It is possible for a surgically removed cyst to grow back. If you have a skin-only cyst, removal is simple and involves numbing your skin followed by a small cut. Your skin surgeon will then squeeze out the protein inside with forceps or suction.
The procedure for removing the cyst will vary depending on its size, location and the condition of your skin. In general, your surgeon will give you an injection of local anesthesia around the area of the cyst and then operate by making a cut in the skin. Then they will insert forceps or other small instruments to grab hold of the sac containing the liquid and remove it through that cut in your skin.
The entire cyst will be removed along with the skin flap and then the remaining tissue will be scraped away. If any part of that lining remains, it can become infected or form another growth at a later time.
If you have been diagnosed with a cyst and your surgeon recommends removing it, there’s a good chance you’ll be able to avoid future growths. Your surgeon may use a local anesthetic or some other painkiller before removing the cyst. Afterward, he or she will likely prescribe antibiotics to prevent infection and watch for signs of healing.
If your cyst is removed and the entire lining has been squeezed out, it’s unlikely that the cyst will grow back. If there are any fragments left, the cyst may recur because the fragments remain to form a germ cell tumor.
