Invasive Ductal Carcinoma (IDC). Invasive ductal carcinoma (IDC), also known as infiltrating ductal carcinoma, is cancer that began growing in the duct and has invaded the fatty tissue of the breast outside of the duct. IDC is the most common form of breast cancer, representing 80 percent of all breast cancer diagnoses.nvasive ductal carcinoma (IDC), also known as infiltrating ductal carcinoma, is cancer that began growing in the duct and has invaded the fatty tissue of the breast outside of the duct.

Unsaturated hydrocarbon : a hydrocarbon that contains one or more carbon-carbon. double bonds, triple bonds, or benzene rings. Alkanes : They are saturated hydrocarbons (they have only carbon-carbon single bonds). The. molecular formula of this group is C nH2n+2 (n is the number of carbon atoms). Naming the unbranched alkanes : Chemists have adopted a set of rules established by the. International Union of Pure and Applied Chemistry (IUPAC).
