Brain Cancer A research says that 2 Gene Mutations in the region of Chromosome 1 and 19 can cause Cancer in the body. Researchers further say that Genetic Mutations are linked with the most common type of Brain Cancer to exhibit the Biological cause of Tumor. They made the sequence of Protein- coding Genes in 7 samples of tissues from Tumor and focused on recurring Mutations in 2 Genes. The scientists said that Genes are missing in the “2 Hit theory” of Cancer development. There are 23 copies of Chromosomes in a human body, which has thousands of Genes that produce Protein. In any copy is missing it can cause deficiency of Protein and if 2nd copy is missing, it can lead to Cancer. What is Brain Cancer? Brain Cancer is a disease of Brain in which Cancer cells are caused in the Brain tissue. Cancer cells grow to make a lump on Cancer tissue; it interferes with the functioning of Brain like muscle control, memory and other body’s function. Tumors consist of Cancer cells also known as Malignant Tumors and non Cancerous cells known as Benign Tumors. According to the National Cancer Institute, Brain Cancer can occur in about 22,000 new people every year and about 13,000 deaths are caused due to this disease. Types of Brain Cancer There are 2 types of Brain Cancer 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. At this stage the Cancer cells develop in Lung and can spread due to Blood. the Tumors made by the Cancer Cells that spread to the other parts of body are known as Metastatic Tumors. These Tumors are mostly named after the name of organ like Lung Cancer Tumors or Breast Cancer Tumors. Stages of Brain Cancer Following are the stages of Brain Cancer Stage 1 At this stage the Tissue is Benign. These Cells are found near Brain Cells and they grow slowly. Stage 2 The tissue is Malignant. The Cells look like normal cells as compare to the Cells in stage 1 of Tumor. Stage 3 The Malignant tissues have cells, which are very different form normal cells. The abnormal cells grow very fast and they have strange appearance. Stage 4 The tissues at this stage also have abnormal appearance and they grow very fast in the Brain. Causes of Brain Cancer Following are the causes of Brain Cancer Primary Brain Tumor can occur from different types of Brain Tissues like Glial Cells, Astrocytes etc. Metastatic Brain Cancer is caused by the spread of Tumor Cells from other parts to the Brain. The main causes of both the forms are still not clear. The researchers found few risk factors for the Brain Cancer, which are as follows: Job in an Oil refinery People dealing with chemicals like Benzene including Chemists and Industry workers. Heredity can be a cause of Brain Cancer for some families. Smoking Exposure to radiations Viral Infections HIV Brain Cancer is not contagious. There are no evidences that it can be caused due to the Cell phones. Some researches claim that Brain Cancer can be caused due to the artificial sweeteners. Symptoms of Brain Cancer Following are the symptoms of Brain Cancer Weakness Difficulty in walking Seizures Headaches Nausea Vomiting Blurry vision Difficulty in concentration Change in Mental ability Loss of memory Loss of speech Change in personality Problems in Balancing or walking. Muscle jerking. Numbness in arms or legs. These symptoms can also occur in the people, who are not suffering from this Cancer. These symptoms can not just predict this disease. Cancer can occur in any part of the Brain of Brain including Occipital, Frontal, Parietal, Temporal Lobes, Brainstem or Meningeal Membranes. Prevention of Brain Cancer There is no specific way to prevent the Brain Cancer, Early diagnosis and the treatment of tumors can reduce the risk of Metastatic Brain Tumors. Brain Cancer is 1 of the severe type of Cancers. If not treated well or in time, it can lead to death.
