Thanks Phil. Ej here is what I found on it, sounds like this is what it is for me at least.
Lipomas are rarely life-threatening and the common subcutaneous lipomas are not a serious condition. Lipomas growing in internal organs can be more dangerous, for example lipomas in the gastrointestinal tract can cause bleeding, ulceration and painful obstructions (so-called "malignant by location", despite being a benign growth histologically).[23][24] Malignant transformation of lipomas into liposarcomas is very rare and most liposarcomas are not produced from pre-existing benign lesions,[20] although a few cases of malignant transformation have been described for bone and kidney lipomas.[25][26] It is possible these few reported cases were well-differentiated liposarcomas in which the subtle malignant characteristics were missed when the tumour was first examined.[27] Deep lipomas have a greater tendency to recur than superficial lipomas, because complete surgical removal of deep lipomas is not always possible.[27][28]
