A cyst does not develop into cancer, or raise the risk for cancer.
A cyst in the breast is a round or oval ”bag”, filled with liquid. There may be (one or more) in one or both breasts.
When palpated they give the impression of a soft grape or a small balloon filled with water. Another feature is that their limits are well determined and not vague.
In some cases the impression, upon palpation, is not as described earlier – instead, their consistency seems more solid.
