  • tumor
  • In many cases, a biopsy can remove the whole tumor, as long as the healthy tissues removed from just outside the tumor area do not contain any cancer cells. (wikipedia.org)
  • Furthermore, core needle biopsy allows more accurate histological typing of the tumor. (wikipedia.org)
  • A similar process is used by radiologists to localize known malignancies that have previously undergone core biopsy so that the tumor can be definitively removed. (wikipedia.org)
  • Finally, a biopsy of the tumor, taken through a needle during a simple surgical procedure, helps to confirm the diagnosis. (wikipedia.org)
  • However, the best choice of treatment will depend on many individual factors, including: The patient's medical history and overall health condition The type, location, and size of the tumor The patient's age How well the patient tolerates specific medications, procedures, or therapy How slowly or quickly the tumor is expected to progress If surgery is performed and the tumor is completely resected, further treatment may not be required. (wikipedia.org)
  • An incisional biopsy or core biopsy samples a portion of the abnormal tissue without attempting to remove the entire lesion or tumor. (wikipedia.org)
  • There are two types of liquid biopsy (which is not really a biopsy as they are blood tests that do not require a biopsy of tissue): circulating tumor cell assays or cell-free circulating tumor DNA tests. (wikipedia.org)
  • By detecting and quantifying genomic alterations in CTCs and cell-free DNA in blood, liquid biopsy can provide real-time information on the stage of tumor progression, treatment effectiveness, and cancer metastasis risk. (wikipedia.org)
  • The tests analyze circulating tumor cells (CTCs) Analysis of individual CTCs demonstrated a high level of heterogeneity seen at the single cell level for both protein expression and protein localization and the CTCs reflected both the primary biopsy and the changes seen in the metastatic sites. (wikipedia.org)
  • lesions
  • A 2003 Cochrane review found screening by breast self-examination is not associated with lower death rates among women who report performing breast self-examination and does, like other breast cancer screening methods, increase harms, in terms of increased numbers of benign lesions identified and an increased number of biopsies performed. (wikipedia.org)
  • renal biopsy

  • In a transplant renal biopsy, the kidney of another person that has been transplanted into the patient is biopsied. (wikipedia.org)
  • Renal biopsy may be performed with the aid of "real-time" medical imaging to guide the positioning of biopsy equipment (imaging-guided renal biopsy). (wikipedia.org)
  • Alternatively, a biopsy may be performed without imaging-guidance using indirect assessments of position such as "needle-swing" to confirm appropriate placement of biopsy equipment (blind renal biopsy). (wikipedia.org)
  • While renal biopsy is not indicated in all cases of haematuria, it may be performed in those with glomerular haematuria (blood that is thought to come from damage to the glomerulus) or when combined with features of progressive renal disease (e.g. increasing proteinuria, elevated blood pressure and kidney failure). (wikipedia.org)
  • Renal biopsy is usually reserved for patients with high or increasing levels of proteinuria, or for patients who have proteinuria along with other signs of renal dysfunction. (wikipedia.org)
  • Transplant kidney biopsy is performed in the following circumstances: For surveillance of hidden disease involving the transplant kidney, so-called protocol renal biopsy undertaken at fixed intervals post-transplantation. (wikipedia.org)
  • The safety of renal biopsy is affected by the following conditions: bleeding diathesis uncontrolled severe high blood pressure uncooperative patient presence of a solitary native kidney azotemia or uraemia certain anatomical abnormalities of the kidney skin infection at the biopsy site medications that interfere with clotting (e.g. warfarin or heparin) pregnancy urinary tract infection obesity Like most invasive medical procedures, a renal biopsy is not without risk (see Complications). (wikipedia.org)
  • A nephrologist will have to satisfy themselves that a renal biopsy is of appropriate benefit to justify the risks of the procedure before proceeding. (wikipedia.org)
  • kidney biopsy
  • Owing to the limited sampling associated with kidney biopsy, however, the findings are unlikely to be sufficiently decisive to enable any organs except those with probably the most florid disease to be discarded. (lifescienceexec.com)
  • Table 1 MAPI assessment of donor kidney biopsy samples Many investigators possess addressed the query of whether gene manifestation profiles in donor biopsy samples might help to assess the quality of the organ. (lifescienceexec.com)
  • Transplant kidney biopsy can be performed when nothing is apparently wrong with the transplant kidney for the purposes of surveillance for hidden disease (protocol transplant biopsy). (wikipedia.org)
  • Kidney biopsy is performed on selected patients with kidney disease. (wikipedia.org)
  • The decision on whether or not to proceed to a kidney biopsy is usually made by a nephrologist. (wikipedia.org)
  • The following are examples of the most common reasons for native kidney biopsy: Haematuria (or blood in the urine) can occur with a number of conditions that affect the kidneys and urinary tract. (wikipedia.org)
  • The cause of acute kidney failure can usually be determined without kidney biopsy. (wikipedia.org)
  • Targeted kidney biopsy can be used to obtain tissue from a tumour arising from or adjacent the kidney. (wikipedia.org)
  • benign
  • Study of these biopsy specimens revealed various benign conditions, such as white pulp hyperplasia, myeloid metaplasia, storage disease, and granulomatous processes and abscesses. (unisa.it)
  • sFNAB was the only diagnostic procedure employed for the morphologic assessment of 60 benign and of 2 malignant cases. (unisa.it)
  • Pathologic examination of a biopsy can determine whether a lesion is benign or malignant, and can help differentiate between different types of cancer. (wikipedia.org)

  • metastatic
  • Others consider the procedure only appropriate for those with other health problems making rest possibly detrimental, those with metastatic cancer as the cause of the spine fracture, or those who do not improve with conservative management. (wikipedia.org)
  • lesion
  • If a pancreatic lesion of concern is identified, a small needle is inserted in the lesion in the pancreas and cells of the lesion are aspirated. (clinicaltrials.gov)
  • Furthermore
  • Furthermore, we describe the way the evaluation of renal allograft biopsy has been improved by innovative methods that could revolutionize the administration of patients who've undergone renal transplantation. (lifescienceexec.com)
  • implantation
  • Biopsy of the transplanted kidney taken during the transplant operation is termed implantation transplant biopsy or post-perfusion transplant biopsy depending on the timing of the biopsy with respect to key stages of the operation. (wikipedia.org)
  • lump
  • This type of sampling is performed for one of two reasons: A biopsy is performed on a lump or a tissue mass when its nature is in question. (wikipedia.org)
  • When the lump can be felt, the biopsy is usually performed by a cytopathologist or a surgeon. (wikipedia.org)
  • incision
  • The needle normally has a lateral ("from the side") opening and can be rotated allowing multiple samples to be collected through a single skin incision. (wikipedia.org)
