Regular screening for cervical, colorectal, and breast cancers detects the disease at an early stage, when the chance for survival and cure is high. A heightened awareness of warning signs for cancer of the oral cavity, skin, and some other cancers may also lead to detection of cancers at an early stage.
Effective treatment (surgery, chemotherapy, and radiation) has been developed for several cancers, including cancers of the breast, colon and rectum, and testis and for many childhood cancers. For certain cancers such as testis, treatment could lead to cure even for advanced stage disease. Pain associated with cancer can be controlled by administration of analgesic drugs. Full application of these interventions globally could prevent a substantial proportion of cancer deaths worldwide.
