The
liver is responsible for the continuous blood flow in the body of
liquidation, as the transfer of nutrients and drugs that are absorbed in
the digestive tract to chemicals ready for use. For the liver and other
important functions, including getting rid of toxins from the blood and
other chemical materials and turn them into secretions. Easy access to
the cancer cells to the liver, as each flowing blood in the body passes
through it.
It
is possible that the first infected liver cancer (Primary cancer),
which consists of himself, or consists cancer elsewhere in the body and
then travels to the liver. In most cases, liver cancer is a secondary or
Nquilia (Relocated cancer - Metastasis cancer), meaning that the source
of the cancerous tumor is present elsewhere in the body.
In
different parts of the world, the first infects the liver cancer in men
affects women twice as much, which is the most common cancer among men,
and mostly affects people over the age of 50 years.
Liver
consists of several types of cells, so there are several tumors could
endure. Be part of the benign tumors (Benign tumor) while the other
malignant tumors (Malignant tumor) {cancerous - Cancerous}, it is
possible that the transmitted / spread to other places in the body.
Different tumors develop for different reasons and it is processed in
different ways. And relate to the prospects for recovery of the tumor
type.
Benign liver tumors, the most common are:
- Hemangioma (Hemangioma)
- Adenoma / Do tumor (Adenoma) in the liver
- Focal tumor-like process
- Cyst (Cyst)
- Leiomyoma (Leiomyoma)
- Lymphoma / lymphoma (Lymphoma)
- Levy / to Efum (Fibroma tumor)
Treatment
of these tumors for treatment of tumors vary. Sometimes, when it may
cause aches or bleeding, there is a need to be surgically eradicated.
Types of liver cancer are:
- Hepatocellular carcinoma (Hepatocellular carcinoma)
- Cancer in the channels of the gallbladder (the source of this cancer is the channel bitterness, we will not go to him in this context).
The causes and risk factors for liver cancer
Primary
liver cancer (hepatocellular carcinoma - Hepatocellular carcinoma) -
affects, usually, people who suffer from congenital abnormalities in the
liver, people who overindulge in drinking alcohol, or people with
pollution chronic, stems from diseases such as jaundice (Jaundice) of
type B and C , hemochromatosis (Hemochromatosis - excess iron in the
liver), as well as cirrhosis (Cirrhosis).
More
than 50% of people with primary liver cancer are infected, too,
cirrhosis (scar in the liver, caused by usually drink excessive alcohol,
jaundice B and C and hemochromatosis, disease can cause N harm to
reverse and failure of the liver).
People
with the genetic disease hemochromatosis, which is reflected in the
lack of large amounts of iron, are exposed significantly to liver
cancer.
Many
carcinogens are considered a major cause of primary liver cancer,
including some herbicides and some chemicals such as polyvinyl chloride
(vinyl chloride) and arsenic (Arsenic). More than smoking, especially
when combined with drinking excessive amounts of alcohol, the risk of
this disease be. Alpha toxin may lead - carcinogenic toxin, produced by a
particular type of mold (fungi) - also to the emergence of this
disease. Alpha resides sometimes toxin in wheat, peanuts, rice, corn and
soybeans.
Other risk factors:
- The sex of the patient
- weight
- The use of anabolic steroids (steroids for body building - Anabolic steroids)
The diagnosis of liver cancer
It
is taken for tests Imaging scans are sweeping all patients for early
detection of primary liver cancer, but it is possible to examine the
possibility of conducting such tests for people most at risk, highly. In
spite of this, the research has not been able to determine whether
imaging scans appropriate and efficient for all patients. For the
diagnosis of liver cancer, it should first deny (exclude) the presence
of other diseases may have the same symptoms.
Highly vulnerable people at risk of contracting the disease are addicted to alcohol and people with chronic jaundice.
