 It’s beans main alkaloid is the purine caffeine
 White and black tea also contain caffeine
 Examined based on their consumption quantities and how often

5. CANCER LOCALIZATION AND THE
INTERACTION OF COFFEE
 Lung cancer is a malignant tumor that destroys the healthy lung
tissue around it
 Lung cancer is linked to coffee’s caffeine
 Coffee contains compounds that reduce the risk of Upper
Gastrointestinal (UGI) Tract cancer
 Coffee’s temperature when ingested may affect
 Coffee beans contain several phenolic compounds with antioxidant
properties

6. CANCER LOCALIZATION AND THE
INTERACTION OF COFFEE
 Inverse association between coffee and oral, pharyngeal, and
esophageal cancer
 Speculation that caffeine may increase breast cancer risk
 Pregnant women who drank coffee may decrease the risk of son’s
cryptorchidism or undescended testicle
 Maternal coffee consumption might decrease the risk of testicular
cancer

7. CONCLUSION
 None of the five reviewed studies of had consistent results
 Most of the results were expressed as: coffee may increase or
decrease…
 Overall in most cases coffee helps to prevent the risk of acquiring
different types of cancer
 More studies have to be made and published
