Don't take it lightly! Many people delay these 6 minor illnesses and develop cancer...

Cancer does not develop overnight; it is a long process. Many cancers have precancerous conditions, and some benign lesions are actually the "prelude" to malignant tumors. If they are not taken seriously and allowed to develop, they may develop into cancer.

If minor illnesses are not treated, they may turn into major illnesses. One of the major illnesses is malignant tumors. If the following minor illnesses are not taken seriously, they may turn into cancer.

1. Chronic Inflammation

① Reflux esophagitis increases the risk of esophageal cancer.

②Chronic atrophic gastritis has the risk of developing into gastric cancer.

③ Chronic ulcerative colitis (it is estimated that 3% to 5% of patients with ulcerative colitis will develop colorectal cancer. With a history of ulcerative colitis of 20 years, 12.5% ​​will develop cancer, and the rate reaches 40% after 30 years).

④ Chronic hepatitis. Viral hepatitis (mainly chronic hepatitis B and hepatitis C) is the main risk factor for primary hepatocellular carcinoma. Other alcoholic hepatitis and drug-induced hepatitis are also risk factors.

⑤ Chronic pancreatitis can damage the pancreatic parenchyma, and repeated occurrence can increase the incidence of pancreatic cancer.

⑥ Chronic inflammation of the biliary system is a risk factor for gallbladder cancer and cholangiocarcinoma. 22% of patients with magnetic gallbladder caused by long-term chronic cholecystitis have gallbladder cancer. In Western countries, primary sclerosing cholangitis is the most important risk factor for cholangiocarcinoma, and 8% to 40% of patients with primary sclerosing cholangitis have cholangiocarcinoma.

⑦ Bladder infection (parasitic, bacterial, fungal or viral infection) may increase the risk of bladder cancer.

⑧ Chronic inflammation of the prostate can lead to excessive cell proliferation to repair diseased tissues, which can easily lead to infection-related cancers. Epidemiological studies have shown that patients with a history of sexually transmitted diseases or prostatitis have a significantly increased risk of prostate cancer.

⑨Chronic inflammation of the foreskin and glans penis is a risk factor for penile cancer.

2. Chronic obstructive pulmonary disease

Studies have shown that the incidence of lung cancer in people with chronic bronchitis is almost twice as high as that in people without chronic bronchitis. Other diseases such as a history of tuberculosis, pneumonia, and aspiration are also associated with lung cancer.

3. Gastrointestinal polyps

About 15% to 40% of colon cancers originate from multiple colon polyps, and the precancerous course is about 5 to 20 years. Adenomas can become cancerous, and the canceration rate for those with a diameter less than 1 cm is less than 2%, while the canceration rate for those with a diameter greater than 3 cm is more than 40%. For patients with familial adenomatous polyposis (FAP), the malignant transformation rate is 9.4% at the age of 25, 50% at the age of 30, and almost 100% before the age of 50, with a median age of 36.

4. Stones

Bile duct stones and gallbladder stones are one of the main risk factors for cholangiocarcinoma and gallbladder cancer. There is a strong correlation between gallbladder stones and gallbladder cancer. 75% of gallbladder cancer patients have gallbladder stones. For patients with gallstones with a diameter of more than 3 cm, the risk of gallbladder cancer increases 10 times.

Bladder stones may increase your risk of bladder cancer.

5. Leukoplakia

Leukoplakia or erythema of the oral mucosa is a risk factor for oral cancer.

Vulvar leukoplakia may be a risk factor for vulvar cancer.

6. Ulcerative lesions

Gastric and duodenal ulcers may develop into gastric cancer. If oral ulcers do not heal for a long time, you should be alert to oral cancer. If ulcers in any part of the body do not heal for a long time, you should be alert.
