How commonly are lumps misdiagnosed as lipomas?

I can relate. A few months ago, I too had an abdominal mass. I saw my Oncologist and he ordered an ultrasound then told me it was a lipoma. Then he said sebaceous cysts. He couldn't feel a core, which means it would have been the cysts, so he determined it was a lipoma. Yeah, I know that feeling, but I trust my Oncologist without question. Maybe I'm being naive but this man saved my life. I don't believe after proper testing, they make mistakes. The evidence is in the ultrasounds, or MRI. It's scary, but trust your doctor and as always, if it makes you wonder still, then get another opinion. I believe in second opinions. That's how I found my Oncologist. Good luck. Lipomas are not cancer.
