Don’t Ignore these Signs and Symptoms of Colon Cancer
- Blood in stools
If you find blood on or mixed in with your stools, this could be a sign that you have colon cancer. Your doctor will send a stool sample for a laboratory analysis called a fecal occult blood test.
- Changes in stools
Stools are very dark in color, or even black and sticky, then this could be caused by bleeding due to colon cancer.
- Rectal bleeding
Blood is usually bright red and it can be found in the toilet bowl water or on toilet paper.
- Trouble passing stool
Changes in passing of stools is a symptom of colon cancer. You may experience a feeling of completely passing a stool or you may feel the urgent need to have a bowel movement, and then you realize that there is no stool to be passed.
Anemia is a shortage of red blood cells in the blood. It can happen from blood loss from colon cancer. Symptoms of anemia are feeling tired a lot of the time, weak and short of breath. Your skin may also look pale.
- Abdominal pain
A certain amount of abdominal discomfort is a normal experience at times. However, if you often suffer from gas, cramping and bloating, then you could be more likely to develop colon cancer.
- Weight loss
Even if you have a normal diet, colon cancer can result in weight loss. Alternatively, you may experience complete loss in appetite.
Constipation lasting more than a few days can be associated with colon cancer. Chronic or ongoing constipation may even increase your risk of developing colon cancer.
Persistent diarrhea is often symptom of a colon cancer.
