Signs and Symptoms of Cancer
What Are Symptoms and Signs?
A symptom is an indication of disease, illness, injury, or that
something is not right in the body. Symptoms are felt or noticed by a
person, but may not easily be noticed by anyone else. For example,
chills, weakness, achiness, shortness of breath, and a cough are
possible symptoms of pneumonia.
A sign is also an indication that something is not right in the body.
But signs are defined as observations made by a doctor, nurse, or
other health care professional. Fever, rapid breathing rate, and
abnormal breathing sounds heard through a stethoscope are possible
signs of pneumonia.
The presence of one symptom or sign may not give enough information to
suggest a cause. For example, a rash in a child could be a symptom of
a number of things including poison ivy, an infectious disease like
measles, an infection limited to the skin, or a food allergy. But if
the rash is seen 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. In many cases, a patient's signs and
symptoms do not provide enough clues by themselves to determine the
cause of an illness, and medical tests such as x-rays, blood tests, or
a biopsy may be needed.
How Are Signs and Symptoms Helpful?
Treatment is most successful when cancer is found as early as
possible. Finding cancer early usually means it can be treated while
it is 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
initial treatment is to be surgery.
A good example of the importance of detecting cancer early is melanoma
skin cancer. It is easily removed if it has not yet grown deeply into
the skin, and the 5-year survival rate (percentage of people living at
least 5 years after diagnosis) at this stage is nearly 100%. But once
melanoma has spread to other parts of the body the survival rate drops
dramatically.

Sometimes people ignore symptoms either because they do not recognize
the symptoms as being significant or because they are frightened by
what they might mean and don=92t want to seek medical help. General
symptoms, such as fatigue, are more likely to have a cause other than
cancer and can seem unimportant, especially if they have an obvious
cause or are only temporary. In a similar way, a person may reason
that a more specific symptom like a breast mass is probably a cyst
that will go away by itself. But neither of these symptoms should be
discounted or overlooked, especially if they have been present for a
long period of time or are getting worse.
