Study : Body Mass Index (BMI) may affect how well aspirin use protects against colorectal and ovarian cancer

Relevance: Medium-High

Strength of Science: Medium-High

Research Timeline: Post Approval

View Related Clinical Trials

Most relevant for: People concerned about their risk of colorectal or ovarian cancer.

This study looked at the impact of daily aspirin use on the risk for many types of cancers and whether this effect can be modified by risk factors such as obesity, smoking, physical inactivity or a family history of cancer. Daily aspirin use: 

• lowered the risk for colorectal cancer, but this effect was lost as Body Mass Index (BMI) increased.
• lowered the risk of ovarian cancer risk among obese women.
• offered little or no protection against breast, endometrial or advanced prostate cancer.

Most relevant for: Women considering breastfeeding who have inherited BRCA mutations.

Data from a large-scale study suggests that breastfeeding may protect against ovarian cancer in women with inherited mutations in BRCA1 or BRCA2. (1/28/21)

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)

Study : Women who exercise have lower breast cancer risk whether or not they have a family history of breast cancer

Relevance: High

Strength of Science: High

Research Timeline: Post Approval

View Related Clinical Trials

Most relevant for: Young, high risk women

The effect of physical activity on breast cancer risk was looked at  in a study of over 15,000 women. The results suggest that exercise lowers breast cancer risk regardless of family  history of breast cancer or menopausal status.  (12/6/19)

Personal Story : A “flu shot” against breast cancer? Not so fast

Relevance: Medium-Low

Research Timeline: Human Research

Most relevant for: Women diagnosed with Ductal Carcinoma In Situ (DCIS)

There have been multiple reports in the media of a Florida woman who had a "shot" to treat her DCIS with a promising outcome. This XRAY reviews the underlying story about this early breast cancer vaccine trial. (10/25/19)

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)
