Hello, nice to know your good concerns for your friend. An ultrasound
picture can give clues as to the nature of the mass whether benign or malignant.
The age of the person, coexisting systemic symptoms like loss of appetite and weight, lymphnode enlargement, family history of cancer and all such details an give us a probable diagnosis as to the nature of the finromyoma. Nevertheless,the biopsy
only will give an exact picture. So if the ultrasound says it is just a fibromyoma, it is mostly in favour of a benign condition. But only biopsy is confirmatory. So relax till then. Hope for the better. Take care!
