Low immunity

Some types of cancer are more likely to occur in people who have poor immunity.

People with a lower immunity may have:

  • had an organ transplant and are taking drugs to suppress their immune system to prevent the organ being rejected by the body
  • reduced immunity because of HIV (human immunodeficiency virus)
  • rare medical syndromes that reduce immunity.

People with poor immunity are more likely to develop lymphomas and certain types of skin cancer (particularly non-melanomas). They are also more at risk of cancers that are influenced by a virus or bacteria, such as cancers of cervix, some anal and genital cancers, and some cancers of the stomach and liver.
