Find out how we produce our information|
There are over 200 different types of cancer. We don't know all the causes for every one of these cancers, but we do know about some. It’s important to remember that for many cancers there may be more than one cause.
Learn how factors such as age, smoking, sun exposure and an unhealthy diet can increase the risk of developing certain cancers and watch our video about diet
Get information about how having a poor immunity, for example if you have HIV or have had an organ transplant, can increase the risk of certain types of cancer such as lymphomas, skin cancer and cervical cancer
Get information about asbestos, chemicals and natural radiation, which can cause some types of cancer
Find out about viruses, such as HPV, that may be linked to certain types of cancer.
