Cancer is found late in our country, but we may be able to prevent it before it happens if we have knowledge about it and detect it early. Today, we will introduce some signs of cancer. Blood in the stool and occult blood Blood in the stool is a major manifestation of a cancer of the digestive tract. It may not be noticed at first, but if we find blood in stool every time we have a bowel movement, we must be alert! Cancer cells destroy the mucous membrane of the intestine and erode the blood vessels of the intestinal wall, which can cause blood in the stool. Of course it is most commonly identified with hemorrhoids, and I have that section in my blog. Nipple overflow and breast masses Unusual overflow from a woman’s nipples during non-lactating periods should be a cause for alarm. Especially bloody overflow. There are also breast masses. Breast masses should be detected and examined at a hospital. Increase in stool frequency or change in bowel habits According to our statistics, increase in bowel habits is the most common symptom of rectal cancer in elderly people. It should be taken seriously. Unexplained weight loss Nowadays, people are popular to lose weight, but if there is unexplained weight loss, it may not be good. It should be checked in hospital. Otherwise, the effect of weight loss may be mistaken for weight loss and can delay the condition. Unexplained coughing up blood Coughing is a common symptom for us. For example, a cold. Everyone has experienced coughing. However, if it is just a common cold and you cough up blood, and it is fresh blood, or blood in the sputum, do not ignore it and you should go to the hospital for examination. Weakness and anemia It is common to experience weakness and suboptimal health as our life is getting faster and faster, but if we experience significant weakness with a pale complexion, we should pay attention to it. A pale complexion is not always the result of “whitening”, but may be the result of anemia, which may be caused by chronic blood loss due to cancer.
