign or malignant). Hamsters are prone to developing tumors. While not always an emergency requiring an ER visit, it's important to get it checked by a vet soon for diagnosis and treatment options. Early detection can lead to better outcomes. Speak to Dial A Vet via a video consult should you need further guidance.
