What Are the Alternatives to Imaging for Cancer Diagnosis?
While imaging is a crucial tool in cancer diagnosis, it is often used in conjunction with other methods:
- Biopsy: A biopsy involves taking a tissue sample from the suspected tumor site for histological examination, providing definitive evidence of cancer. - Blood Tests: Certain blood tests can detect tumor markers or genetic mutations associated with specific cancers. - Endoscopy: This involves using a flexible tube with a camera to visualize internal organs and take tissue samples, useful for cancers of the digestive and respiratory tracts. - Physical Examination: Experienced clinicians can sometimes detect abnormalities through a thorough physical examination.
