Breakthroughs of using Photodynamic Therapy and Gold Nanoparticles in Cancer Treatment

摘要

The term “cancer” covers more than a hundred diseases that assign one trait: the abandoned growth of abnormal cells that abolish healthy tissues and have the potential to spread outside its site of origin. When a malignant tumor originates in the breast, it is called breast cancer. Gold nano particles display potential for both the imaging and cure of breast cancer. From a logistical standpoint, most breast tumors arise near the skin's surface, where they may possibly be extracted and handled despite the NIR laser's minimal tissue penetration. Photodynamic therapy is a fairly new treatment option for both cancer and non-cancer diseases that involves the activation of certain dyes with light in the existence of molecular oxygen (photosensitizers) that the target tissue has absorbed in a very selective manner. The combination of hyperthermia and photoelectric dose improvement of radiation therapy could be effectively treat superficial positioned inflammatory breast cancer sorrecurrence in the post-mastectomy chest wall. In this review paper, the novel work in photothermal therapy is debated, as well as the combined effects of gold nanoparticles and photothermal heating on breast cancer cells are studied in details.
