The staging of cancer and the staging of first to fourth waves of feminism

http://en.wikipedia.org/wiki/Cancer_staging

Stage 0: carcinoma in situ.

Stage I: cancers are localized to one part of the body. Stage I cancer can be surgically removed if small enough.

Stage II: cancers are locally advanced. Stage II cancer can be treated by chemo, radiation, or surgery.

Stage III: cancers are also locally advanced. Whether a cancer is designated as Stage II or Stage III can depend on the specific type of cancer; for example, in Hodgkin's Disease, Stage II indicates affected lymph nodes on only one side of the diaphragm, whereas Stage III indicates affected lymph nodes above and below the diaphragm. The specific criteria for Stages II and III therefore differ according to diagnosis. Stage III can be treated by chemo, radiation, or surgery.

Stage IV: cancers have often metastasized, or spread to other organs or throughout the body. Stage IV cancer can be treated by chemo, radiation, surgery.

http://en.wikipedia.org/wiki/First-wave_feminism

First-wave feminism refers to a period of feminist activity during the 19th and early twentieth century throughout the world, particularly in the United Kingdom, Canada, the Netherlands and the United States. It focused on de jure (officially mandated) inequalities, primarily on gaining women's suffrage (the right to vote).

http://en.wikipedia.org/wiki/Second-wave_feminism

Whereas first-wave feminism focused mainly on suffrage and overturning legal obstacles to legal gender equality (i.e., voting rights, property rights), second-wave feminism broadened the debate to a wide range of issues: sexuality, family, the workplace, reproductive rights, de facto inequalities, and official legal inequalities.

http://en.wikipedia.org/wiki/Third-wave_feminism

Third-wave theory usually incorporates elements of queer theory; anti-racism and women-of-color consciousness; womanism; girl power; post-colonial theory; postmodernism; transnationalism; cyberfeminism; ecofeminism; individualist feminism; new feminist theory, transgender politics, and a rejection of the gender binary. Also considered part of the third wave is sex-positivity, a celebration of sexuality as a positive aspect of life, with broader definitions of what sex means and what oppression and empowerment may imply in the context of sex.
