What are signs 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.
How does cancer cause signs and symptoms?
Cancer is a group of diseases that can cause almost any sign or
symptom. The signs and symptoms will depend on where the cancer is, how
big it is, and how much it affects the organs or tissues. If a cancer
has spread (metastasized), signs or symptoms may appear in different
parts of the body.
As a cancer grows, it can begin to push on nearby organs, blood
vessels, and nerves. This pressure causes some of the signs and symptoms
of cancer. If the cancer is in a critical area, such as certain parts
of the brain, even the smallest tumor can cause symptoms.
But sometimes cancer starts in places where it won’t cause any
signs or symptoms until it has grown quite large. Cancers of the
pancreas, for example, usually don’t cause symptoms until they grow
large enough to press on nearby nerves or organs (this causes back or
belly pain). Others may grow around the bile duct and block the flow of
bile. This causes the eyes and skin to look yellow (jaundice). By the
time a pancreatic cancer causes signs or symptoms like these, it’s
usually in an advanced stage. This means it has grown and spread beyond
the place it started – the pancreas.
A cancer may also cause symptoms like fever, extreme tiredness
(fatigue), or weight loss. This may be because cancer cells use up much
of the body’s energy supply, or they may release substances that change
the way the body makes energy from food. Cancer can also cause the
immune system to react in ways that produce these signs and symptoms.
Sometimes, cancer cells release substances into the bloodstream
that cause symptoms that are not usually linked to cancer. For example,
some cancers of the pancreas can release substances that cause blood
clots in veins of the legs. Some lung cancers make hormone-like
substances that raise blood calcium levels. This affects nerves and
muscles, making the person feel weak and dizzy.
How are signs and symptoms helpful?
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%.
Sometimes people ignore symptoms. Maybe they don’t know that the
symptoms could mean something is wrong. Or they might be frightened by
what the symptoms could mean and don’t want to get medical help. Maybe
they just can’t afford to get medical care.
Some symptoms, such as tiredness or coughing, are more likely
caused by something other than cancer. Symptoms can seem unimportant,
especially if there’s a clear cause or the problem only lasts a short
time. In the same way, a person may reason that a symptom like a breast
lump is probably a cyst that will go away by itself. But no symptom
should be ignored or overlooked, especially if it has lasted a long time
or is getting worse.
Most likely, symptoms are not caused by cancer, but it’s important
to have them checked out, just in case. If cancer is not the cause, a
doctor can help figure out what the cause is and treat it, if needed.
Sometimes, it’s possible to find cancer before having symptoms. The
American Cancer Society and other health groups recommend
cancer-related check-ups and certain tests for people even though they
have no symptoms. This helps find certain cancers early, before symptoms
start. For more information on early detection tests, see our document
called American Cancer Society Guidelines for the Early Detection of
Cancer. But keep in mind, even if you have these recommended tests, it’s
still important to see a doctor if you have any symptoms.
What are some general signs and symptoms of cancer?
You should know some of the general signs and symptoms of cancer.
But remember, having any of these does not mean that you have cancer –
many other things cause these signs and symptoms, too. If you have any
of these symptoms and they last for a long time or get worse, please see
a doctor to find out what’s going on.
Unexplained weight loss
Most people with cancer will lose weight at some point. When you
lose weight for no known reason, it’s called an unexplained weight loss.
An unexplained weight loss of 10 pounds or more may be the first sign
of cancer. This happens most often with cancers of the pancreas,
stomach, esophagus (swallowing tube), or lung.
Fever
Fever is very common with cancer, but it more often happens after
cancer has spread from where it started. Almost all people with cancer
will have fever at some time, especially if the cancer or its treatment
affects the immune system. (This can make it harder for the body to
fight infection.) Less often, fever may be an early sign of cancer, such
as blood cancers like leukemia or lymphoma.
Fatigue
Fatigue is extreme tiredness that doesn’t get better with rest. It
may be an important symptom as cancer grows. But it may happen early in
some cancers, like leukemia. Some colon or stomach cancers can cause
blood loss that’s not obvious. This is another way cancer can cause
fatigue.
