Cancer radiation treatment will be cut from two months of daily visits down to a single ten minute hit, if trials beginning today at Peter MacCallum Cancer Centre in Melbourne are successful.

Patients with inoperable forms of lung and liver cancer, as well as those with hard-to-treat colorectal, kidney and prostate cancers will be the first to test the new treatment method.

Since 2010, an average of four cancer patients each week have been treated with a high-dose Stereotactic Ablative Body Radiation (SABR) Therapy.

A team of experts has combined mathematical modelling to determine how much radiation could be delivered to a patient by removing the laser's filter, and overriding default settings to deliver a much stronger beam.

SABR had already reduced treatment time from an eight-week period to around five one-hour sessions.

There are now hopes the intensified treatment method will deliver a more accurate dose but with fewer side-effects.

Harold Sciberras was today the first patient in Australia to undergo the treatment, receiving a single, high dose of radiation targeting a tumour in his lung.

"For him to be able to come in for a single treatment and go home the same day and not having to worry about anything ater that, it's really great," Dr Shankar Siva told 9NEWS.

After the treatment, Mr Sciberas said it felt as if nothing had been done at all.
