A biopsy is the main way doctors diagnose most types of cancer. Other tests can suggest that cancer is present, but only a biopsy can make a diagnosis. Biopsy confirms the diagnosis of a cancer and is usually the first step to treatment. The site of biopsy depends on how invasive it is and if it can reach all the tumor cells. A cancer biopsy can identify various types of cancer. Traditionally, Cancer Diagnostics relies on pathology and antibody staining. But new technologies are beginning to change the way that doctors diagnose cancer. One such advancement is a genomic test that allows physicians to analyze all the cells of a patient's tumor.
These tests can be included in the pathology report or sent separately. This may lead to a more detailed staging and treatment. However, it is only available for cancer patients who undergo surgery. Imaging tests are an important component of cancer diagnostics. With the help of a microscope, doctors can identify whether cancer cells have spread to other parts of the body. A CT scan, a form of x-ray that uses high-resolution images to visualize the inside of the body, can be used to determine the presence of cancer cells. These tests can be expensive and require multiple sessions. Therefore, it is important to consult a doctor.
