Who is selected to provide a blood sample?
A small number of participants (10 - 20% percent) will also be invited to provide a blood sample, after they have completed the questionnaires and saliva sample. Although a saliva sample has been provided for DNA analysis, it is believed that the additional biomarkers available in blood (eg. plasma proteins (albumin, globulins), serum, vitamins, phospholipid membrane fatty acids, proteins, circulating endogenous hormones) may enable researchers to better understand the development of cancer and other chronic diseases.
Participants are chosen based on what is reported to us in the family history questionnaire. These participants have at least one close relative with cancer.
The ABC study seeks to understand the role that genetic and lifestyle factors play in the health and development of chronic diseases.
