The following 10 symptoms are possible manifestations of cancer. Of course, these symptoms are not the official diagnostic standard of cancer, we can’t say that having these symptoms is equal to having cancer, don’t panic blindly. In this article, we just want to remind you to pay attention to your health, don’t ignore the abnormalities in your body, and go to the hospital for examination in time to clarify the causes. 1.Hard knots or lumps Certain cancers, is going to appear lumps in the corresponding parts. If you feel “hard lumps” in your neck, armpits, breasts or other parts of your body, with fixed location, hard texture, unclear edges when you touch them, and they will not subside, you should pay attention to them. Changes in moles or white spots Benign moles are generally uniform in color and have clear edges. If the warts or moles on the body, suddenly deepen in color, increase in size, itching, ulceration and bleeding, this may be the early manifestation of melanoma. White spots in the mouth should also be taken seriously. Especially for long-term smokers, if there are white spots in the mouth or on the dental bed that cannot be erased and persist for a long time, it is recommended to go to the hospital in time to clarify the cause. Ulcers and erosions in the mouth with a fixed location do not heal for a long time, and even bleeding, swollen lymph nodes in the neck, affecting pronunciation, should also be vigilant. 3, indigestion, persistent ulcers Gastrointestinal tract problems such as acute and chronic inflammation, ulcers, bleeding, polyps, stones, tumors and other problems, may appear indigestion symptoms. Gastric ulcers are usually painful for 1 to 2 hours after a meal, and then gradually reduce, very regularly. However, stomach ulcers also need to be treated properly, and once persistent stomach pain occurs, it is important to be on the lookout for cancer. For persistent dyspepsia and ulcers, it is better to have an early examination and regular review to exclude the possibility of malignant tumor of digestive tract in time. Difficulty in swallowing food A common early symptom of esophageal cancer is burning pain in the middle and lower part of the chest, in addition to difficulty in swallowing food and the feeling of rubbing the esophagus. As the disease progresses, this feeling will become more and more serious, and in the late stage, hoarseness, cough and difficulty in breathing will also occur. Hoarseness, dry cough, blood in sputum This is a common symptom of lung cancer, especially for those who are above 40 years old and used to smoking for a long period of time, the risk of lung cancer increases exponentially! Many lung cancer patients are found to have dry cough and blood in sputum. Tinnitus, abnormal hearing, nasal congestion Nasopharyngeal cancer often involves the nerves in the head and face, bringing the above symptoms. If there is also blood in sputum or lumps on the neck are touched, you should be more alert. In Guangdong, Guangxi, Jiangxi and Hunan where the incidence of nasopharyngeal cancer is high, especially if there are family members with nasopharyngeal cancer at home, you should pay attention to these symptoms. Early bladder cancer and prostate cancer may show sudden increase or decrease in urination, or painless hematuria, while colon cancer may show blood in stool or frequent diarrhea. All these symptoms remind you that it is time for timely examination. Irregular menstruation The “irregular menstruation” here is mainly heavy bleeding, or irregular vaginal bleeding outside the menstrual period or after menopause. With these symptoms, you should pay attention to clarify whether it is uterine fibroids or cervical cancer. In addition, in the early stage of cervical cancer, there are usually symptoms such as increased vaginal discharge, back pain, difficulty in urination, edema of legs and feet. All in all, it is necessary for people to pay more attention to the abnormal manifestations of the body on weekdays. 9, long-term fatigue or pain In general, as long as you take a good rest, you will soon be able to relieve the fatigue. However, extreme tiredness needs to be taken seriously. Long-term fatigue and tiredness caused by certain cancers will not improve much even after sufficient rest. Body pain can be caused by a variety of reasons, but pain caused by cancer is characterized by persistent pain that is not effectively relieved by even some basic pain medications. Pain, a signal from the body when abnormalities exist, should be taken seriously. 10, weight loss or hypothermia If the eating habits, rhythm of life have not changed, and not deliberately in the diet, weight loss, weight is generally not in a short period of time drastic fluctuations. Information from the American Cancer Society shows that esophageal cancer, lung cancer, pancreatic cancer, stomach cancer and many other cancers may lead to sudden weight loss. Cancer patients sometimes experience ‘tumor fever’, which is mainly characterized by regular afternoon and evening fevers that resolve in the early morning hours of the following day. Of these, lymphoma presents most typically. If there is sudden weight loss or persistent fever, don’t hesitate to go to the hospital to find out the cause. Can “superfoods” prevent cancer? Blueberries, beet, broccoli, garlic, green tea …… There are countless types of food that have been pinned with high hopes of preventing cancer. But in reality, there are no superfoods. It’s just that some foods are indeed healthier than others, and eating more fruits and vegetables and enriching the variety of vegetables you consume on a daily basis can be of great benefit. However, the occurrence of cancer is a complex process, and there is no scientific basis for expecting that eating a specific type of vegetable can prevent cancer 100%. Only long-term adherence to a healthy lifestyle, such as not smoking, exercise, maintain a healthy weight and do not drink alcohol, can reduce the incidence of cancer. Do “acidic foods” cause cancer? There are some rumors about cancer that are surprisingly persistent even though they don’t even have basic biological knowledge, and “acidic foods cause cancer” is one of them. The idea is that some “acidic foods” cause the blood to become acidic, which in turn increases the risk of cancer. However, the human body has a perfect buffer system, so that the pH of various body fluids to maintain a small range of normal values, eat a few pieces of meat or a few oranges, it is impossible to change the pH of body fluids. And “acidic body cancer” is also nonsense. Cancer cells love sweets? Some people say that sugar “nourishes” cancer cells, so cancer patients should avoid sugar. Sugars, also known as carbohydrates, are hydrolyzed into glucose and fructose in the human digestive system, then absorbed into the bloodstream, and then into the cells as a raw material for respiration to provide us with energy. All cells in our body, whether cancerous or not, need glucose for energy. Since cancer cells tend to grow more rapidly compared to normal cells, cancer cells have a greater need for glucose. There is also evidence that the metabolic pathways by which cancer cells break down glucose for energy production are different from those of normal cells. However, this does not mean that, unlike carbohydrates in other foods, the sugar in sweets is not “available” exclusively to cancer cells. Our bodies don’t decide which cells should get which nutrients.
