Sometimes, cancer cells release substances into the bloodstream that cause symptoms that are not usually linked to cancer. For example, some cancers of the pancreas can release substances that cause blood clots in veins of the legs. Some lung cancers make hormone-like substances that raise blood calcium levels.
Main article: Meter (poetry) Prosody is the study of the meter, rhythm, and intonation of a poem. Rhythm and meter are different, although closely related. Meter is the definitive pattern established for a verse (such as iambic pentameter), while rhythm is the actual sound that results from a line of poetry.
But when you dive into the sounds, the reader can often see poetry rooted in a rhythmic, repeatable patterns; song-like in its nature. Meter (or rhythm) gives poem structure, and one such metrical line is known as the Iambic pentameter. It is a very common convention that is used in traditional English poetry verses.
