A new breast cancer model has been developed and validated for breast cancer risk prediction, specifically for Black women in the United States. This is in contrast to prior models, which were developed in White women, and used in Black women (which UNDERPREDICTED risks). This is a notable advance as we strive towards health equity …

Of note, MLH1 and MSH2 carriers have the highest risk of colorectal cancer, generally in the range of 43%-52% by age 70. A recent …

A worldwide study suggests that risks for cancers for the various Lynch syndrome genes have some differences. The risk of colorectal cancer for those with a mutation in the MLH1, MSH2 and MSH6 genes is higher than what is seen for carriers of a PMS2 mutation. Additionally, men with MSH2 gene mutations have a higher …
