Study in male smokers continues to provide clues into the causes and prevention of multiple cancers
...opherol (a form of vitamin E) and beta-carotene (a precursor of vitamin A), would prevent lung cancer and other cancers in a group of 29,133 male smokers in Finland. The participants, ages 50 to 69, provided information such as height, weight, and medical factors, as well as an extensive food frequency questi...No justification for colposcopy in screening of young women for cervical cancer

According to Dr. Gandy, APP can be broken down in two ways: "Bad cleavage" releases toxic amyloid-beta; "good cleavage" destroys it.
