Hi @Laalaa ..... welcome to the blog. So they are just keeping an eye on it at this point in time? No mention of a biopsy? You could ask if a biopsy would be recommended?
If you go to the top of the 'DISCUSSIONS' page, there is a 'search' area .... if you type in 'Hypoechoic' - it will bring up any threads where that word has been mentioned before - and there are a few!! ;)
Mine wasn't 'lobulated hypoechoic lesion' - mine was a 'Hypoechoic fat necrosis' .... and I had a biopsy done on it 'to be sure' and it came back as 'fine'. It has basically shown up every year since my surgery in 2018 .... I just had my yearly scans 10 days ago & so far, it is the first time it doesn't appear to have been mentioned this time! YAY!
Take care, xx
