For pancreatic cancer, Dr. Klein reviewed the risk factors including tobacco use, diabetes mellitus, obesity, alcohol consumption, pancreatitis, allergies, and familial history of cancer [43] while also determining that typical tumor suppressors for this cancer type include BRCA2 DNA repair-associated (BRCA2), BRCA1 DNA repair-associated (BRCA1), and CDKN2A [43]. Here, BRCA1 is linked to obesity due to melanocortin 4 receptor deficiency.
