What is cancer of the colon symptoms?

My wife suffers from severe constipation for more than a month and a half, and weighing less significantly and without apparent reason, and you feel tired, but not always, also complaining about the large number of gases, and sometimes I have said on the feces accompanied with mucus,I read about cancer of the colon symptoms and found it applies to some extent, are there other diseases apply the above symptoms?

Another question:
I had asked you before about the problem my wife is summarized in the following:

My wife started a program LOSS (leaving dinner in whole) after the doctor advised her that it was suffering from pains in the back, then after that pregnancy has occurred and is now in its third month.

Before Ramadan began in the district of former fast in spite of the symptoms of pregnancy because she was vomiting so much and for 15 days was fast and deal with only one bread per day, and after the holy month of fasting which continued to suffer from nausea and vomiting.

With constipation gradually began to fast the first to become chronic, and began to decrease weight and clearly (lost about 9 kg of weight).

Two days after the feast we have conducted a test of the stool and the presence of blood turned out to note that there is no trace of blood with the naked eye.

Advised the doctor's work perspective and perhaps doubt in the presence of cancer of the colon symptoms, God forbid, then eased constipation, and is now for three days excreted almost normal; where she has no difficulty in the output, and increased the amount of stool outside and thick, and the fatigue and fatigue subsided also became involved in the events without feeling very tired as before.

My question is: Do you still have to do the work of the telescope necessary? Is it still the possibility of cancer exists?

Please advice.
Answer
In the name of God the Merciful
Mr. Brother / Mubarak, May Allah protect him.
Peace be on you and God's mercy and blessings be on you,

For the first question:

In such cases of constipation the new as well as associated symptoms such as weight loss, and fatigue, especially if any blood in the stool, whether analyzing stool for blood or seeing blood, these symptoms require a medical examination, has resorted doctor for a telescope of the colon to make sure there are cancer of the colon symptoms.

Many causes of constipation, you know, it is associated with symptoms such as symptoms that complaining about your wife, the fatigue and weight loss, it is these reasons, for example, lack of activity of the thyroid gland, which are accompanied by constipation in the sense of cold, fatigue and lethargy.

And constipation caused by certain medications may be associated with him also a lack of appetite, and weight loss due to a lack of appetite, and may cause constipation when the patient's fear of eating, and therefore lack of weight, and because of lack of food the patient feels tired and fatigue, but be sure, and rule out the presence of tumor in the colon , especially if cancer of the colon symptoms persist, the first thing is being a medical examination, medical tests and then, the poverty found in the blood, and found blood in the stool analysis, then it must be done laparoscopic.

For the second question:

Then, the constipation may have several reasons, including vomiting, lack of food, lack of fluids and vegetables in the food, and may be feeling tired and fatigue due to not eating enough food.

But what is worrying is the presence of blood in the stool analysis of feces, it was sure of it again and again, it must know the cause of the blood, and here it must be noted that if she was eating iron tablets can cause constipation, and may cause that the analysis of blood stool positive false because of the iron.

And sometimes also cause the meat to be in the stool blood test is positive, also
Of the reasons for the presence of blood in the stool is a real anal hemorrhoids associated with constipation, and sometimes be caused by growths in the rectum to the diet or cancer of the colon symptoms.

In such case your wife can be re-analyze the stool again and again (each 24 hours) after you stop taking iron pills that were dealt with, and stop eating meat for 48 hours, the result was negative both times, it can monitor the situation, control of symptoms, and patient, and the telescope does not work, especially since most of the symptoms that they complain of them have disappeared, and that fatigue and fatigue also disappeared, although they have regained the weight lost.

cancer of the colon symptoms must be repeated that the work of the telescope,We ask God to heal her soon.