Pain
Pain may be an early symptom with some cancers like bone cancers or
testicular cancer. A headache that does not go away or get better with
treatment may be a symptom of a brain tumor. Back pain can be a symptom
of cancer of the colon, rectum, or ovary. Most often, pain due to cancer
means it has already spread (metastasized) from where it started.
Skin changes
Along with skin cancers, some other cancers can cause skin changes that can be seen. These signs and symptoms include:
- Darker looking skin (hyperpigmentation)
- Yellowish skin and eyes (jaundice)
- Reddened skin (erythema)
- Itching (pruritis)
- Excessive hair growth
- Signs and symptoms of certain cancers
Along with the general symptoms, you should watch for certain other
common signs and symptoms that could suggest cancer. Again, there may
be other causes for each of these, but it’s important to see a doctor
about them as soon as possible – especially if there’s no other cause
you can identify, the problem lasts a long time, or it gets worse over
time.
Change in bowel habits or bladder function
Long-term constipation, diarrhea, or a change in the size of the
stool may be a sign of colon cancer. Pain when passing urine, blood in
the urine, or a change in bladder function (such as needing to pass
urine more or less often than usual) could be related to bladder or
prostate cancer. Report any changes in bladder or bowel function to a
doctor.
Sores that do not heal
Skin cancers may bleed and look like sores that don’t heal. A
long-lasting sore in the mouth could be an oral cancer. This should be
dealt with right away, especially in people who smoke, chew tobacco, or
often drink alcohol. Sores on the penis or vagina may either be signs of
infection or an early cancer, and should be seen by a health
professional.
White patches inside the mouth or white spots on the tongue
White patches inside the mouth and white spots on the tongue may be
leukoplakia. Leukoplakia is a pre-cancerous area that’s caused by
frequent irritation. It’s often caused by smoking or other tobacco use.
People who smoke pipes or use oral or spit tobacco are at high risk for
leukoplakia. If it’s not treated, leukoplakia can become mouth cancer.
Any long-lasting mouth changes should be checked by a doctor or dentist
right away.
Unusual bleeding or discharge
Unusual bleeding can happen in early or advanced cancer. Coughing
up blood may be a sign of lung cancer. Blood in the stool (which can
look like very dark or black stool) could be a sign of colon or rectal
cancer. Cancer of the cervix or the endometrium (lining of the uterus)
can cause abnormal vaginal bleeding. Blood in the urine may be a sign of
bladder or kidney cancer. A bloody discharge from the nipple may be a
sign of breast cancer.
Thickening or lump in the breast or other parts of the body
Many cancers can be felt through the skin. These cancers occur
mostly in the breast, testicle, lymph nodes (glands), and the soft
tissues of the body. A lump or thickening may be an early or late sign
of cancer and should be reported to a doctor, especially if you’ve just
found it or notice it has grown in size. Keep in mind that some breast
cancers show up as red or thickened skin rather than a lump.
Indigestion or trouble swallowing
Indigestion or swallowing problems that don’t go away may be signs
of cancer of the esophagus (the swallowing tube that goes to the
stomach), stomach, or pharynx (throat). But like most symptoms on this
list, they are most often caused by something other than cancer.
Recent change in a wart or mole or any new skin change
Any wart, mole, or freckle that changes color, size, or shape, or
that loses its sharp border should be seen by a doctor right away. Any
other skin changes should be reported, too. A skin change may be a
melanoma which, if found early, can be treated successfully. See
pictures of skin cancers and other skin conditions in our Skin Cancer
Image Gallery.
Nagging cough or hoarseness
A cough that does not go away may be a sign of lung cancer.
Hoarseness can be a sign of cancer of the larynx (voice box) or thyroid
gland.
Other symptoms
The signs and symptoms listed above are the more common ones seen
with cancer, but there are many others that are not listed here. If you
notice any major changes in the way your body works or the way you feel –
especially if it lasts for a long time or gets worse – let a doctor
know. If it has nothing to do with cancer, the doctor can find out more
about what’s going on and, if needed, treat it. If it is cancer, you’ll
give yourself the chance to have it treated early, when treatment works
best.
