Cancer Detection and Diagnosis:Detecting and diagnosing cancer includes evaluating the presence of cancer in the body and determining the nature of the disease. Expanding the ability to detect precancerous lesions on the verge of developing into life-threatening cancers will allow for early intervention, potentially preventing cancer from developing at all. Patients would be spared the physical and financial risks of premature surgery, as well as the psychological harms of a cancer diagnosis, if they were diagnosed with potentially lethal cancers. Additional studies will enable the way for the advancement of more responsive, reliable preventive approaches in the future like Cost-effective methods of detecting, diagnosing and preventing cancer.
