Clinical trials are an important way to improve treatment for people with cancer. While most are continuing during the COVID-19 pandemic, the period of time that clinical trials are available and recruiting may change quickly. If you would like to get involved in a clinical trial, speak to your treatment team or the health service where the clinical trial is being undertaken, to confirm it is open and appropriate for you. For cancer information and support, call Cancer Council's experienced cancer nurses on 13 11 20 Monday to Friday from 9am-5pm.
