The three words I don't want to hear in life
Cancer! Cancer! Cancer!
however
Cancer doesn't come out of nowhere
It is a slow process
Progression from "precancerous lesions" to cancer
It usually takes years or even decades
If it is "precancerous", it can be stopped
Timely "brake" intervention
Then cancer will be difficult to pester
1
Chronic atrophic gastritis
Stomach cancer "precancerous lesions"
The symptoms of chronic atrophic gastritis are not pronounced and have no specificity
.
The general course of development of stomach cancer
Chronic atrophic gastritis: the gastric mucosa ages with age, and older gastritis is dominated by
chronic atrophic gastritis.
Intestinal epithelial metaplasia and dysplasia : gastritis occurs repeatedly, the gastric mucosa is repeatedly damaged and repaired, and as a result, cells that should be found in the intestine grow in the stomach, and "intestinal epithelial metaplasia"
appears.
Dysplasia, which is considered to be the closest state to gastric cancer, is between cancerous and non-cancerous, and requires close monitoring and, if necessary, endoscopic resection of the lesion
.
Methods of intervention
1 Examination It is recommended to check the gastroscopy of superficial gastritis every 3 years, and chronic atrophic gastritis to check the gastroscope every 1 to 2 years, and actively treat.
2 Cessation of smoking and alcohol The severity of atrophic gastritis is positively related to
smoking and alcohol consumption.
3 Regular diet Diet should chew slowly and swallow, eat less pickled foods, do not overeat, and do not eat spicy moldy foods
.
2 adenomatous intestinal polyps
Bowel cancer "precancerous lesions"
Adenomatous polyps are recognized as precancerous lesions, especially those larger than 2 cm in diameter, with a higher
chance of becoming cancerous.
Not all intestinal polyps become cancerous
.
In general, intestinal polyps are divided into two categories
: non-tumor polyps and adenomatous polyps.
Non-adenomatous polyps, such as inflammatory polyps and proliferative polyps, have little
to do with the incidence of bowel cancer.
Methods of intervention
1 Check people over 45 years old, high-risk people for colonoscopy, everyone should not refuse to have a digital examination
once a year.
2 Adjust the diet Heavy drinking, smoking, genetic mutations, the incidence of intestinal polyps will also increase
.
3 Pay attention to stool signals When there is a black stool, blood in the stool, or repeated diarrhea/constipation, the body has alerted us, please consult a doctor
as soon as possible.
3 pulmonary nodules: atypical adenomatous hyperplasia
Lung cancer "precancerous lesions"
Lung nodules may simply be inflammation, or they may be manifestations of
tuberculosis or tumors.
Fortunately, most of the nodules are benign and don't worry too much, only a few need to be wary of cancer.
The more "eccentric" the nodule grows, the greater
the malignancy is likely to be.
For example, there are lobes, burrs, pleural traction, bronchiole and small vesicle signs, eccentric thick-walled cavities, etc
.
In addition, look at the size of the nodule, > 1.
5 cm solid nodule or > 8 mm mixed frosted glass nodules, which are high-risk nodules; nodules less than 0.
5 cm, the possibility of malignancy is very small
.
Methods of intervention
1 Examination If there are risk factors such as smoking and family history, it is recommended to do low-dose spiral CT screening for early lung cancer
in people older than 40 years of age.
2 Quit smoking The incidence of lung cancer in smokers is 10 times that of non-smokers, and quitting smoking can significantly reduce the incidence of
lung cancer.
3 Pay attention to indoor ventilation to prevent indoor micro-ambient air pollution, pay attention to maintain indoor ventilation, improve indoor air quality
.
4 Reduce kitchen fumes Cooking minimizes frying, frying
.
Before stir-frying, open the window and open the range hood, and after stir-frying, the range hood should be opened for another 5-10 minutes
.
4Atypical hyperplasia of the mammary gland
Breast cancer "precancerous lesions"
First of all, we must give everyone a reassuring pill, simple breast hyperplasia, is a "disease" with almost no harm, and it can even be said that it is not a disease, nor will it become cancerous
.
