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.

Definition - What does Unsaturated Hydrocarbon mean? Unsaturated Hydrocarbon is a hydrocarbon that has double or triple covalent bonds between adjoining carbon atoms. These bonds make unsaturated hydrocarbons more reactive than the saturated hydrocarbons. They have fewer hydrogen atoms bonded to carbon atoms as compared to saturated hydrocarbons. Hydrocarbons having at least one triple bond are known as alkynes and those having, at least, one double bond are known as alkenes.
