Lipomas are another common "lump" that we are asked to evaluate. These are almost always benign, fatty tumors that are usually straight forward to treat by excision. However, cancers that have a similar appearance such as liposarcoma or a different type of soft tissue cancer can be present. If you have experienced a subcutaneous lump for years and it has remained unchanged, it is most likely benign. But, if you do notice growth and/or increasing discomfort due to pressure the growth is exerting on the surrounding tissue, consider excision soon. These masses are easier to excise when they are small.
