Abdominal tumors are abnormal growths that can develop in the abdomen, which is the area of the body between the chest and pelvis. These tumors can be benign (non-cancerous) or malignant (cancerous) and may arise from various tissues, including organs like the stomach, liver, or intestines. Symptoms can include pain, swelling, or changes in digestion. Diagnosis typically involves imaging tests such as CT scans or MRIs, and sometimes a biopsy is performed to determine the nature of the tumor. Treatment options vary based on the type and stage of the tumor and may include surgery, chemotherapy, or radiation therapy.