Only a pathological diagnosis of atypical hyperplasia of the breast may be a precancerous lesion
of breast cancer.
Methods of intervention
1 Examination Women aged 25-40 years do a breast examination and ultrasound
every year.
Women over the age of 40 are routinely undergoing a mammography examination, a breast physical examination and a mammography ultrasound or mammography examination
every year.
2 Do not use estrogen health products Misuse of estrogen products can lead to hyperplasia of epithelial cells of the breast ducts, and even cancerous.
3 Eat less high-fat foods Eat less fried foods, cream, cheese and various sweets, control fat intake, and avoid obesity
.
4 Maintain a good mood Negative emotions can easily lead to secretion disorders in the body, which is related
to breast diseases.
5 Proper exercise is an important factor
in preventing breast cancer from occurring.
6 A natural birth is important If you decide to have children, having children before the age of 30 is more recommended, because progesterone has a great protective effect
on women.
7 Breastfeeding can reduce the incidence of breast cancer, and statistics show that breastfeeding in December can reduce the risk
of breast cancer by 4.
3%.
5 Cirrhosis
Liver cancer "precancerous lesions"
The evolution of liver cancer is generally through the hard transformation of the liver to the proliferation of atypical liver cells, and then evolve into liver cancer, which takes a long
time.
From cirrhosis, to the appearance of atypical hyperplasia of liver cells, to the development of liver cancer, it takes about 10-16 years
.
Liver cancer occurrence trilogy in China
To prevent liver cancer, the most important step is to prevent hepatitis! In China, about 60% of cirrhosis and 80% of liver cancer patients are caused
by hepatitis B virus infection.
Although liver cancer is not contagious, the cause of liver cancer, hepatitis B virus, can be transmitted through blood transfusions, sex, and mother-to-child transmission
.
The occurrence of cirrhosis is related to a variety of factors and requires a long-term process, so we should check our bodies regularly to prevent and detect cirrhosis
as early as possible.
Methods of intervention
1 Examination of patients with hepatitis B cirrhosis is best to have a physical examination every 3 months to half a year, mainly to check the liver B ultrasound and alpha-fetoprotein
.
2 Active treatment Patients with cirrhosis should receive standardized treatment in a timely manner, and hepatitis B should be actively treated for hepatitis
B.
3 Quit smoking and limit alcohol to avoid overwork
.
6 Cervical intraepithelial neoplasia lesions
Cervical cancer "precancerous lesions"
Cervical epithelial cells can change from atypical hyperplasia to cancer after persistent HPV infection, which can take up to 10 years or more
.
Among them, cervical intraepithelial neoplasia lesions, which are often referred to as cervical precancerous lesions, are divided into one, two and three levels, the higher the level, the more likely it is to become cancerous, and the lower the level, the better treatment
.
Be careful! A small amount of vaginal bleeding after a gynecological examination is contact bleeding, which may be a symptom
of cervical precancerous lesions and cervical cancer.
Methods of intervention
1 Examination Women who have sex should have TCT and HPV testing
once a year.
If abnormal is abnormal, colposcopy or biopsy
is required.
2 Active treatment of inflammation Active treatment of chronic cervicitis and cervical precancerous lesions
.
Sexual life should pay attention to hygiene
.
3 HPV vaccination Cervical cancer vaccine can be vaccinated to prevent cervical cancer from occurring
.
7 junction moles
Melanoma "precancerous lesions"
Junction moles are often long in the palms, plantar feet, vulva and other rub-prone areas, and have a high
possibility of carcinogenesis compared with other moles.
Once the shape of the mole is found to be irregular, the boundaries are blurred, the color is different, the halo appears or the volume slowly increases, and the skin appears slightly raised or thickened, it is necessary to consult a doctor
in time.
Methods of intervention
1 Chemical peeling or laser mole removal methods are more irritating, and it is not recommended to treat large junction nevi in this way
.
2 Avoid too much friction in life, for junction moles with red flags, it is best to use surgical resection plus pathological examination
.
