Be alert to body signals and guard the health defense line

Being alert to body signals and guarding the health defense line, cancer, a serious threat to human health, often catches people by surprise because of its concealment and complexity. However, early detection of cancer is the key to improving treatment success and survival. This article will give you a detailed introduction to the early characteristics of cancer, help you alert to the body’s abnormal signals, take timely measures to protect the health line of defense. 1. Diversity of early characteristics of cancer The early characteristics of cancer vary according to its location and pathological type. Common early features include: Persistent fever: Cancer patients often have unexplained persistent fever, especially hematological tumors such as leukemia, lymphoma and so on. This fever usually does not exceed 38.5.d egree. C. and tends to occur at fixed times of the day. Weight loss and emaciation: Cancer is a wasting disease. The rapid growth of tumor cells consumes a lot of nutrients from the body, resulting in weight loss and emaciation. If the weight drops significantly in a short period of time (more than 5% -10%) and can not be explained by other reasons, we should be highly alert to the possibility of cancer. Pain and discomfort: In the early stages of cancer, tumor cells may invade surrounding tissues and organs, causing pain and discomfort. This pain may be manifested as local tenderness, dull pain or persistent pain, and gradually aggravated. Digestive abnormalities: digestive system cancer such as gastric cancer, intestinal cancer, etc., early may appear nausea, vomiting, indigestion, acid reflux, heartburn and other symptoms. Changes in stool characteristics and habits are also typical early symptoms of intestinal tumors. Respiratory and circulatory system symptoms: Respiratory system cancer such as lung cancer, early may appear cough, expectoration, bloody sputum, chest distress, shortness of breath and other symptoms. Tumors near the heart may compress the heart and blood vessels, causing palpitation and hypertension. Skin and mucous membrane changes: Some cancers may cause abnormal changes in the skin or mucous membrane, such as skin ulcers, bleeding, pigmentation or depigmentation. Oral leukoplakia may be a precancerous lesion of oral cancer. Lymph node enlargement: Lymph nodes are an important part of the immune system, and cancer patients often have symptoms of lymph node enlargement. Especially when the lymph nodes in the neck, armpit or groin are enlarged and do not disappear for a long time, the texture is hard, painless or tender, we should be alert to the possibility of tumors. 2. Strategies to improve the early detection rate of cancer Regular physical examination: Regular physical examination is an important means to detect early symptoms of cancer. Through blood examination, imaging examination and other means, abnormal changes in the body can be found in time. Self-examination: Learning to self-examine is also an effective way to improve the early detection rate of cancer. For example, women should have monthly breast self-examinations to detect early signs of breast cancer, while men should watch their urination for signs of prostate cancer. Pay attention to family history: Family history is an important reference factor for cancer risk. If you have cancer in your family, especially in your immediate family, you may be at increased risk of developing cancer. Therefore, we should pay more attention to our physical condition and carry out relevant examinations regularly. Maintain a healthy lifestyle: a healthy lifestyle is an important measure to prevent cancer. Including balanced diet, moderate exercise, smoking cessation and alcohol restriction, and maintaining psychological balance. These measures can help reduce the morbidity risk of cancer and improve the body’s immunity. 3. Conclusion Early detection and treatment of cancer is the key to improve survival rate. By understanding the early characteristics of cancer and being alert to abnormal signals in the body, we can detect problems earlier and take measures. At the same time, strategies such as regular physical examination, self-examination, attention to family history and maintaining a healthy lifestyle can also help to improve the early detection rate of cancer. Let’s work together to protect our health! Hopefully, this article will help you better understand the early characteristics of cancer and how to improve the early detection rate.
