What term describes localized tumor growth has not spread?
Tumors may be benign (not cancer) or malignant (cancer). Benign tumors may grow large but do not spread into, or invade, nearby tissues or other parts of the body.
What term refers to a tumor?
A tumor can be benign (noncancerous) or malignant (cancerous, meaning it can spread to other parts of the body). Also called a nodule or mass.
Which term describe the spread of malignant tumors to a distant location?
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.
What are growths with sessile and pedunculated types?
Polyps grow in two different shapes: flat (sessile) and with a stalk (pedunculated). Sessile polyps are more common than previously thought and harder to detect in colon cancer screening.
What is localized tumor?
Localized—Cancer is limited to the place where it started, with no sign that it has spread. Regional—Cancer has spread to nearby lymph nodes, tissues, or organs. Distant—Cancer has spread to distant parts of the body.
What is tumour localization?
In medicine, describes disease that is limited to a certain part of the body. For example, localized cancer is usually found only in the tissue or organ where it began, and has not spread to nearby lymph nodes or to other parts of the body. Some localized cancers can be completely removed by surgery.
What angiogenesis mean?
Listen to pronunciation. (AN-jee-oh-JEH-neh-sis) Blood vessel formation. Tumor angiogenesis is the growth of new blood vessels that tumors need to grow.
Which word means formation of tumor?
Medical Definition of tumorigenesis : the formation of tumors.
Which term describes malignant tumors?
There are two general types of tumors: benign (non-cancerous) tumors and malignant (cancerous) tumors.
What does mucinous mean?
Mucinous carcinoma is an invasive type of cancer that begins in an internal organ that produces mucin, the primary ingredient of mucus. The abnormal cells inside this type of tumor are floating in the mucin, and the mucin becomes a part of the tumor.
What is carcinoma in situ?
Carcinoma in situ (CIS) is a group of abnormal cells that are found only in the place where they first formed in the body (see left panel). These abnormal cells may become cancer and spread to nearby normal tissue (see right panel).
Is malignant tumor localized?
Malignant tumors have cells that grow uncontrollably and spread locally and/or to distant sites. Malignant tumors are cancerous (ie, they invade other sites).
What causes angiogenesis?
Sprouting angiogenesis is initiated in poorly perfused tissues when oxygen sensing mechanisms detect a level of hypoxia that demands the formation of new blood vessels to satisfy the metabolic requirements of parenchymal cells (Figure 1.4).
How does angiogenesis and tumor growth?
Angiogenesis plays a critical role in the growth of cancer because solid tumors need a blood supply if they are to grow beyond a few millimeters in size. Tumors can actually cause this blood supply to form by giving off chemical signals that stimulate angiogenesis.
What is angiogenesis and metastasis?
Angiogenesis, the recruitment of new blood vessels, is an essential component of the metastatic pathway. These vessels provide the principal route by which tumor cells exit the primary tumor site and enter the circulation.
What suffix means tumor?
The suffix –oma is used to name tumors. The suffix -oma is used in many medical terms, especially in pathology.
What are the 3 types of tumors?
Types of cancerous tumors include:
- Bone tumors (osteosarcoma and chordomas).
- Brain tumors such as glioblastoma and astrocytoma.
- Malignant soft tissue tumors and sarcomas.
- Organ tumors such as lung cancer and pancreatic cancer.
- Ovarian germ cell tumors.
- Skin tumors (such as squamous cell carcinoma).

What does neoplastic mean?
Definition of neoplastic 1 : of, relating to, or constituting a tumor or neoplasia. 2 (after French néoplastique or German neoplastisch) : of or relating to de Stijl.
What is hyperplasia and metaplasia?
Metaplasia is the transformation of a normal tissue into another normal tissue with different structure and functions. Hyperplasia is characterized by an increased number of cells but without modification of tissue organization.
What is a mucinous tumor?
Mucinous tumors are epithelial ovarian tumors that arise from the transformed cells of the coelomic epithelium that look like the cells of the endocervical epithelium (endocervical or müllerian type) or like the epithelium of the intestine (intestinal type).
What is a mucinous neoplasm?
Mucinous neoplasms of the appendix are a complex, diverse group of epithelial neoplasms often causing cystic dilation of the appendix due to accumulation of gelatinous material, morphologically referred to as mucoceles.
What does the medical term in situ mean?
Listen to pronunciation. (in SY-too) In its original place. For example, in carcinoma in situ, abnormal cells are found only in the place where they first formed.
What is hyperplastic growth?
(HY-per-PLAY-zhuh) An increase in the number of cells in an organ or tissue. These cells appear normal under a microscope. They are not cancer, but may become cancer. Enlarge.
What is Tumour localization?
In medicine, describes disease that is limited to a certain part of the body. For example, localized cancer is usually found only in the tissue or organ where it began, and has not spread to nearby lymph nodes or to other parts of the body. Some localized cancers can be completely removed by surgery.
What is the term of angiogenesis?
(AN-jee-oh-JEH-neh-sis) Blood vessel formation. Tumor angiogenesis is the growth of new blood vessels that tumors need to grow. This process is caused by the release of chemicals by the tumor and by host cells near the tumor.
What angiogenesis means?
(AN-jee-oh-JEH-neh-sis) Blood vessel formation. Tumor angiogenesis is the growth of new blood vessels that tumors need to grow.
What is the difference between neovascularization and angiogenesis?
Neovascularization encompasses both angiogenesis and vasculogenesis. Angiogenesis represents the classic paradigm for new vessel growth, as mature, differentiated ECs break free from their basement membrane and migrate as well as proliferate to form sprouts from parental vessels.
What is the difference between vasculogenesis and angiogenesis?
Vasculogenesis is defined as the differentiation of precursor cells (angioblasts) into endothelial cells and the de novo formation of a primitive vascular network, whereas angiogenesis is defined as the growth of new capillaries from pre-existing blood vessels (Risau, 1997).
Which suffix means tumor or abnormal mass?
The suffix -oma means tumor or abnormal mass. Adenomas and myomas are examples of benign tumors. Carcinomas are malignant tumors. The suffix -osis means abnormal condition; -ia means condition; and -al means pertaining to.
What is suffix Osis?
-osis in American English suffix. a suffix occurring in nouns that denote actions, conditions, or states ( hypnosis; leukocytosis; osmosis), esp. disorders or abnormal states ( chlorosis; neurofibromatosis; tuberculosis)
