In China, cancer is often found at an advanced stage and the chance of eradication is lost. However, early detection is entirely possible, and the key is to be alert and familiar with the early manifestations of common cancers. At the beginning, cancer is in a small localized state, which is called “carcinoma in situ” in medical science. For example, cervical cancer generally takes 5-8 years; skin cancer takes about 10 years; esophageal cancer generally takes 10 months to 6 years to transform from esophageal cell hyperplasia to squamous epithelial cell carcinoma. The time required for lung cancer to double in size is about 4 to 12 months. Therefore, in such a long period of time, early detection is entirely possible if both patients and medical personnel are vigilant. Moreover, most of the cancers in human body grow on the surface or can be detected by simple instruments. Even for some cancers that grow deep in the body, modern medicine has many methods to detect them at an early stage. In short, most cancers can be detected at an early stage if one is familiar with the early manifestations of common cancers. So, what are the early symptoms of common cancers? Generally speaking, the following warning signs should be noted: 1.Unexplained weight loss, weakness, irregular pain in upper abdomen, loss of appetite, especially aversion to meat. 2, non-pregnant and breastfeeding women, have nipple water or can squeeze out fluid. 3.A gradually increasing lump in any part of the body such as breast, neck or abdomen. 4.Dry cough, blood in the sputum, chest pain and chest tightness that cannot be cured for a long time. 5.Women above middle age have small amount of vaginal bleeding after sexual intercourse, or irregular vaginal bleeding in general, or menstruation after several years of menopause, and leucorrhea increases significantly. 6.Progressive jaundice and epigastric mass without abdominal pain. 7. Rapid enlargement of the liver, accompanied by pain in the liver area. 8.Unexplained painless hematuria. 9.Skin ulcers that do not heal for a long time. 10.A sudden enlargement of the mole, accompanied by burning, itching, breaking, painful bleeding or loss of hair on the mole. 11.Recurrent fever and persistent dental bleeding, subcutaneous bleeding and progressive anemia. 12.Recurrent unexplained high fever. 13.White spots on the mucous membrane of the mouth, or on the vulva of women or the glans of the penis of men, and rapidly expanding and itching discomfort. 14.Progressive weakness of both lower limbs, abnormal sensation, movement disorders or incontinence of urine and stool sometimes. 15.Fracture of large bones such as femur and humerus without obvious external force. 16.Sensation of foreign body obstruction, tingling sensation behind the sternum when eating and swallowing or slow passage of food. 17.Nasal congestion, frequent small amount of nasal bleeding or blood in the nasal discharge, accompanied by migraine, dizziness, tinnitus and swollen lymph nodes felt in the upper part of the neck under the earlobe in front and behind. 18.Changes in bowel habits, or frequent alternation of diarrhea and constipation, or stools with pus and blood, or thin and flattened stools. 19.Progressively increasing headache with sudden and transient visual disturbance and vomiting. 20.Adolescents with severe pain and swelling in the elbow or knee joints, which are not treated with anti-rheumatic drugs or antimicrobial drugs. The above are 20 representative symptoms of suspected malignant tumor. If you find these symptoms, you should pay enough attention to them and go to the hospital for diagnosis as soon as possible. However, it does not mean that any symptom mentioned above is cancer. The final diagnosis should be made by doctors after detailed examination by various methods. Otherwise, it will bring unnecessary burden to yourself and your family. Early symptoms of several kinds of common cancers Esophageal cancer: delayed swallowing of food, stagnation or slight choking sensation, which may subside on its own, but may appear again after a few days, recurring and gradually worsening. Or when swallowing or eating, it always feels pain in the sternum. Usually, it feels like a foreign body in the esophagus and is not related to eating, but persists, and drinking water or swallowing food cannot make it disappear. Gastric cancer suddenly appears unexplained indigestion symptoms, and it is more persistent and fast progressing; the prominent manifestations are rapid decrease of appetite, abdominal fullness and discomfort after eating, and at the same time, the weight is significantly reduced. In addition, people who did not have stomach pains (“heartburn”) in the past suddenly have recurrent stomach pains; although they had stomach pains in the past, the intensity, nature and duration of the pains have suddenly changed recently, and the drugs that were effective in treatment have become ineffective or poor. Colorectal cancer: Anyone over 30 years old who has abdominal discomfort, vague pain, bloating, change in stool habit, constipation, diarrhea or alternately, feeling of falling, blood in stool, followed