12. SIGNS & SYMPTOMS
Constipation is an important sign of cancer in the
colon. Highlights the link between constipation and
colorectal cancer risk It supported the hypothesis
that constipation or laxative use increases the risk
of colon cancer. A tumor present at the far end of the
colon can make it very difficult to eliminate waste
products, thereby causing constipation.

13. SIGNS & SYMPTOMS
If you suffer from diarrhea for more than a couple of
weeks, it may be an early symptom of colon cancer.
When a tumor partially obstructs the bowel, it can
cause alternating constipation and diarrhea due to
leakage of liquid stool. You may also experience
frequent gas, abdominal pain, nausea and vomiting.
Plus, a tumor may irritate or narrow the lining of the
intestine.

14. SIGNS & SYMPTOMS
Most often, blood in the stool is due to piles
(hemorrhoids), where the veins in the back
passage become fragile and cause a little
bleeding during a bowel movement. This type of
bleeding is generally red.

15. SIGNS & SYMPTOMS
If your abdomen, especially the lower part, hurts
or feels tender when touched, this can be an
early indication of tumor growth in the digestive
tract, colon or rectum. A tumor can cause a
block in the colon, restricting blood flow. This
leads to abdominal pain that can be severe.
This pain also can indicate that the cancer has
begun to spread to other organs.

16. SIGNS & SYMPTOMS
Anemia refers to a low red blood cell count in the body.
The hemoglobin in red blood cells carries oxygen
throughout the body, a fast or irregular heartbeat,
shortness of breath, dizziness, and cold hands and
feet, should not be taken lightly. Unexplained anemia
may be due to colon cancer. Typically, cancer in the
right-side of the colon causes iron-deficiency
anemia. This happens when tumors start bleeding
slowly into the digestive tract, causing blood loss
over time.o add text

weakness and general malaise. Fatigue and
