IHC test (ImmunoHistoChemistry): The ImmunoHistoChemistry test finds out if there is too much HER2 protein in the cancer cells. The results of the IHC test can be: 0 (negative), 1+ (also negative), 2+ (borderline), or 3+ (positive â HER2 protein overexpression).
Theme is defined as a main idea or an underlying meaning of a literary work that may be stated directly or indirectly. Major and minor themes are two types of themes that appear in literary works. A major theme is an idea that a writer repeats in his work, making it the most significant idea in a literary work. A minor theme, on the other hand, refers to an idea that appears in a work briefly and gives way to another minor theme.
Analysis of theme involves working the concept, thought, opinion or belief that the author expresses. It is very common (and helpful) to consider theme when analyzing another aspect of literature rather than on its own. The theme of a work is the main message, insight, or observation the writer offers. The importance of theme in literature can be overestimated; the work of fiction is more than just the theme.