by anemia, fatigue and weakness, and lump in the abdomen should consider the possibility of colorectal cancer. The first warning sign of colon cancer is a limited, intermittent, hidden pain along the colon. The obvious feeling of falling with blood in stool is a signal of rectal cancer (colon cancer includes colon cancer and rectal cancer). Liver cancer Early stage liver cancer has no specific symptoms, and if there are some complex manifestations of pre-cancerous diseases. However, patients with chronic hepatitis or cirrhosis should be highly alerted if they have stabbing pain or increased pain in the right upper abdomen or liver area, physical discomfort, loss of appetite, progressive indigestion, accompanied by persistent diarrhea and significant weight loss. Nasopharyngeal cancer One common feature of the early signs of nasopharyngeal cancer is that the symptoms (and signs) mostly occur unilaterally. Unilateral snot and blood (meaning blowing out), unilateral nosebleed, unilateral tinnitus, unilateral hearing loss, unilateral headache, and unilateral cervical lymph node enlargement. Brain tumors The main manifestations are headache and vomiting. The headache is very special, often the heaviest when waking up in the early morning, and can gradually reduce after waking up, obvious in the forehead, posterior occipital area and both sides. The headache is often accompanied by vomiting, which is not related to eating, especially when the pain is severe, and the headache will be relieved after vomiting. Lung cancer Cough is an early symptom of lung cancer, characterized by paroxysmal irritating choking cough, with the feeling of coughing without purging. If there is no improvement after 2 weeks of anti-inflammatory treatment, the possibility of lung cancer should be alerted. If there is no improvement after 2 weeks of anti-inflammatory treatment, you should be alerted to the possibility of lung cancer. Another warning sign of lung cancer is intermittent recurrent small amounts of bloody sputum, or sputum with blood in it. In addition, symptoms such as chest and back pain, chest tightness and fever may also occur. Breast cancer Abnormal changes in the breast, such as thickening or lumpiness, swelling, slight concavity (“dimple sign”), thickening and redness of the skin, nipple deformation, retraction or scaling, pain or pressure, and sudden unilateral nipple flow (milk-like, blood-like, water-like fluid) in non-lactating women. Cervical cancer The early symptoms of cervical cancer are mainly as follows. Vaginal spotting bleeding after sexual intercourse, defecation or activity, blood mixed with vaginal discharge. It appears in small amounts at first and often stops on its own. Irregular vaginal bleeding, especially sudden vaginal bleeding after many years of menopause. Increased leukorrhea, bloody or flesh-washing. Pain in the lower abdomen and lower back. Any one of the above should be checked promptly. The focus is on irregular vaginal bleeding, contact bleeding and excessive leukorrhea. Leukemia Fever, bleeding and anemia are the three major early symptoms of (acute) leukemia. A fever of 37.5°C-38.5°C often indicates an infection, such as inflammation of the skin, respiratory tract, intestines, oral cavity, urinary system, etc. Bleeding can occur at any site, but is common in the subcutaneous, oral, nasal, and gingival areas. The degree of bleeding can range from petechiae and petechiae to hemorrhage from the mouth and nasal cavity. Anemia is due to impaired hematopoiesis and bleeding in the red system and evolves rapidly, and the patient is pale. In addition, swollen lymph nodes and bone and joint pains may occur, and light pressure pain in the sternum is characteristic. 15 early symptoms of cancer 1. Abdominal distension Many women think that abdominal distension is extremely common and there is no need to make a fuss about it. However, this may be a symptom of ovarian cancer. According to Liu Juntian, director of Cancer Preventive Medicine Center of Tianjin Cancer Hospital, persistent abdominal swelling, pressure and pain, gastrointestinal discomfort, difficulty in eating or feeling full easily for several weeks may be signs of ovarian cancer. 2. Irregular bleeding According to Dr. Dailey, an American oncologist, abnormal vaginal bleeding and urinary and fecal bleeding between menstrual cycles are easily ignored by women. They are likely to be a major sign of endometrial cancer, a common gynecological cancer, and at least 3/4 of women who have this sign are tested for endometrial cancer. Bleeding in the stool, on the other hand, may be a sign of colon cancer. 3.Breast lumps Women should be extra cautious if they find red skin and lumps on their breasts. “Especially if you have a rash on your breasts that doesn’t go away for weeks, you must get it checked out.” Oncologist Hannah K. says Dr. Linden. In addition, she notes, non-lactating women with sunken nipples and often fluid flow are also bad signs. 