Women and men have approximately equal risk of dying from cancer, which accounts for about a quarter of all deaths, and is the second leading cause of death. However the relative incidence of different cancers varies between women and men. In the United States the three commonest types of cancer of women in 2012 were lung, breast and colorectal cancers. In addition other important cancers in women, in order of importance, are ovarian, uterine (including endometrial and cervical cancers (Gronowski and Schindler, Table III). Similar figures were reported in 2016. While cancer death rates rose rapidly during the twentieth century, the increase was less and later in women due to differences in smoking rates. More recently cancer death rates have started to decline as the use of tobacco becomes less common. Between 1991 and 2012, the death rate in women declined by 19% (less than in men). In the early twentieth century death from uterine (uterine body and cervix) cancers was the leading cause of cancer death in women, who had a higher cancer mortality than men. From the 1930s onwards, uterine cancer deaths declined, primarily due to lower death rates from cervical cancer following the availability of the Papanicolaou (Pap) screening test. This resulted in an overall reduction of cancer deaths in women between the 1940s and 1970s, when rising rates of lung cancer led to an overall increase. By the 1950s the decline in uterine cancer left breast cancer as the leading cause of cancer death till it was overtaken by lung cancer in the 1980s. All three cancers (lung, breast, uterus) are now declining in cancer death rates (Siegel et al. Figure 8), but more women die from lung cancer every year than from breast, ovarian, and uterine cancers combined. Overall about 20% of people found to have lung cancer are never smokers, yet amongst nonsmoking women the risk of developing lung cancer is three times greater than amongst men who never smoked.
Nutrition-sensitive approaches are difficult to link to women's nutritional status (5, 102). This is due to limited measurement of benefits to program beneficiaries, families, households, and communities, limited timeframes to evaluate long-term impact, logistical and political realities that make implementation difficult, and different priorities of different stakeholders in multisectoral programs (102). Many nutrition-sensitive approaches, as will be described, thus focus on more distal measures of impact (e.g., coverage, knowledge) and not more proximal measures of women's nutritional status (e.g., BMI, anemia status, etc.).
