Definitely: There are lots of different subtypes of breast cancer. All have different prognoses and different recommended treatments.

Yes: There are several types of breast cancer, and some are worse than others, for instance a sarcomotoid breast cancer is very aggressive nd resistant to treatment. Even within ductal carcinomas (the most common type of breast cancer) we now recognize three separte types, luminal (phenobarbital) a, luminal (phenobarbital) b, and basal, with basal being the most aggressive.

Many: We're just starting to understand the different types. General categories are er+, er/pr/her2+, er-/her2+, and er/pr/her2-. Her2+ tend to be more aggressive but can be counteracted w/herceptin. Triple neg are also more aggressive but some of these are very chemosensitive. Genomic analysis/microarrays allows further subdividing. The environment of the tumor in the body is also likely critical.

NCI: National cancer institute website (www.Cancer.Gov) has info by cancer type. There are other reputable websites as well. Do not get your info from sites that sound like like "uncle joe's cancer network" not all you read in the web is true.

A large number: Wikipedia is pretty good on this. It's a major research subject nowadays as well as a big part of a pathologist's job. http://en.wikipedia.org/wiki/breast_cancer_classification.
