Symptoms of liposarcoma include swelling and pain near the tumor, abdominal pain, chest pain and bloody stool, constipation or diarrhea, states Drugs.com. Other symptoms include trouble or pain when urinating, weight loss, trouble swallowing or breathing, coughing, or trouble speaking. Symptoms change depending on the location of the tumor.
Some liposarcomas do not cause any symptoms at all, while others are visible under the skin, according to the University of Rochester. Liposarcomas are usually not painful at first, but clear red flags include a new lump or a growing lump that already existed, swelling, numbness or pain at the site of the lump, bloody or tarry stool, bloody vomit and abdominal cramping or pain.
Doctors usually diagnose liposarcoma using a biopsy, the University of Rochester explains. A biopsy requires the removal of some of the tissue in question either through a surgical procedure or with a needle. A pathologist then examines the sample under a microscope to check for cancer cells. If the pathologist identifies the tissue as a liposarcoma, the patient's doctor may order additional tests, such as X-rays, ultrasounds, CT scans or MRIs, to determine treatment options. Chemotherapy, radiation and surgery are methods of treating liposarcomas, states Drugs.com.
