Many people have minor illnesses and pains even if they do not have major illnesses. Some minor illnesses do not require medication and they will be fine after a while, but some illnesses cannot be delayed because they may become cancer after a long time. There are six kinds of minor diseases that are not fatal but can become cancer if left untreated for a long time 1. Mammary hyperplasia includes lobular hyperplasia, cystic hyperplasia and cystic dilation of milk ducts with papillary hyperplasia in the milk ducts. Generally speaking, if there is no symptom of lobular hyperplasia, it should be a physiological breast enlargement and can subside on its own without special treatment. However, if it is cystic hyperplasia, there is a risk of cancer. Cystic hyperplasia is a pathological change, and many symptoms are similar to breast cancer. According to statistics, those who have adenomatous hyperplasia and do not heal for a long time have about 20% chance of malignancy, and women with cystic hyperplasia are four times more likely to develop breast cancer than healthy people. Therefore, after a physical examination reveals breast enlargement, you should go to the hospital for further examination to confirm which type of breast enlargement it is. If you are suffering from cystic breast hyperplasia, you must have regular mammograms. Patients need to go to the hospital for review every 2-3 months for early detection and early treatment of possible breast cancer. How can I prevent breast pre-cystic hyperplasia? In order to reduce the incidence of this disease, from a “sexual” point of view, the following aspects can be started: (1) to marry and raise children at the right time. To promote late marriage and late childbirth, but not too late. It is best for women to get married at the age of 28 and give birth before the age of 30, too late birth is not conducive to eugenics. (2) To do a good job of contraception. Because the embryonic villi secretion of estrogen and progesterone at 6 weeks of pregnancy will stimulate breast hyperplasia. If you have an abortion, the enlarged breast tissue will not shrink easily and it will be more difficult to restore the original shape, which will easily form lobular hyperplasia. (3) Regularity in intercourse. The breast is not only a breastfeeding organ for women, but also a sexual organ. During sex, the breast will undergo cyclical changes: in the sexual excitement period, breast veins are engorged, breast enlargement, plump; sexual duration, areola engorged, nipple erection; orgasm, these changes also reached the peak; after orgasm, areola engorged quickly fade, a quarter of an hour after the enlarged breast gradually restored to its original state. These reactions of the breast are a regulation of the breast function. If there is a long-term lack of sexual activity, there will be a lack of this physiological regulation, it is easy to induce lobular hyperplasia and the occurrence of breast cancer. Therefore, couples should have a regular sexual life. (4) Breastfeeding is necessary. Breastfeeding can reduce the incidence of breast enlargement and breast cancer. 3. Thyroid nodules Thyroid nodules are lumps in the thyroid gland, the cause of which is related to gender, age, history of neck radiation exposure and other factors. In general, only 10% or less of thyroid nodules may be malignant, but treatment should not be ignored. The vast majority of benign thyroid nodules do not require treatment. Diagnostic treatment is only required when the nodule is greater than 5 mm in diameter, when the patient is under 30 years of age, when it is solitary, when it grows rapidly over a short period of time and when it compresses surrounding organs. In particular, it is important to note that a single thyroid nodule has a higher chance of being malignant, and it is even more important to seek prompt medical attention if a single thyroid nodule is found. The high incidence of thyroid nodules is closely related to factors such as poor lifestyle habits, mental tension and stress, as well as the increasingly advanced medical screening equipment that allows the disease to hide. Clinically, people with a history of neck X-ray exposure as a child and those with thyroid disease in their family are at high risk. This group is recommended to have an ultrasound of the thyroid gland added to the physical examination, and if there are no nodules, to be checked once a year. If a thyroid nodule is found, it should be rechecked once every 3 months to 6 months, or a direct fine needle aspiration. How to prevent thyroid nodules? Since the appearance of thyroid nodules is related to autoimmune ability, genetic factors, long-term excessive or insufficient iodine intake, radiation factors, and fast-paced and high-stress lifestyle. Therefore, prevention is also multifaceted, such as paying attention to a disciplined diet, regular work and rest, and being as emotionally calm and stable as possible to lay the foundation for your health and increased immunity. When going to the hospital for examination, pay attention to follow the doctor’s instructions for appropriate radiation protection. And once found to have thyroid disease should go to the hospital for active, regular treatment. 3.Gastrointestinal polyps Gastrointestinal polyps are mucosal bulge-like lesions formed by local mucosal hyperplasia and hypertrophy caused by chronic inflammation of the mucosa, mainly inflammatory polyps, adenomatous polyps, hyperplastic polyps, etc. In fact, many gastrointestinal cancers are evolved from polyps, and the larger the size of polyps, the higher the chance of cancer. Some surveys show that patients with colon polyps are 3-5 times more likely to develop colon cancer than the general population. Two things are clear about intestinal polyps: (1) clinically, about 90% of intestinal cancers evolve from polyps; (2) whether polyps are benign or malignant needs to be diagnosed through colonoscopy or surgery, biopsy or tissue specimens obtained by removing polyps, and pathological screening. “As far as we can see, multiple polyps have a higher chance of becoming cancerous than single ones; the more dense and numerous the adenomatous polyps are, the more likely they are to become cancerous; the older they are, the higher the chance of becoming cancerous.” Dr. Chen said, so, if found to have gastrointestinal polyps, must be timely treatment, should not be taken lightly. In addition, a high-fat diet; sedentary, lack of exercise; inadequate