Question

When a cancer has undergone _________ that means it has cells that detached from the tumor and traveled to other places in the body through the circulatory system to establish more tumors.

Answer 1

Metastasis occurs when cancer cells break away from the primary tumor, travel through the bloodstream, and form new tumors called metastases in distant sites, leading to a worse prognosis.

Step-by-step explanation:

When a cancer has undergone metastasis, it means that cells have detached from the primary tumor and traveled to other places in the body through the circulatory system to establish more tumors, known as metastases. This process of cancer cells breaking away and entering the bloodstream to be carried throughout the body is a common way that cancer spreads from one part to another.

Once metastasized, the cancer is much harder to control and is often associated with a worse prognosis. These new tumors can form in common places like the brain, lungs, liver, and bones, depending on the type of cancer.

Answer 2

Cancer undergoes metastasis when cells from a primary tumor travel through the bloodstream to form new tumors in different parts of the body, creating metastases. This process is a significant concern in cancer treatment since it complicates stopping or controlling the disease's progression.

Step-by-step explanation:

When a cancer has undergone metastasis, it means that cells have detached from the original tumor and traveled to other places in the body through the circulatory system to establish more tumors. During the process of metastasis, the cancer cells may enter the bloodstream and can be carried throughout the body, where they may start growing in other tissues. This is a critical and concerning phase of cancer progression because it makes the condition very hard to stop or control.

Metastases are the new tumors that form when cancer cells spread from the primary tumor site to distant sites in the body. Certain types of cancers tend to metastasize to particular organs such as the brain, lungs, bones, and liver.

A hallmark of malignant tumors is their ability to grow beyond the boundaries of the tumor itself and spread throughout the body. The blood can carry cancer cells to tissues everywhere in the body, but they generally grow only in certain sites.
