Carcinoma
An enlarging heterogeneous hypodense mass in the right hepatic lobe may indicate a liver tumor. Further imaging studies and possibly a biopsy would be needed to determine the nature of this mass. Treatment options would depend on the type of tumor and the extent of its spread.
It means that the hepatic tumor cells closely resemble the real and "healthy" hepatic cells. When talking of tumors, the term "well-differentiated" is a "good" indicator. Cells "differentiate" one from the others in order to accomplish their function... for example, pneumonic cells are way different from hepatic cells. They don't have the same function, so they need to undergoing a process "to differentiate" themselves, according to their function. "Poorly differentiated", on the other hand, means that tumor cells do no resemble the tissue where they arose from, and that is, of course, not good at all. One last thing. When talking of hepatocellular tumor, you don't need to say "liver", because the prefix hepato means "liver".
Containing an excessive number of blood vessels. Usually referring to a tumor or the liver where there are hepatic abnormalities. See Link for Wilson's disease & hypervascular.
Just that, a CT liver. Technically you could make it hepatic CT imaging.
Morphology (tissue type) and topography (anatomical site).
A hard tumor is not a tumor
Extensive lymphovascular invasion refers to the presence of cancer cells in the lymphatic and blood vessels surrounding a tumor. This indicates an increased risk of cancer spreading to other parts of the body through these vessels. It is an important factor in determining the stage and prognosis of cancer.
Laminectomy is used for metastatic tumor invasion of the spinal cord (which causes compression), and for narrowing of the spinal cord (a condition called spinal stenosis.)
Wilms' tumor is a type of malignant tumor
The presence of lactic acid in the tumor microenvironment can contribute to the progression and development of cancer by promoting tumor growth, invasion, and resistance to treatment. Lactic acid can create an acidic environment that helps cancer cells survive and thrive, as well as promote the formation of new blood vessels to supply nutrients to the tumor. Additionally, lactic acid can suppress the immune system's ability to attack cancer cells, making it harder for the body to fight off the disease.
Lateral invasion is a term used to describe the process by which tumors spread within the body by invading surrounding tissue and organs instead of spreading through the bloodstream or lymphatic system. This method of spread can make it difficult to detect and treat the tumor effectively.
