I just wondered if anyone else has had a similar experience and to ask a bit of advice as have been worrying this week. I am a 50-year-old otherwise healthy female (aside from feeling constantly tired which is probably normal with 3 teenagers in the house!). On Monday I noticed 2 hard lumps on the inside of my left calf. I hadn't noticed them before and I know my body quite well so they have appeared very suddenly. They feel quite deep, but I can feel them even when I lightly move my hand over my leg. When I apply a little pressure, they feel hard and immoveable. I saw my doctor on Wednesday and she said she was not sure  what they were so sent me for an urgent ultrasound which I had today. The person who did the scan (don't know if he was a sonographer or radiologist), said they are fatty lumps, 1 x 2cm and 1 x 1cm, and that he would refer the ultrasound results back to the doctor. The lumps are quite painful when pressed and he seemed to think that was a bit unusual for fatty lumps. I just wondered what I can expect next. I have read a bit about fatty lumps, benign lipomas, which are fairly common, and malignant liposarcomas, which I know are rare, and I wondered if the two types of lumps can be distinguished from each other on an ultrasound or is a biopsy the only sure way to tell? Any thoughts, advice or similar experiences welcomed. I know that the lumps are most likely not cancerous but I worry as my dad was diagnosed with his cancer at my age and died at 56 so just want to make sure that I am armed with all the facts to make sure the follow up is thorough. Thank you!
