What is Brain Cancer Or Tumors
A researcher, says that two genes, mutations in the region of chromosome 1 and 19 cause cancer in the body. The researchers say that other genetic mutations are the most common form of brain cancer have biological causes of cancer.
They made the sequence of the genes that encode proteins in tissue samples from seven of the tumors and focused on recurrent mutations in 2 genes.
The scientists said that genes are the ?two hit? theory of cancer development is insufficient. There are 23 copies of the chromosomes in the human body to produce thousands of genes, proteins?. Missing in each copy, can lead to protein deficiency, and missing the second copy, which can lead to cancer.
Brain tumor is a brain disorder that causes cancer cells in the brain tissue. Cancer cells grow on a piece of cancer tissue to make it alters brain function and muscle control, memory and other body functions.
Tumors composed of cancer cells and malignant and nonmalignant cells of benign tumors known.
According to the National Brain Tumor Cancer, the Institute may, in about 22,000 new people come each year and about 13,000 deaths from the disease.
Types of Brain Cancer or Tumors
Primary Brain Cancer
Primary Brain Cancer occurs in the Brain.
Metastatic Brain Cancer
This type of Brain Cancer starts in some other part of body then Brain and it finally moves to the Brain.
They may develop at this stage of the cancer cells in the lungs and spread through the blood. Tumors of the cancer cells have spread to other parts of the body is called metastasis of the tumor.
These tumors are usually named for the institution, such as lung cancer or breast cancer tumors.
Brain Cancer Or Tumors ?Stages
Stage 1
At this point, the tissue is benign. These cells are found in brain cells neighborhood, and grow slowly.
Stage 2
The tissue is malignant. The cells resemble normal cells to compare the cells in phase 1 of the tumor.
Stage 3
The malignant cells of tissues, normal cells are very different. The abnormal cells grow quickly and have strange phenomenon.
Stage 4
The fabric of this stage also abnormal phenomenon, and they grow very rapidly in the brain.
Causes of Brain Cancer Or Tumors
Primary brain tumors can arise from different types of brain tissue, such as glial cells, astrocytes, etc.
Metastatic brain cancer is caused by the spread of tumor cells from other parts of the brain. The main causes of these two forms are not yet clear.
The researchers found some of the risk factors for cancer of the brain, which are:
Use of an oil refinery
People with chemicals such as benzene, including chemicals and industrial workers.
Heredity may be a cause of brain tumors in some families.
Smoke
Exposure to radiation
Viral infections
HIV
Brain cancer is not contagious.
There is no evidence that it may be caused by cell phones.
Some studies suggest that brain tumors are caused, may be due to artificial sweeteners.
Symptoms of Brain Cancer Or Tumors
Weakness
Difficulty walking
Seizures
Headaches
Nausea
Vomit
Blurred vision
Difficulty concentrating
Change in mental ability
Amnesia
Loss of speech
Personality changes
Difficulties with balance or walking.
Spasms.
Numbness of the arms or legs.
These symptoms can also occur in people who suffer from this type of cancer. These symptoms can predict not only the disease.
Cancer can occur anywhere in the brain, the brain, including occipital, frontal, parietal, temporal lobe, brain stem or meninges.
Some brain tumors cause few or no symptoms.
Diagnosis of Brain Cancer Or Tumors
The first evidence is the clinical history and physical examination by a doctor.
To sort the results of these things, the need for tests and exams.
The most common test to detect the tumor in the brain is scanned. This test is the same as X-rays and is not painful.
Sometimes a contrast dye into the body for better recognition and images of the internal structure of the brain that is injected.
Another test that is becoming increasingly popular due to its high detection technique, magnetic resonance imaging of the brain. This test is similar to X-ray, but there are better results than CT Scan.
CT Scan is more common than MRI. If the results show the presence of cancerous tissues, such as neurosurgeons and neurologists and other physicians treating the patient.
Sometimes a biopsy is performed to remove tissue samples and then checked in the laboratory to the exact type and stage of cancer research.
Brain Cancer Or Tumor Treatment
Specialists from the brain to the treatment plan for the patient and the treatment varies depending on the type, tumor size, patient age, patient status and location of the cancer.
Surgery
Radiotherapy
Chemotherapy
Hyperthermia
Immunotherapy
The treatment plan can be any combination of these therapies.
Surgery is used to tumor cells by removing them away from normal brain cells.
Operation of the radiation kills cancer cells through interaction with radiation in high definition. That?s not surgical. The radiation can be gamma rays or X-rays
Chemotherapy kills tumor cells through the use of chemicals or drugs that destroy these types of cancer cells.
Hyperthermia is a heat treatment. The type of treatment is immunotherapy, in which immune cells designed to kill cancer cells.
Treatment plans developed by scientists and physicians, designed to prevent the disease is a way to treat the patient.
Side Effects of Brain Cancer Drugs Treatment
Increase the symptoms of this disease.
Brain Injury
Inflammation of the brain
Seizures
Weak
Mental changes
Decreased brain controls.
Nausea, vomiting, hair loss, depression, susceptibility to infection and the energy loss side effects of chemotherapy.
The kidneys and reproductive organs can be damaged by chemotherapy.
The skin is affected by the radiation, red patches appear on different parts of the skin and hair loss can also occur.
Prognosis ?And Prevention of Brain Cancer
The prognosis of brain tumors varies from 10% to 32%. No matter what type of treatment is used. Recovering from a brain tumor is possible, but full recovery is not possible sometimes. About 75% of children survive more than 5 years due to serious illness. Without treatment, brain tumors can kill quickly.
prevention
No specifically for brain cancer, early diagnosis and treatment of tumors may reduce the risk of brain tumors, prevent metastases.
Brain Cancer?is a serious type of cancer If not treated well and on time can lead to death.
