The site now includes a question and answer section. Questions sent to the site are answered personally by a member of Cancer Research UK's information team.
New features have also been added to the site's clinical trial database. The database is presented in plain English to help patients understand ongoing research.
Liz Woolf, head of CancerHelp UK, said that visitors to the site had said they wanted more information on past trials, so that they know about new treatments in the pipeline.
‘As well as introducing information on these trials, the website will also feature ongoing trial results,' she said.
