Newly-Discovered Human Organ May Help Explain How Cancer Spreads

A newly discovered network of fluid-filled channels in the human body may be a previously-unknown organ, and it seems to help transport cancer cells around the body.

This discovery was made by chance, from routine endoscopies – a procedure that involves inserting a thin camera into a person’s gastrointestinal tract. Newer approaches enable doctors to use this procedure to get a microscopic look at the tissue inside a person’s gut at the same time, with some surprising results.
One team had expected to find that the bile duct is surrounded by a hard, dense wall of tissue. But instead, they saw weird, unexplained patterns.

But as well as protecting organs, the network may also aid the spread of cancer. When the team looked at samples taken from people with invasive cancers, they found evidence that cancer cells that had worked their way out of their original tissues could find their way into these channels, which took them directly to the lymphatic system. “Once they get in, it’s like they’re on a water slide,”

“We have a new window on the mechanism of tumor spread.”

Scientists and technologists are now investigating whether analyzing the fluid in these newly-discovered channels might lead to earlier diagnosis of cancers. They think the organ might also be involved in other problems, including edema, a rare liver disease, and other inflammatory disorders.

Basics of Blood

Image
Blood is a specialized body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues forming blood clots to prevent excess blood loss carrying cells and antibodies that fight infection bringing waste products to the kidneys and liver, which filter and clean the blood regulating body temperature The blood that runs through the veins, arteries, and capillaries is known as whole blood, a mixture of about 55 percent plasma and 45 percent blood cells. About 7 to 8 percent of your total body weight is blood. An average-sized man has about 12 pints of blood in his body, and an average-sized woman has about nine pints. The Components of Blood and Their Importance Many people have undergone blood tests or donated blood, but hematology - the study of blood -encompasses much more than this. Doctors who specialize in hematology (hematologists) are leading ...

Leukemoid Reaction and Diagnosis (D/D from Chronic Myelocytic leukemia)

Image
  A  leukemoid reaction  is an increase in the white blood cell count, which can mimic leukemia. The  reaction  is actually due to an infection or another disease and is not a sign of cancer. Blood counts often return to normal when the underlying condition is treated. Sample Blood in EDTA is needed along with fresh blood smear. Definition If there is a persistent increase in the neutrophils, reactive and excessive leucocytosis with a count of 30,000 to 50,000 / µL, with the presence of immature and mature white cells in the peripheral the blood smear is called a Leukemoid reaction. Sometimes the lymphocytic reaction is maybe seen. This is not a primary marrow disorder, and this is due to the secondary to infections.   The count varies from 50,000 to 100,000/cmm. with immature cells. Blast cells in the peripheral blood smears are not seen which is helpful to differentiate from leukemia. Extremely eleva...
