What are the Common Methods for Detecting Cancer Cells?
There are several methods used to detect cancer cells, each with its own advantages and limitations:
Biopsy: A biopsy involves taking a small sample of tissue from the suspected area for examination under a microscope. This is often considered the most definitive way to diagnose cancer. Imaging Tests: Techniques such as MRI, CT scans, and X-rays are used to visualize tumors and assess their size and location. Blood Tests: Certain cancers can be detected through specific markers in the blood, known as tumor markers. These tests are less invasive and can provide valuable information about the presence of cancer. Molecular Testing: This involves analyzing the DNA, RNA, or proteins in cells to detect abnormalities that may indicate cancer. Molecular testing can also provide insights into the genetic mutations driving the cancer.
