Colorectal Cancer

It is the cancer that occurs in the large intestine. Colon cancer refers to the cancer associated with colon, the longest part of the large intestine. Cervical cancer grows in the rectum, the last straight part of the large intestine that ends in the anus. Explicit cancer is more common in men than women. The majority of patients with advanced cancer are over 60 years of age at the time of diagnosis, and colorectal cancer under the age of 40 is rare, says the best colon cancer doctor in Kolkata.

The main risk factors for the Colon and Rectum Cancer are:
  • Aging: the risk of developing genital cancer increases as a person grows older.
  • Risk factors associated with lifestyle
  • Diet: food is a very important factor in the natural risk of colorectal cancer. Foods that are high in red meat and processed, high-fat and / or low-fiber foods may increase the risk
  • Heavy drinking
  • Obesity
  • A sedentary lifestyle
  • Smoking
  • Type 2 diabetes increases the risk of developing a large intestine tumor.
  • Previous history of polyps in colon and rectum
  • Previous history of cancer in the colon and rectum
  • Inflammatory bowel diseases like Crohn’s disease or ulcerative colitis
  • Family history: about 20% of colorectal cancer occurs in a family setting

What our patients say

Colorectal cancer often causes complaints once it has progressed. According to the best colorectal surgeon in Kolkata, common symptoms are changes in bowel habits, abdominal discomfort, fatigue, weight loss. Blood in houses can be a warning sign. It can be seen with the naked eye or with laboratory analysis of chairs.

Endoscopy is a test in which a light tube inserted through the anus is inserted into the intestine. Allows to see the inside of the intestines. When the tumor is found within 15 cm of the anus, it is considered a rectal tumor, far from being considered a colon tumor.

Special radiation testing also helps to visualize the formation and size of the cancerous growth. Blood tests requiring carcinoembryogenic antigen (CEA), a tumor marker, may be helpful in selected cases. Confirmation of diagnosis is only given by laboratory analysis of the affected tissue and tissue (histopathology).

Colorectal Cancer Treatment Options in Kolkata:

Treatment planning involves a multidisciplinary team of medical staff. This usually refers to a meeting of different experts, called for different ideas. Treatment usually includes treatments:

  • Take action with your local cancer, such as surgery or radiotherapy
  • It acts on cancer cells systemically (throughout the body) as chemotherapy and targeted biological treatment.
  • The duration of treatment will depend on the stage of the cancer, the tumor structures and the patient’s risk.

Surgery:

The surgery is intended to remove the original tumor. In patients with advanced disease, surgery may also be performed to remove metastatic lesions. Regular sales are now considered more appropriate than class reductions in the treatment of colon cancer. Depending on the location of the tumor, such limited removal involves removal of an ascending colon (right hemicolectomy ) or descending colon (left hemicolectomy) or sigmoid colon (sigmoid resection). Right and left hemicolectomy is sometimes extended to a flexible colon and is called an extended hemicolectomy (right or left). The corresponding part of the intestines is removed along with the regional lymph nodes and any part of the nearby organs affected by the tumor. In the case of cervical cancer the entire rectum, and the mesorectum containing the regional lymph node is removed, the procedure is called total mesorectal excision (TME).

Reconstructive surgery can be performed by laparotomy, but also by laparoscopy. Laparotomy refers to open surgery, which means that the surgeon has a large incision in the abdomen to perform the operation. During laparoscopy, fine tubes and blisters are inserted through three or 4 holes in the abdomen. After laparoscopy, patients experience a quick and easy recovery after laparotomy.
