almanac

ALMANAC is the name of a major breast cancer trial. The acronym stands for "Axillary Lymphatic Mapping Against Nodal Axillary Clearance." This major randomized trial performed in several centres in the UK produced clear evidence that sentinel node biopsy (SNB), used to stage axillary spread of disease, can be used with low failed localization and false negative rates, provided both radioisotope and blue dye are used to locate the sentinel nodes.

An almanac (also spelled almanack and almanach) is an annual publication that includes information such as weather forecasts, farmers' planting dates, tide tables, and tabular information often arranged according to the calendar. Astronomical data and various statistics are found in almanacs, such as the times of the rising and setting of the sun and moon, eclipses, hours of full tide, church festivals, and so on.
