Study : Genetic testing among people with cancer can find mutations that may affect treatment and prevention

Relevance: High

Strength of Science: High

Research Timeline: Post Approval

Most relevant for: People diagnosed with cancer who have not yet had genetic testing

Despite national guidelines recommending genetic testing, less than 10 percent of eligible patients had genetic testing within two years after their cancer diagnosis. Among those who had testing, 10-30 percent had an inherited mutation that could affect their medical care. (Posted 3/15/2024)

Study : Estrogen without progesterone for hormone replacement may lower breast cancer risk

Relevance: Medium-High

Most relevant for: Postmenopausal people on hormone replacement therapy

Women with average breast cancer risk who took estrogen without progesterone after menopause had lower rates of breast cancer than those who did not take any hormone replacement. This finding comes from studies looking at the safety of the use of estrogen alone as hormone replacement therapy. (Posted 2/13/24)

Study : Weight may affect breast cancer risk in women with an inherited BRCA mutation

Relevance: Medium

Strength of Science: Medium

Research Timeline: Animal Studies

View Related Clinical Trials

Most relevant for: People with an inherited mutation in BRCA1 or BRCA2 concerned about their breast cancer risk

A study that looked at normal breast cells from women with an inherited BRCA mutation found more DNA damage among women who were overweight (based on a measurement known as body mass index) than those who were not overweight. The results suggest that maintaining a lower weight may reduce breast cancer among this high-risk population. (Posted 3/30/23)
