What is Photodynamic Therapy?
A light-sensitive medication and particular light are used in photodynamic therapy (PDT), a minimally invasive cancer treatment, to kill cancer cells. This therapy provides a focused approach to treating cancers on the body's exterior or in areas where light can penetrate, including the skin, lungs, and digestive tract. The treatment of selected cancers with PDT has become more common because it delivers accurate results while causing fewer side effects and protecting healthy tissues.
The three essential components of photodynamic therapy are:
- Photosensitizing agent (drug): A special medication that makes cancer cells sensitive to light
- Light source: Usually a laser or specific wavelength light
- Oxygen: Present in the body's tissues
The light activates the drug at its site of accumulation, producing an oxygenated form that kills cancer cells.
How Photodynamic Therapy works?
PDT executes its process through three distinct steps:
- The healthcare provider administers the photosensitizing drug through intravenous injection or localized application.
- Cancer cells take up more drugs than normal cells.
- The tumor receives specific light treatment after a designated time period.
The activated drug produces reactive oxygen molecules that destroy cancer cells.
PDT executes its function by killing cancer cells through direct methods while also performing these extra functions:
- The system destroys the blood vessels that feed the tumor.
- The system activates the immune response to eliminate cancer cells.
Which types of cancers can be treated with photodynamic therapy?
PDT is commonly used for:
- Skin cancers and pre-cancerous lesions
- Lung cancer, especially early-stage or superficial tumors
- Esophageal cancer
- Certain head and neck cancers
It may also be used for non-cancerous conditions such as actinic keratosis.
When is Photodynamic Therapy Used?
Photodynamic therapy may be recommended:
- For early-stage cancers that are localized
- When surgery is not suitable or preferred
- To relieve symptoms in advanced cancers (palliative use)
- For recurrent cancers in previously treated areas
The method works best on tumors that doctors can reach with light.
How is photodynamic therapy administered?
The procedure depends on the tumor's location.
- Drug administration: The photosensitizer is given intravenously or applied topically
- Waiting period: Allows the drug to accumulate in cancer cells
- Light application: A laser or special light is directed at the tumor
Doctors can deliver light to internal cancers using endoscopic instruments placed inside the patient's body.
What can a patient expect during photodynamic therapy session?
PDT is often performed as an outpatient procedure, and it may take 5 minutes to 1 hour, depending on the treatment area.
Patients generally do not feel pain during the procedure, although some may experience mild discomfort or a warming sensation.
What are the Side Effects of Photodynamic Therapy?
Most patients tolerate PDT well, but they may experience certain side effects.
Possible Side Effects
- Redness, inflammation, and irritation of the affected area
- Sensitivity to light (photosensitivity)
- Mild pain or burning sensation
Photosensitivity Precaution
Patients who received treatment will develop sensitivity to both sunlight and bright indoor light for the next few days or weeks. The patient needs to:
- Avoid direct sunlight
- Wear protective clothing and sunglasses.
- Stay indoors as much as possible during the recovery period.
Less Common Effects
- Temporary difficulty swallowing (in esophageal treatment)
- Cough or breathing discomfort (in lung treatment)
What are the Benefits of Photodynamic Therapy?
Photodynamic therapy provides multiple benefits to patients.
- Minimally invasive with no major incisions
- Targets cancer cells with precision
- Preserves surrounding healthy tissue
- Can be repeated if necessary
The process requires a short recovery time for patients.
The method produces fewer long-lasting side effects than standard medical treatments.
What are the main drawbacks of photodynamic therapy?
Although photodynamic therapy has numerous benefits, there are some drawbacks:
- PDT can only be used effectively against easily accessible tumors
- Low light penetration into tissue
- Patients must follow strict light-avoidance protocols after the procedure.
- Large, deeply located tumors cannot be treated with photodynamic therapy.
Doctors decide whether the patient can receive this type of treatment.
What recent technological advancements have improved photodynamic therapy?
Many advances have been made in recent years regarding PDT effectiveness:
- More selective photosensitizing drugs have been developed recently.
- Superior light-delivering devices that can reach the deeper layers of tissue
- Combined with other treatment options like chemotherapy and immunotherapy
- Better imaging techniques that increase treatment accuracy
These advancements increasingly allow the use of PDT in cancer cases.
What does the recovery and follow-up process involve after photodynamic therapy?
PDT is a minimally invasive treatment, which implies a fast recovery. Usually, patients recover relatively quickly after the procedure and return to their daily routine shortly.
After the procedure, doctors should monitor:
- Treatment results
- Detection of side effects
- Further PDT sessions in case they are necessary
Multidisciplinary Cancer Treatment
As a rule, PDT is used in combination with other treatments to achieve optimal results.

Conclusion
Photodynamic Therapy is a non-invasive technique that kills cancer cells using light and a photosensitizing medication. Even though this type of treatment works better on certain cancers, it is still a very efficient way to kill cancer cells without many harmful side effects. With the rapid advancement of technology, photodynamic therapy is becoming increasingly valuable as a cancer treatment.
