There are many types of benign (noncancerous) soft tissue tumors, some
of which are quite common, such as lipoma. Most benign soft tissue
tumors do not grow beyond the tissue in which they formed or spread to
other sites. Some, however, can be locally aggressive or can come back
after they have been surgically removed.
A lump or swelling in the area of a benign soft tissue tumor is the most
common symptom. The lump usually is painless and may go unnoticed. If a
benign tumor continues to grow, it may become large enough to press on
nerves or other structures, causing pain or other symptoms.
Lumps that are small, right under the skin, not growing, and not causing
symptoms usually can be watched. However, a lump that is large, deep, growing,
or causing symptoms or other problems needs to be evaluated to be sure the lump
is not suspicious for cancer. Most of these lumps will be benign tumors that can
be treated with appropriate surgical resection after a well-planned biopsy and
careful tissue diagnosis to verify that they are in fact benign.
