Somebody had a multiple cyst in breast that was in 2015. After that it was disappear. Does it happen like that? The size like 50*32 mm can disappear? Now it again feel that there are cyst but this time it is little more big, hard and painful. Can it be cancerous? In 2015 she consulted 2 to 3 doctors they told that its very big in size so it will not disappear and you have go with plan surgery. This time again my question stands same. Does she needs to operate?
