 DESCRIPTION
- Cancerous Metástasis,
- dissemination of the cancer,
- cancer metastático.
DEFINITION
The metástasis are the appearance of a cancerous tumor over a distance of the original in other textiles that has been spread across the blood stream or the lymphatic system.
Not all the cancers are the same way aggressive as for doing or sending metástasis, this depends on the origin, type of cancer, and of his evolution time.
LOCATION OF THE METÁSTASIS
The routes of dissemination and location metastásicas can be:
- lung.
- liver.
- lung and liver.
- vertebral venous plexus (bony).
- lung, liver and vertebral venous plexus (bony).
30 % of the neoplasias of the whole organism gives metástasis to the lung and in half of the cases these compromise only this organ. This high frequency assumed to the fact that the lung receives the whole venous blood originated from all the rest organs. Nevertheless today it is known that it is not sufficient that a tumor cell comes to an organ, but his establishment depends on the existence of recipients and suitable biochemical conditions for her.
SYMPTOMS
The bony metástasis are very painful and they tend to give spontaneous bony breaks.
The hepatic metástasis it can study asymptomatic or giving symptoms of hepatic colics with abdominal pain.
The symptoms and signs of the pulmonary metástasis are variable, depending on his location and extension. They are usually slightly symptomatic, predominating over the proper symptoms of the primary illness. When there is bronchial commitment, the symptoms are indistinguishable of those of a neoplasia or primary pulmonary tumor.
DIAGNOSIS OF METÁSTASIS
- There is carried out usually an analytical general in whom an anemia or the high calcium can appear.
- Analytical other one there are the tumor scoreboards like the CA-125, PSA, CEA or ß2-microglobulina.
- Bony Gammagrafía, that by means of a radioactive scoreboard the cells of pronounced metástasis appear, since more activity and favorite have this scoreboard.
- The Magnetic Resonance and the TAC or Scanner, which are indicated in certain cases.
- The biopsy of suspicious injuries.
- The Scanner for Emission of Positrons (PET in English) is not invasive skill of diagnosis that allows to realize images that show the metabolism and the functioning of textiles and organs, she is very sophisticated and only indicated in some cases by profitability index.
TREATMENT
The treatment of the metástasis depends on the type of original cancer and where it has done metástasis (Lung, liver, spine, etc...)
