Risks And Benefits Of Breast Cancer Screening: BreastScreen WA Cohort Study Of Overdiagnosis And Breast Cancer Mortality
Funder

Funding Amount
$201,524.00
Summary
Overdiagnosis is the major downside of screening for breast cancer. This occurs when screening detects cancers that would not have caused symptoms in the woman's lifetime. This study aims to quantify the amount of overdiagnosis that occurs in the Australian breast cancer screening program (BreastScreen)
Cancer Risks From Low-dose Ionising Radiation Following Diagnostic Medical Procedures

Funding Amount
$750,579.00
Summary
Our study investigates cancer risk following exposure to low doses of ionising radiation from medical procedures. Our first major paper linked over 800,000 CT exposures to cancer outcomes in a cohort of almost 11 million young Australians, and found that CT exposure predicted an increased incidence of leukaemia and most solid cancers. In our ongoing work we will incorporate nuclear medicine and other diagnostic x-rays, and estimate radiation dose for individual procedures and to specific organs.
Improving Efficiency Of Surveillance Colonoscopy For Colorectal Cancer Prevention

Funding Amount
$643,123.00
Summary
Greater awareness of bowel cancer screening has led to increased demand and waiting times for colonoscopy. National guidelines recognise the need for research to identify the best use of colonoscopy to ensure health funds are directed where they are needed. This study aims to identify how often colonoscopy is required for the best patient outcomes. Data about cancer and death will be linked to hospital and laboratory data to identify which patients need more or less surveillance colonoscopies.
Statistical Analysis Of An International 10 Year Prospective Family Study Of Gene-environment Interactions On Risk Of Female Breast Cancer.

Summary
This study will provide new and credible information on how the effects of environmental and lifestyle factors on breast cancer risk depend on a woman's underlying genetic susceptibility using a large, international 10 year prospective family study.
Do Breast Cancer Risk Factors Differ According To Underlying Genetic Susceptibility? A Pooled Analysis Of Prospective Studies From The NCI Cancer Cohort Consortium
Funder
National Health and Medical Research Council
Funding Amount
$418,581.00
Summary
We propose to use data from 23 international prospective cohort studies in the Cancer Cohort Consortium organised by the US National Cancer Institute to evaluate gene environment interactions for women who are at increased genetic risk of breast cancer. Our ultimate goal is to enhance the performance of clinical prediction tools and to develop targeted evidence-based strategies to mitigate the high absolute risk of breast cancer for women at increased genetic risk of the disease.
Exposure To High Dose Estrogens In Adolescence: Long Term Effects On Mammographic Breast Density

Summary
Breast density is a well established risk factor for breast cancer, and has been shown to be reversibly influenced by hormone exposures in adult life. As one of the important roles of sex hormones during puberty is mammary cell proliferation, it is plausible that exposures at this earlier life stage might have a sustained influence on breast tissue composition and density, and subsequent breast cancer risk. This project aims to increase our understanding of the influence of sex hormones in adole ....Breast density is a well established risk factor for breast cancer, and has been shown to be reversibly influenced by hormone exposures in adult life. As one of the important roles of sex hormones during puberty is mammary cell proliferation, it is plausible that exposures at this earlier life stage might have a sustained influence on breast tissue composition and density, and subsequent breast cancer risk. This project aims to increase our understanding of the influence of sex hormones in adolescence on breast cancer risk by testing the hypothesis that exposure to large doses of sex hormones during adolescence has long-term effects on mammographic density. This will be done by comparing the mammographic densities of women who were treated with high doses of estrogen for tall stature during adolescence with women who were similarly assessed for tall stature but not treated. No previous study in humans has examined the long-term effects on breast tissue of high dose estrogen exposure at this early life stage. This is not surprising, given the difficulty in finding a suitable exposed population. This cohort of women, assessed or treated for tall stature, provides us with a unique opportunity to examine these influences. This research will add to our understanding of the influence of sex hormones in adolescence on mammographic density and breast cancer risk. If hormonal factors in adolescence are shown to influence mammographic density, this may lead to new avenues for breast cancer prevention efforts that are targeted much earlier in life. This information may lead to new research directions examining adolescent hormonal exposures (both endogenous and exogenous) and their influence on breast tissue.Read moreRead less

Summary
This proposal aim to follow up evidence from a number of studies that genetic and non-genetic markers of hormonal action in different periods of a man's life are associated with prostate cancer risk using a collection of three large, independent epidemiologic studies on prostate cancer named the Prostate Cancer Program.

A principal objective is to collect exposure data on acne and digit ratio, and genotype cases and controls across the studies of the Prostate Cancer Program for common genetic variants in 4 candidate genes in the hormonal pathway. The established risk factors for prostate cancer are only age, race and family history. We anticipate that this project will cast light on the role of hormones in prostate cancer and that we will identify new markers of risk of prostate cancer and markers of disease aggressiveness. These outcomes will help us identifying men who are at risk for prostate cancer to target screening and surveillance, and plan prevention strategies. Furthermore, they will also form the basis for research on treatment targets.Read moreRead less

The findings from this research will inform the development of public health policy on the most cost-effective utilisation of resources for preventing cervical, anogenital and head/neck cancers, and genital warts, in women and men, due to human papillomavirus (HPV). We will evaluate strategies for using emerging screening and vaccine technologies to prevent HPV-related disease, and assess potential adverse outcomes of vaccination. Men are currently not covered by routine vaccination or screening programs; this research will assess the benefit to men of vaccinating women only, and will consider the impact of vaccination and other interventions targeted towards men.Read moreRead less

This novel and important study will, for the first time in Australia, identify the extent and effects of loss of skilled workers from the workforce because of a diagnosis of breast, prostate or colorectal cancer and will lead to the development of new interventions that help people to recover from cancer. This project is critical to help advance health and labour policies in Australia which currently faces an ageing population, global economic unrest and rising unemployment.Read moreRead less
