✓Well SupportedCancer cells are fundamentally different from non-cancer cells due to their response to cell cycle signaling, not necessarily because they divide more quickly.✓Well SupportedBlood tests currently offer limited insight into cancer risk, except for future liquid biopsies detecting RNA, DNA, or proteins.✓Well SupportedObesity and its accompanying metabolic environment are the second leading environmental predisposition to cancer after smoking.✓Well SupportedCancer is a metabolic and mitochondrial dysfunction, not a genetic disease.Partially Supported

Blood tests currently offer limited insight into cancer risk, as most cancers result from somatic, not germline, mutations, with exceptions like BRCA and Lynch syndromes.

◐Partially SupportedCancer cells consume high glucose and produce aberrant lactate even with sufficient oxygen.

✓Well SupportedHigh levels of circulating insulin may be central to breast cancer development and growth because insulin is also a growth factor.

◐Partially SupportedMetabolic markers like glucose and insulin are key indicators for understanding an individual's risk of heart disease and can be applied to cancer risk assessment.

◐Partially SupportedBlood tests are primarily useful for assessing an individual's metabolic environment and predisposition to cancer.

◐Partially SupportedAn individual's underlying metabolic health and immune function significantly impact cancer risk.

✕Not SupportedBiomarkers CA 125 and CEA are not appropriate for cancer screening.

◐Partially SupportedCancer progresses when the immune system loses its ability to keep it in check.
