The National Cancer Institute’s authoritative Web site offers the latest information about cancer and its treatment. Here, you will find comprehensive information for more than 150 types of cancer, from the most common to the very rare. For each cancer type, there is information about causes, treatment, screening, and testing. For the more common cancers, such as breast, colon, lung, prostate, and others, the site provides summaries of recent clinical trial results. Information for each type of cancer is presented in two formats — for patients and for health professionals — in both English and Spanish. The patient version, written in lay language, may be especially useful for those newly diagnosed with cancer. Patients who have become more familiar with cancer, or those with a medical background, may prefer the more comprehensive and extensively referenced professional version.
The information on the site is updated regularly. Within each cancer, there are links to related topics. You can also find fact sheets about Cancer Staging and Tumor Grade, both of which affect cancer treatment choices and a patient’s prognosis. The site includes information about newly approved cancer treatments, cancer statistics, and a dictionary of more than 4,000 cancer-related terms with easy-to-understand definitions.
