Signs and Symptoms of Cancer emoticon
What are signs and symptoms?
Signs and symptoms are both signals of injury, illness, disease, or that something is not right in the body.

A sign is a signal that can be seen by someone elseómaybe 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 is 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 whatís 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 patientís signs and symptoms still donít give the doctor enough clues to be sure what is 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 will not cause any signs or symptoms until it has grown quite large. Cancers of the pancreas, for example, usually do not 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, itís usually in an advanced stage. This means it has grown and spread beyond the place it startedóthe 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 bodyís energy supply, or they may release substances that change the way the body makes energy from food. Or the cancer may 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 which 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 earlyówhile itís 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 stage is around 97%. Once melanoma has spread to other parts of the body, the 5-year survival rate drops below 20%.

Sometimes people ignore symptoms. Maybe they donít know that the symptoms could mean something is wrong. Or they might be frightened by what the symptoms could mean and donít want to get or canít afford to get medical help. Some symptoms, such as tiredness or coughing, are more likely caused by something other than cancer. Symptoms can seem unimportant, especially if thereís an obvious 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, any symptoms you may have will not be caused by cancer, but itís important to have them checked out, just in case. If cancer is not the cause, a doctor can help figure out what is and treat it, if needed.

Sometimes, itís possible to find cancer before you have 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 American Cancer Society Guidelines for the Early Detection of Cancer. But keep in mind, even if you have these recommended tests, itís 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 cancerómany 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 whatís going on.

Unexplained weight loss

Most people with cancer will lose weight at some point. When you lose weight for no known reason, itís 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 patients 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 does not get better with rest. It may be an important symptom as cancer grows. It may happen early, though, in some cancers, like leukemia. Some colon or stomach cancers can cause blood loss thatís 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 cancers of the skin, 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 itís important to see a doctor about them as soon as possible.

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 donít 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 thatís caused by frequent irritation. Itís 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 itís 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 in the sputum (phlegm) 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 youíve 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 the expected lump.

Indigestion or trouble swallowing

Indigestion or swallowing problems that donít 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.

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 voice box (larynx) 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 Ė especially if it lasts for a long time or gets worse Ė let a doctor know. If it has nothing to do with cancer, the doctor can find out more about whatís going on and, if needed, treat it. If it is cancer, youíll give yourself the chance to have it treated early, when treatment works best. emoticon emoticon
