Many are caused by harmless conditions, such as cysts, fatty growths, or swollen lymph nodes associated with an infection. Nevertheless, an unexplained lump that persists or changes should be assessed by a healthcare professional.
Lumps may appear in several areas, including:
-
The breast or chest.
-
The neck.
-
The armpit.
-
The groin.
-
The abdomen.
-
Other soft tissues beneath the skin.
Some cancers can cause a lump because abnormal cells grow into a mass. Breast cancer, for example, may present as a new breast lump or an area of thickening. Certain blood cancers may cause persistent enlargement of lymph nodes.
A lump's appearance or texture cannot reliably establish whether it is cancerous. Some harmless lumps feel firm, while some concerning lumps may not cause pain.
Look for changes such as increasing size, persistent swelling, a new area of thickening, or a lump accompanied by other unexplained symptoms.
When should you have it checked?
Arrange a medical appointment for a new or unexplained lump, particularly if it persists, grows, or feels different from the surrounding tissue.
A healthcare professional may examine the area and recommend imaging or other tests if needed.
Do not wait for a lump to become painful before seeking advice. Some important conditions, including certain cancers, may initially cause little or no discomfort.
4. Unusual Bleeding or Bruising
Bleeding that occurs unexpectedly or without an obvious explanation should never be ignored.
The location and pattern of the bleeding can help determine the possible cause. For example, blood in the urine, blood in the stool, unusual vaginal bleeding, or coughing up blood may require specific investigations.
Some cancers can affect tissues, blood vessels, or the normal production of blood cells. As a result, abnormal bleeding may occasionally be an early symptom.
Potential warning signs include:
-
Blood in the urine, even if it occurs only once.
-
Red blood in the stool or unusually dark, tarry stools.
-
Vaginal bleeding between periods or after menopause.
-
Bleeding after sexual intercourse.
-
Coughing up blood.
-
Repeated unexplained bruising.
-
Bleeding that is unusually heavy or difficult to stop.
There are many non-cancerous explanations for these symptoms. Hemorrhoids, urinary tract infections, menstrual changes, medication effects, and clotting disorders can all cause bleeding.
However, the possibility of a less serious explanation does not mean that an assessment is unnecessary.
Why does the location matter?
Blood in the urine may require evaluation of the urinary tract. Blood in the stool can arise from several digestive conditions, ranging from hemorrhoids to inflammatory bowel disease and colorectal cancer.
Unusual vaginal bleeding, particularly after menopause, also warrants prompt medical assessment.
Seek urgent medical advice for unexplained bleeding. Go to an emergency department if bleeding is heavy or ongoing, you vomit blood, you pass a large amount of blood, or you develop faintness, severe weakness, or difficulty breathing.
5. Changes in Bowel Habits That Persist
Digestive changes are common. A change in diet, travel, stress, medication, or a temporary infection can affect how frequently you have bowel movements and how your stool looks.
The concern arises when a change is unusual for you, persists, or occurs alongside other unexplained symptoms.
Possible changes include:
-
Constipation that does not improve.
-
Diarrhea that continues or repeatedly returns.
-
A persistent change in stool consistency.
-
A new and lasting change in bowel frequency.
-
Blood in the stool.
-
Ongoing abdominal discomfort or bloating.
-
A persistent sensation that you have not completely emptied your bowels.
Colorectal cancer can cause changes in bowel habits, but these symptoms are also associated with many other conditions.
The pattern matters. For example, a short episode of diarrhea after a stomach infection is different from a persistent change that continues without a clear explanation.
Other digestive warning signs include unexplained weight loss, reduced appetite, and fatigue that could be related to anemia from blood loss.
When should you seek medical advice?
Arrange an appointment if a bowel habit change persists, repeatedly returns, worsens, or occurs with blood in the stool or unexplained weight loss.
Do not wait for severe abdominal pain to develop. Some digestive conditions can progress without producing intense pain in the early stages.
If your stool is black and tarry, you have substantial rectal bleeding, or you experience severe abdominal pain, fainting, or marked weakness, seek urgent medical care.
6. A Persistent Cough or a Voice That Becomes Hoarse
Coughing is a natural response that helps clear irritants and mucus from the airways. A cough can follow a cold, occur with allergies, or be associated with asthma and acid reflux.
However, a cough that does not improve, becomes progressively worse, or differs noticeably from your usual pattern deserves attention.
