Chapter 2: Bleeding and Digestive Changes That Shouldn't Be Ignored
Some cancer warning signs involve the digestive or reproductive systems. These symptoms can easily be mistaken for common problems such as hemorrhoids, menstrual irregularities, digestive upset, or hormonal changes.
That is exactly why persistent symptoms deserve attention.
4. Unusual Vaginal Bleeding
Unexpected vaginal bleeding can have many causes.
It may occur because of hormonal fluctuations, contraception, fibroids, polyps, infections, perimenopause, or other gynecological conditions. But abnormal bleeding can also be associated with cancers of the reproductive system, including cervical and endometrial cancer.
Particular attention should be paid to bleeding after menopause.
Any vaginal bleeding after menopause should be evaluated by a healthcare professional, even if it happens only once.
Women who experience bleeding between periods, unusually heavy periods, bleeding after sexual intercourse, or a significant change in their normal menstrual pattern should also discuss it with a healthcare professional.
The symptom does not mean cancer is present. It means the underlying cause should be determined.
5. Persistent Bloating or Abdominal Swelling
Bloating is extremely common. Certain foods, constipation, menstrual cycles, and digestive disorders can all cause temporary abdominal bloating.
The concern arises when bloating becomes persistent, frequent, progressively worse, or occurs alongside other symptoms.
Some gynecological cancers can cause abdominal swelling, pelvic discomfort, early fullness while eating, or changes in bowel and bladder habits.
Again, these symptoms are not specific to cancer.
A woman experiencing persistent bloating should not immediately assume she has ovarian cancer. Instead, she should consider whether the symptom is new and whether it continues despite normal dietary or lifestyle changes.
6. Persistent Changes in Bowel Habits
Long-lasting diarrhea, constipation, changes in stool caliber, or a persistent feeling that the bowel has not completely emptied can have many causes.
Diet, medications, irritable bowel syndrome, infections, inflammatory bowel disease, and other digestive conditions can all alter bowel habits.
However, persistent bowel changes—especially when accompanied by blood in the stool, unexplained weight loss, abdominal pain, or anemia—should be assessed.
Colorectal cancer is one reason doctors may investigate these symptoms, particularly in people who are at increased risk or are within recommended screening age ranges.
