Yes, physical examination can detect cancer. Through various medical checkups, such as ultrasound, X-ray, blood draw, etc., abnormalities in the body can be detected at an early stage, so that early treatment can be carried out to improve the cure rate and survival rate.

There are different physical examination methods for different cancers, such as breast cancer can be examined by breast ultrasound or molybdenum target photography, etc. Stomach cancer can be examined by gastroscopy and gastric tissue biopsy, etc. Liver cancer can be examined by ultrasound, CT or NMR*** vibration.

In addition to traditional medical checkups, there are some emerging medical checkups, such as genetic testing and blood marker testing, that can also help detect cancer. For example, genetic testing can predict an individual's risk of developing certain cancers and take early preventive measures.

Therefore, it is recommended that people undergo regular medical checkups, especially for those at high risk of certain cancers, such as those with a family history of cancer and long-term smokers, to enhance their medical checkups for early detection and treatment of cancer.
