What are the most common diagnostic tests for cancer?
Diagnostic tests for cancer are crucial for early detection and successful treatment. The most common diagnostic tests include:
- Biopsy: This involves removing a small sample of tissue to examine it under a microscope for cancer cells. Different types of biopsies include needle biopsy, incisional biopsy, and excisional biopsy. - Imaging Tests: These tests create images of the inside of the body. Common imaging tests include X-rays, CT scans, MRI scans, ultrasound, and PET scans. - Blood Tests: Some cancers can be detected by measuring specific substances in the blood, such as tumor markers or abnormal levels of certain blood cells. - Endoscopy: This procedure involves using a flexible tube with a light and camera to view the inside of organs and take tissue samples if necessary.
