You may also be interested in Dr. Bruce Ame’s “Triage Theory of Nutrtion” - basically, chronic deficiencies of nutrients makes your body prioritize short term survival over long term, and these trade offs bear consequences in the long run:

Ames had become well aware that many micronutrient (vitamins and minerals) deficiencies are associated with chromosome breaks and cancer in humans, such deficiencies having caused DNA damage in rodents or human cells in culture. It had also been established that chromosomal breaks cause early aging. As a result Professor Ames proposed that DNA damage and late onset disease are consequences of a ‘triage allocation mechanism’ developed during evolution to cope with periods of micronutrient shortage.

Thing to keep in mind is that cancer, although given a single label, have multiple causes depending on where it originates.

Thus some forms are more related to lifestyle, while others more related to genetic inheritance.
