Cancer, lately, has become one of the major menaces to human life. Cancer when detected early increases the chances of successful treatment and hence prolongs the overall survival. Diagnosing it at an early stage before it has spread or it is too big increases the chances of successful treatment. By the time symptoms appear, cancer may have begun to spread and is difficult to treat. This can be done by two methods-cancer screening and recognition of the possible warning signs of cancer.
Screening for Cancer:
Screening means testing your body for cancer to identify individuals who have the disease but do not have any symptoms. Screening tests are particularly helpful in detecting breast, cervical, colorectal cancers early. Examples include mammography for breast cancer and pap smears (cervical cytology) for cervical cancer.
Complications due to opting for cancer screening at later stages:
More than 90% of the patients with breast, ovarian and bowel cancer have better survival rate compared to those diagnosed with advanced disease. Most of the cancers are diagnosed at a later stage.
