INSIGHT

Liquid Biopsy for Early Cancer Detection

  • Liquid biopsies use cell-free DNA methylation patterns to detect 50+ cancer types early.
  • Early detection is crucial for higher curability due to fewer mutations in cancer cells.
INSIGHT

Grail's Liquid Biopsy Technology

  • Grail's liquid biopsy analyzes cell-free DNA methylation, not tumor DNA, for better cancer detection.
  • Tumor DNA represents only a tiny fraction of cell-free DNA, making methylation analysis more effective.
ADVICE

Cancer Prevention and Screening

  • Prioritize cancer prevention through a healthy lifestyle and aggressive screening.
  • Use multiple screening methods to cover each other's blind spots, like Swiss cheese.
