Both lipomas and cysts can continue to grow if left untreated. Sometimes, they can cause pain if they press on surrounding tissue or nerves. If a cyst becomes red or inflamed, then it may become infected, which does need treatment. Generally, if the growth is not painful, then it can be left alone. However, many patients find that they dislike the appearance of their growth, which is why many come to Florida Lakes Surgical for cyst or lipoma removal in Sebring.
