As you know Tarana tablets are nothing but hormonal pills containing estrogen-progesterone
This drug treats irregular period as well as gives protection for ovarian cyst
Now regarding cancer risk; recent studies have shown that using the hormonal pills for a year or more helps protect against uterine cancer
. Long-term Pill use protects against ovarian cancer
. However, the research is mixed about breast cancer
. Breast cancer risk may be slightly increased by the Pill for women with a family history of breast cancer. Women who have a personal history of breast cancer should not take the Pill.
I hope I have clarified your doubt.
