A light-sensitive drug is injected into the lesion. A laser is then shone directly onto the lesion. The drug is activated by the laser, and destroys the cancer cells. This is a new treatment, and at the moment its value is still being assessed. The chemotherapy drugs are contained in fat-based cells called liposomes.
Liposomes are able to travel to the tumour site, where they release the drug.
The advantage of this type of chemotherapy is that there are fewer side effects, which means treatment can be given over a longer period. All rights reserved. Readers are strongly advised to discuss the information with their doctor.
