I had what I thought was a swelling or lump in 2019 on my left lower body (bottom of ribcage are) it looked bigger than my right side so I went to the doctors. Ultrasound was done that said it was a lipoma and I think it was about 4cm I had another ultrasound done in 2020 as I felt it may have got bigger but when I had the ultrasound done they couldn’t see it and said it was a thickening of the sebaceous fat. Because I had two ultrasounds it was left, fast forward 2024 now and I felt it again thought it might have felt bigger scheduled a appointment with Gp and he felt it and said yes it feels bigger from the ultrasound I had a few years ago he asked was it painful I said no it’s not painful but it’s bothersome now I can feel it. I asked why did the second ultrasound not pick it up and only thickening fat but not the lipoma that was picked up on the first ultrasound, the doctor said they don’t disappear but can swell and go down. He said he can feel it’s ‘swelling’ ‘

The doctor said ‘no obvious red flags but going to send me ultrasound to differentiate’ (whatever that means?) and to rule out anything serious. The ultrasound was issued as ‘routine’ 

im very worried and just want to chat to others and what can the above mean? Obviously I’m worried if it’s gone bigger than the 4cm ultrasound from 2019 which the doctor said feeling it - it had gone bigger- what will they do after ultrasound does that mean it’s more likely to be cancerous or something if it’s growing?
