2 nd general driving reason for growth passing in the United States 3 rd in every sex Approximately 6% of people in the US will build up a malignancy of the colon or rectum inside their lifetime 944,717 occurrence cases worldwide in 2000

Slide 3

Incidence rates for colorectal tumor vary by sub-locales

Slide 4

Vast lion\'s share of colorectal diseases are adenocarcinomas, which are gone before by adenomas or adenomatous polyps as a rule Only around 10% of adenomas will form into malignancies, a procedure that takes no less than 10 years

Slide 5

147,500 colorectal growth cases in 2003 105,500 colon 42,00 rectum 57,100 passings from colorectal growth Slight abatements in death rates since 1973 in both genders

Slide 8

Overall 5 year survival rate is 61.9% Differs by race, age, and dispersion of illness Survival rates are lower among than blacks than whites 52.8% versus 62.6% Survival rates are most astounding for confined malignancies

Slide 9

Incidence rates begin to increment after age 35 with a fast increment after age 50, when more than 90% of colorectal tumors create

Slide 10

Overall age-institutionalized frequency rates were 65.1 for each 100,000 for men and 47.6 for every 100,000 for ladies Male-female ratio=1.37 Mortality rates were likewise higher in men than ladies 25.4 versus 18.0 for every 100,000

Slide 11

Race and Ethnicity Higher rates and mortalities among blacks than whites Socioeconomic status Possible relationship between low SES and colorectal disease mortality

Slide 12

Fruit, Vegetables, and Fiber Majority of case-control ponders have demonstrated a relationship between higher admission of vegetables and lower tumor chance Recent vast companion contemplates have demonstrated powerless or non-existent relationship amongst fiber and colon disease chance Folate Higher admission of folate has been generally reliably connected with lower colon malignancy chance

Slide 13

Calcium Avoidance of low admissions of calcium may minimize danger of colon growth Fat, Carbohydrates, and Proteins Excess vitality consumption prompting to corpulence expands the danger of colon malignancy Possible relationship of red meat with expanded hazard

Slide 14

Higher BMI is connected with an expanded danger of colon tumor Approximately twofold higher hazard in people who are overweight or stout

Slide 15

Individuals who are all the more physically dynamic have a diminished danger of colon disease Some advantages seem, by all accounts, to be free of BMI Studies have demonstrated dosage reaction relationship between physical movement and colorectal malignancy Highest hazard saw in people who are both physically idle and have high BMIs

Slide 16

Alcohol Somewhat dubious, yet gives the idea that high liquor admission builds chance Tobacco Most reviews show abundance chance in smokers

Slide 17

Familial Adenomatous Polyposis (FAP) Rare, acquired, autosomal prevailing disorder Causes event of different colorectal adenomas in people in their 30s that untreated, will prompt to malignancy Hereditary Nonpolyposis Colorectal Cancer (HNPCC) Autosomal overwhelming acquired issue

Slide 18

Family history of colorectal disease History of adenomatous polyps Several low-penetrance qualities Type 2 Diabetes Growth calculates High insulin-like development components Hyperinsulinemia

Slide 19

Inflammatory Bowel Disease Gallstones and Cholecystectomy Glucose Intolerance, Non-Insulin Dependen Diabetes Mellitus Acromegaly

Slide 20

Prevention of smoking Prevention of weight pick up Maintenance of a sensible level of physical action in adulthood Limit red and prepared meats, high-fat dairy items, exceptionally refined grains and starches, and sugars

Slide 21

Early discovery and expulsion of colorectal adenomas decreases danger of disease Screening is prescribed for grown-ups starting at age 50 Fecal mysterious blood test (FOBT) every year Sigmoidoscopy like clockwork Or Colonoscopy at regular intervals For high hazard people, screening ought to be custom fitted to their normal hazard

Slide 22

Research on modifiable hormonal pathways connected with more serious hazard Role of micronutrients, for example, calcium and folate and different specialists Identification of hereditary weakness
