Hi, I hope these words to be usefull to you.
Unfortunately ovarian cancer
presents in a late stage by non specific gastrointestinal symptoms like what you mentioned, so your are very clever to suspect such thing.
Since you have a family history of ovarian cancer, I will give you the recommendations for management of women with high risk of ovarian cancer:
1- counseling with a geneticist and genetic testing
for BRCA1 and BRCA2 genes.
2- screening by transvaginal ultrasound
every 6-12 months.
3- taking combined oral contraceptive pills
as long as you don't wish to get pregnant.
4- if the risk is well documented, you can surgically remove your ovaries once you have completed your family.
5- annual mammography
is also recommended after age 30.
At the end I wish you the best of luck and good health.
Dr. Ahmed Bahaa.
