It may be done with other procedures, such as biopsies, to help diagnose some types of cancer. It can also be used to check for certain changes in a gene or chromosome that may increase a person’s risk of developing cancer or other diseases.

Molecular profiling: A laboratory method that uses a sample of tissue, blood, or other body fluid to check for certain genes, proteins, or other molecules that may be a sign of a disease or condition, such as cancer.The test results are based on how the cells that were stained with the fluorescent dye react to the beam of light. The cells from a sample of a patient’s blood, bone marrow, or other tissue are stained with a fluorescent dye, placed in a fluid, and then passed one at a time through a beam of light. Flow cytometry: A laboratory test that measures the number of cells in a sample, the percentage of live cells in a sample, and certain characteristics of the cells, such as size, shape, and the presence of tumor (or other) markers on the cell surface.This type of test is used to help diagnose cancer and to help tell one type of cancer from another type of cancer. After the antibodies bind to a specific antigen in the tissue sample, the enzyme or dye is activated, and the antigen can then be seen under a microscope. The antibodies are usually linked to an enzyme or a fluorescent dye. Immunohistochemistry: A laboratory test that uses antibodies to check for certain antigens ( markers) in a sample of a patient’s tissue.The following tests may be done on the tissue that was removed: High-grade tumors usually grow and spread more quickly than low-grade tumors.īecause soft tissue sarcoma can be hard to diagnose, the tissue samples should be checked by a pathologist who has experience in diagnosing soft tissue sarcoma. The grade of a tumor depends on how abnormal the cancer cells look under a microscope and how quickly the cells are dividing. A pathologist views the tissue under a microscope to look for cancer cells and toįind out the grade of the tumor. Samples will be taken from the primary tumor, lymph nodes, and other suspicious areas. An incisional biopsy may be done when a core needle biopsy is not safe to perform or core needle biopsy findings are not clear.Ĭareful planning of the biopsy should involve the surgeon, a radiation oncologist, and an interventional radiologist who uses medical imaging to guide diagnosis. Incisional biopsy: The removal of part of a lump or a sample of tissue.This procedure may be guided using ultrasound, CT scan, or MRI. Core needle biopsy: The removal of tissue using a wide needle.
