Rhabdomyosarcoma
Rhabdomyosarcoma is a rare type of cancer that forms in soft tissue, specifically in skeletal muscle tissue or sometimes in hollow organs such as the bladder or uterus. It most commonly affects children and adolescents.
Characteristics and Behavior
Rhabdomyosarcoma is aggressive and can spread to other parts of the body. It typically presents as a rapidly growing mass, which may cause functional impairment depending on its location.
Symptoms
The signs and symptoms of rhabdomyosarcoma (RMS) vary based on tumor location. Commonly, RMS presents as a persistent and enlarging lump or swelling, potentially painful, often in the arms or legs. In the eye region, it can cause bulging, drooping eyelids, redness, or infection. In the head and neck, symptoms include painless lumps, facial asymmetry, blurred vision, swelling, breathing problems, and possible discharge or bleeding. Abdominal or pelvic RMS may lead to an enlarged abdomen, pain, vomiting, or constipation. RMS in the bladder or prostate can cause blood in the urine and painful urination, while RMS in the reproductive organs may result in painless lumps or vaginal discharge.
Causes
The exact cause of rhabdomyosarcoma is unknown. It involves genetic mutations that lead to abnormal growth of muscle cells.
Risk Factors
Rhabdomyosarcoma is more common in children and adolescents, with no specific known risk factors. Genetic conditions like Li-Fraumeni syndrome (a rare genetic disorder increasing the risk of various cancers due to gene mutations) and neurofibromatosis type 1 (a genetic disorder causing tumors to grow on nerves) can increase risk.
Treatment Options
Treatment for rhabdomyosarcoma often involves a combination of surgery, chemotherapy, and radiation therapy. The treatment plan is tailored to the tumor’s size, location, and stage, and aims to remove the tumor and prevent recurrence.
