Photodynamic Therapy Clinic

Photodynamic Therapy (PDT) is a form of phototherapy using non-toxic light sensitive compounds that are exposed selectively to light, as a result of which they become toxic to targeted malignant and other diseased cells. PDT has proven ability to kill microbial cells, including bacteria, fungi and viruses. PDT is used clinically to treat a wide range of medical conditions, including non-malignant cancers and is recognized as a treatment strategy which is both minimally invasive and minimally toxic.

Non-Melanoma Skin Cancer – There are two types of non-melanoma skin cancers and both are found in the outer layer of the skin, the epidermis:

1. Basal Cell Carcinoma – Arises from the uncontrolled multiplication of basal cells and are small, round cells found in the lower part of the epidermis.

2. Squamous Cell Carcinoma – Arises from the uncontrolled multiplication of squamous cells and are flat, scale-like cells found in the upper part of the epidermis.

Like all skin cancers, exposure to UV light (the sun) is the biggest cause of non-melanoma skin cancer, other factors that may increase the risk are fair coloured skin and old age.
