Thank you for the query.
Symptoms which can point to colon cancer
and narrow stools. Pimples on the stomach are rather not related to colon cancer.
You should be aware of colon cancer if you are older than 50, have had colon cancer in the family. If you are quite young person, colon cancer is rather unlikely.
Other symptoms of colon cancer are: weight lost, blood in stool
, nausea, vomiting, bloating, constipation and diarrhea alternately, weakness, low hemoglobin level.
Other diseases which can cause constipation are chronic bacterial infection, bad diet (lack of fiber rich products and mineral water intake), medicines (Ca-blockers, antidepresants), thyroid disease
I suggest you to visit your doctor and have some diagnostics performed. If you are around 50, colonoscopy should be done. If you are young person, FOBT (fecal occult blood test
) should be fine. Blood work, abdominal ultrasound, thyroid tests should be also done.
Hope this will help.
