Cancer how many people affected

Globally, no. The share of people with cancer even when corrected for ageing has been slowly increasing in recent decades. Global cancer prevalence has risen from 0. In some countries — the US, for example — the age-corrected prevalence has been fairly constant in recent decades with the rate of new cases actually falling. If death rates are falling but prevalence is rising or constant, then it must be the case that people with cancer have better or longer survival rates.

We see this clearly in the USA when we look at the change in five-year survival rates across cancer types. This is shown in the chart as the change from to Here we see that on aggregate five-year survival rates for all cancers increased from But we also see significant differences not only in start or end survival rates, but the change over time.

Prostate cancer has close to 99 percent five-year survival, but has also seen major progress from a rate of 69 percent in the s. In contrast, pancreas has low five-year survival rates at 8. Defining the exact attribution of each is difficult, and varies depending on cancer type. But there have been some studies which have attempted to do so. Scott Alexander published a very good overview of the relative impact of detection versus treatment here.

One way to test whether survival rates only increased from early diagnosis is to look at how survival has changed for each stage of cancer: if detection was the only improvement then we would see no increase in survival rates in later cancer stages.

National cancer statistics published by the US government show increases in survival rate within all stages from very early to late-stage.

Other studies focused on specific cancer types show similar results. Tumours have gotten smaller in recent decades — the result of earlier detection. Studies have shown that this can account for a significant share of survival improvements: one study attributed early detection as 61 percent and 28 percent of improved survival in localized-stage and regional-stage breast cancer, respectively 7 But even when correcting for size and early detection, we have seen improvements.

In this charts, we provide the widest coverage across countries of five-year survival rates by cancer type. This data was published in the The Lancet in by Allemani et al. The three maps below show how the five-year survival rates for lung, breast and liver cancer vary across the world. This data is again from Allemani et al.

In breast cancer, higher income countries in particular across North America, Europe and Oceania tend to have five-year survival rates over 80 percent in This is almost double that of the lowest nation with available data in — Jordan — at only 43 percent. Compared to breast cancer the five year survival rates for liver cancer are much lower around he world. The lowest survival rate in was in Romania with just 2. In these two charts we see that the five-year survival rates — following diagnosis — are lower in poorer countries.

Especially for breast cancer survival rates are lower in poorer countries. The relationship between lung cancer survival rate and average is less strong. There is significant variability in five-year survival rates between countries of a similar income, but the lowest survival rates are again reported from the poorest countries. Are cancers caused by genetic factors, or determined by external factors such as behavioral, lifestyle and environmental exposure?

The relative contribution of genetic factors DNA replication and tissue type versus external exposure has been a dominant topic within cancer research. The outcomes of such studies are highly important — if genetic factors are found to be dominant then early detection and understanding of the relative vulnerability of different DNA and tissue variations arguably present the best opportunity to reduce cancer burden. In contrast, if external and environmental risk factors dominate, then lifestyle choice which reduces risk exposure is crucial for this reduction.

This study therefore argued that, beyond some cancer types which are deterministic D-tumors and can be reduced through lifestyle factors or vaccines , the most promising approach to reduction of cancer deaths across most cancers replicative, R-tumors is early detection. This paper has been highly contest within the scientific literature. A number of later publications in Science provided a rebuttal to these conclusions, suggesting analytical flaws in the prior analysis, and epidemiological evidence which suggests otherwise.

Wu et al. The Global Burden of Disease GBD study attempt — using risk-exposure relationships — to provide attribution of certain risk factors to disease burden and mortality outcomes. In the chart we see IHME estimates of the share of global cancer deaths which are attributed to one of these major risk factors.

For example, 84 percent of tracheal, bronchus and lung cancer deaths are attributed to risk factors such as smoking and air pollution. The remaining share of deaths we would therefore assume no attribution to risk factors, and would occur naturally in the absence of such risks i. Whilst cancer prevalence shows a positive relationship to income, death rates from cancer incorporate several factors: cancer prevalence, detection and treatment.

When we compare cancer death rates across income we see no strong relationship between these measures. There is also no correlation between the level of income inequality in a country and the cancer death rate. These measures vary in the information they provide.

This is an important metric for a number of reasons, including the need for management and provision of adequate health services which is dependent on the total societal burden, not just the incidence or risk for a given individual. However, total number of cancer deaths fails to correct for population size and age.

Cancer death rates correct for changes in population size , age-standardized death rates correct for population size and age structure. Age-standardization therefore gives a more indicative measure of the prevalence and incidence of underlying cancer risk factors between countries and with time without the influence of demographic and population structure changes.

Summary Cancer is one of the leading causes of death. As the world population is growing and aging the global number of cancer deaths is increasing. Adjusted for the increase and aging of the world population the rate of cancer deaths has declined slowly — the same is true for many countries.

The world is making very slow progress. Lung cancer kills most people and smoking is largely to blame. As the share of smokers is declining the rate of lung cancer deaths is following. Cancer death rates for US over the last century show that we are slowly making progress against a number of different cancers.

Five-year survival rates are rising in the US. Cancer survival rates differ strongly between different countries across the world. Cancer survival rates often much lower in poorer countries.
