Answer: In Australia, the lifetime risk of developing bowel cancer before the age of 75 years is around 1 in 18 for men and 1 in 26 for women, and this is one of the highest rates of bowel cancer in the world.
Answer: In 2003, an estimated 57,100 people will die from colorectal cancer. Although screening could find precancerous growths (polyps), which lead to colorectal cancer, screening rates in the United States remain low.
Answer: Large doses of vitamins, fiber, and green tea are among therapies tried. Avoiding cigarettes and alcohol may be helpful. Before initiating any alternative therapies, the patient is wise to consult his or her physician
Answer: digital rectal exam (DRE). The DRE includes manual examination of the rectum, anus, and the prostate. During this examination, the physician examines the anus and the surrounding skin for hemorrhoids, abscesses, and other irregularities.
Answer: High-fiber diets may help lessen exposure of the colon lining to carcinogens from the environment, as the transit time through the bowel is faster with a high-fiber diet than it is with a low-fiber diet.
Answer: By the time the primary is originally detected, it is usually larger than 0.4 in (1 cm) in size and has over one million cells. This amount of growth itself is estimated to take about three to seven years.
Answer: A nine panel drug test may or may not be very accurate. The accuracy is directly related to the quality of the lab and/or sample for testing. "Nine Panel" refers to how many drugs(panels) the test is checking for. It seems to me that urine tests are less accurate than hair tests and hair tests less than blood tests. All three can show false positives, but only two can be tricked.
Answer: At home, after having a bowel movement, the patient is asked to swipe a sample of stool obtained with a small stick on a card. After three such specimens are on the card, the card is then easily chemically tested for occult blood also.
Answer: Occult blood indicates the presence of red blood cells which are normally not seen in urine. This usually indicates either physical trauma to the spleen or lower abdomen, or urinary tract infections which allow the passage of these cellular elements. Note that taking anticoagulants like Coumadin Amy also cause this.
Answer: Normally there is no protein detectable on a urinalysis strip. Protein can indicate kidney damage, blood in the urine, or an infection. Up to 10% of children can have protein in their urine. Certain diseases require the use of a special, more sensitive (and more expensive) test for protein called a microalbumin test. A microalbumin test is very useful in screening for early damage to the kidneys from diabetes, for instance.
"Occult blood" simply means "hidden" blood; blood that is not visible, but is still present. Normally there is no blood in the urine. Blood can indicate an infection, kidney stones, trauma, or bleeding from a bladder or kidney tumor. The technician may indicate whether it is hemolyzed (disolved blood) or non-hemolyzed (intact red blood cells). Rarely, muscle injury can cause myoglobin to appear in the urine which also causes the reagent pad to falsely indicate blood
Answer: §Small polyps were not discovered before they become cancerous.§Diets high in fat, alcohol, protein, calories, and red and white meat. Colon cancer is more common in the U.S. and other Western countries where people eat foods high in saturated fat and low in fiber.§Not eating foods rich in fiber. Dietary fiber is thought to protect against colon cancer because fiber-rich food is digested faster. Therefore undigested food remains in the colon for a longer period of time.
Answer: In late 2003, a team of researchers identified the specific location on a human chromosome by analyzing blood samples from 53 families in which at least one member had a colon cancer or precancerous colon polyp.
