Are certain parts of the body more inclined to create tumors? 

Why? Liver and fat tissues in breasts and prostate are sensitive to carcinogens and toxic substances settle in fat tissues. Endocrine Destroying substances (plastics) affect our hormonal balance. Air pollution, chemical fumes, weak immune system and metal toxins are contributing factors in lung cancer. Genetic data for these 3 cancers are well identified. Assumption: Female/Male, over 50 yrs of age, on western diet, lives in Northern hemisphere, have families with cancer, diabetes and polyps, prone to allergies (lack zinc), digestive disorders, high dairy and sugar consumption (low magnesium and calcium,iron) and had utilized a few drugs before.  With weakening immune system as we age, we are more likely to be prone to cancer and infectious organisms such as parasites can live for many years. Over time, they multiply and where there are cancer, parasites abound.

COPKL Risk Factor

COPKL Risk Factor = Blood sugar (0.2) + history (0.1) + sugar/processed foods consumption (0.1) + Exercise and sun exposure (0.1) + number of medications (0.1) + obesity/night time worker (0.1) + exposure to copper,fungus,molds,aflatoxins , parasites (0.2) + genes (0.1) 

Exposure to copper,fungus,molds,toxins, smoking,alcohol,narcotics, aluminum, air pollution, char broiled meat, aflatoxin, virus,bacteria, parasites,caffeine, medications. 

Genes: 0.2 = MSH2, MLH1, MSH6, PMS2, PMS1, TGFBR2, MLH3 , RCC, APC, HPC1, tmprss2-erg , TMPRSS2-ETV1/4, HBOC,BRCA,BRCA2,BRCA1
