It refers to the development of secondary tumors at different locations in the body from the original cancer. Eventually, these tumors interfere with vital body functions, and if left uncontrolled, will prove fatal. The most common areas for metastasis to occur are in the bones, lungs, liver, and central nervous system. Once a cancer has spread to other parts of the body, it is much harder to treat successfully. That's why it is so important to have regular check-ups and cancer screenings.
Early detection is the best protection.
For more information on the spread of cancer, contact a health care professional. Many times it's the patient, not the doctor, who first notices the warning signs of cancer. The American Cancer Society has listed seven basic warning signs, and it is recommended that you investigate any of these symptoms without delay. If you experience any one, or a combination of these symptoms, talk with your doctor. A regular health checkup is your first line of defense against cancer.
