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.

Abstract. Hydrocarbons are compounds that are composed solely of carbon and hydrogen atoms. Saturated, unsaturated, and aromatic hydrocarbons are the three principal classes of naturally occurring hydrocarbons.These classes differ in their chemical and metabolic* activities and relative abundances in organisms and sedimentary deposits.bstract.
