Infiltrating ductal carcinoma is by far the most common breast cancer type, and represents about 78% of all cases.
The term ‘infiltrating’ vs. ‘invasive’ is somewhat related to the cancer stage; if the ductal carcinoma is infiltrating the duct wall, then it will usually be termed ‘infiltrating’. However, if the cancer cells are found beyond the duct wall and are starting to ‘invade’ the surrounding tissue, then it will be termed ‘invasive’ ductal carcinoma.
Obviously, an invasive ductal carcinoma suggests a more serious situation and the survival rates will most likely be slightly lower.
The 5 year survival rate for invasive ductal carcinoma was estimated at around 88% (1993 to 2003). However, a more recent Korean study carried out between 1994 and 2010 puts the overall 5 year survival rate at 94.9%.
Tumor size is a really important prognostic factor and can really make a difference. Breast tumors larger than 5cms had a 50 to 60% survival rate over 20 years. Compare this with those who had a tumor of less than 1cm who have a 93 to 98% overall survival rate at 20 years.
