The information about the "dramatic" increase in breast cancer, I wrote about in my last post here are based on data on the incidence, ie the number of new cases (reported to the Cancer) in relation to the population. Two other measures of the burden of disease is the number of deaths by disease as the underlying cause of death (mortality) and the number of hospitalized moles with the disease moles as the main diagnosis in relation to the population. How have these measures been developed for breast cancer in parallel with the increasing incidence over the past decade? The chart below shows the average incidence, frequency and inpatient mortality from breast cancer by age group among women in Sweden in 2008-10 compared with the corresponding numbers 1998-2000.
The chart (click to enlarge) shows the average incidence, frequency of hospitalization and mortality in breast cancer years 2008-10 divided by the corresponding data for 1998 to 2000, among Swedish moles women in the age range from 25-29 to 85- years. moles Data available through the National Board Statistics database.
The incidence has, in accordance with what has been previously discussed, increased in most age groups, but not in 50-60s. The mortality rate has decreased in all age groups under 65 and remained unchanged in the higher age groups. Inpatient population has declined in the age groups between 35 and 65 years, but remained unchanged among older and younger. How will these diverging trends interpreted? If the increase in incidence would reflect a real increase in the disease, it could be argued that in and of itself moles did not have to mean that the mortality also increased, as eg better treatment could possibly prolong life among those affected. However, when the number of hospitals that cared not increase, a more reasonable explanation be that the increased age-specific incidence consists of cases detected moles at an early stage and do not lead to much additional hospitalization.
More specifically, we see that there has been a significant relative moles increase moles in incidence in the youngest age groups (between moles 25 and 35 years). Meanwhile, the reduction in mortality evident in the next few age groups (between 35 and 45 years), and even inpatient century has decreased in these age groups. One hypothesis that could be reasonable as an explanation for this is that health moles care has become progressively better at identifying women at risk for early breast cancer (due to such things as genetic factors), although there is no screening the general population before 40 years age, and that it leads to the disease can be detected earlier and treated more effectively among them. It can be expected to lead to both increased the reported incidence in the youngest age groups and to reduce the need for hospital treatment for advanced cancer and reduced mortality in the age groups immediately above, which is consistent with the observed pattern. moles The increased incidence after age 60, on the other hand, was not accompanied by any obvious changes either in terms of hospitalization rates or mortality. I wrote this on February 20 that the marked increase in incidence between 65 and 75 years of age might possibly also be explained by increased screening, but maybe not modern diagnosis and treatment postpone mortality in cancer what seems like forever (Riggs 1991).
My general impression is that the media attention surrounding breast cancer was greater in Sweden in the early part of the last decade compared to the past few years. In the mid-00s came the campaigns of female circulatory disease, I've written a lot about this before. They were perhaps in turn most active around 2007-08 - since has perhaps the most media debate around these diseases concerned different kostmodellers excellence or harmfulness. In part, they were a reaction to breast cancer received disproportionate attention relative moles to other public health problems. They also highlighted the key issues that the under-representation of women in epidemiological and clinical studies. At the same time seemed their approach in the media largely moles be modeled precisely breast cancer campaigns, and they took great extent the problematic features of these as pointed out in the article (Lantz and Booth 1998) I mentioned in my last post here - disproportionate focus on young women and a tendency to present it as an "epidemic" (see my post here 8 March 2012 and 14 May 2009). moles In terms of both disease groups, the latter moles might be justified if we compare western populations of hunter / gatherer culture, but it does not have much support if we look at developments moles in Sweden during the time we had comprehensive statistics on mortality and incidence.
