The best way to treat cancer is to make early detection, but most of the early cancers have no obvious symptoms. Therefore, it is suggested that people over 40 should pay attention to the subtle changes in their daily life. If there are the following ten “precursors”, they should pay extra attention and go to the hospital for examination.

  1. Recurrent fever is a common symptom of infection, but fever of unknown cause may be a dangerous sign. When cancer spreads to other organs of the body, it usually leads to fever. Lymphoma, leukemia and other blood cancers also have fever symptoms. Necessary examinations include: X-ray chest X-ray, CT scan, MRI, etc.
  2. Weight loss if you don’t increase the amount of exercise or decrease the diet within a month, but your weight drops by 10% for no reason, you should see a doctor in time. Rapid weight loss, anorexia, recurrent diarrhea and constipation are the most common symptoms of lung cancer, gastric cancer, kidney cancer and colorectal cancer. For women, hyperthyroidism may also occur.
  3. Fatigue fatigue is a common manifestation of cancer development, but for leukemia, colorectal cancer and gastric cancer, fatigue may occur at the early stage of the disease. Fatigue can also be seen in normal people. Cancer fatigue is different from ordinary fatigue. Ordinary fatigue will disappear after a rest. However, cancer fatigue can hardly be improved no matter how much rest.
  4. Dysphagia long term dysphagia, poststernal pain, foreign body sensation in esophagus, dyspepsia, etc. if the cause of cerebrovascular disease is excluded, it may be a sign of laryngeal cancer, esophageal cancer and gastric cancer, X-ray chest X-ray or gastroscopy should be performed as soon as possible.
  5. Cough does not stop. If the unexplained cough continues, with or without blood, lasting for more than 3-4 weeks, especially those who have a history of smoking for many years, they should see a doctor in time, which may be a sign of lung cancer or laryngeal cancer.
  6. Lymph node changes no matter which part of the body, if the lymph node continues to grow, especially in the armpit or neck, for more than one month, it is likely to be a symptom of breast cancer, lung cancer or brain cancer.
  7. Local pain if pain occurs in a certain part of the body for more than a week, the cause should be found out as soon as possible, because pain without reason may be a sign of cancer. Long term abdominal pain is the symptom of liver cancer, gastric cancer, pancreatic cancer and colorectal cancer, chest pain is the symptom of esophageal cancer and lung cancer, and bone pain is the symptom of cancer metastasis.
  8. Women with breast lumps should be extra careful if they find breast skin redness and lumps. Nipple depression, and often out of liquid, is also a bad signal. For men, if the breast skin wrinkle, nipple contraction or asymmetry, nipple size and shape change, breast swelling, hard mass, etc., are manifestations of nipple inflammation, but also symptoms of breast cancer.
  9. Skin changes: sudden lumps or pigmentation on the skin, with obvious changes, may be a sign of skin cancer. You should see a doctor immediately after a few weeks of observation. In addition, once the skin suddenly bleeding or abnormal peeling, should also see a doctor.
  10. Abnormal bleeding includes hematochezia, hematuria and progressive anemia. In addition to hemorrhoids, hematochezia is likely to be a symptom of colorectal cancer. In addition to hematochezia, if the tumor grows near the anus, it may also have symptoms such as thinner stool, increased frequency, and even cause difficulty in defecation. Colonoscopy screening is recommended if necessary. If there is painless hematuria or dysuria, except for stones or inflammation, bladder cancer or renal cancer should be vigilant.
