text: In 1971, Hamer co-founded the National Women's Political Caucus. She emphasized the power women could hold by acting as a voting majority in the country regardless of race or ethnicity, saying "A white mother is no different from a black mother. The only thing is they haven't had as many problems. But we cry the same tears."
  Later life and death
  While having surgery in 1961 to remove a tumor, 44-year-old Hamer was also given a hysterectomy without consent by a white doctor; this was a frequent occurrence under Mississippi's compulsory sterilization plan to reduce the number of poor blacks in the state. Hamer is credited with coining the phrase "Mississippi appendectomy" as a euphemism for the involuntary or uninformed sterilization of black women, common in the South in the 1960s. She came out of an extended period in hospital for nervous exhaustion in January 1972, and was hospitalized again in January 1974 for a nervous breakdown. By June 1974, Hamer was said to be in extremely poor health. Two years later she was diagnosed with and had surgery for breast cancer.
  Hamer died of complications from hypertension and breast cancer on March 14, 1977, aged 59, at Taborian Hospital, Mound Bayou, Mississippi. She was buried in her hometown of Ruleville, Mississippi. Her tombstone is engraved with one of her famous quotes, "I am sick and tired of being sick and tired."