dietary fiber intake; irregular bowel movements or habitual constipation; smoking, alcohol and other poor lifestyles can also increase the risk of cancer. How to detect intestinal polyps at an early stage? It is recommended that patients over 45 years of age should have a regular colonoscopy, and if any discomfort in the intestinal tract occurs in their life, they should consult a specialist in time. 4, chronic ulcerative diseases Oral ulcers and gastric ulcers are very common “minor diseases”, many people often do not take them seriously, especially oral ulcers, may not even take medicine. However, we should pay attention to the fact that chronic ulcers may become cancerous if they exist for a long time. If the same mouth ulcer is not good for a long time (more than 1 month), it may be related to oral cancer, and if stomach ulcer is not treated in time and recurring, the possibility of cancer is also very high. Therefore, we should not think that ulcers are minor diseases and must be treated in time. (1) Mouth ulcers that are difficult to heal for a long time must be beware of the occurrence of oral cancer. Mouth ulcers are a common condition, and the duration of the disease usually does not exceed two weeks. If symptoms such as burning sensation and pain persist for more than two weeks without improvement, you should be extra alert. Because oral cancer often manifests itself in the form of ulcers with raised edges and uneven center, covered with necrotic tissue and obvious pain. In addition, the normal oral mucosa is pink, if mucosal erythema, edema and granular granules appear suddenly in the oral cavity, it means that the mucosal epidermal cells have changed. Especially white spots, it is considered precancerous lesion of oral cancer. (2) About 5% of gastric ulcers become cancerous, and there is an increasing trend in recent years. According to our literature, about 5% of gastric ulcers can become cancerous, and this number has a tendency to increase in recent years. If the patient has irregular episodes of pain or persistent vague pain, the effect of anti-ulcer medication is not obvious, repeated vomiting of blood, persistent black stool or tarry stool, or persistent positive fecal occult blood test, etc., he/she should go to the hospital for gastroscopy and pathological section examination in time. (3) Ulcerative colitis is more likely to become cancerous. Although ulcerative colitis is not a precancerous lesion, it is more closely related to cancer. Chronic ulcerative colitis is widely considered to be associated with an increased risk of malignancy. Although the number of patients dying from bowel cancer is gradually increasing every year, many patients with ulcerative colitis do not pay enough attention to it, thinking that they can get better with some anti-inflammatory drugs, treating the symptoms but not the root cause, which eventually leads to recurrent attacks from mild to severe, or even untreated for a long time, and eventually cancerous, leaving lifelong regrets. The combination of Chinese and Western medicine, especially the treatment methods such as Chinese intestinal therapy, can better control this disease, and the recurrence rate is relatively lower, so I hope that patients will pay great attention to it, so as not to drag the inflammation into cancer. 5, diabetes A study found that diabetic patients have a higher chance of developing breast cancer, endometrial cancer, pancreatic cancer, liver cancer, prostate cancer, colorectal cancer and other cancers than non-diabetic patients. Among them, the risk of liver cancer is three times higher than that of non-diabetic patients, and the risk of pancreatic cancer is eight times higher. Take pancreatic cancer as an example. The relationship between diabetes and pancreatic cancer has long been overlooked and many diabetic patients believe it is unfounded. Clinically, we found that diabetic patients have about 80% increased risk of pancreatic cancer compared to non-diabetic patients; more than half of pancreatic cancer patients also have diabetes; and up to 1% of new diabetic patients are diagnosed with pancreatic cancer within 3 years. It can be seen that diabetes is closely related to the occurrence and development of pancreatic cancer; it can be both an early manifestation of pancreatic cancer and a risk factor that promotes the occurrence and development of pancreatic cancer. Although the risk of pancreatic cancer decreases gradually with the duration of diabetes, long course diabetes is still an independent risk factor for pancreatic cancer. For middle-aged and elderly people with sudden onset of diabetes (especially those without family history of sugar), or diabetic patients with symptoms such as upper abdominal distension, low back pain, loss of appetite, yellow staining of skin or sclera, or sudden worsening of diabetic symptoms such as thirst and polyuria, or those with large fluctuation of blood sugar and uncontrollable hyperglycemia, or those who have always had good control of blood sugar and have unexplained hyperglycemia, be alert to the possibility of pancreatic cancer. How to prevent diabetes? Red onions are recommended for their anti-cancer, diabetes and heart disease prevention effects. Recent research at the University of Guelph in Canada has shown this, and because of the results of this study, scientists will even use red onions to make anti-cancer drugs in the future. 6, hepatitis The WHO Global Hepatitis Programme Director Hernschall pointed out that hepatitis is one of the major diseases facing the world. Based on 2015 data, the Global Hepatitis Report 2017 shows that about 325 million people worldwide are infected with chronic hepatitis B virus or hepatitis C virus, with 257 million of them infected with hepatitis B virus and 71 million with hepatitis C virus. If these hepatitis patients cannot be treated, they face long-term fatal diseases, including cirrhosis and liver cancer, Hernschall said. Although hepatitis does not necessarily develop into liver cancer, hepatitis is indeed one of the main causes of liver cancer. Therefore, hepatitis patients must be treated aggressively. Experts say that early antiviral treatment for chronic hepatitis is very important to prevent cirrhosis and liver cancer. If there are hepatitis patients in the family, it is even more important to do hepatitis prevention work, including prevention of mother-to-child transmission and blood transmission, as well as related vaccinations.
