At this point the patient is reexamined, a chest x-ray obtained and perhaps a scan of the liver. But for sure the patient needs chemotherapy. This is one case where chemotherapy is given on the basis of a blood test without a tissue diagnosis. If there is B-HCG, and the patient is not pregnant, she must be treated. Sometimes molar tissue will regress spontaneously.
Treatment is usually easy.
Then the patient is followed for a year with B-HCG titers. There is no source of B-HCG other than the trophoblasic cells. After the year is up the patient can become pregnant again. The risk for another molar pregnancy is about doubled. But that is still a small number.
