This project aims to improve our understanding of childhood cancer by using a detailed dataset from the Avon Longitudinal Study of Parents and Children (ALSPAC), which contains extensive information about parents and their children. We will also use the ALSPAC data to identify risk factors, particularly related to maternal breastfeeding, and its impact on childhood cancer. Ultimately, our goal is to use this information to train the next generation of PHD students who study statistical genetics and genomics and enhance our knowledge of general health of children and what might increase the risk of cancer in children, helping to inform future research and potentially guide preventative measures.
