Information about the Sarcoma
What is Sacroma?
It is a malignant tumor, and is part of a group of diseases called cancer.
What is a tumor?
A tumor is an accumulation of cells, regardless of whether their activity is benign or malignant.
A benign or malignant tumor?
A benign tumor cell growth is not possessed by the malignancy of cancerous tumors. This implies that this type of tumor does not grow disproportionately and aggressive, does not invade surrounding tissues and metastasize to distant tissues or organs. Benign tumors are not usually life threatening.
Malignant tumors constitute a threat to life, grow disproportionately and aggressively invading nearby tissue and distant organs or tissues (metastasis).
From the embryo…
A cell is the morphological and functional unit of all living things, a set of similar cells form a tissue.
In the first moments of embryo growth, three distinct layers of cells are formed, called, ectoderm, endoderm and mesoderm. The ectoderm is the origin of the skin and nervous system, digestive endoderm, and mesoderm tissue, such as bone, cartilage, fat, muscle, blood vessels, or other.
Sarcomas derive from those cells which form either bone, cartilage, fat, muscle, blood vessels or other during embryonic mesoderm formation.
A sarcoma is a cancer in the form of malignant tumor whose cells have their origin in the embryonic mesoderm.
How many types of sarcoma exist?
There are over 150 varieties of sarcomas recognized by the World Health Organization..
They are divided into two groups, those born in the skeleton and those who do it elsewhere, known as soft tissue sarcomas (SPBS). Ewing’s sarcoma (a type of bone sarcoma) and gastrointestinal stromal tumors or GIST (a type of SPBS) are so unique in all its aspects that they are always considered separately.
There are SPBS whose cells have not been studied in depth, they are called “unknown soft tissue sarcomas .” Of with known, some of the most common types are: liposarcomas, rhabdomyosarcomas, fibrosarcomas, synovial sarcomas, leiomyosarcomas, angiosarcomas, linfagiosarcomas …
The skeletal sarcomas originate in the bone itself. There are three main varieties: osteosarcoma (bone tissue derived), chondrosarcoma (of cartilage), and fibrosarcoma (from fibrous component of the bones)but there are other varieties and subvarieties even more rare. Osteosarcoma is the most common skeletal sarcoma.
What is the prevalence of sarcoma??
– About 1% of the cancers detected are sarcoma
– They constitute the 15-20% of cancers detected in children.
How are sarcomas treated?
– When possible, patients are operated to remove the tumor.
– Radiation therapy and medical treatments like chemotherapy or modern treatments of molecular type can be used to facilitate the operation or to reduce the chance of relapse.
Why is it dangerous?
– It is a difficult cancer to diagnose because in its early stages it can pass relatively unnoticed and it’s sometimes misdiagnosed as a sport injurie.
– When diagnosed, they are usually in a evolved state and have usually metastasized, reducing the possibility of a surgical procedure.
– Many sarcomas are resistant to currently used treatments.
Is it hereditary?
Except for rare exceptions, these cancers are not inherited. In most cases the sarcoma develops in people without known risk factors, so that at present there is no known way to prevent them. Roulette Psychologie – Casino Spiele
