Early Diagnosis of Colorectal Cancer Using Gold Nanoparticles ? a Pilot Study

Noguda Njabulo

Colorectal cancer (CRC) is ranked amongst the top three most diagnosed cancers in humans worldwide. Colorectal cancer is the fourth most common cancer in South Africa and the sixth most common cause of death. If diagnosed during the early stages, the 5year relative survival rate can be as high as 90%. However, in most cases, the diagnosis is only made at a later stage when the cancer has metastasized, as the detection depends on the symptoms and non-specific screening. Many attempts have been made to achieve an early detected of CRC.
