Cancer is a word that many people fear. Early detection of cancer symptoms is the key to improving the chances of survival of cancer patients, so knowing cancer signals can save lives! Let’s take a look at these dangerous signals and avoid them as early as possible! Silent cancer signals 1. Unexplained wasting. Rapid weight loss in a short period of time is often the first signal of cancer. Sudden weight loss is most common in breast cancer and lung cancer patients, and others include liver cancer and intestinal cancer. If you do not exercise or lose weight, but inexplicably lose 10% of your body weight, you should seek medical attention promptly. 2.Frequent fever or infection. Infections in the body can lead to fever, and unexplained persistent fever may be a sign of cancerous conditions such as lymphoma. Leukemia may also lead to recurrent infections, fatigue, pain and other flu-like symptoms. 3. Weakness and fatigue. A variety of cancers may cause this symptom. If you feel weak and tired despite adequate sleep and rest, you should see a doctor. 4. Wheezing or shortness of breath. Severe and obvious shortness of breath, chest pain or coughing up blood may be symptoms of lung cancer. 5.Chronic cough and chest pain. Symptoms similar to cough or bronchitis may be symptoms of leukemia and lung cancer. Chest pain may also extend to the shoulder and arm. Cough and hoarseness for more than 6 weeks should be careful of laryngeal cancer, thyroid cancer, esophageal cancer or lung cancer. 6. Abdominal distension and pain. Unexplained abdominal distension should be borne in mind for ovarian cancer. Severe pelvic distention and pain may also be a common symptom of fibroids, ovarian cysts and other reproductive system diseases. In addition, inexplicable stomach pain or bloating after meals may be a sign of stomach cancer. 7.Chronic heartburn. Chronic heartburn (heartburn) should be investigated to see if it is caused by excessive stomach acid, and then the possibility of esophageal cancer and liver cancer should be investigated. 8.Intestinal problems. Patients with bowel cancer have more frequent bowel movements and have the feeling of not being able to solve them. The early symptom of pancreatic cancer is that the stool is white and smells strange. 9. Difficulty in swallowing. Mostly associated with esophageal cancer and laryngeal cancer, difficulty in swallowing is sometimes one of the early symptoms of lung cancer. 10.Jaundice. Sudden yellowing of skin or whites of eyes is mainly considered as liver or gallbladder disease, but it may also be a symptom of pancreatic cancer, cholangiocarcinoma and liver cancer. 11.Abnormal lumps. Abnormal masses in breast, testicles, groin, neck, abdomen, armpit or other areas should be promptly investigated by medical doctors for cancer risk. 12. New skin spots or mole changes. If new skin spots or moles change, or if skin sores remain untreated for a long time or crust over but bleed easily, you should be careful of skin cancer. 13.Change of nail. The appearance of brown or black streaks or spots under the nails should be considered as skin cancer. Suddenly larger finger ends and bent nails may be symptoms of lung cancer. Significantly white nails are sometimes a sign of liver cancer. 14.Pelvic or lower abdominal pain. Such pain with a heavy feeling in the pelvis may be a symptom of ovarian cancer. Infertile women, women with a family history of ovarian, breast or colon cancer, and women diagnosed with breast, colon, rectal or uterine cancer are at greater risk of developing ovarian cancer. 15. Long-term unexplained pain. If you have unexplained pain for more than 4 weeks, you should be concerned about bone cancer or testicular cancer. 16.Abnormal bleeding. Blood in urine may be a symptom of urinary tract infection, bladder cancer or kidney cancer. Blood in stool may be both hemorrhoid and bowel cancer symptom. Abnormal vaginal bleeding between menstrual cycles of women may be endometrial cancer symptoms. Vomiting blood and coughing up blood should be beware of stomach cancer, esophageal cancer or lung cancer. Excessive bruising or excessive bleeding may be a symptom of leukemia.
