A ganglion is a non-cancerous tumor of the soft tissues, most commonly found in the hands and feet, that is typically filled with a thick, clear fluid. It is usually round or oval-shaped and can range in size from several millimeters to many centimeters. These masses are benign, meaning they are not cancerous and generally do not cause harm to the body. Ganglions are localized swellings that can occur when an area of the joint capsule, tendon sheath, or other tissue becomes weakened by injury or overuse. Repetitive motions may also cause ganglia, while their origin remains a mystery in some cases. Regardless of how they arise, these lumps are frequently found near joints and tendons throughout the human body. Ganglion cysts can be troublesome for many, presenting pain or stiffness in the surrounding areas. Compression of nerves may even lead to numbness and tingling sensations across nearby regions. These tumors make motion difficult due to their size and positioning, making them a cause for concern among those affected. Treatment for ganglions is tailored to the individual, depending on factors such as the size and location of the growth and any pain or discomfort caused. Aspirating fluid inside using a needle or syringe can be an option; injection with steroids may also prove helpful, while ultrasound therapy provides another avenue. Severe cases might require surgical excision, yet splints/casts can support milder instances by immobilizing movement in that area.
