That there are such places on Earth where the Sun stays above the horizon for that long and then stays below the horizon for that long is because the Sun is not always above the equator of the Earth, because the rotation axis of the Earth does not make a right angle with the orbit of the Earth around the Sun.
Dear lizme66: Scattered fibroglandular densities means that you have areas of dense breast tissue. This is very common in young women but can remain in some women even after menopause. An asymmetric density means that there is something on the mammogram that does not look quite normal.ear lizme66: Scattered fibroglandular densities means that you have areas of dense breast tissue.

Breast density is a measure used to describe the proportion of the different tissues that make up a womanâs breasts. Breasts are made up of fat and breast tissue (the milk ducts and lobules, which may be called glandular tissue). Connective tissue helps hold everything place.reast and connective tissue are denser than fat and this difference shows up on a mammogram (see images below). 1  High breast density means there is a greater amount of breast and connective tissue compared to fat.
