Most cysts are benign and have very little chance of becoming cancerous. However, if a cyst gradually increases in size and causes discomfort, it needs to be treated promptly to avoid affecting the physiological functions of the body. If a cyst in the body does not cause any health effects, it does not need any treatment and can be followed up and observed regularly. However, if the cysts cause swelling, pain and other discomforts, or if they grow in special places, such as within the thyroid gland, liver, kidney and other parts of the body, it is necessary to choose a reasonable treatment in time according to the size, quantity and nature of the cysts, which usually will not affect the life span of the patients. Therefore, patients with cysts should usually have regular follow-up and observation, and if necessary, they can go to the medical oncology department of regular hospitals to get a clear diagnosis and then treat them symptomatically.
