Hypothesis
Is there a significant correlation between serum oestradiol levels and various breast diseases?
Conclusion
Women with breast cancer have higher levels of free oestradiol percentage compared to both normal women and women with benign breast disease.
Supporting Evidence
- 67% of breast cancer patients had free E2% values greater than the mean of 1.70.
- The percentage of free oestradiol was highest in women with breast cancer and lowest in the control group.
- The study is one of the largest to analyze serum oestradiol profiles in women with benign breast disease.
Takeaway
This study found that women with breast cancer have more of a certain hormone in their blood compared to women without breast disease, which might help in diagnosing breast cancer earlier.
Methodology
Blood samples were taken from 300 women categorized into control, benign breast disease, and breast cancer groups to analyze serum oestradiol profiles.
Limitations
The study did not establish a correlation between oestrogen receptor levels and free oestradiol percentages.
Participant Demographics
The study included 300 women: 143 in the control group, 117 with benign breast disease, and 40 with breast cancer, with a mix of premenopausal and post-menopausal participants.
