Abstract:
The DENSE trial has demonstrated that offering an MRI scan to women with very dense glandular breast tissue and normal results on screening mammography reduces the number of interval cancers by 50%. In the women who agreed to undergo an MRI (59%), this reduction was 80% (from 5 per 1000 to 1 per 1000 participants). DENSE will continue in order to answer the only question that is relevant to patients: does additional MRI lead to less invasive treatment and, above all, to a decrease in mortality? Even in the event where additional MRI screening would lead to a decrease in mortality, we still need to have an open discussion on whether investing in additional MRI screening for women with very dense glandular tissue is the most effective way to improve the health of the Dutch female population. Thanks to the great effort of the DENSE research team, such a discussion can be pursued thoroughly, based on facts.

Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...

Dense Regular Connective Tissue
In dense regular connective tissue, fibers are arranged parallel to each other, enhancing its tensile strength and resistance to stretching in the direction of the fiber orientations. Ligaments and tendons are made of dense regular...
