Cancer treatment and symptoms

Signs and symptoms are both signals of injury, illness, disease – signals that something is not right in the body. A sign is a signal that can be seen by someone else – maybe a loved one, or a doctor, nurse, or other health care professional. For example, fever, fast breathing, and abnormal lung sounds heard through a stethoscope may be signs of pneumonia. A symptom is a signal that’s felt or noticed by the person who has it, but may not be easily seen by anyone else. For example, weakness, aching, and feeling short of breath may be symptoms of pneumonia. Having one sign or symptom may not be enough to figure out what’s causing it. For example, a rash in a child could be a sign of a number of things, such as poison ivy, measles, a skin infection, or a food allergy. But if the child has the rash along with other signs and symptoms like a high fever, chills, achiness, and a sore throat, then a doctor can get a better picture of the illness. Sometimes, a patient’s signs and symptoms still don’t give the doctor enough clues to be sure what’s causing the illness. Then medical tests, such as x-rays, blood tests, or a biopsy may be needed.
Treatment works best when cancer is found early – while it’s still small and is less likely to have spread to other parts of the body. This often means a better chance for a cure, especially if the cancer can be removed with surgery. A good example of the importance of finding cancer early is melanoma skin cancer. It can be easy to remove if it has not grown deep into the skin. The 5-year survival rate (percentage of people who live at least 5 years after diagnosis) at this early stage is around 98%. Once melanoma has spread to other parts of the body, the 5-year survival rate drops to about 16%.
