The colon or large intestine is medically divided into the right colon, the transverse colon, and extends into the abdomen crosswise from right to left, the left colon, and then the rectum.

types of colon tumors

1- Benign tumors are non-malignant tumors

2- Malignant tumors, i.e. cancerous tumors

Benign tumors, from their name, are tumors that are found in the colon and remain in the colon and do not spread outside the colon. They are slow to grow. They may be single, i.e. one tumor or multiple, and this multiple may be found in a number of members of the same family, meaning that it may exist between more than one generation in the same family and there is more than one type As some of them are accompanied by the presence of discoloration, i.e. an increase in the presence of melanin pigment in the lips and tongue, and the multiple tumors present in these patients are of different sizes and spread in the different parts of the colon, and some of them can turn into a cancerous tumor.

Symptoms of colon tumors

Patients with colon polyps suffer from the following:

1- Frequent and non-specific abdominal pain

2- Excretion, any stool that may be accompanied by blood

Diagnosis of benign colon tumors

1- The medical history, with a focus on the family history, if one of the family members had colon tumors.

2- Clinical examination, including examination of the lips, mouth, abdomen and anus

3- The laboratory examination, especially the examination of stool for visible and invisible blood, as well as the examination of tumor parameters

4- The endoscope, that is, colonoscopy, and we perform the endoscope for two purposes: a diagnostic goal, i.e. seeing and determining the location, size and number of tumors. The type that more than one family member has, tissue samples should be taken from more than one tumor to be examined in the laboratory, as well as colonoscopy for all family members. These tumors

Cancerous or malignant colon tumors

It is more prevalent among men than women, although there is a noticeable increase in the incidence of women. It is considered the second cancer that affects men after lung cancer. It is called carcinoma because it multiplies rapidly and spreads outside the colon in different ways through direct spread to neighboring organs, such as the system, lymph nodes, and all the blood.

colon cancer causes

1- Diseases that affect the colon, such as ulcerative colitis, crohns, and bubbles that are multiple

2- Multiple tumors found in some families

3- Eating a lot of red meat, especially beef

Symptoms or complaints of colon cancer patients

1- Frequent and prolonged abdominal pain

2- Weight loss and wasting

3- Loss of appetite

4- Increased constipation

5- The nature of the stool changes, as it becomes soft and hard

6- The exit of blood accompanying the stool

7- Bowel obstruction with vomiting and no stools or gases

Diagnosis of colon cancer

1- Medical history

2- family history

3- Laboratory examination of blood, tumor parameters and stool examination

4- Radiation such as ultrasound, color rays and CT scans

5- The endoscope for the whole colon and we do the endoscope and take tissues from the tumor for examination. The endoscope and taking the sample is decisive in diagnosing the cancerous tumor


As the sages said since ancient times, an ounce of prevention is better than a pound of cure. We must eat a balanced food that contains many vegetables and drink sufficient quantities of water. The patient should refer to the specialist doctor if symptoms recur with him. Also, family members who suffer from more than one family member should have endoscopy. For all family members, early detection of the tumor can lead to a full recovery

Types of treatment for colon cancer

1- Surgery, and the two goals of surgery are complete excision of the tumor and complete recovery, and this is possible in early cases.

2- Chemotherapy, which is complementary to surgery and aims to eliminate the spread of cancer cells

3- deep rays

As mentioned earlier, early detection of the disease leads to recovery
