Low-fat dairy products are excellent sources of calcium. Other good sources of calcium include salmon, tofu (soybean curd), certain vegetables (broccoli), legumes (peas and beans), calcium-enriched grain products, lime-processed tortillas, seeds and nuts. If you do not regularly consume adequate food sources of calcium, a calcium supplement can be considered to reach the recommended amount. The current recommendations for women for calcium are for a minimum of 1,200 mg per day.
Breast cancer is the second most common cancer in the world and the most common among women. It is also among the ten most common chronic diseases of women, and a substantial contributor to loss of quality of life (Gronowski and Schindler, Table IV). Globally, it accounts for 25% of all cancers. In 2016, breast cancer is the most common cancer diagnosed among women in both developed and developing countries, accounting for nearly 30% of all cases, and worldwide accounts for one and a half million cases and over half a million deaths, being the fifth most common cause of cancer death overall and the second in developed regions. Geographic variation in incidence is the opposite of that of cervical cancer, being highest in Northern America and lowest in Eastern and Middle Africa, but mortality rates are relatively constant, resulting in a wide variance in case mortality, ranging from 25% in developed regions to 37% in developing regions, and with 62% of deaths occurring in developing countries.
Cervical cancer is associated with human papillomavirus (HPV), which has also been implicated in cancers of the vulva, vagina, anus, and oropharynx. Almost 300 million women worldwide have been infected with HPV, one of the commoner sexually transmitted infections, and 5% of the 13 million new cases of cancer in the world have been attributed to HPV. In developed countries, screening for cervical cancer using the Pap test has identified pre-cancerous changes in the cervix, at least in those women with access to health care. Also an HPV vaccine programme is available in 45 countries. Screening and prevention programmes have limited availability in developing countries although inexpensive low technology programmes are being developed, but access to treatment is also limited. If applied globally, HPV vaccination at 70% coverage could save the lives of 4 million women from cervical cancer, since most cases occur in developing countries.
In addition to diet, exercise and other lifestyle factors can also play an important role in bone health. Smoking and drinking too much alcohol can increase your chances of developing osteoporosis, while weight-bearing exercise (such as walking, dancing, yoga, or lifting weights) can lower your risk. Strength or resistance training—using machines, free weights, elastic bands, or your own body weight—can be especially effective in helping to prevent loss of bone mass as you age.
