Life Expectancy. The life expectancy of lung cancer patients depends on the cancer stage as well as how early it is detected. The five year survival rate for those with stage 1 lung cancer is 60-80%, although more recent studies show that early detection increases this rate to 90% of more.The survival rate for stage 2 is 40-50%.For stage 3 lung cancer, the life expectancy significantly varies.Variables include type of cancer, age, sex, other medical conditions and responsiveness to treatment. The average life expectancy of someone with stage 3 non small cell cancer, in which 50% have lived, ranges from 13-15 months.The percentage of patients who survive 5 years after diagnosis is 23% for stage 3A and 10%.he five year survival rate for those with stage 1 lung cancer is 60-80%, although more recent studies show that early detection increases this rate to 90% of more. The survival rate for stage 2 is 40-50%. For stage 3 lung cancer, the life expectancy significantly varies.
A chemical compound (or just compound if used in the context of chemistry) is an entity consisting of two or more atoms, at least two from different elements, which associate via chemical bonds.
In the case of carbon dioxide, different elements are combining, so the molecule is called a compound. We usually deal with chemical compounds, since there are so many possible combinations. Thus, a compound is a molecule that is made up of at least two different elements.Chemical formulas Chemical formulas (or more correctly: formulae) are designations of molecules and compounds in shorthand notation, similar to that used in Algebra. chemical formula is writing the elements of a compound, using their abbreviations. Number of atoms in a molecule If there is more than one atom of a type in the molecule, the formula shows it by a small number after the symbol.
