Many women think that abdominal bloating is extremely common and no need to make a fuss about it. However, it may be a symptom of ovarian cancer. According to Liu Juntian, director of 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 American oncologist Dr. Daley said that abnormal vaginal bleeding between menstrual cycles and bleeding from urine and feces are easily ignored by women. They are likely to be a big sign of endometrial cancer, a common gynecological cancer, and at least 3/4 of women are examined for endometrial cancer after having this sign. Bleeding in the stool may be a sign of colon cancer. 3. Hard Breast Lumps Women should be extra cautious if they notice redness and lumps in the skin of their breasts. “Especially if a rash develops on the breast and doesn’t go away for weeks, it’s important to get it checked out.” Says oncologist Dr. Hannah Linden. Additionally, she notes that non-breastfeeding women with dimpled nipples that often ooze fluid are also a bad sign. 4, Pain The American Cancer Society says that body pain increases with age. But a part of the body inexplicable pain and lasted more than a week, should be identified as soon as possible, because unexplained pain may be a sign of cancer. For example, long-term abdominal pain is a symptom of colorectal cancer, chest pain may be caused by lung cancer, and bone pain 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, and usually worsens gradually and radiates to the lower back. 5, lymph node changes Dr. Linden said, no matter what part of the body, especially the armpit or neck lymph node enlargement, do not take it lightly. If the lymph nodes continue to enlarge for more than 1 month, it is likely to be a symptom of breast cancer or brain cancer. Fever Fever is usually caused by flu, pneumonia or other inflammation, however, unexplained fever may be a sign of danger. According to the American Cancer Society, when cancer spreads to other organs of the body, it usually leads to fever. 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 present as a persistent low-grade fever of around 38 degrees Celsius in the early to mid stages, or a high fever when combined with an infection. Necessary examinations include: X-ray chest X-ray, CT scan, MRI examination, etc. 7, inexplicable weight loss No effort to lose weight is indeed gratifying, but if neither increased exercise in a month, and did not reduce the diet, the weight is inexplicably decreased by 10%, it should be timely to seek medical attention. Sharp weight loss, anorexia, repeated diarrhea and constipation are the most common symptoms of lung cancer, stomach cancer, kidney cancer and colorectal cancer, which may also be hyperthyroidism for women. 8, persistent abdominal pain with depression Dr. Leonardo Lichtenfeld, an official of the American Cancer Society, said that if you have persistent abdominal pain with symptoms of depression, you are very likely to have pancreatic cancer. This is because experts have found that depression is highly associated with pancreatic cancer. Other symptoms include: jaundice or abnormal gray stools. 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 the disease. What is the difference between cancer fatigue and common fatigue? American Cancer Society experts said that ordinary fatigue will disappear after a break, while cancer fatigue no matter how to rest, will find it difficult to improve. 10, cough more than the United States Georgetown University School of Medicine Ranit? Dr. Micheli said, if the inexplicable cough persists for more than 3-4 weeks, you should see a doctor in time, it may be a sign of lung or throat cancer. 11, dysphagia Dr. Lichtenfeld said that long-term dysphagia, may be a sign of laryngeal cancer, esophageal cancer and stomach cancer, should receive X-ray chest X-ray or gastroscopy as soon as possible. The so-called dysphagia, Liu Juntian introduced, generally refers to the pain behind the sternum when eating, foreign body sensation in the esophagus, some people, even if they do not eat, but also feel the esophageal wall like there are leaves, debris, or rice-like objects attached, after swallowing the food will feel the food downstream is slow, and even stay in the esophagus. 12. Skin changes: Oncologist Dr. Mary Daley of Fox Chase Cancer Research Center in Philadelphia reminds that the sudden appearance of skin lumps or hyperpigmentation, and the changes are obvious, may be a sign of skin cancer. Medical attention should be sought immediately after a few weeks of observation. In addition, no matter how old or young, once the skin suddenly bleeding or abnormal peeling, should also see a doctor. 13, abnormal bleeding Dr. Micheli said, blood in the stool, in addition to hemorrhoids, is likely to be a symptom of bowel cancer, if necessary, should receive colonoscopy bowel cancer screening. Chen Shan, chief physician of urology department of Peking Tongren Hospital, also reminded that middle-aged and old 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, in addition to women’s menstruation. In addition to blood in stool, if the tumor grows close to the anus, bowel cancer may also show symptoms such as thinning of stools and increased frequency, or even cause difficulty in bowel movement. 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 the precursor of oral cancer: mucosal leukoplakia. Dyspepsia Women (except during pregnancy) with prolonged and unexplained persistent dyspepsia may be the symptom of esophageal cancer, laryngeal cancer and stomach cancer.
