The 10 symptoms mentioned below are possible manifestations of cancer. Of course, these symptoms are not the official diagnostic criteria of cancer, and it cannot be said that having these symptoms is equal to having cancer, so don’t panic blindly. This article just wants to remind you to pay attention to your health, don’t ignore physical abnormalities, and go to the hospital for examination in time to clarify the cause if you have discomfort. 1. Hard nodes or lumps Certain cancers will have lumps in the corresponding areas. If you feel a “hard lump” in your neck, underarm, breast or other parts of your body, with a fixed position, hard texture and unclear edges when you touch it, and it does not fade away, you should pay attention to it. 2. Mole changes or white spots appear Benign moles generally have uniform color and 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 performance of melanoma. White spots in the mouth should also be taken seriously. Especially for long-term smokers, 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 promptly to clarify the cause. It is also important to be alert when ulcers and erosions with fixed locations in the mouth do not heal for a long time, and even bleeding, swollen lymph nodes in the neck, and affect pronunciation. 3, indigestion, persistent ulcer Gastrointestinal tract problems such as acute and chronic inflammation, ulcers, bleeding, polyps, stones, tumors, etc., may appear symptoms of indigestion. Gastric ulcers are usually painful 1 to 2 hours after meals, and then gradually reduce with great regularity. However, gastric ulcers should also be treated properly, and once there is persistent stomach pain, you should be alert to cancer. Persistent indigestion and ulcers, it is best to check earlier and review regularly to rule out the possibility of malignant tumors of the digestive tract in time. 4.Difficulty in swallowing food A common early symptom of esophageal cancer, besides feeling difficulty in swallowing food and the feeling of rubbing the esophagus, the lower middle part of the chest may also feel burning pain. As the disease progresses, this feeling will become more and more severe, and in the advanced stage, hoarseness, cough and difficulty in breathing will also appear. 5. Hoarseness, dry cough, blood in sputum These are common symptoms of lung cancer, especially for people over 40 years old who are used to smoking for a long time, the risk of lung cancer increases exponentially! Many patients with lung cancer are found to have dry cough and blood in sputum. 6. Tinnitus, abnormal hearing, nasal congestion Nasopharyngeal cancer often involves the nerves in the head and face, bringing about the above symptoms. If there is also blood in the sputum or a lump in the neck is felt, it is more important to be alert. In Guangdong, Guangxi, Jiangxi and Hunan, where the incidence is high, especially if there are family members who have had nasopharyngeal cancer in the family, it is especially important to pay attention to these symptoms. 7. Change in urine and stool traits Early bladder cancer and prostate cancer may manifest as sudden increase or decrease in urination or painless hematuria, while colon cancer changes may manifest as blood in stool or frequent diarrhea. All these symptoms remind you that it is time for timely examination. 8.Irregular menstruation The “irregular menstruation” here is mainly heavy bleeding, or irregular vaginal bleeding outside of menstruation or after menopause. When these symptoms occur, attention should be paid to clarify whether it is fibroids or cervical cancer. In addition, in early stage of cervical cancer, there are usually symptoms such as increased vaginal discharge, back pain, difficulty in urination, edema in legs and feet. In conclusion, we need to pay more attention to the abnormal body manifestations in normal days. 9.Prolonged fatigue or pain Normally, a good rest is enough to relieve fatigue soon. However, extreme fatigue needs to be taken seriously. Long-term fatigue and weakness caused by certain cancers will not improve much even after sufficient rest. There are various causes of body pain, but the pain caused by cancer is characterized by persistent pain that cannot be effectively relieved even by some basic pain medications. Pain, which is a signal sent by the body when abnormalities exist, should be taken seriously. 10. Weight loss or hypothermia If there is no change in eating habits and life rhythm, and no deliberate in dieting or weight loss, weight usually does not fluctuate drastically in a short period of time. American Cancer Society information 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 mainly manifests as regular afternoon and evening fever that resolves in the early hours of the next day. Among them, lymphoma is the most typical manifestation. If there is sudden weight loss or persistent fever, don’t hesitate to go to the hospital to clarify the cause. Can “superfoods” prevent cancer? Blueberries, beet, broccoli, garlic, green tea …… There are countless foods that people have high hopes of preventing cancer. But in reality, there is no such thing as a superfood. It’s just that some foods are indeed healthier than others, and eating more fruits and vegetables and enriching the variety of vegetables consumed on a daily basis can be of great benefit. However, the occurrence of cancer is a complex process, and it is not scientifically sound to expect that eating certain vegetables can prevent cancer 100% of the time. Only by adhering to a healthy lifestyle, such as not smoking, exercising more, maintaining a healthy weight and not drinking alcohol, can we reduce the incidence of cancer. Do “acidic foods” cause cancer? There are some rumors about cancer that are surprisingly persistent, although they do not even understand the basic biology, and “acidic food causes cancer” is one of them. It is believed that some “acidic foods” cause the blood to become acidic, which in turn increases the risk of cancer. However, there is a perfect buffer system in the human body to keep the pH of various body fluids within a small normal range, and it is impossible to change the pH of body fluids by eating a few more pieces of meat or a few oranges. And it is also nonsense to say that “acidic body causes cancer”. Cancer cells love sweet food? It is said that sugar will “nourish” cancer cells, so cancer patients should eliminate sugar. Sugar, also known as carbohydrates, is hydrolyzed into glucose and fructose in the body’s digestive system and then absorbed into the bloodstream, where it enters cells as a raw material for respiration to provide us with energy. All cells in our body, cancerous or not, need glucose to provide energy. Because cancer cells tend to grow more rapidly compared to normal cells, cancer cells have a greater need for glucose. There is also evidence that cancer cells break down glucose production capacity in a different metabolic pathway than normal cells. However, this does not mean that, unlike other carbohydrates in food, the sugar in sweets is not “available” exclusively to cancer cells. Our bodies do not decide which nutrients should be available to which specific cells.