4. Pain The American Cancer Society says that body pain increases with age. But when pain inexplicably appears in a part of the body and lasts for more than a week, the cause should be identified as soon as possible because unexplained pain may be a sign of cancer. For example, chronic abdominal pain is a symptom of colorectal cancer, chest pain may be caused by lung cancer, and bone ache may be a symptom of cancer metastasis. Liu Juntian pointed out that pancreatic cancer will manifest in the epigastric region, such as persistent dull pain or colic around the umbilicus or right upper abdomen, which can be paroxysmal or persistent, usually gradually worsening and radiating to the lower back. 5. Lymph node changes Dr. Linden said that no matter which part of the body, especially in the armpit or neck, swollen lymph nodes should not be taken lightly. If the lymph nodes continue to increase in size for more than one month, it is likely to be a symptom of breast cancer or brain cancer. 6. Fever Fever is usually caused by flu, pneumonia or other inflammatory diseases, however, unexplained fever may be a dangerous sign. The American Cancer Society says that fever usually results when cancer spreads to other organs in the body. Blood cancers such as lymphoma and leukemia also have fever symptoms. Xu Zhijian, director of the Cancer Prevention Department at the Cancer Hospital of the Chinese Academy of Medical Sciences, added that lymphoma can manifest itself as a persistent low-grade fever of around 38 degrees Celsius in the early and middle stages, or a high fever when combined with infection. Necessary examinations include: X-ray chest X-ray, CT scan, MRI, etc. 7, weight loss It is indeed gratifying to lose weight without much effort, but if within a month neither increased exercise nor reduced diet, but somehow weight loss of 10%, then you should promptly seek medical attention. Rapid weight loss, anorexia, recurrent diarrhea and constipation are the most common symptoms of lung, stomach, kidney and colorectal cancers, and for women, it may also be hyperthyroidism. 8, persistent abdominal pain dressed as depression American Cancer Society official Leonardo? Dr. Leonardo Lichtenfeld, an official of the American Cancer Society, said that if you have persistent abdominal pain with depressive symptoms, you are likely to have pancreatic cancer. This is because experts have found that depression has a great relationship with pancreatic cancer. Other symptoms include: jaundice or abnormal gray color of stool. 9. Fatigue Generally speaking, feeling fatigue is a sign that cancer has developed, but for leukemia, intestinal cancer and stomach cancer, fatigue may be felt at the early stage of development. What is the difference between fatigue of cancer and ordinary fatigue? According to the American Cancer Society experts, ordinary fatigue will disappear with rest, while cancer fatigue will feel difficult to improve no matter how to rest. 10.Coughing and shivering Lanette, Georgetown University School of Medicine, USA Dr. Micheli said that if inexplicable coughing persists for more than 3-4 weeks, you should see a doctor promptly, it may be a sign of lung or throat cancer. 11. Difficulty in swallowing Long-term difficulty in swallowing may be a sign of laryngeal cancer, esophageal cancer and stomach cancer, and should receive X-ray chest X-ray or gastroscopy as soon as possible, according to Dr. Lee Chilton Field. The so-called dysphagia, according to Liu Juntian, generally refers to pain behind the sternum and foreign body sensation in the esophagus when eating. Some people may feel like there are vegetable leaves, debris or rice-like objects attached to the esophageal wall even if they do not eat, and they may feel that the food goes down slowly or even stays in the esophagus after swallowing it. 12, skin changes U.S. Fox Chase Cancer Research Center in Philadelphia, oncologist Mary? Dr. Daly warns that sudden appearance of skin lumps or hyperpigmentation and significant changes may be signs of skin cancer. After a few weeks of observation, you should seek immediate medical attention. In addition, no matter how old or young you are, you should also see a doctor if your skin suddenly bleeds or flakes abnormally. 13, abnormal bleeding Dr. Micheli said that blood in the stool, in addition to hemorrhoids, is likely a symptom of bowel cancer and should be screened for colonoscopic bowel cancer if necessary. Chen Shan, chief physician of urology department of Beijing Tongren Hospital, also reminded that middle-aged and elderly people over 40 years old should be alerted to bladder cancer or kidney cancer if they have painless blood in urine or difficulty in urination, except for female periods. In addition to blood in stool, bowel cancer may also show symptoms such as thinning of stool and increase in frequency, or even cause difficulty in stool if the tumor grows near the anus. 14, oral changes The American Cancer Society points out that smokers should pay special attention to the white patches on the mouth and tongue, which may be a precursor of oral cancer: mucosal leukoplakia. 15.Indigestion Women (except during pregnancy) with prolonged and unexplained continuous indigestion may be a symptom of esophageal cancer, laryngeal cancer and stomach cancer.
