In the 2014 case Burwell v. Hobby Lobby, the US Supreme Court ruled that the contraceptive mandate promulgated under the Patient Protection and Affordable Care Act violated privately held, for-profit corporations’ right to religious freedom. The contraception mandate, issued in 2012 by the US Department of Health and Human Services, required that employer-provided health insurance plans offer their beneficiaries certain contraceptive methods free of charge. In a five to four decision, the US Supreme Court maintained that the mandate, in cases of privately held, for-profit organizations like Hobby Lobby Inc., violated the Religious Freedom Restoration Act of 1993. Although the Court did not decide on the constitutionality of the mandate, their ruling enabled privately held, for-profit corporations that objected to the contraceptive mandate on religious grounds to be exempt from it.

In 1894, William Stewart Halsted published The Results of Operations for the Cure of Cancer of the Breast Performed at the Johns Hopkins Hospital from June, 1889, to January, 1894, in the medical journal Annals of Surgery. In the article, Halsted describes the results from fifty of his operations on women with breast cancer, performed at Johns Hopkins Hospital in Baltimore, Maryland. Those operations involved a surgical procedure Halsted called radical mastectomy, which consists in removing all of the patient’s breast tissue, chest muscle, and underarm lymph nodes. Halsted’s surgery effectively cured breast cancer in a time period when no other effective treatment options were available. The radical mastectomy remained the standard of care from the 1890s to the 1970s as a means of treating a type of reproductive cancer common to women.

During the twentieth century, Austin Bradford Hill researched diseases and their causes in England and developed the Bradford Hill criteria, which comprise the minimal requirements that must be met for a causal relationship to be established between a factor and a disease. Hill also suggested that researchers should randomize clinical trials to evaluate the effects of a drug or treatment by monitoring large groups of people. In addition, Hill advocated for case-control studies, in which researchers compare a group of people with a medical condition to a group without that condition to investigate the condition's possible causes. Hill's own work with clinical trials and case-control studies helped him prove that smoking caused lung cancer. The Bradford Hill criteria have also been used to establish causal links between factors and cancer, including reproductive cancers such as human papillomavirus that causes cervical cancer.

Dorothy Andersen studied cystic fibrosis in the United States during the early 1900s. In 1935, Andersen discovered lesions in the pancreas of an infant during an autopsy, which led her to classify a condition she named cystic fibrosis of the pancreas. In 1938, Andersen became the first to thoroughly describe symptoms of the medical condition cystic fibrosis. Commonly mistaken for celiac disease prior to the 1900s, Andersen defined cystic fibrosis as the build-up of pancreatic fluid in the body caused by the blockage of pancreatic ducts, and she determined that the two conditions were symptomatically different. Andersen developed an early method for
diagnosing cystic fibrosis. By conceptualizing cystic fibrosis and
defining its symptoms, Andersen laid the foundation for treatments that
enabled infants diagnosed with the disease to survive into adulthood.

Better babies contests were competitions held in state fairs throughout the US during the early twentieth century in which babies between the ages of 6 and 48 months were judged for their health. In 1908, social activist Mary de Garmo established and held the first better babies contest at the Louisiana State Fair in Shreveport, Louisiana. The contests, mirroring theories established in the US’s eugenics movement of the twentieth century, aimed to establish standards for judging infant health. Nurses and physicians judged infants participating in the contest on mental health, physical health, and physical appearance. In 1913, the Woman’s Home Companion (WHC) magazine cosponsored de Garmo’s better babies contests and introduced the competition to state fairs throughout the US. Better babies contests helped promote routine health assessments of children by medical professionals.

Percivall Pott was a physician in England during the eighteenth century who identified soot as the cause of chimney sweeps' scrotal cancer, later called testicular cancer. In the 1770s, Pott observed that scrotal cancer commonly afflicted chimney sweeps, the young boys sent up into chimneys to clean away the soot left over from fires, and he hypothesized that the soot inside chimneys might cause that type of cancer. Pott was one of the first doctors to identify some environmental factor as causing cancer. Pott's research helped chimney sweeps to prevent scrotal cancer by using protective clothing, and it also allowed for future research on environmental causes of cancers.

On 30 June 1980, in a five to four decision, the US Supreme Court ruled in the Case Harris v. McRae that the Hyde Amendment of 1976 did not violate the US Constitution. The Hyde Amendment banned the use of federal funding to pay for any abortion services. The US Supreme Court's decision in Harris v. McRae overturned the decision of McRae v. Califano (1980), in which the US District Court for the Eastern District of New York had ruled that the funding restrictions established by the Hyde Amendment violated the US Constitution. After the US Supreme Court's ruling in Harris v. McRae, the Hyde Amendment continued to prohibit federal Medicaid funding for abortion services, limiting the funds available for low-income women seeking abortions.

In the 2012 case Texas Medical Providers Performing Abortion Services v. David Lakey, a US appeals court ruled as constitutional a Texas law that required abortion providers in the state to show women receiving abortions the ultrasound images of their fetuses. The law also required providers to describe the sounds of the fetuses' nascent hearts. In doing so, the court set precedent that ultrasound readings are necessary medical information for pregnant women seeking abortions, increasing the wait-period for women seeking abortions. The decision fueled debates in the early twenty-first century US abouts women's rights to abortions.

In 1976, the US Congress passed the Hyde Amendment, which banned the use of federal funding to pay for abortions through Medicaid. In 1976, Illinois Congressman Henry J. Hyde proposed the amendment to the Departments of Labor and Health, Education, and Welfare, Appropriation Act of 1977. In 1980, the US Supreme Court in Harris v. McRae (1980) upheld the constitutionality of the Hyde Amendment. Included annually in every Congressional appropriation act after the one passed in 1976, amended versions of the Hyde Amendment have restricted federal funding of abortion services for women participating in Medicaid.
