The International Psycho-Oncology Society (IPOS) is a professional membership society that was founded in 1984 to foster international multidisciplinary communication about clinical, educational and research issues related to two main psychosocial dimensions of cancer care:

- Response of patients, families and staff to cancer and its treatment at all stages
- Psychological, social, behavioral and spiritual factors that affect quality of life, tumor progression and survival
