Brain Cancer Disease
The words Brain cancer are enough to strike fear into the heart of anyone. In the United States, about 100000 cases of secondary brain cancer are diagnosed each year, At least 18000 new cases of brain cancer are diagnosed each year . The cause(s) of brain cancer are unknown at present, studies have implicated occupational, environmental, viral, and genetic factors. Compared to other cancers, the rates for leukaemia and brain cancer are relatively low in the Canadian population.
Many of research taken as action to investigate whether the risks of mortality from brain cancer are related to occupational exposure to magnetic fields. Allegations that handheld cellular phone use can cause brain cancer are based on the close proximity of the antenna (from receiver to the user's head), according to the JAMA researchers. Another news is fears that mobile phones may increase the risk of brain cancer are unfounded, according to American researchers. Elevated risks of brain cancer are suspected to be due to maternal smoking (Filippini et al 1994). The main think is we should remember that the chemicals from fertilizers are tracked into the home, where the rates of childhood leukemia, asthma, and brain cancer are higher.
There are two different forms of brain cancer which detected in the human beings, primary brain cancer and secondary secondary brain cancer. The types of primary brain cancer are classified according to the cells which they originate from. Most secondary brain cancer are inoperable. About 15 to 25 percent of all primary brain cancer are meningiomas. Both of brain tumors and brain cancer are an "underground" illness. Brain tumor is a group of benign or malignant disease occurs in the brain. The most aggressive forms of brain cancer are called high grade, lesser degrees of aggressiveness are referred to as low grade.
The common symptoms of brain cancer are headache, seizure and change in mental state, You can say that those are the big three. Beyond the physical effects of the disease, brain cancer brings psychological challenges. Symptoms of brain cancer are caused by damage to vital tissue and by pressure on the brain as the tumor grows within the limited space in the skull. During the course of the disease, many patients with advanced brain cancer may experience some level of pain. Breast cancer, colon cancer, lung cancer, and brain cancer are often misdiagnosed by family physicians or internists.
Research and treatment for brain cancer are far from adequate today. The present treatments for brain cancer are not curative. The most common treatments for brain cancer are radiation therapy, chemotherapy and surgery. Cancer chemotherapeutics for treatment of brain cancer are limited. Current treatment options for primary brain cancer are limited and often present challenges in delivering the drug to its target. Currently, only detachment of the retina and certain types of brain cancer are treated with laser beams.
