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.
The THEME of a piece of fiction is its controlling idea or its central insight. It is the unifying generalization about life stated or implied by the story. To derive the theme of a story, we must ask what its central purpose is: what view of life it supports or what insight into life it reveals.
