Brain Tumor: Causes, Signs and Symptoms
A brain tumor is a collection of abnormal cells inside the brain. The majority of brain tumors are generally benign and develop slowly, but some are malignant and grow rapidly. The most common symptoms include recently started headaches, vomiting, sleep disturbances, nausea, and exhaustion. Several factors determine the treatment plan and outcome including the kind and size of the brain tumor, the location of cancer, and its growth rate. However, the advancement in technologies and surgical techniques have made significant improvements in patient survival and outcomes.
What is Brain Tumor?
A brain tumor is a lump of abnormal cells within the brain. These brain tumors can be further divided into primary and secondary brain tumors. Primary brain tumors are those that develop due to abnormal growth in the brain cells whereas secondary brain tumors develop from other cells of the body. Additionally, all brain tumors can be categorized under benign and malignant brain tumor
Brain Tumor Causes
A brain tumor usually develops when the cells in the brain start growing abnormally in size or number. Normally the process of cell division or cell growth is strictly controlled by the instructions stored in the DNA of the cell. However, sometimes alterations (mutation) in this DNA information lead to abnormal cell activity. This result in the formation of an abnormal lump of cells known as a tumor. Certain risk factors increase the chances of brain tumors. These include
Brain Tumor: Common Signs and symptoms
The overall symptoms of brain tumor may depend on the specific type, growth rate, location, and severity of the tumor. Slow-growing tumors may go undetected until they are large enough to be diagnosed. These tumors can pressure nearby nerves, causing discomfort. Tumors that form in areas crucial for certain activities such as speech, hearing, vision, feeling, and movement will cause deficiencies in those capabilities. Here are some of the common signs and symptoms of brain tumor:
Management of Brain Tumor
With the advancement in technologies, the management of head tumors has also become better. The main therapies used in the management of a head tumor are surgical therapy, radiation therapy, and chemotherapy. Surgery is usually advised when the tumor is located within the brain and has not spread. The overall aim of a surgical treatment revolves around removing as many tumor cells as possible without harming the healthy brain tissue. Radiation therapy is used to restrict the growth of the tumor. Often a combination of either of the therapies is used as the best treatment plan. It is always advisable to consult a healthcare specialist to understand the extent of the disease along with a customized treatment plan based on the specific conditions.
