Cancer detection refers to the process of identifying cancer in the body, often through various screening methods. Common techniques include imaging tests like X-rays, CT scans, and MRI, as well as laboratory tests such as blood tests and biopsies. Early detection is crucial, as it can significantly improve treatment outcomes and survival rates. Screening guidelines vary based on factors like age, gender, and family history. For example, mammograms are recommended for women to detect breast cancer, while colonoscopies are advised for colorectal cancer screening. Regular check-ups and awareness of symptoms can aid in timely diagnosis.
