Tumor There are two types of tumors: malignant (ma-LIG-nant), or cancerous, tumors are made up of abnormally shaped cells that grow quickly, invade nearby healthy tissues, and often make their way into the bloodstream. When these cells travel to other parts of the body, they form additional tumors.

Bladder Cancer As a result, a mass of extra tissue called a tumor may develop. A tumor can be benign (not cancerous) or malignant (cancerous). Cells in malignant tumors are abnormal and divide without control or order. These cancerous cells can invade and damage nearby tissue, and spread to other parts of the body (metastasize).

Sarcoma A sarcoma (from the Greek σάρξ sarx meaning flesh) is a cancer that arises from transformed cells of mesenchymal origin. Thus, malignant tumors made of cancellous bone, cartilage, fat, muscle, vascular, or hematopoietic tissues are, by definition, considered sarcomas. This is in contrast to a malignant tumor originating from epithelial cells, which are termed carcinoma.

Medical Definition of Tumor There are dozens of different types of tumors. Their names usually reflect the kind of tissue they arise in, and may also tell you something about their shape or how they grow. For example, a medulloblastoma is a tumor that arises from embryonic cells (a blastoma) in the inner part of the brain (the medulla).

Sarcoma A sarcoma (from the Greek σάρξ sarx meaning flesh) is a cancer that arises from transformed cells of mesenchymal origin. Thus, malignant tumors made of cancellous bone, cartilage, fat, muscle, vascular, or hematopoietic tissues are, by definition, considered sarcomas. This is in contrast to a malignant tumor originating from epithelial cells, which are termed carcinoma. Human sarcomas are quite rare. Common malignancies, such as breast, colon, and lung cancer, are almost always carcinoma.

What is the difference between lesion and tumor? Tumors: Benign, Premalignant and Malignant. A tumor, also known as a neoplasm, is an abnormal mass of tissue which may be solid or fluid-filled. A tumor does not mean cancer - tumors can be benign (not cancerous), pre-malignant (pre-cancerous), or malignant (cancerous). There are many different types of tumors and a variety of names for them - their names usually reflect their shape and the kind of tissue they appear in.

Sarcoma (Bone and Connective Tissue Cancer) Program They include tumors that develop in bone, muscle, tendons, nerves, blood vessels and fat. This is in contrast to the more common types of tumors known as carcinomas, which occur in tissues with glands. Bone and connective tissue tumors, also called musculoskeletal tumors, can also be benign.his is in contrast to the more common types of tumors known as carcinomas, which occur in tissues with glands. Bone and connective tissue tumors, also called musculoskeletal tumors, can also be benign.

brain tumor A brain tumor is a collection (or mass) of abnormal cells in the brain. The skull is very rigid and the brain is enclosed, so any growth inside such a restricted space can cause problems. Brain tumors can be cancerous (malignant) or non-cancerous (benign). When benign or malignant tumors grow they can cause the pressure inside the skull to increase. This can cause brain damage and even death.

Brain Cancer The brain is made up of many different types of cells. 1  Some brain cancers occur when one type of cell transforms from its normal characteristics. 2  Once transformed, the cells grow and multiply in abnormal ways. 3  As these abnormal cells grow, they become a mass, or tumor.etastatic brain tumors are made of cancerous cells from a tumor elsewhere in the body. The cells spread to the brain from another tumor in a process called metastasis. This is the most common type of brain tumor.

sarcoma soft tissue sarcoma a general term for a malignant tumor derived from extraskeletal connective tissue, including fibrous, fat, smooth muscle, nerve, vascular, histiocytic, and synovial tissue, with almost all lesions arising from primitive mesoderm.spindle cell sarcoma. 1. any sarcoma composed of spindle-shaped cells.arcoma. a tumor, often highly malignant, composed of cells derived from connective tissue such as bone and cartilage, muscle, blood vessel or lymphoid tissue. These tumors usually develop rapidly and metastasize through the lymph vessels.

Sarcoma A sarcoma is a rare kind of cancer. Sarcomas are different from the much more common carcinomas because they happen in a different kind of tissue. Sarcomas grow in connective tissue -- cells that connect or support other kinds of tissue in your body. These tumors are most common in the bones, muscles, tendons, cartilage, nerves, fat, and blood vessels of your arms and legs, but they can happen anywhere.

What Are Pituitary Tumors? Most pituitary tumors begin in the larger, front part of the pituitary gland known as the anterior pituitary. This part of the gland makes several hormones that control other endocrine glands. 1  Growth hormone (GH, also known as somatotropin) promotes body growth during childhood.2  If too much is made in a child they will grow very tall.his part of the gland makes several hormones that control other endocrine glands. 1  Growth hormone (GH, also known as somatotropin) promotes body growth during childhood. 2  If too much is made in a child they will grow very tall.

Tumor Markers Tumor markers are substances that are produced by cancer or by other cells of the body in response to cancer or certain benign (noncancerous) conditions. Most tumor markers are made by normal cells as well as by cancer cells; however, they are produced at much higher levels in cancerous conditions. These substances can be found in the blood, urine, stool, tumor tissue, or other tissues or bodily fluids of some patients with cancer. Most tumor markers are proteins. However, more recently, patterns of gene expression and changes to DNA have also begun to be used as tumor markers.

- A tumor is a mass of abnormal tissue. There are two types of breast cancer tumors: those that are non-cancerous, or ‘benign’, and those that are cancerous, which are ‘malignant’. When a tumor is diagnosed as benign, doctors will usually leave it alone rather than remove it.

- An epidermoid tumor is a rare, benign neoplasm of the brain. It is congenital and is formed by skin cells that are in the wrong place during fetal development. It consists of an outer covering (the capsule part of it) and an inner mixture of skin cells, and fatty acids.he brain is not invaded by the tumor, but the tumor pushes the brain as it enlarges. The slowly enlarging tumor protrudes from the internal auditory canal into an area behind the temporal bone called the cerebellopontine angle. The tumor now assumes a pear shape with the small end in the internal auditory canal.

Benign Tumors Adenomas are benign tumors starting in the epithelial tissue of a gland or gland-like structure. The epithelial tissue is the thin layer of tissue covering organs, glands, and other structures. A common type of adenoma is a polyp in the colon.n this article. A tumor is an abnormal growth of cells that serves no purpose. A benign tumor is not a malignant tumor, which is cancer. It does not invade nearby tissue or spread to other parts of the body the way cancer can.
