Hello everyone
I am your new "old" friend, old Man
Study the anorectum for most of your life
I always want to talk to you
Today's topic: Intestinal polyps, is it a prelude to cancer?
Let's start with the conclusion:
80% of colorectal cancers
Evolved from polyps[1]
Remember this sentence of the old man:
It needs to be highly valued, but don't be nervous
Changes in the body
It is the imprint of the passage of time
Intestinal polyps, a superfluous dangerous molecule
Simply put, it is a piece of excess "meat"
Its incidence, 40 years old, is a watershed
Under 40 years old: About 20% to 30%
Over 40 years old: 40% to 50% [2]
It is a small bulging mass
That is, 0.3 to 1 cm
When more than 1 cm
The risk of becoming cancerous increases
Nasal cavity, vocal cords, gastrointestinal tract, gallbladder, bladder, large intestine
These are all places where it may haunt
Among them, the large intestine polyp is the most insidious and cunning
Why?
Old Man, give you an analysis of its tactics
Tactic 1: Choose the "Terrain" to hide yourself
The large intestine is made up of two segments of the colon and rectum, like a gate
It is 1.5 meters long and meandering and wrinkled
Suitable for polyps hidden here
Tactic 2: Don't give you early warning signals, quietly become cancerous
With a petite figure and a unique growth position
Its presence leaves you completely indifferent
There is no suspicious phenomenon about the number, color, and frequency of poop
The enemy is in the dark and you are in the light
It grows slowly and happily
From polyps to cancer about 5 to 15 years[3]
Inadvertently
One day, the stool sent a warning:
The number of bowel movements increases, and there is a feeling of inexhaustibility
The shape is thinner, grooved and bloody
The closer you get to the anus, the brighter the color of the bloody stool
Stool with meat balls
In addition, there will be a feeling of bloating
Wait until you find an anomaly
It may have become cancerous
Strategy 1: Early detection, early treatment
01. Preventive examination:
The following conditions are met
Colonoscopy is recommended regardless of symptoms:
1. Be over 40 years old
2. The disease is present in the immediate family
02. Surgery:
Removal or excision in benign phases is recommended
Listen to the doctor for specific situations
Strategy 2: Diet prevention
Appropriately reduce high protein and high fat
Fry food, quit smoking, and drink less alcohol
Large intestinal polyps, more than one side
There are three kinds of images
There are two factions:
Benign, malignant
But what is benign can also become malignant
According to the pathological characteristics there are three factions:
Hyperplasia, inflammation, adenoma, see figure for details
Malignancy rate of adenomatous polyps[4]:
Diameter: less than 1 cm is about 1%.
Adenomatous polyps have 3 branches:
Tubular adenomas, villous adenomas, mixed adenomas
Finally, please remember that the registered department:
Gastroenterology, proctology, and general surgery are available
Be sure to clear the time bomb of bowel cancer as soon as possible
Everyone, love yourself
A long road of life
Let the enemy of disease come a little late
Many old masters will continue to work hard
Escort you
Well, that's it, what else do you want to know
Leave a message for the old man
