Fibroid Symptoms

Should I be concerned about these symptoms?
I have 24 years old and healthy enough, but I had recently entered the room emergency room for severe abdominal pain and was told of the suspected appendicitis. but after an analysis revealed 5 cm mass in my uterus to call OB / GYN, said she thinks of her fibroid. I had also recently lost about 100 pounds without notice during the bulk of 10 months. and months my periods were very irregular. my question is whether this sounds like a fibroid or should be concerned about other issues?
In 100 pounds of weight loss is very serious, this is not normal and if you do something to lose weight, I would be interested. I would like to make an appointment for obstetrics and gynecology to be seen. I've never heard of fibroids cause a person to lose much weight. You want to make sure that is not cancerous.
