Mitosis is the process via which cells divide, producing copies of themselves. Cancer is essentially mitosis that is out of control. Cancer cells do not operate in the same way as other cells in the system they occupy, so they replicate and damage surrounding tissues.Know More
When cells divide, the result is generally two identical copies of the original cell. A "parent" cell distributes its genetic material into two "daughter" cells during replication, which then take on the characteristics of the parent cell. Usually, this process works seamlessly; however, when Cell Cycle genes mutate within cells, mitosis goes from a controlled process to an uninhibited, reactive event.
Unlike normal cells, which respond to density-dependent inhibition, tumor cells continue to divide, and multiply at an increased rate until all available nutrient supplies are depleted. When tumor cells are benign, they remain at the original site. When they are malignant, however, the tumor quickly becomes invasive: at this point, the mass is known as cancer.
Sometimes, cancerous tumors contain cells capable of triggering the formation of blood vessels specifically designed to create a nutrient supply for the mass. Malignant cells then gain a pathway via which they can travel to other parts of the body. When this occurs, the tumor has metastasised.Learn more about Cancer
The exact cause of bile duct cancer is unknown, according to Healthline, but scientists implicate mutations in the bile duct cells' DNA. Bile duct cancer is a type of liver cancer that starts in the bile duct cells. The bile duct is a tube that extends from the liver to the small intestines.Full Answer >
Plant cells divide through the process of mitosis, followed by cytokinesis. Mitosis in plant cells is similar to mitosis in animal cells, which occurs in four stages: prophase, metaphase, anaphase and telophase.Full Answer >
Somatic cells go through the process of mitosis. The Genetics Home Reference website defines a somatic cell as any cell that is not an egg cell or sperm cell.Full Answer >
Most cells undergo the process of mitosis for growth and repair. However, some cells, such as neurons and muscle cells, no longer divide upon reaching full development.Full Answer >
