Cancer is one of the leading causes of death worldwide, but many types are preventable or treatable when detected early.
Cancer occurs when abnormal cells grow uncontrollably. There are more than 100 types of cancer, each with unique characteristics and treatment approaches.
When cancer is detected early, treatment success rates increase dramatically. Common screening methods include mammograms, colonoscopies, PSA tests, and skin checks.
