Which term describes the spread of a malignant tumor?

Listen to pronunciation. (meh-TAS-tuh-sis) The spread of cancer cells from the place where they first formed to another part of the body.

Which term describes the spread of tumor cells to distant sites?

Metastasis is the general term used to describe the spread of cancer cells from the primary tumor to surrounding tissues and to distant organs and is the primary cause of cancer morbidity and mortality. It is estimated that metastasis is responsible for about 90% of cancer deaths.

What term describes localized tumor growth has not spread?

Benign. Refers to a tumor that is not cancerous. The tumor does not usually invade nearby tissue or spread to other parts of the body.

What is a malignant tumor derived from epithelial tissue?

Carcinoma. Carcinoma refers to a malignant neoplasm of epithelial origin or cancer of the internal or external lining of the body. Carcinomas, malignancies of epithelial tissue, account for 80 to 90 percent of all cancer cases. Epithelial tissue is found throughout the body.

When a tumor is malignant That means it is?

Malignant tumors are cancerous. They develop when cells grow uncontrollably. If the cells continue to grow and spread, the disease can become life threatening. Malignant tumors can grow quickly and spread to other parts of the body in a process called metastasis.

Is a neoplasm a tumor?

When reading about health topics, you might come across the word “neoplasm,” which is actually another word for tumor. A tumor is a mass made up of cells that have divided abnormally. While being diagnosed with a neoplasm or tumor sounds ominous, it’s important to know that not all are cancerous.

What is the grade of a tumor?

Tumor grade is the description of a tumor based on how abnormal the tumor cells and the tumor tissue look under a microscope. It is an indicator of how quickly a tumor is likely to grow and spread.

Is metastasis a death sentence?

Metastatic breast cancer is not an automatic death sentence. Although most people will ultimately die of their disease, some will live for many years.

What type of cancerous tumor is localized?

In medicine, describes disease that is limited to a certain part of the body.

What is the difference between a malignant tumor and a metastasis?

Malignant tumors have cells that grow uncontrollably and spread locally and/or to distant sites. Malignant tumors are cancerous (ie, they invade other sites). They spread to distant sites via the bloodstream or the lymphatic system. This spread is called metastasis.

Is lymphoma a solid tumor?

Solid tumors may be benign (not cancer), or malignant (cancer). Different types of solid tumors are named for the type of cells that form them. Examples of solid tumors are sarcomas, carcinomas, and lymphomas. Leukemias (cancers of the blood) generally do not form solid tumors.

What are five characteristics of malignant tumors?

The malignant cell is characterized by: acceleration of the cell cycle; genomic alterations; invasive growth; increased cell mobility; chemotaxis; changes in the cellular surface; secretion of lytic factors, etc.

What are characteristics of a malignant tumor?

A malignant neoplasm is composed of cells that look less like the normal cell of origin. It has a higher rate of proliferation. It can potentially invade and metastasize. Malignant neoplasms derived from epithelial cells are called carcinomas.
