We concentrate our efforts on cancers that fall outside of the ‘big four’
We concentrate our efforts on cancers that fall outside of the ‘big four’ – lung, breast, bowel and prostate cancers. If you have any other type of cancer, then becoming a RareCan member might be right for you.
Even if you do have a ‘big four’ cancer type, there are sub-types of these cancers that are considered to be rare. If you are not sure if your cancer ‘counts’ as rare, please contact us or simply sign up and we will be able to guide you. You can also search for your cancer type in the box below or browse our A to Z of rare cancers below that.
Is my cancer rare?
By Professor Andy Hall
Until recently the only way of splitting cancers into various types was by describing where in the body it first started. This relatively simple approach..

Rare cancer treatments
By RareCan Team
Detailed articles explaining the different types of treatments that exist for rare cancers and for cancer in general. More to be added in future.
Rare cancer information packs
Detailed information about individual rare cancers. More to be added in future.
