Light Therapy Spares the Scalpel and the Chemo -

Imagine you could treat cancer by taking a pill, then directing a laser light toward the location of the tumor. The growth would dissolve with no chemotherapy, and no harm to healthy tissue.

It might sound futuristic, but a select number of cancer patients already benefit from the method, called photodynamic therapy. An upgrade for the procedure could save thousands more cancer patients from the horrors of chemotherapy.

Although chemotherapy has improved over the past decade, the treatment still damages healthy tissue and causes other unpleasant side effects like nausea and a weakened immune system. The researchers hope their work will spare patients from chemo's ravages and even the surgery usually necessary to remove a tumor.
