Method: Patients who was having diabetes from last 10-12 years was taken as sample and start to determine the impacts of diabetes on human health and how cancer germs get generated in the body of diabetic patients. Result: Patients with type 2 diabetes was having chances of cancer 13% but type 1 diabetic patient was just having 2-3% of cancer patients between them. Some precautionary measure should be taken to prevent people and to give them awareness about cancer with diabetes and how to get rid of this issue which is facing worldwide. After this whole research we concluded it as we have taken about 951 are linked with type 2 diabetes and 340 are linked with type 1 diabetes. Some of them was not going for their regular checkup from one year and other was going on regular bases. In this study, after different calculations we have given them insulin and also given tablets fir diabetes too few of them. Conclusion: By checking the range of cancer in their bodies, there was not as much difference between those patients who was taking tablets then to those who was injecting insulin. Different types of cancer got diagnosed between them as breast cancer in women, colon cancer, throat cancer, lung cancer etc. Lung cancer mostly occur due to smoking. But most of the patients was those who was just having diabetes as it is either type 1 diabetes or type 2 diabetes but they did not have cancer with their diabetes.
