What Is Tumor Initiation?
The tumor incidence rate is the relative or frequency index obtained in a given year and in a certain area by taking the average of the total registered population as the denominator and passively collecting the total number of all confirmed malignant tumor cases.

- The tumor incidence rate is the relative or frequency index obtained in a given year and in a certain area by taking the average of the total registered population as the denominator and passively collecting the total number of all confirmed malignant tumor cases.
- Expresses the severity or severity of tumor prevalence in a certain area in a year.
- In general, indicators of the severity of chronic non-communicable diseases are prevalence, not morbidity. The exception is that although malignant tumors are chronic non-communicable diseases, but malignant tumors are chronic diseases with a low probability of occurrence. If the prevalence rate is used to reflect the degree of harm of such diseases, the sample size required for the current survey is too large, and the survey cost It is too high and prone to sampling errors. Therefore, the index reflecting the prevalence of malignant tumors does not require prevalence. Instead, the passive monitoring method of tumors with low monitoring cost and more accurate data collection is used to obtain the tumor incidence. The severity of the malignancy.
- Incidence of certain tumors
- The calculation method of a certain tumor incidence rate is only different from the aforementioned tumor incidence rate. The total number of individual tumors divided from the total number of malignant tumors in the year is used as the numerator, and the denominator is still the average of the total population in a given area.
- The incidence of tumors = [number of new cases of malignant tumors in an exposed population in a certain period of time / average population of the same period] × 100,000 / 100,000.
- Incidence of a certain tumor = [Number of new cases of a certain malignant tumor in the exposed population in a certain period of time / average number of the same period] × 100000 / 100,000
