Thanks for writing to us.
is malignant tumour that arises in fat cells of deep soft tissue
. Since it is rapidly growing & painful is a matter of concern .
Only way to prove whether it is benign or malignant is to get biopsy
done that will help to differentiate what is the cause. Dont worry , biopsy is a minor procedure where a small piece of tissue is removed & cells in the tissue are observed under microscope.
Liposarcoma is treated with surgery & radiation
& has less chance of recurrence.
