Fotoniterapia, also known as photodynamic therapy (PDT), is a medical treatment that uses a combination of light, a photosensitizing drug, and oxygen to kill damaged cells. The photosensitizing drug is administered to the patient and selectively accumulates in abnormal cells, such as cancer cells. When a specific wavelength of light is applied to the treated area, it activates the drug. This activation creates a chemical reaction that produces reactive oxygen species, which are highly toxic to the cells where the drug has accumulated.

PDT can be used to treat a variety of conditions, including certain types of cancer (like skin cancer, esophageal cancer, and lung cancer), precancerous lesions, and certain eye conditions like macular degeneration. The light source can be a laser or a light-emitting diode (LED), and the wavelength is chosen to match the absorption spectrum of the photosensitizing agent. The treatment is often delivered in a clinic or hospital setting.

The advantages of PDT include its targeted nature, which can minimize damage to surrounding healthy tissues, and its ability to be repeated if necessary. However, potential side effects can include temporary skin sensitivity to light, redness, swelling, and pain at the treatment site. The specific drug and light source used will depend on the condition being treated and the location of the abnormal cells.