Additional tests:
- Blood tests: These tests measure tumor indicators (tags) - materials level rises in the blood when the liver cancer disease, could help determine the diagnosis. Secreted liver cancer substance called alpha fetoprotein (AFP, α - fetoprotein - alpha fetal protein), which are generally the embryos disappear and the time of birth.
- Screening ultrasound imaging (Ultrasound): is the first examination, which is to take place in general, and because it can be detected, whereby, for tumors the size of 1 cm.
- Computed tomography (CT - Computed tmography) and magnetic resonance imaging (MRI - Magnetic resonance imaging): It is possible to reveal these Alvhassan tumors exist and help in the classification and grading, but they Aattiyan in many cases false positive results.
- Biopsy (Biopsy): is the only test able to distinguish between benign tumor and another malignant (cancerous).
- Laparoscopy (Laparoscopy): is an effective screening to detect small tumors, and to determine the perimeter of fibrosis in the liver, or in order to take the biopsy sample (Biopsy) and so on.
- Laparoscopy or sonograms (ultrasound scan) during surgery.
Treatment of liver cancer
All
kinds of liver cancer are among the diseases that are difficult to deal
with them. In a few cases, the initial discovery of liver cancer at an
early stage - the stage be treated good opportunities. Well, difficult
to address the secondary liver cancer or metastases (Metastases) last
cancer had spread to the liver and moved, because cancer in this case
have spread and outbreak.
Moreover,
the complex networks of blood vessels and channels in the liver gall
bladder surgery are difficult to process. Treatment of liver cancer is
based on improving the patient's feeling and try to prolong his life.
You
can remove tumors that were discovered in the initial stages, by
surgery. And the patients who are discovered to have a tumor in the
initial stages of the owners of the biggest chances of recovery.
Regrettably, in most cases of liver cancer can not surgery, either
because the cancer has become in an advanced stage, and either because
the injury is very serious, which inhibits its ability to withstand the
surgery.
In certain cases, can shrink tumors by chemotherapy (Chemotherapy), which can be removed, then, by surgery.
It
is possible to do this same process, sometimes, by ethanol (Ethanol),
instead of chemical processing. Evidence that chemotherapy following
surgery to increase the chances of survival of the patient is not
available. Patients who successfully treated the disease have retreated
into a state Gp, they should remain under surveillance and follow-up
Alchiqtin, so to make sure no recurrence.
- Cryotherapy treatment (Cryotherapy): method of treatment during which freeze the tumor, and the bag by energy radio waves (RFA) in order to annihilate the tumor, a method can be used in certain cases of liver cancer.
- Radiation therapy (Radiotherapy) - These treatments can be performed in several ways, but it has limitations, and that due to the low liver's ability to withstand radiation. Radiation is used to relieve symptoms outside the liver, or to ease the pain in the liver, by reducing the tumor. By Asmam in treatment (Embolization), is the use of chemical treatment or radiation therapy, to stop the blood supply of the tumor. This method can be used to treat large tumors.
- Liver Transplantation: Mahfouz is an option for the treatment of patients suffering from liver cancer and cirrhosis together. There is a great risk in this process, but also the opportunities for healing.
Advanced
liver cancer include the use of one treatment center is. It can
sometimes stop the spread of cancer and alleviate aches, by the use of
chemotherapy and radiotherapy in low doses. But nevertheless, the
efficacy of this type of treatments for this cancer is low.
Most
patients get a combination of painkillers aches powerful drugs to
relieve nausea, bloating, or to improve the appetite. Drug sorafenib
(Sorafenib) is the first to achieve a very significant improvement in
the overall situation for patients with advanced liver cancer, and can
not be treated by chemical treatment.
People
with advanced liver cancer can choose to join a clinical research to
examine the modern therapeutic methods. This research includes the
freezing of tumor cells in order to destroy it, the use of agents
biologists (Biological agents), such as interferon (Interferon) or
interleukin-2 (Interlokin 2) in order to stimulate the immune system to
attack cancer cells, by the use of artificial proteins specially
prepared for destruction of certain tumors.
