Early detection of cancer has multitude of advantages like early diagnosis, reduced risk, ease in the treatment and follow up of recurrence. New and developed techniques are always under research to control the spreading malignancy. Graphene is an emerging star in biomedical field as it exhibits exceptional thermal, electrical and optical properties. Here, we review application of graphene-based materials in developing biosensing devices for the detection of different cancer biomarkers at concentrations down to sub-toxic levels. Different analytical methodologies chosen for sensing have been undertaken and their performance and background have been discussed. The trend of use of these methodologies can also be perceived from the graphical data presented.

早期发现癌症具有许多优势，如早期诊断，降低风险，易于治疗和随访复发。为了控制恶性肿瘤的扩散，一直在研究新技术。石墨烯是生物医学领域的新兴明星，因为它具有出色的热，电和光学性能。在这里，我们回顾了基于石墨烯的材料在开发生物传感设备中的应用，以检测低至亚毒性水平的不同癌症生物标志物。已经选择了用于感测的不同分析方法，并且已经讨论了它们的性能和背景。这些方法的使用趋势也可以从提供的图形数据中看出。
