What is a common method of cancer detection?

Regular physical examinations are a common method of cancer detection because they allow healthcare providers to assess a patient's overall health and identify any unusual changes that could indicate the presence of cancer. These examinations can include palpation of breast tissue, examination of lymph nodes, skin checks, and other assessments that may reveal abnormalities. Early detection of cancers through regular check-ups is crucial as it can lead to earlier interventions and better outcomes in treatment.

In contrast, while radiation therapy is an important treatment modality for cancer, it is not a detection method; rather, it is used to destroy cancer cells. Genetic testing can help identify individuals at increased risk for certain types of cancer but is not routinely used for detecting cancer in symptomatic individuals. Patient self-reporting can provide valuable information about symptoms but is less systematic and reliable than clinical examinations conducted by trained professionals during regular physical exams.
