A brain tumor occurs with the formation of abnormal cell inside the brain. Hence, there are two types of tumors, malignant or cancerous tumors and benign tumors. Almost all types of brain tumors produce symptoms that vary depending on the part of brain involved. Symptoms include headaches, seizures, and problems with vision, vomiting and other mental changes.
Brain cancer is slightly different from brain tumor. Brain cancer is a disease in which the cancer cells grow to form a mass cancer tissue that intervenes with other brain functions such as muscle control, sensation, memory & other body functions. Cancer cells developing from brain tissue are termed as primary brain tumors while tumors that proliferate from other body parts to the brain are termed as metastatic tumors.
Brain cancers are of different types, categorized into grade I, II, III, IV. In Grade I, the tissue is benign and looks like normal brain cells with a slower growth. In Grade II, the tissue is malignant, and the cells look like normal cells than in Grade I.
In Grade III, the malignant tissue has cells that look very different from normal cells. The abnormal cells are actively growing which have a distinctly abnormal appearance. In Grade IV, the malignant tissue has cells that look almost abnormal and often grow quickly. On detection of brain cancer, symptomatic measures are carried such as medical history and physical exam, imaging tests, MRI scans, CT scans, PET scan etc. is carried out. Such tests determine the level of cell damage for further diagnosis.
The market size drivers for the growth of brain cancer diagnostics are expected to propel by technological developments, improvements in diagnostics machines. Additionally, significance in the rise of brain cancer is expected to grow globally in upcoming years. Rise in number of cigarette smokers responsible for brain cancer have contributing to the market size. However, major restraints comprise heavy costs associated with diagnosis, low awareness levels and lesser accessibility. Therefore, the global market size for Brain cancer diagnostics market size is projected to grow at a double-digit CAGR for the forecast period.
On the basis of test type, the global market size for brain cancer diagnostics is segmented as Magnetic Resonance Spectroscopy, PET scan, single photon emission CT scan (SPECT), spinal tap, magnetic resonance imaging (MRI). On the basis of brain cancer type, the global market size for brain cancer diagnostics is segmented as acoustic neuroma, astrocytomas, chordomas, choroid plexus papilloma, craniopharyngiomas, ependymomas, ganglioneuromas, glioblastoma multiforme, gliomas, meningiomas and others.
On the basis of end-user, the global market size for brain cancer diagnostics is segmented as hospitals, cancer diagnostics center and cancer research institutes. On the basis of treatment, the global market for brain cancer diagnostics is segmented as surgeries, radiation therapy, chemotherapy, immunotherapy and targeted therapy. Surgeries are the most commonly used treatment for most brain cancers in which the tumor cells are removed and further diagnosis is recommended. On the basis of geographic segmentation, the global market for cancer diagnostics spans North America, Latin America, Europe, Asia-Pacific, Middle-East & Africa.
North America dominates the global market share owing to the presence of favorable reimbursement policies and advanced healthcare infrastructure. APAC regions are lucrative markets for the growth of brain cancer diagnostics owing to the presence of heavy unmet needs in the emerging economies such as China and Japan. Researchers at University of Illinois have found a way to deal with cancer cells. Researchers have used Graphene to differentiate a single hyperactive cancerous cell from a normal cell simply by interfacing it. The graphene system is capable of detecting the level of activity of interfaced cell. Owing to its characteristics, Graphene is most suitable and a noninvasive tool for early cancer diagnosis. It is thin and is most sensitive to its surface conditions. The key players in the global market for brain cancer diagnostics market include Hologic, Inc., NantOmics, GE Healthcare, Thermo Fisher Scientific, Inc., and Siemens Healthcare Diagnostics.
