A synopsis of modern - day colorectal cancer: Where we stand

Colorectal cancer (CRC) is a malignancy in the gastro-intestinal (GI) tract which has very limited treatment options still, despite the vast amount of research undertaken. CRC was first discovered a century ago and is the third-highest cause of global cancer-related deaths. Once diagnosed as a T4 -stage carcinoma, the prognosis extends only up to two years at the best. Although resectable surgery remains the primary safeguard in combatting metastatic CRC, research had focussed on to various therapeutic and disease management strategies, such as stem cell - based therapies, CT, MRI, PET-CT scans, colonography, endoscopy and biologics. The struggle in developing an anti-cancer therapy may be due to its unresolved aetiology comprising of genetic abnormalities, and multiple risk factors in lifestyle, culture, and environment in the globally diverse, human populations. This review aims to summarize the prominent features of CRC which could encourage lifestyle changes and introduce novel clinically - relevant therapeutic strategies to improve its overall management.
