Sarcoma

    A cancer of the bone, cartilage, fat, muscle, blood vessels or other connective or supportive tissue. A sarcoma is also defined as malignant mesenchymal neoplasm; e.g. osteosarcoma, (malignant mesenchymal neoplasm arising from bone tissue). Malignant tumor of soft tissue (tissue that connects, supports or surrounds other structures and organs of the body). Soft tissue includes muscles, tendons, fibrous tissues, fat, blood vessels and nerves.

RELATED TERMS
--------------------------------------

Cancer
Any malignant growth or tumor caused by abnormal and uncontrolled cell division; it may spread to other parts of the body through the lymphatic system or the blood stream.

Bone
Bone refers either to a hardened connective tissue or to one of the individual structures, or organs, into which it is formed, found in many animals. Bones support body structures, protect internal organs, and (in conjunction with muscles) facilitate movement; are also involved with cell formation, calcium metabolism, and mineral storage. The bones of an animal are, collectively, known as the skeleton.

Cartilage
A firm, flexible connective tissue. In vertebrates, the cartilage forms the skeleton in the early stages of development, after which it is largely replaced by bone. Some cartilage remains at the joints to give flexibility and support.

Fat
A major energy source for animals and humans. Fat contains nine calories per gram.

Muscle
Tissue made up of bundles of long, slender cells that contract when stimulated.

Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.

Tissue
Biological tissue is a group of cells that perform a similar function.The study of tissues is known as histology, or, in connection with disease, histopathology.The classical tools for studying the tissues are the wax block, the tissue stain, and the optical microscope, though developments in electron microscopy, immunofluorescence, and frozen sections have all added to the sum of knowledge in the last couple of decades.

Sarcoma
A cancer of the bone, cartilage, fat, muscle, blood vessels or other connective or supportive tissue. A sarcoma is also defined as malignant mesenchymal neoplasm; e.g. osteosarcoma, (malignant mesenchymal neoplasm arising from bone tissue). Malignant tumor of soft tissue (tissue that connects, supports or surrounds other structures and organs of the body). Soft tissue includes muscles, tendons, fibrous tissues, fat, blood vessels and nerves.

Malignant
Cancerous; life-threatening.

Neoplasm
New and abnormal growth of tissue that may or may not cause cancer. Also called tumor.

Osteosarcoma
Osteosarcoma is the most common primary malignant bone tumour, excluding myeloma and lymphoma. There is a predilection for the metaphyseal region of tubular long bones. 50% of cases occur around the knee. It is a cancer that usually affects the large bones of the arm or leg. It occurs most commonly in young people and affects more males than females. Also called osteogenic sarcoma.

Tumor
Overgrowth of tissue.



SIMILAR TERMS
--------------------------------------

Sarcoidosis
A chronic, systemic, granulomatous disease of unknown origin which may involve almost any body organ or tissue and is characterized by the presence of noncaseating nodules in the covering of the internal/external surfaces of the body.

Sarcoma

Serous membrane
A thin membrane lining the closed cavities of the body; has two layers with a space between that is filled with serous fluid

Serum
The fluid portion of the blood. It is essentially similar in composition to plasma but lacks fibrinogen and other substances that are used in the coagulation (blood clotting) process.

Systolic
Measurement of the maximum blood pressure in the arteries. The larger number is the systolic pressure caused by each pump of the heart.

Semen
The fluid containing sperm (the male reproductive cells) that is expelled (ejaculated) through the end of the penis when the man reaches sexual climax (orgasm).

Sperm
A sperm cell, or spermatozoon (pl. spermatozoa) (in Greek: sperm = semen and zoon = alive), is the haploid cell that is the male gamete. It is carried in fluid called semen, and is capable of fertilising an egg cell to form a zygote. A zygote can grow into a new organism, such as a human. Sperm cells contain half of the genetic information needed to create life. Generally, the sex of the offspring is determined by the sperm, through the chromosomal pair "XX" (for a female) or "XY" (for a male).
