Cancer is a very complex disease, and depending on the type of cancer that the patient has, the treatments can vary. Treatments are also based on other factors, such as the patient’s age, medical history, etc. Among the common types of treatment used for cancer patients, you will find surgery, chemotherapy, and radiation treatment, and commonly a combination of treatments. The type of treatment can depend on the type, location, level, and stage of the cancer that is being treated.
Another form of treatment linked to cancer treatment is PDT, or Photodynamic Therapy. This is a type of therapy that uses a drug that is known as a photosensitizing agent, and this agent is activated by exposure to light. It is then used to try and destroy cancer cells within the body. The agent can be used in a number of ways, such as topical application or injection directly into the bloodstream. It can take several days to absorb before light sources are used to target the relevant area and activate the agent.
This is a type of treatment that has the benefit of being very targeted, and therefore, it can affect the cancer cells in the affected area in order to try and destroy them. Chemotherapy, on the other hand, can affect good cells as well as cancerous ones because it is not localized to one area. Another benefit to PDT is that is can be used over and over in the same area without causing damage in the way that radiation therapy can cause damage if used repeatedly in the same area.
In order to benefit from PDT, the area where the cancer cells are needs to be accessible by light, and this means the skin and also the lining of major organs in the body. Mesothelioma is a type of cancer that affects the lining of the organs, such as the lungs, the heart, and the abdominal organs, and therefore patients with this type of cancer could benefit from PDT.
