Support for rare cancers is particularly problematic, as patients may be a long way from specialist treatment centres, and also from other patients with whom they might gain support and advice. The advent of the internet has allowed support groups for these rare cancers to emerge on a global basis, providing one to one and group oriented advice and support to patients and their families who may live on different continents, yet are able to share symptoms, experiences and advice, for example on diet or pain relief.
