Elaine Sleigh, a breast cancer patient, saw her tumours decrease by 65% due to research at The Christie NHS Foundation Trust. After initial treatment, she joined a trial for a new blood test to detect cancer cell DNA in the bloodstream. When cancer recurred, she participated in the PETRA trial, receiving a combination of targeted chemotherapy and an experimental drug, AZD5305, which is a PARP inhibitor. Elaine's condition improved, and she attributes her progress to the trials and positive attitude.
