Hello Readers, to update you about the brain tumors diseases, today I am writing about the type of brain tumor and their symptoms, please feel free to comment on articles and ask questions as much as you can. Brain tumors are classified on the basis of signs and symptoms noted in a person who is affected by this disease, doctors termed brain tumors in two categories based on condition of patient one is primary and other is secondary. As we know brain is the central system of our body which has control on all functions of our body, so if our brain is affected by brain tumor disease then it may results into failure movement, coordination, voice, hearing, memory or behavior etc. It is not necessary that every patient have similar type of symptoms in brain tumors it may vary from patient to patient. A ‘Secondary’ or Metastatic tumor is defined as a tumour which has spread distantly from the original or ‘Primary’ cancer site, through the blood circulation, lymphatic system or spinal fluid. This can involve either a single lesion (Metastasis) or multiple tumours (Metastases). Metastases can in theory spread to any point in the body, but for the purposes of Gamma Knife, only brain metastases are suitable for treatment. As they are defined by the spread of tumours from one organ to another, metastases are different from ‘Primary’ brain tumour, which are tumours that start within the tissues of the brain. This is an important factor, as treatment options for Primary and Metastatic Brain tumours are often different. These secondary tumours arise most commonly from primary carcinomas of the lung, breast, kidney, colon and melanomas of the skin, although it is possible for a number of other primary tumours to occasionally spread to the brain. Sex differences play a role with lung, colon and renal cancers accounting for 80% of metastatic brain tumours in men, and breast, lung, colon and melanoma cancers accounting for 80% of metastatic Brain tumor in women. Independent of the Primary disease, successful results can be elicited from Gamma Knife Radiosurgery for metastases from a number of primary tumour sites. Not all patients are suitable for Radiosurgery, as often it requires that there are only a low number of lesions within the head, all of which ideally are below a threshold volume, (as the larger the volume, the more healthy brain tissue will be treated). The location of the lesions within the brain may also play a deciding role in the most suitable treatment method for the patient. An important factor is also that any disease present in the rest of the body should be controlled, i.e. non-active. The effects of your treatment will occur over time. Radiation treatments are designed to stop the growth of tumours or dysfunctional tissue, which means that the effect will be seen over a period of weeks or months. Your doctor will stay in contact with you and you’re referring Consultant to assess your progress. Follow-up imaging such as MRI or CT may be undertaken 3-12 months after treatment.
