The silent disease: Breast cancer
Breast cancer is one of the diseases that make no distinction between the population of developed and developing countries and is the type of cancer with greater presence in women worldwide.
As for mortality from this disease, there are differences: in low-income countries occur most deaths because usually diagnosed in advanced stages of the disease, due to the lack of access to health services and little awareness for early detection (knowledge of signs and symptoms of early breast self-examination). Data from the World Health Organization (WHO, 2015c) indicate that each year 1.38 million new cases are diagnosed and 458,000 deaths occur from this disease.
According to the Pan American Health Organization (PAHO) in the Americas, the trend is similar, ie, breast cancer is the most common among women (29% of total cancer cases) and is the second leading cause of death from malignant tumors for this population, exceeded only by lung cancer (15 versus 18 percent); 2030, PAHO estimates more than 596,000 new cases and more than 142,100 deaths in the region, mainly in the area of Latin America and the Caribbean (PAHO, 2014th and 2014b).
Self-examination refers to a simple technique that should be performed monthly to detect changes in the shape or texture of the breast, areola or nipple, skin thickening or lumps under her, pits, nipple discharge, scaly skin or swollen, signs to which should see a doctor to rule out a possible tumor. While there is no medical consensus on its effectiveness, since there are tumors that because of its location and stadium can not be detected by this means, undoubtedly allows women to be alert to changes in your body and awareness regarding this disease (Breastcancer.org, 2012).
Some risk factors for cancer can be avoided, but many others do not. For example, both smoking and inheriting certain genes are risk factors for some cancers, but only you can avoid smoking. Regular exercise and a healthy diet may be protective factors for some cancers. Avoiding risk factors and increasing protective factors can reduce your risk, but this does not mean you will not get sick of cancer.
The following are the different ways to prevent cancer being studied:
Change your lifestyle or eating habits.
Avoid things that are known to cause cancer.
Taking medicine to treat a precancerous condition or to prevent this cancer.
