Screening for breast cancer
TLDR
Modelling is developed to assess the effect of the frequency and sensitivity of the screening program on the non-recurrence rate for breast cancer and various recommendations on screening design are given.Abstract:
Summary
It is widely recognized that early detection of malignant cancer is associated with increased survival prospects. If regular examinations are given, then in the case of breast cancer, there is a high chance of locating lesions before they would normally be found by the patient. Such examinations are called screenings and may involve several detection modalities. The two main parameters in the design of a screening program are the frequency of examination and the sensitivity of the detection modality. Models are developed in this paper to examine the effect of screening on the sue of tumors at the time of detection. They are then used to assess the effect of the frequency and sensitivity of the screening program on the non-recurrence rate for breast cancer. As a result of the modelling, various recommendations on screening design are given.read more

TL;DR: The most frequent reported barriers for BSE were lack of knowledge, considering oneself not at risk and the absence of doctor advice, which need to be taken into account in intervention efforts.

Tobacco smoke exposure and breast cancer risk in Thai urban females.
TL;DR: Passive smoke exposure may be one important risk factor of urban female breast cancer, particularly, from a spouse or workplace, and highlights the importance of avoiding tobacco smoke exposure as a key measure for breast cancer prevention and control.

A review of the technical features of breast cancer screening illustrated by a specific model using South Australian cancer registry data.
TL;DR: Some of the parameters which describe the pattern of this disease in the South Australian female population are estimated and the underlying model is used to estimate the impact of various screening designs on the efficacy of a variety of breast cancer screening programmes.

Cancer of the breast: size of neoplasm and prognosis.
TL;DR: It is concluded that size may not necessarily relate to “earliness” or “lateness” of a tumor, nor is it as consequential to the fate of the patient as are other factors relative to the tumor and /or host that may be present from its inception and which determine the development of metastases.

The theory of periodic screening i: lead time and proportion detected
TL;DR: A stochastic model for a periodic screening program is presented in which the natural history of a chronic disease is assumed to follow a progressive path from a preclinical state to a clinical state.

The theory of periodic screening II: doubly bounded recurrence times and mean lead time and detection probability estimation
TL;DR: In this paper, the distributions of doubly bounded preclinical state forward and backward recurrence times of the stochastic screening model were derived and properties of these distributions were used to obtain an expression for estimating the mean lead time gained by screening, an alternative theoretical expression for the mean leading time and an equation for calculating an estimate of the probability of detecting preclinical disease.
