Cancer Diagnosis

Cancer Diagnosis Photo Cancer can be cured if it is diagnoized early. There are several methods of diagnosing cancer. With advances in technologies that understand cancers better, there is a rise of number of diagnostic tools that can help detect cancers. Some types of cancer, particularly lymphomas, can be hard to classify, even for an expert. Most cancers need a second opinion regarding diagnosis before being sure of the diagnosis or stage and type. The most common diagnostic methods include Biopsy is a test where a small amount of sample is taken from the lesions and viewed under microscope for cancer cell. Sentinel node biopsy is same procedure as biopsy only difference is that in this process sample is taken from the nodal part of the body that likely contains cancer cells. Endoscopy is a small flexible tube that is inserted into the suspicious area of the body. The end of the tube contains a camera to view the inner organs. Blood tests are done to detect the tumor markers present in the blood. Some tumors release a substance called tumor markers in the blood. Prostate specific antigen (PSA) can also be detected by blood test Bone marrow aspiration shows the perfect picture of the bone marrow affected with leukemia. Pap test is mainly used in the detection of cervical cancer in woman. Sputum analysis the cells are observed under the microscope to analyze the signs of lung cancer. Bronchial washing analysis the bronchi cells are examined under the microscope to analyze the signs bronchial cancer. Several Imaging techniques are present to diagnose cancer. In Genetic analysis the genes undergo cytogenetic analysis to show up genetic mutations.
