4. Unusual Bleeding or Discharge
Unexpected bleeding can be alarming. For example:
-
Blood in urine may indicate bladder or kidney cancer.
-
Blood in stool can be a warning for colorectal cancer.
-
Unusual vaginal bleeding in women or nipple discharge in men and women can also be red flags.
Even coughing up blood or spotting blood when not expected requires immediate medical attention. While some bleeding may be caused by minor conditions, persistent or unexplained bleeding should never be ignored.
5. Persistent Pain
Pain is one of the most common signs that something may be wrong. Chronic pain—especially if it doesn’t have a clear cause—can sometimes indicate cancer.
For example, bone pain could signal multiple myeloma or metastasis, while abdominal or back pain may relate to gastrointestinal cancers. Persistent headaches, joint pain, or chest discomfort should also be evaluated if they don’t resolve over time.
6. Changes in Bowel or Bladder Habits
Noticeable changes in bowel or bladder habits can signal problems. Examples include:
-
Persistent constipation, diarrhea, or changes in stool color or size (possible colorectal cancer)
-
Difficulty urinating or blood in urine (possible bladder or prostate cancer)
These symptoms are often subtle at first, but when they persist, they can indicate a need for further investigation.
7. Lumps or Swelling
A lump or swelling in the body should always be examined, even if it isn’t painful. Common locations include:
-
Breasts (breast cancer)
-
Neck or armpit (lymph node enlargement)
-
Testicles (testicular cancer)
While many lumps are benign, persistent, growing, or hard lumps require professional evaluation to rule out cancer.
