Squeezing through tiny blood vessels may trigger melanoma metastasis

Squeezing through tiny blood vessels may trigger melanoma metastasis, a study suggests.

Why it matters

  • Metastasis is deadly in most cancers.
  • Finding could aid treatment.

By the numbers

  • 9 of 10 common cancer deaths in Australia are due to solid tumors.
  • Channels narrower than 10 micrometres (1/5 width of human hair) cause cell changes.

The big picture

  • Supports theory that pressure in blood vessels makes cancer aggressive.
  • Could lead to new prevention strategies.

What they're saying

  • Study backs long-held theory on pressure and cancer aggression.
  • Piezo1 channel noted for its broad involvement.

Caveats

  • Lab/mice studies only so far.

What’s next

  • More microfluidics work planned.
