Cancer Symptoms Introduction
Cancer often has no specific symptoms, so it is important that people limit their risk factors and undergo appropriate cancer screening. Most cancer screening is specific to certain age groups and your primary-care doctor will know what screening to perform depending on your age. People with risk factors for cancer (for example, smokers, heavy alcohol use, high sun exposure, genetics) should be acutely aware of potential cancer symptoms and be evaluated by a physician if any develop.
Consequently, individuals need to know which symptoms might point to cancer. People should not ignore a warning symptom that might lead to early diagnosis and possibly to a cure.

CT scanners first began to be installed in 1974. Currently, 6,000 scanners are in use in the United States. Because of advances in computer technology, CT scanners have vastly improved patient comfort because they are now much faster. These improvements have also led to higher-resolution images, which improve the diagnostic capabilities of the test. For example, the CT scan can show doctors small nodules or tumors, which they cannot see on an x-ray.
