    Frequently Asked Questions

    Cancer that originates in the colon or rectum is called colorectal cancer, colon cancer, or rectal cancer. The colon and rectum are parts of the large intestine. Although it can happen to anyone, older adults are typically inflicted with colorectal cancer.

    As with any cancer, it starts unthreatening. Small clusters of polyps (cells in the colon) are formed inside the colon. Over time, these clusters grow bigger and become cancerous, resulting in colorectal cancer. Not many symptoms appear on the formation of polyps' clusters. That's why for screening, frequent tests are suggested by specialists to make sure the cancer is detected on time and polyps clusters can be taken out.

    While there are many oncologists in the country, if you are looking for one of the best colorectal surgeons in India, you may consider consulting Dr Praveen Kammar.

    Because the polyps clusters start benign, they don't show too many symptoms at first. But here are specific symptoms that begin to appear as time goes on:

    • Sudden weight loss
    • Changes in passing stool or bowel movements
    • Black or dark brown stool indicating blood in it
    • Loose motion or diarrhoea and constipation
    • Rectal bleeding
    • Abdominal pain
    • Loss of appetite
    • Fatigue
    • Anaemia

    When your body shows any symptom along with anaemia (low haemoglobin, pale skin, shortness of breath and fatigue), it is often recommended to undergo the screening for colorectal cancer. Only about 40% of the patients are diagnosed in the early stages of this cancer.

    Studies show that 37% of patients reported blood in their stools, 34% had abdominal pain, and 23% had anaemia.

    Among the patients who got an immediate diagnosis, 57% had bowel congestion, 27% had inflamed stomach lining, and 18% had perforated rectum.

    A number of the symptoms, as mentioned earlier, are pretty general. So consultation with a medical professional is highly advisable and very urgent in some instances. In such cases, you may consult with Dr Praveen, one of the top colorectal surgeons in India.

    Every cancer has five stages ranging from mild or acute to severe or life-threatening to incurable. It depends on how much cancer has spread around the body. Has it spread out of the original organ? Has it reached any other major organ? Factoring in various things, colorectal cancer has the following stages,

    Stage 0: Stage 0 means that colorectal cancer hasn't yet spread outside the innermost layer of the colon (mucosa). Stage 0 can be cured by removing the affected tissues by colonoscopy.

    Stage 1: In stage 1, cancer spreads outside the innermost layer to the next layer of the colon (submucosa), but not yet to the lymph nodes. About 90% of the patients diagnosed with stage 1 are cured by surgery alone.

    Stage 2: In stage 2, cancer spreads outside the submucosa. There are three substages in Stage 2 colorectal cancer:

    • Stage 2A: Although it has grown outside the submucosa, cancer has not yet reached the lymph nodes.
    • Stage 2B: Cancer has reached the membrane that holds the abdominal organs in place (visceral peritoneum). But it still hasn't reached the lymph nodes.
    • Stage 2C: Cancer has spread throughout the outer layer of the colon but still hasn't reached the lymph nodes.

    Stage 2 colorectal cancer has a survival rate of 55% to 80% (curable by surgery).

    Stage 3: Stage 3 is further classified into three categories:

    • Stage 3A: Cancer has spread through the muscular layer of the colon to the lymph nodes. But they haven't yet spread to the nearby organs.
    • Stage 3B: It has spread through 1 to 3 lymph nodes but not to the nearby organs.
    • Stage 3C: Cancer has spread to more than four lymph nodes but not to the nearby organs.

    Stage 3 colon cancer patients have a 40% chance of being cured and surviving. The patients go through chemotherapy after the surgery.

    Stage 4: Stage 4 is categorized into two categories:

    • Stage 4A: Stage 4A indicates that cancer has spread to one of the nearby organs like the lungs or liver.
    • Stage 4B: If cancer has spread to more than two or several nearby organs, it is in stage 4B

    Stage 4 patients can be cured about 14% of the time. Colorectal surgeons classify a patient to a particular stage after diagnosis and observe the body's symptoms and reactions. So it is necessary to visit a doctor before you speculate. You may consider scheduling an appointment with Dr Praveen, one of the best colorectal surgeons in India.

    After being diagnosed with any kind of cancer, it is understandable that you have certain queries and doubts as a patient. When looking for a colon cancer specialist in India, answers to the questions about cancer, its treatments and surgeries, and the patient's health help you make certain crucial decisions. Here are some of the most vital questions to make an informed decision:

    What stage is your colorectal cancer in?

    Like every other kind of cancer, colorectal cancer has five stages: stage 0 or mild to stage 4 or severe. Stage 0 indicates that cancer has not spread outside the innermost layer of the colon. Stage 4, however, signifies that cancer has spread through the colon to the lymph nodes and, most importantly, to the nearby organs like lungs, liver, etc. Stage 4 says that the cancer is metastasized. The staging of colorectal cancer also helps the doctor and the patient determine the survival chances.

    What does it mean that my colorectal cancer has metastasized?

    Metastasis is the process of cancer spreading to organs other than the origination point. Colorectal cancer is one of the cancers that can spread from the origin to other major organs of the body, especially to the liver. It can also spread to your bones, lungs, lymph nodes and, in the worst cases, to the nervous system. Cancer in its metastasized state requires urgent surgery, chemotherapy and other therapies, all simultaneously. It is vital to note that Metastasized cancer is not the same as recurrent cancer (which returns to the same part of the body again and again).

    What kinds of tests do I need?

    It is hard to diagnose this cancer in its earlier stages since its symptoms are very vague unless you appear to have anaemia along with other symptoms. There are several tests to determine the cancer type, its stage and the necessary treatments. For diagnosis, the doctors may perform a CT scan, MRI, ultrasound and colonoscopy, through which they can detect any abnormalities in the colon or rectum. To determine the precise treatment for a specific patient, an oncologist might do genomic testing of your cancer DNA for any mutations.

    How will colorectal cancer affect my quality of life?

    A patient's daily routine or what he can or cannot do, depends a lot on when the cancer was diagnosed (stage of cancer), what symptoms are appearing in the body, what treatment has the patient been prescribed, and how is it reacting with the body. It also depends on the other therapies being given to the patient. Treatments for colorectal cancer in its early stages have long-term effects. Medicines and treatments in any kind of cancer affect a patient's life drastically as there might be side effects. A colostomy is also required in some instances to allow the colon to heal after the surgery.

    Asking these questions is very important to make crucial and informed decisions. For any queries or consultation, you may call or visit Dr Praveen Kammar. He is one of the best doctor for colon cancer in India.
