Fish oils block chemotherapy drug

Fats found in fish oil supplements can stop chemotherapy drugs working, according to researchers.
Writing in the journal Cancer Cell, they advise cancer patients not to take the supplements. The two fatty acids involved, which are also produced by stem cells in the blood, lead to tumours becoming immune to treatment.

Cancer Research UK advised patients to ask their doctor whether they would be affected. Scientists in the Netherlands were investigating how tumours develop resistance to treatments.
