If you do not want to read about survival rates for small cell lung cancer, stop reading here and skip to the next section. The 5-year survival rate refers to the percentage of patients who live at least 5 years after their cancer is diagnosed.Of course, many of these people live longer than 5 years.To get 5-year survival rates, doctors look at people who were treated at least 5 years ago. Improvements in treatment since then may result in a more favorable outlook for people now being diagnosed with small cell lung cancer (SCLC).f course, many of these people live longer than 5 years.

Chemical compound. A chemical compound is a chemical substance consisting of two or more different chemically bonded chemical elements, with a fixed ratio determining the composition. The ratio of each element is usually expressed by chemical formula. For example, water (H2O) is a compound consisting of two hydrogen atoms bonded to an oxygen atom. The atoms within a compound can be held together by a variety of interactions, ranging from covalent bonds to electrostatic forces in ionic bonds.
