A sonogram, two days ago, to monitor health of kidney after first kidney stone and possible related mild/moderate issues revealed another small stone and surprise -- a 4 cm cyst on my right ovary which is giving off mild twinges. I also experience intermitten nausea with no desire to eat. I still have my cycle although irregular lately with intermitten bleeding between (thought this might be the approach of menopause, but apparently that may not be the case). I also have been having heavy cycle every other month for about 1 year which includes a great deal of pain in abdomen and lower back that sometimes radiates down to thigh. Family history is (in a nutshell) mother with metastatic colon cancer and sister who carries the BRCA 1 gene discovered after her breast cancer diagnosis. Other extended family members with various cancers as well. My concern is do I wait, as advised by physician, 4 weeks for another cycle to have a vaginal ultrasound to see of the cyst resolves itself? Am I over-reacting? To appease me my physician ordered a CA 125 -- I know this is not a diagnostic test and there are false positives and false negatives, etc.
