Phototherapy is a safe, and secure way to destroy cancer cells when light waves of a particular wavelength used with appropriate activating agents. It is usually limited by its nature to illnesses that are skin-deep. Researchers developed a phototherapy method that brings light directly to tumor cells, no matter how deep they are. Phototherapy also has demonstrated promising results in diagnosing and treating various types of cancers. The combination of nanomedical agents and phototherapy modalities has shown better results than individual therapy. Further research should be encouraged to formulate an effective combination of activating agents and phototherapy for the best outcome, to minimize adverse effects and to prevent injury to healthy tissues. This article reviews different types phototherapy methods to treat cancer.

Traumatic brain injuries are common with sports-related injuries. The signs and symptoms vary from mild to severe with examples of a mild headache or nausea alone to more severe symptoms such as coma or death. Furthermore, studies have shown chronic repercussions of traumatic brain injuries such as Alzheimer's disease or dementia late in life. Immediate evaluation and a timely diagnosis is the most important in the treatment of sports-related brain injuries since it has been proven to lead to a better prognosis following the injury. Promoting health awareness with an emphasis on education, injury prevention, early recognition, and effective management of injuries may avert premature death and devastating early onset of neurodegenerative disease.
