Finding uterine sarcoma while in its early stage (when it is small and has not spread) makes it easier to treat. These are the symptoms that you may notice:
Unusual vaginal bleeding. At first, the bleeding may appear watery with a small amount of blood in it. After a while, the bleeding may appear less watery with more blood in it. After menopause, it is not normal for any amount of vaginal spotting or bleeding to appear, so if you are postmenopausal, you should report this to your doctor as quickly as possible.
Unusual vaginal discharge
Much less common, but possible symptoms include pain or a feeling of fullness in the pelvic area or lower abdomen.
Many of these may be signs of other health problems. Talk with your doctor right away to find out for sure.
