Understanding Lab Tests for Estrogen-dependent cancers
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Estrogen-dependent cancers, including certain types of breast, endometrial, and ovarian cancers, are malignancies whose growth is stimulated by estrogen hormones. These cancers are typically diagnosed through imaging studies, biopsies, and tissue analysis. While there is no single blood test to diagnose estrogen-dependent cancers, hormonal testing plays a crucial role in risk assessment and monitoring.
Recommended Test
Estradiol, Ultrasensitive, LC/MS/MS
This highly sensitive test measures estradiol levels in the blood. Estradiol is the most potent form of estrogen and can stimulate the growth of estrogen receptor-positive cancers. Elevated estradiol levels may indicate an increased risk for developing these hormone-dependent cancers, making this test valuable for risk stratification and monitoring.

Why Estrogen Testing is Important
Blood tests measuring estrogen levels are fundamental for assessing cancer risk, particularly in individuals with a family history or other risk factors. Elevated estrogen levels, especially estradiol, can indicate increased risk for hormone-sensitive cancers. This testing is also valuable for monitoring hormone levels during treatment and evaluating the effectiveness of hormone-blocking therapies.
Understanding Your Results
Estradiol levels can vary based on age, menstrual cycle phase, menopause status, and other factors. While elevated levels may suggest increased cancer risk, many factors influence estrogen production. Results should always be interpreted by a healthcare provider who can consider your individual medical history and risk factors.
