Latest Advances in Diagnosis of Cancer
The risk factors of cancer can be reduced and people’s chances for being well improved by prevention, if cancer is detected on early stages.
In the majority of cases early detection is impossible. Researches are being conducted on different aspects of cancer in order to get some answers and tools for the treatment and diagnosis.
Cancer suffering children often develops anemia because of chemotherapy. Chemotherapy suppresses red blood cells. Now researchers have found out that these children can benefit from a weekly dose of erythropoietin, or EPO. Erythropoietin stimulates the production of hemoglobin in red blood cells.
Recent research in the University of Florida report creating molecular tools that can detect unique molecular fingerprints of cancer tissue. These molecular tools are in the form of aptamers, or short strands of chemically synthesized DNA. This can show the differences caused on the cells to determine whether the cells are cancerous or not. This technique successfully separates leukemia cells from normal bone marrow cells and also differentiates between leukemia T-cells and lymphoma B-cells.
Researchers for the University of Pittsburgh Medical Center have developed Synchrony. Synchrony is able to find out targets and tell the CyberKnife’s robotic arm how to move and when to move. CyberKnife produce accurate amount of radiation dose that can treat lung cancer in one to three session which last between 60 to 90 minutes.
Some of the techniques available for the detection of oral cancer are cytodiagnosis, Vizilite, toluidine blue and the VELscope which can be used only for alleviation of symptoms; however, they cannot be used as biopsy replacement. Oral cancer can be detected with the help of a computer assisted brush biopsy, Oral CDx. This can identify the dangerous precancerous or malignant cells in the form of common oral white or red lesions or ulcerations. This specifically designed brush can capture thousands of cells by a mild surface brush twisting at the suspicious area. These cells are mounted on a microscope slide and scanned through microscope. After scanning through the microscope, the observed morphology of the cell can be reported as normal or positive.
Breast cancer is another major malignancy. Latest surgical technologies for breast cancer are lumpectomy with a sentinel node biopsy and skin-sparing mastectomy.
Another latest advancement in lung cancer is bronchoscopy which is useful for the diagnosis, staging and management of lung cancer. Other newer technologies are auto fluorescence bronchoscopy, narrow band imaging, endoscopic ultrasound, endobronchial ultrasound, electromagnetic navigation, confocal fluorescent laser microscopy and optical coherence tomography.
The latest advancements of kidney cancer diagnosis are physical examination, ultrasonic examination, blood and urine tests, rontgenography, venacavography, radionuclide scintigraphy, computer-aided tomography etc.
Another advancement is the development of drugs which can starve cancer cells. Some other newly introduced drugs find out the cancer cells and attack them and also inhibit the growth of new blood vessels that feed cells.
Advances are also made in radiation therapy. A new technique, radio surgery is developed for therapy of cancer cells to avoid any harmful effect on adjacent and healthy tissues.
With these latest advancements in drugs and technologies, we can hope for a bright future.
