Noticing brain cancer symptoms survival rates for brain tumor depends on various factors, such as the location of the tumor in the brain, the size and type of tumor and stage of the tumor, accordingly proper treatments is important.
Brain cancer develops from cells or tumors within the brain. Part of the central nervous system, the brain is the control center for vital functions of the body, including speech, movement, thoughts, feelings, memory, vision, hearing and more. Brain tumor is basically characterized by the abnormal or uncontrolled growth of cells in the brain. Some of the tumors are noncancerous while some others are cancerous or malignant. The threat to human beings is mostly from the malignant tumors. The tumors occur in the brain in two different ways – some tumors spread from a cancer affected part of the body to the brain, while some other tumors start their growth in the brain itself. Survival rates are low as compared to those of other types of cancers and hence timely detection of tumor and proper treatments is important.
Symptoms of Brain cancer
Brain tumours cause symptoms for two reasons. Firstly, because they take up space inside the skull as they grow. Secondly, they can cause specific symptoms due to their position in the brain. There is more information below about the symptoms due to brain tumours taking up space and symptoms due to the position of the tumour. The most common symptoms of brain tumours that people first go to the doctor with are headaches and fits (seizures). But do remember that brain tumours are rare and there are much more common reasons for both these symptoms. So if you have either of these, do go to the doctor as soon as possible. But remember that there is most likely another cause of the symptoms.
Astrocytic Brain tumours Survival Rate in UK
The survival rates for brain tumor depends on various factors, such as the location of the tumor in the brain, the size and type of tumor, stage of the tumor and whether the patient is suffering from any other ailment. The survival rate is expressed in the form of percentage of people who survive for five years after the diagnosis of the tumor. Astrocytic brain tumours are the commonest type of cancer of the brain. They originate in a particular kind of glial cells, star-shaped brain cells in the cerebrum called astrocytes. This type of tumor does not usually spread outside the brain and spinal cord and it does not usually affect other organs. Astrocytomas can occur in most parts of the brain. Astrocytic tumours include a range of histological types and malignancy grades. The least aggressive WHO grade I tumours are Pilocytic Astrocytomas and Subependymal Giant Cell Astrocytomas. The WHO grade II tumours include Pilomyxoid Astrocytoma, Pleomorphic Xanthoastrocytoma, as well as the Diffuse Astrocytomas, which include the following subtypes – Fibrillary, Gemistocytic and Protoplasmic. Anaplastic Astrocytomas are more aggressive and are WHO grade III.
The most aggressive Astrocytic tumour is Glioblastoma, which is WHO grade IV. It is difficult to estimate incidence of specific types of Astrocytic tumours due to variable precision in the historic registration and coding of brain and CNS tumour types, but Astrocytomas make up over 80% of brain tumours and around 75% of Astrocytomas are highly aggressive Glioblastomas. Astrocytomas can be diagnosed at any age, but the WHO grade I types are more often found in children or young adults, while the WHO grade III and IV types are more prevalent in adults.
Brain, other CNS and Intracranial Tumours Survival Statistics
One-, five- and ten-year survival statistics for brain cancer by age and trends over time are presented here. The ICD code for brain cancer is ICD-10 C71. This is different to the incidence and mortality stats which include other brain cancer codes and non-malignant brain tumours. The statistics on these pages give an overall picture of survival. Unless otherwise stated, the statistics include all adults diagnosed with brain cancer, at all ages, stages and co-morbidities. The survival time experienced by an individual patient may be much higher or lower, depending on specific patient and tumour characteristics.
