Colon cancerous affection is the number two cause of death worldwide, and the first in cancerous diseases. This is called a killer disease because it affects a large segment of the population, especially men, with a death rate of fifty two thousand sufferers per year. This is basically one third of the actual number of existing sufferers.

The reason for the apparition of colorectal diseases is still a mystery and unfortunately so is the therapy for it. Many people tend to acquire this affection and as we mentioned above, one third of the cases end up with death. The evolution of colon or rectal cancer is measured through its stages. The first two are virtually unnoticeable because it has no strong indications or particular symptomatic states that can show you that something is wrong.

The last stages are marked by the combination of the symptoms that occurs during the aggressive development of colorectal diseases. Some of the felt symptomatic states are directly linked with abdominal pains and digestive or excretive troubles. Abdominal pains are the most common things, along with time periods with constipation or diarrhea, or just an alternative diarrhea and constipation.

Other troubles that might indicate a first or second stage of development for the colon cancer is the overall tired sensation, lack of appetite and some pains while eliminating the stool

The stool itself can suffer from some color changes and even though is not an accurate indicator in the vast majority of cases melena is a certain indicator. This problematic issue is happening when the stool is eliminated and it has a darker color, very close to the black nuance. This is because of the internal colon lesions that may bleed occasionally and cause the stool to form with a bloody content inside. The digestive problems may also progress in this way but in sixty percent of the cases a colon lesion is discovered.

Colon cancer is identified more easily in its last stages, where the symptoms are more pronounced and they also become the effects. The pains start to intensify and spread from the abdominal area to the rectal region. The whole excretion apparatus becomes a painful area and the stool problems intensify, regardless of the fact that what is eliminated come out as a diarrhea, constipation, or just a darker stool.

The worldwide medical communities are still continuing with ongoing efforts to find a proper treatment that can cure a sufferer even though he reached a final stage of its development.

This cancerous affection is very hard to proper diagnose and in many of the cases the first two stages pass on without the individual to notice anything wrong. Being later detected means a much lower rate in finding the right and proficient treatment for it. So in many of the cases, prevention is the key, as in every other disease.
