Cancer is an abnormal cell growth and development.
By the time there are visible signs or symptoms of cancer, it may be too late. It is best to have regular visits to your doctor and to monitor your own health. Early detection can reduce suffering and save lives. Some cancers, like breast, testicular, and skin cancer, often can be detected early by self-exams. Others, such as cervical cancer or prostate cancer, can only be detected by your health care provider.
