What is polyp? Why is polyp easy to become cancer

Polyp, in fact, is a piece of redundant 'meat', or redundant 'meat'. On the inner surface of your internal cavity organs covered by mucous membrane, from the nasal cavity, vocal cord, gastrointestinal tract, gallbladder to uterus and bladder, are all places where you like to grow, which is called "multiple polyps". Now let's understand what polyps are? Why is polyp easy to become cancer

generally speaking, I grow slowly and stealthily, so I won't expose myself easily.

The polyp of vocal cord is the most easily exposed one among us. When it is small, such as sesame or mung bean, it makes people hoarse and is detected as early as possible;

When the polyp in the nasal cavity grows to the size of pea, the symptoms such as nasal obstruction and epistaxis will appear and the doctor will see it;

Children's rectal polyp, because easy to bleed and come out of the anus and show 'horse foot';

The polyp on the stomach body can grow very big and the patient has no feeling;

The most insidious is the colorectal polyp, which is often distributed in multiple places. It grows stealthily at ordinary times. When it changes, it will become colon cancer. But my surface is very fragile and easy to bleed. When the patient finds blood, he will go to see a doctor. My fox tail can't hide, but the patient's condition is not light.

So don't wait for symptoms to think of me!

you see, I'm in a lot of trouble. It's not a big deal. What people are most afraid of is my canceration, because canceration is carried out secretly. Once symptoms are found, it is likely that it has become terminal cancer, with extensive metastasis. At this time, the doctor is helpless for me. It's appropriate to say that I'm a close relative of cancer. But not all members of our family will become cancer. Here I can tell you some secrets. For example, 95% of colorectal cancer is what we look like when we grow up!

Because after all, the malignant ones account for a very small number, while the benign ones account for the vast majority. In general, they will not cause a threat to life. Even if the cancer changes, it will take a long time.

1. Polyps with rapid growth in a short period of time are often more dangerous and less auspicious. We should be alert to their canceration, especially those with a diameter of more than 2cm, which should be treated as malignant;

2. Polyps with histology of adenoma type are prone to canceration, while those with inflammation type are less malignant;

3. The polyps with small volume and pedicle are mostly benign, and are not easy to be cancerous, so patients do not need to be nervous. But the polyp with broad base and broad pedicle is often difficult to be safe and easy to be cancerous.

4. Some polyps with genetic tendency, such as familial colonic polyps, are prone to cancer;

5. The probability of multiple polyps canceration is increased. For example, if the canceration rate of one polyp is 1%, the canceration rate of 100 polyps may be close to 100%.

Since people know that we are related to cancer, people are more and more alert to our polyps. We can use nose, laryngoscope, cystoscope, esophagoscope, gastroscope, choledochoscope, colonoscope and so on to peep at our existence, treat us as precancerous lesions and deal with them thoroughly and timely, so that we have less and less chance to threaten patients' lives.

It will take 5-15 years for me to become cancer. If you can find me and cut me off in this period, I will never have a chance to become cancer again.

After you are 40 years old, I may grow into cancer. So, you should find me before I grow up and check me before I am 40 years old.

If you don't find me in such a long time, then I can grow into a cancer smoothly.

Since I am related to cancer, you can't treat me as a precancerous disease. You should operate in time to avoid the development of cancer.

With the development of medical technology, it has been able to cut off with a snare under the endoscope, or to treat with electric cauterization and laser, which is safe, effective, less painful for patients, and no longer requires thoracotomy, laparotomy, or even hospitalization.

But for those with a wide range and a large volume, it is difficult to resect under endoscope, and they still need surgical treatment in exchange for "temporary pain" for "long-term stability".

My vitality is extremely strong. Although you cut me off, your living habits have not changed, your internal environment has not changed, the soil suitable for my growth is still there, and I will take root and sprout, and revive!

So, even if you cut me, you have to check it regularly. Take colorectal polyps as an example:

① In clinic, the time of reexamination is usually determined according to the pathological results of colonoscopy, the integrity of resection, intestinal preparation, health status, family history of polyp and previous history;

② The time of reexamination after low and medium risk polypectomy is shorter than that in Europe and America, and it is suggested to be within 1-3 years;

③ It is recommended to reexamine the colonoscopy in a short period of 3-6 months in case of the following conditions:

The bowel preparation was not good enough to achieve high quality;

Microscopy failed to reach the ileocecal part and failed to complete the examination;

Colon cancer could not be examined by whole colon examination because of intestinal stenosis before operation;

More than 10 polyps were removed at one time;

Polyps larger than 1 cm were excised in segments;

More than 1 cm villus polyp with severe dysplasia;

When the polyp has been locally cancerous and does not reach the submucosa or exceeds the mucosa, it is not willing to be resected.
