Large bowel cancer – symptoms – when should I consult a physician?

One of the problems of large bowel cancer represents the fact that characteristic early symptoms are inexistent. Clinical symptoms usually evelop when the tumor is already in an advanced stage. For this reason preventative (screening) examinations of the colon are so important (see below).

Local symptoms in large bowel cancer:

  • Blood traces in the stool
  • Persistent changes of bowel habits (diarrhoea / constipation)
  • Abdominal pain, mostly in the form of colics
  • Obstruction of the intestine (ileus)

Unspecific symptoms in case of large bowel cancer:

  • Weight loss
  • Loss of activity
  • Symptoms of blood loss (anemia): paleness, loss of physical
    strength, rapid pulse rate despite only minor physical efforts.

If these symptoms occur, then you should urgently consult a
physician. It would be preferable, however, not to let it come so far
and actively perform a preventative colon examination.
