Complementary and Alternative Medicine: What’s the Difference?

It is important to understand the difference between complementary medicine and alternative medicine — the two approaches are often lumped together but are, in fact, distinct.

Complementary medicine refers to healing practices and products that work in conjunction with traditional medicine. For example, a cancer patient receiving chemotherapy may also undergo acupuncture to help manage chemo side effects like nausea and vomiting. Alternative medicine differs in that it is not used as a complement to, but rather as a substitute for traditional therapy. An example would be a cancer patient who forgoes recommended chemotherapy and instead chooses to treat the disease with specific dietary changes.

Would someone who will have surgery and SNB but not rads or chemo if recommended be alternative? Surgery and SNB is conventional?

Imo, surgery and snb is conventional treatment.  

This is one of those definitions that attempts to reflect a hard and fast rule that doesn't match with what people do so is useless.

If someone has only surgery, neither category applies.

If someone has surgery and radiation but refuses Tamoxifen, neither category applies.

And so on.

You don't need these definitions. Just choose what you want to do and remember you don't need a name for it. You don't need permission to do something that falls into a category.
