The standard practice of removing
small throat tumours using laser is
ineffective against the larger ones, so
a new procedure using a special drug
and light rays can reduce the suffering of patients, if not cure them.
The drug called photofrin -
manufactured by QLT Phototherapeutics Incorporated of Vancouver
in Canada -helped in clearing
large tumours in the throats of half
the patients it was tried on.
Photofrin makes the tumour light-
sensitive and the beams of light that
follow, kill the cancer cells.
