Lee is an Executive Member of Cancer Voices NSW (CVNSW) and Cancer Voices Australia (CVA). She is the leader and coordinator of the Consumers in Research program for CVNSW and CV Australia. In 2000, Sally Crossing founded Cancer Voices to advocate on behalf of all people with cancer. CVNSW, in conjunction with the Cancer Council NSW, runs advocacy and research training for cancer consumers and supports consumer representation on a range of committees. It has been influential in improving cancer diagnosis, treatment, care, information and the direction of cancer research in Australia. Lee was diagnosed with an aggressive Grade 3 cancer at age 53. Following surgery to remove the tumour, she undertook an 18-month treatment program to reduce the risk of a reoccurrence. Unfortunately, she suffered significant side effects from all three treatments. Realising that the cancer journey doesn't stop when treatment finishes led Lee to look for ways she could connect and advocate with others who shared the same experience. After a 40-year career in education she joined CVNSW and has since taken on various consumer roles on research projects and committees. She is presently a member of the Faculty of Radiation Oncology Council (RANZCR), the Radiation Therapy Advisory Group and the Centre for Research Excellence DISCOVER TT, at Menzies School of Health Research.
