Study : Insulin resistance linked to differences in breast cancer survival between Black and White women

Relevance: Medium-High

Strength of Science: Medium

Research Timeline: Human Research

View Related Clinical Trials

Most relevant for: Black women

Black women are more likely to die from breast cancer compared to White women. More Black women have a condition called insulin resistance than White women.  This study found that insulin resistance might be one of the reasons that Black women are more likely than White women to die from breast cancer. Additional research is needed to see if lowering insulin levels will improve breast cancer survival in Black women. (07/30/20)

Study : What is the risk for a new breast cancer diagnosis in the other breast for women with a BRCA1, BRCA2 or TP53 mutation?

Relevance: High

Strength of Science: Medium-High

Research Timeline: Post Approval

Most relevant for: Women diagnosed with breast cancer who have a mutation in BRCA1, BRCA2 or TP53

For women who have been diagnosed with breast cancer, knowing their risk of breast cancer in the other (contralateral) breast can help them make decisions about surgery and screening. This study shows that women with an inherited mutation in BRCA1, BRCA2 or TP53 have an increased risk for contralateral breast cancer. This risk is highest in women with a TP53 mutation. (6/6/20)

Study : Racial and ethnic differences in genetic testing among young breast cancer survivors

Relevance: High

Strength of Science: Medium-High

View Related Clinical Trials

Most relevant for: Women diagnosed with breast cancer at age 50 or younger

Genetic testing is recommended for most women who are diagnosed with breast cancer at age 50 or younger.  In this study of young women with breast cancer, while the rates of genetic testing  did not differ, the rates of women testing positive for an inherited mutation associated with breast cancer did vary between racial and ethnic groups.

Study : Cancer risk associated with inherited mutations in Lynch syndrome genes

Relevance: Medium-High

Strength of Science: Medium-High

Research Timeline: Human Research

View Related Clinical Trials

Most relevant for: People with Lynch syndrome mutations

Lynch syndrome is the most common inherited cause of cancer affecting about 1 in 300 people. People with Lynch syndrome have an increased risk of colorectal endometrial and other cancers. A large study followed people with mutations in the Lynch syndrome genes MLH1, MSH2, MSH6 and PMS2 to determine the risk of other types of cancer. (2/21/20)

Study : Do hair dyes or straighteners increase breast cancer risk?

Relevance: Medium-High

Strength of Science: Medium-Low

Most relevant for: Young women who use hair dye or straighteners

Many women use products to color or straighten their hair. A large U.S. study linked the use of permanent hair dye and straighteners to increased breast cancer risk, particularly among black women. This XRAY reviews the limitations of this study and highlights the need for additional research before accepting these conclusions. (1/29/20)

Update : Genetic causes of hereditary pancreatic cancer: BRCA and beyond

Relevance: High

Research Timeline: Post Approval

View Related Clinical Trials

Most relevant for: People diagnosed with pancreatic cancer

An update on hereditary pancreatic cancer presented at the annual American Society of Clinical Oncology meeting covered genes and lifetime risk. The update emphasized that all pancreatic cancer patients should be offered genetic counseling and testing. Genetic test results may impact treatment, screening for other cancers and risk to family members. (11/26/19)

Study : Does eating meat affect breast cancer risk?

Relevance: Medium-High

Strength of Science: Medium-High

View Related Clinical Trials

Most relevant for: Women with a family history of breast cancer

Eating meat has been suggested to increase breast cancer risk. The recent Sister Study looked at meat type, cooking methods and breast cancer risk in a study of 42,012 women.  (9/10/19)

Study : MRI or mammograms for detecting breast cancer in families with unknown genetic mutations?

Relevance: High

Strength of Science: Medium-High

Research Timeline: Post Approval

View Related Clinical Trials

Most relevant for: People with a personal or family history of cancer where no mutation has been found

MRI and mammograms are used together to detect breast cancer in high-risk women who test positive for a BRCA or other gene mutation that increases the risk for breast cancer. For women with a family history of breast cancer but no known genetic mutation, increased screening is recommended. But what method is best? A recent clinical trial in the Netherlands compared MRI and mammography for this population. (8/15/19)

Study : Diagnosis and treatment delays in young women with breast cancer

Relevance: Medium-High

Strength of Science: Medium-High

Most relevant for: Young women who find a breast lump and young women newly-diagnosed with breast cancer

Young women are more likely to have delays in a breast cancer diagnosis and treatment.  Factors that affect these delays include pregnancy, breastfeeding, financial concerns and having a family history of breast or ovarian cancer. (8/5/19)

Guideline : FDA asks Allergan to recall certain textured breast implants

Relevance: High

Research Timeline: Post Approval

View Related Clinical Trials

Most relevant for: Women with, or considering breast reconstruction with implants

On July 25, 2019, the Food and Drug Administration requested that breast implant manufacturer Allergan recall its BIOCELL textured implants and expanders due to an association with a rare type of lymphoma called Breast Implant Associated Anaplastic Large Cell Lymphoma or BIA-ALCL. The FDA does not recommend removing implants for people who do not have disease symptoms. This XRAYS review updates information about this FDA recall. (7/29/19)
