Women have been invisible in medicine because they have been absent from the subject of biomedical research until the 20th century. Until the last decade of the 20th century, women’s health had been studied and evaluated only in relation to reproductive health and pregnancy and childbirth. It was not until the 1990s that women began to be included in some scientific studies, but without considering the living and working conditions and the key psychosocial burden on health. It is important to emphasize that women are bioaccumulators of toxic substances that affect their health, that of their children and that of their grandchildren.
