Cancerous polyps may cause no symptoms at all. But if you do have symptoms, they depend on where the polyp is located: Colorectal polyps may cause belly pain, constipation, diarrhea or blood in your poop. Stomach polyps may cause nausea, belly pain, vomiting and bleeding.
If a polyp has cancerous cells, they will also biopsy nearby lymph nodes to determine if the cancer has spread or metastasized to other areas of the body. In this case radiation, chemotherapy or other therapies may be recommended. Colonoscopy screenings can be life saving!
Because of this, it's important to keep up with colon cancer screening. Some people with colon polyps may experience these symptoms. Pain. Large polyps can obstruct the bowel and cause abdominal pain or cramping.
Ninety percent of cases occur after age 50, with males somewhat more likely to develop polyps than females; therefore, colon cancer screening is usually recommended starting at age 50 for both sexes. It takes approximately 10 years for a small polyp to develop into cancer.
A gastroenterologist, the specialist who usually performs a colonoscopy, can't tell for certain if a colon polyp is precancerous or cancerous until it's removed and examined under a microscope.
If your doctor finds precancerous polyps, there is no need for any additional treatment as long as they remove the entire polyp. Removing the tissue stops the development of cancer.
They look like bumps growing from the inside lining of the bowel protruding out. They sometimes grow on a “stalk” and look like mushrooms. Some polyps can be flat. People can have several polyps scattered in different parts of the colon.
People who have had certain types of polyps removed during a colonoscopy. Most of these people will need to get a colonoscopy again after 3 years, but some people might need to get one earlier (or later) than 3 years, depending on the type, size, and number of polyps.
Polyps in the colon or rectum
Some types of polyps can change into cancer over time (usually many years), but not all polyps become cancer. The chance of a polyp turning into cancer depends on the type of polyp it is. There are different types of polyps.
However, some larger polyps can cause: a small amount of rectal bleeding (blood in your stool) mucus to be produced when you open your bowels. diarrhoea or constipation.
But some larger polyps can cause: a small amount of slime (mucus) or blood in your poo (rectal bleeding) diarrhoea or constipation. pain in your tummy (abdominal pain)
Fatigue can happen if polyps or tumors bleed into the digestive tract, leading to a loss of iron over time and possibly iron-deficiency anemia. A direct side effect of iron-deficiency anemia is that individuals to feel tired and short of breath.
They are not cancer, and most of them have not started to change into cancer. If you get them at the precancerous phase, they don't have a chance to grow and turn into cancer. But you will need to come back for follow-up testing to see if more polyps turn up in the future.
If a doctor discovers polyps, they will often remove them via a colonoscopy or laparoscopy. The doctor will then send any removed polyps to a pathologist for a biopsy to see if cancer is present. If the biopsy reveals that cancer is present, then cancer specialists will outline a treatment plan for the person.
You should be screened regularly for polyps if: You're age 50 or older. You have risk factors, such as a family history of colon cancer. Some high-risk individuals should begin regular screening much earlier than age 50.
If polyps are found and removed during a colonoscopy procedure, the recovery period will be slightly longer. After polyps are removed it can take up to a week for the patient to fully recover. During this time, patients should avoid all strenuous activities, which includes lifting anything over five pounds.
While the majority of colon cancers start as polyps, only 5-10% of all polyps will become cancerous.
"Precancerous polyps are extremely common," he says. "We expect to find them in more than a quarter of the colonoscopies that we do at a minimum. So, you know, maybe a third or even a half of all patients getting [a] colonoscopy will have precancerous polyps."
Rectal bleeding is the most obvious colon cancer symptom, but there are other, more subtle signs, like learning you're anemic. It may be the first sign that you're bleeding internally. Other signs are you can't catch your breath, you feel bloated or crampy and you have severe constipation.
But only removal for examination under a microscope by a pathologist can accurately determine if a polyp is precancerous.
Most polyps do not cause symptoms. When they do, the most common symptom is bleeding from the rectum. A large polyp may cause cramps, abdominal pain, obstruction, or intussusception.
In most cases this can be done by removing the polyp or taking out the area with cancer through a colonoscope (local excision). Removing part of the colon (partial colectomy) may be needed if a cancer is too big to be removed by local excision.
