|
cells that break off of a tumor and travel in blood vessels but can’t settle anywhere else
|
|
|
they can only grow in the same part of the body where they first started

cancer cells can’t grow and change

Detailed explanation-1: -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.
Detailed explanation-2: -Spread through the bloodstream Cancer cells can go into small blood vessels and then get into the bloodstream. They are called circulating tumour cells (or CTCs). to help diagnose cancer and monitor treatment. The circulating blood sweeps the cancer cells along until they get stuck somewhere.
Detailed explanation-3: -Once a metastasis has developed, it can itself metasta-size, further amplifying the amount of tumor dissemination [1]. The paths of neoplastic spread in the body are tissue spaces, lymph vessels, blood vessels, coelomic cavities, cerebrospinal spaces, and epithelial cavities [4].
