One of the important aspects of REST (or at least HTTP) is the concept that some operations (verbs) are idempotent. As Gregor Roth said several years ago: The PUT method is idempotent. An idempotent method means that the result of a successful performed request is independent of the number of times it is executed. Idempotency is also something discussed in the SOA Design Patterns.
Invasive and infiltrative are synonyms. IDC means invasive ductal carcinoma or infiltrative ductal carcinoma.. There is no difference between the terms. In either case, it means the cancerous cells have been able to spread outside the ducts where they originated, and move into the surrounding breast tissue. That's definitely worse than DCIS. Even if the cells of a tumor have become invasive, it doesn't necessarily mean they have spread to tissues beyond the breast (i.e., lymph nodes or other tissues).
