Correction

A New York Times News Service article published in the Taipei Times Tuesday July 31 under the headline "The Cancer Maze," about the uneven quality of medical care for cancer, gave an incomplete list of cancers that can be prevented or cured with surgery alone. Skin, cervical and colorectal cancer can be prevented if pre-cancerous lesions are detected and removed. Melanoma and other skin cancers, along with cancers of the prostate, breast, colon, rectum and cervix, can sometimes be cured with surgery if diagnosed early and removed. Colorectal and cervical cancers are not the only ones preventable or curable by surgery alone.
