The likelihood of death within twenty years of a diagnosis for DCIS (ductal carcinoma in situ, a type of breast cancer) is only 3.3%. Does this mean that every individual diagnosed with DCIS has a 3.3% chance of death within twenty years from the disease?
It means that within twenty years 33 out of 1000 (0r 3,3 out of 100 better understandable with 33 persons instead of 3,3) has the chance to die because of the disease.
