Australian study: Aspirin could beat cancer spread

Tue, Feb 14, 2012

Doctors have long suspected that non-steroidal anti-inflammatory drugs such as aspirin may help inhibit the spread of cancer but they have been unable to pinpoint exactly how this is done.

By studying cells in lymphatic vessels, the researchers found that a particular gene changed its expression in cancers which spread, but not when the cancer did not spread.

The results published in Cancer Cell journal reveal that the gene is a link between a tumour's growth and the cellular pathway which can cause inflammation and dilation of vessels throughout the body.

Once these lymphatic vessels widen, the capacity for them to act as "supply lines" to tumours and become more effective conduits for the cancer to spread is increased.

But aspirin acts to shut down the dilation of the vessels. the rest image
