The exact cause of skeletal muscle sarcomas is not clear. It initiates when a soft tissue cell undergoes DNA alterations. Subsequently, rhabdomyoblast cells may aggregate to form a tumor mass, which can invade and damage surrounding healthy tissues.
Over time, tumor cells can break away and spread to other parts of the body. When a tumor spreads to other body parts, it is called metastasis.
Symptoms of skeletal muscle sarcomas depend on where the tumor starts in your body.
If the tumor is in the head or neck area, symptoms may include:
- Headaches
- Bleeding in the nose, throat, or ears
- Tearing, bulging, or swelling of the eyes
If the tumor is in the urinary or reproductive system, you may experience the following symptoms:
- Bleeding in the vagina or rectum
- Trouble urinating and blood in the urine
- Trouble with bowel movements
If the skeletal muscle sarcoma is in the arms or legs, symptoms may include:
- Pain and discomfort in the affected area
- Swelling or a lump in the limbs
If the skeletal muscle sarcoma develops in children, symptoms may include:
- Growing lump that is painful
- Crossed eyes or bulging of the eye
- Headaches
- Blood in the urine
- Troubled bowel movements
- Bleeding in the nose, vagina, or rectum
