Soft Tissue Tumor

Soft tissue tumors are abnormal growths that start in the body's connective tissues, including fat, muscle, blood vessels, and nerves. Most of these growths are benign (not cancer), but some can be malignant (cancer, known as sarcoma).

What Are Soft Tissue Tumors?

Abnormal lumps or masses growing in tissues that connect, support, or surround other body structures.

Common Types: Lipomas (fat tumors), hemangiomas (blood vessel growths), and nerve sheath tumors.
Benign vs. Malignant: Non-cancerous tumors are far more common, usually small (under 5 cm), and grow slowly just under the skin.

Signs and Symptoms

Painless Lump

A soft or firm mass under the skin that you can often move with your fingers.

Growing Size

A lump that gets bigger over time, especially if it grows larger than 5 cm or feels deep under the muscle.

Aches or Pressure

Pain, numbness, or trouble moving a limb if the mass presses against a nerve or muscle.

Diagnosis and Treatment

Imaging Tests

Doctors use ultrasounds, MRIs, or CT scans to look at the size and depth of the mass.
Biopsy

A small tissue sample is taken and checked under a microscope to see if it is benign or a sarcoma.
Options

Benign lumps may only need regular watching or a simple removal surgery. Malignant tumors require specialized cancer care, including surgery, radiation, or chemotherapy
