" Le cancer du côlon se développe à partir de la muqueuse du « gros intestin » ou côlon. Dans 70 % des cas, la tumeur se développe dans le sigmoïde (boucle située dans la fosse iliaque gauche). Les cancers du côlon et du rectum étant assez semblables, on les regroupe sous le terme de cancer colorectal. Il s'agit toujours d'une tumeur maligne ; adénocarcinome liebekunien, développé à partir de la muqueuse. C'est le second cancer, en termes de fréquence, chez la femme (après le cancer du sein) et le troisième chez l'homme (après le cancer du poumon et celui de la prostate)[1]." 
"The lifetime risk of developing colon cancer in the United States is about 7%. Certain factors increase a person's risk of developing the disease.[5] These include: Age-The risk of developing colorectal cancer increases with age. Most cases occur in the 60s and 70s, while cases before age 50 are uncommon unless a family history of early colon cancer is present.[6]. Polyps of the colon, particularly adenomatous polyps, are a risk factor for colon cancer. The removal of colon polyps at the time of colonoscopy reduces the subsequent risk of colon cancer. Environmental factors.[16] Industrialized countries are at a relatively increased risk compared to less developed countries that traditionally had high-fiber/low-fat diets. Studies of migrant populations have revealed a role for environmental factors, particularly dietary, in the etiology of colorectal cancers. One study found that "People who drink more than 30 grams of alcohol per day (and especially those who drink more than 45 grams per day) appear to have a slightly higher risk for colorectal cancer."[28] Another found that "The consumption of one or more alcoholic beverages a day at baseline was associated with approximately a 70% greater risk of colon cancer."

Comment ne pas vouloir manger et boire à table quand on avance en âge sédentarisé ? Comment résister aux menus attractifs qui sont trop souvent proposés au "troisième âge" en toute occasion: réunion professionnelle, fête familiale, excursion et voyage ? Rien ne vient freiner cette addiction nouvelle alimentaire et pourtant graisse et alcool ne font pas bon ménage ...
