What is the property of metastasis?
The spread of cancer cells from the place where they first formed to another part of the body. In metastasis, cancer cells break away from the original (primary) tumor, travel through the blood or lymph system, and form a new tumor in other organs or tissues of the body.
What 3 features of cancer cells that allow them to become metastatic?
However in very basic terms, the acquisition of metastasis requires several fundamental steps including (1) loss of cell-cell adhesion, (2) acquisition of motility and (3) the ability to digest through the basement membrane to enter the circulation.
What makes a cell metastatic?
Metastases is the plural form of metastasis. Metastases most commonly develop when cancer cells break away from the main tumor and enter the bloodstream or lymphatic system. These systems carry fluids around the body.
What are the characteristics of a cancer cell What is metastasis?
In metastasis, cancer cells break away from where they first formed (primary cancer), travel through the blood or lymph system, and form new tumors (metastatic tumors) in other parts of the body. The metastatic tumor is the same type of cancer as the primary tumor.
What are the routes of metastasis?
Metastasis occurs by the following four routes:
- Lymphatic spread.
- Hematogenous spread.
- Canalicular spread.
Why are cancer cells invasive and metastatic?
The loss of cell-cell adhesion capacity allows malignant tumor cells to dissociate from the primary tumor mass and changes in cell-matrix interaction enable the cells to invade the surrounding stroma; the process of invasion.
How does metastatic cancer happen?
Metastatic cancer is commonly called stage IV cancer or advanced cancer. It occurs when cancer cells break off from the original tumor, spread through the bloodstream or lymph vessels to another part of the body, and form new tumors. Nearby lymph nodes are the most common place for cancer to metastasize.
What are the steps of metastasis?
Metastatic progression of solid tumors can be divided into five major steps: (1) invasion of the basement membrane and cell migration; (2) intravasation into the surrounding vasculature or lymphatic system; (3) survival in the circulation; (4) extravasation from vasculature to secondary tissue; and finally, (5) …
Does invasion mean metastasis?
For cancer, invasion is the direct extension and penetration by cancer cells into neighboring tissues. It is generally distinguished from metastasis, which is the spread of cancer cells through the circulatory system or the lymphatic system to more distant locations.
