Title
Ultra-processed food consumption and all-cause and cause-specific mortality among US cancer survivors
Summary
The number of cancer survivors is rabidly increasing worldwide. In the USA, there are around 16.9 million peoples who are currently living with cancer (1). Given the huge burden of cancer survivors globally, it is necessary and urgent to identify modifiable risk factors for improving the prognosis of this population.
Dietary habits have been indicated to play an important role in determining the prognosis of cancer survivors. For example, a recent meta-analysis found that high vegetable consumption was inversely associated with overall mortality in survivors of head and neck (2). Ultra-processed food consumption has been associated with an increased risk of death. However, to our knowledge, no prospective cohort study has accurately evaluated the potential association between ultra-processed food consumption and mortality in cancer survivors. Hence, we sought to examine this potential association in overall as well as breast, colorectal, lung, and prostate cancer survivors.

Aims
(1) To examine the potential associations between ultra-processed food consumption and all-cause and cause-specific mortality in survivors of overall cancers.
(2) To examine the potential associations between ultra-processed food consumption and all-cause and cause-specific mortality in breast, colorectal, lung, and prostate cancer survivors.
