What allows cancer cells to become metastatic?
Fluid from the areas surrounding the lymph nodes drains into the lymph nodes. Cells from Tumor cells may break away from the primary tumor and be carried to a nearby lymph node. The lymphatic system is a primary mechanism for tumors to move, or metastasize, to other parts of the body.
What are some requirements for metastasis?
Metastasis is a multi-step process encompassing the (i) local infiltration of tumor cells into the adjacent tissue, (ii) transendothelial migration of cancer cells into vessels known as intravasation, (iii) survival in the circulatory system, (iv) extravasation and (v) subsequent proliferation in competent organs …
What triggers metastasis?
Summary: Cancer metastasis, the migration of cells from a primary tumor to form distant tumors in the body, can be triggered by a chronic leakage of DNA within tumor cells, according to new research.

What is the difference between invasion and metastasis?
Tissue invasion is the mechanism by which tumor cells expand into nearby environments. Metastasis refers to the process of tumor cells breaking away from the primary tumor, migrating to a new location and establishing a new, or secondary tumor, in the new environment.
