When the photosensitizer is subjected to a light with a coordinating spooky array, it's converted from its ground state into a fired up singlet state. This enables it to move energy to molecular oxygen, generating singlet oxygen and totally free radicals that mediate cellular toxicity.
The Light
During treatment, a special light is radiated on the location where the photosensitizer was used. This light turns on the medicine and damages cancer cells or precancerous cells that it has actually targeted.
The medicines that are made use of in photodynamic treatment have various absorption residential or commercial properties and a few of them may take hours to leave typical cells however stay longer in cancer cells or precancer cells.

The photosensitizer is provided into the skin through topical, dental or intravenous management. It is soaked up by the growth cells and activated when exposed to light of a specific wavelength. This causes a sequence of photochemical reactions that creates reactive oxygen species (ROS) that damage tumor cells and kill cancer cells.

It can be made use of alone or with various other treatments, such as surgery or radiation.

After the treatment, your body normally throws away the dead cells. Patients with lung cancer cells might experience coughing up blood or have a bronchoscopy to clear the lungs of the dead cells. In some cases, your medical professionals may make use of a bronchoscopy to remove the photosensitizer from the lungs too if it causes severe signs and symptoms. It is very important to stay inside your home and make use of sunscreen when you go outside while the photosensitizer remains in your system.
