My stepson has been having pain in his thigh for a few months. He just had an MRI done and the Dr. is telling him he has a 4" long tumor and he believes it is malignant. How could he know this without doing an actual biopsy? What are the chances of this being malignant and would might the prognosis be if it is?
How are you doing? Do you have the official result of the MRI?
A biopsy is more definitive in giving a diagnosis of malignancy. There are radiologic features seen in the MRI that can be suggestive of a malignancy. Perhaps this is the basis of your doctor’s impression.
The prognosis depends on the type of tumor your stepson has. It would be best to have a biopsy to be more certain of the type and other histologic features of the tumor.
