Cancer Free Five Years

Cancer Free -

The survival rate of five years is usually calculated from time of diagnosis, a kind of survival rates for estimating the prognosis of a disease in particular. Relative survival rates five years describe the percentage of patients with a disease alive five years after their disease diagnosed, by dividing the age and sex corresponds to the percentage of the population in General, who are alive after five years. In General, cancer five-year absolute survival rates well below 100%, reflecting excess mortality in cancer patients than the general population. In contrast to the survival rate of five years of related, for the dispatch of the survival rates five years match or exceed 100% if cancer patients is equal to or even higher than the general population to survive. This pattern can occur if cancer patients can usually be cured, or if patients diagnosed with cancer are otherwise more privileged than the general population (E. g in relation to socio-economic factors or access to medical care). At first glance that seems counterproductive that were appreciated more than 100% relative survival rates for certain groups of patients. cancer free five years It is unlikely that this incident prostate cancer compared with the general population would increase the chances of survival. A more plausible explanation is that this trend is a selection of PSA screening effect is reflected, as screening tend less frequently disadvantaged population to be used, generally higher mortality. The survival rate at five years can be used to compare the effectiveness of treatments. Use of statistics on the rate of survival at 5 years is more aggressive disease, after diagnosing the shortest life expectancy (lung cancer, E. g.) and with a long service life as prostate cancer, less useful. Price improvements are sometimes attributed to improvements in diagnosis, further improvements in the prognosis. . . . . .
