Cancer of the colon is one of the most frequently diagnosed cancer types, the symptoms of which can be manifested in different ways. Listed below are the most widely reported symptoms of the disease, which should never be overlooked. So, if you notice any of them, there is no time to wait. This does not necessarily mean that you have cancer, because the symptoms may be associated with other diseases. However, it is better to undergo a series of tests to find out whether you need medical help or not. Thus, the most common colon cancer symptoms include:
- Bleeding from the rectum and blood in the stool or on the underwear (by the way, many people mistakenly tend to associate these symptoms with hemorrhoids and lose precious time required to save their lives)
- Terry or black stool, which is observed on a regular basis (the thing is that blood in the stool may not be that obvious and if the tumor is located in the distant parts of the colon, the blood may be digested, thus causing the black color of the stool)
- Low hemoglobin levels in the blood, which is the sign of constant hidden bleeding in the organism
- Fatigue, loss of consciousness, recurrent dizziness, persistent weight loss
- Diarrhea, constipation or the feeling of insufficient bowel movement
- Bowel obstruction, which mostly develops, when the tumor is large enough not to allow proper colon functioning. These situations just cannot be left unnoticed, because the condition of a patient gets worse with every passing day. The symptoms of bowel obstruction include repeated bloating, nausea, vomiting, fatigue, abdominal pain, enormously sticking belly (or parts of it), narrow or ribbon-like stool, change of the regular bowel movement process, the feeling of incomplete bowel evacuation etc.
Experts underline that the average duration of these symptoms lasts for about 2 weeks. This is the time needed to a person to understand that something bad is going on in the organism and seek medical help.
