Early stage cancer diagnosis typically involves a combination of methods:
- Screening Tests: These are routine tests conducted to detect cancer before symptoms appear. Examples include mammograms, Pap smears, and colonoscopies. - Imaging Tests: Techniques like X-rays, CT scans, MRI, and ultrasound help visualize internal organs and tissues. - Biopsy: A tissue sample is taken and examined under a microscope to confirm the presence of cancer cells. - Blood Tests: Specific markers in the blood can indicate certain types of cancer.
