I am concerned about the way Ms. Weeks has misconstrued ABUS as an 'alternative' to mammogram. ABUS is approved by Health Canada for screening purposes, as an addition to mammography. Ms.Weeks neglected to write about why ABUS is beneficial as a supplementary screening tool. For women with dense breast tissue, tumours are sometimes hidden behind dense tissue because both  appear white on a mammogram.  40% of women over age 40- 3 million women in Canada- have dense breasts. ABUS finds small, invasive, node negative cancers. Evidence shows ABUS detects an additional 3.6 cancers per 1000 women screened after mammography (Berg, 2016). ABUS, in addition, to mammography can significantly improve cancer detection for women with dense breasts.  In fact, the Alberta health ministry covers the cost of ABUS for women with the highest level of breast density. By ignoring how ABUS is a beneficial supplementary screen for women with dense breasts, Ms. Weeks failed to provide a complete picture.
