PCaSO Eastbourne is part of the PCaSO Prostate Cancer Support Organisation, a charity managed entirely by volunteers, many of whom are prostate cancer patients. PCaSO has branches in Dorset, Hampshire and Sussex. PCaSO Eastbourne is part of the Sussex branch along with the Rustington, Pulborough and Brighton support groups. 

The aims of PCaSO are to improve the diagnosis, treatment, care and support of those affected by prostate cancer. It does this by raising awareness and offering information and support through newsletters and publications. Regular meetings are also held throughout the South coast region.

A national helpline is provided by ‘Tackle’ which is the National Federation of Prostate Cancer Support Groups to which PCaSO belongs.
