Hi twilight ,
I was told that Ihad a fibro and told to just forget about it which I did ,mine started to grow and on furthur investigations they deceided to remove as it was over 3cm ,(the rule is anything over 3cm should be removed so I believe)I was 50 when mine was discovered (1.2cm )and 52 when removed( then 5cm),I was unlucky when removed they found a nasty hidden inside and ended up having an emergency mx .I think size of lump patients age etc shoud all be taken in to account when deceiding on what action should be taken ,I know if I had a bit more knowledge 5 years back I would have opted for the minor surgery at the time as opposed to the major surgery and the life change I ended up with.
good luck I hope your ends up to be just benign lumps take care lizzy
