The human body may suffer from many types of cancer, such as cancer of the digestive system, skeletal system, blood system, respiratory system, etc. Different types of cancer show different symptoms, which may not be limited to five signs. And the manifestation of cancer in early, middle and late stages may also be different. Early stage cancer may have no clinical symptoms or the appearance of symptoms is not obvious, so it is difficult to be detected according to the physical manifestations. In contrast, middle and late stage cancer will generally cause systemic symptoms, such as pain, wasting, bleeding, loss of appetite, abnormal digestion, abnormal stool and urine, abnormal body temperature, etc. 1. Pain: Generally, early stage cancer will not show pain or hidden pain which is easy to be ignored, but when it develops to middle and late stage, it will show obvious pain or severe pain, such as liver cancer; 2. Wasting: With the invasion of normal tissues by cancer cells, the cancer tumor will abnormally grow and consume a lot of nutrients in the body, and patients with terminal cancer will be as thin as a bone. Some cancers of the esophagus and digestive tract will prevent patients from eating normally, resulting in nutrient deficiency and manifesting as body wasting, such as esophageal cancer and stomach cancer. In addition, due to the inability of nutrition to supply normal demand, fatigue and weakness may also occur frequently; 3. Bleeding: Damage to tissues by advanced cancer cells will cause bleeding, such as bleeding of digestive tract mucosa caused by advanced gastric cancer and bleeding of respiratory tract mucosa easily caused by lung cancer. Liver cancer, prostate cancer, colon cancer, etc., will rupture and bleed as the cancer grows, which may cause anemia if not corrected or rehydrated in time; 4. Loss of appetite: the body is attacked by cancer cells, which will cause loss of appetite. Advanced cancer patients may not be able to eat at all and have to rely on intravenous input of nutrient solution to maintain their strength; 6. Digestive abnormalities: without obvious causative effect, nausea, vomiting, This may be caused by cancer in the digestive system, such as liver cancer, pancreatic cancer, etc.; 7. Abnormal stool and urine: For example, colon cancer and rectal cancer, abnormal stool, such as pus and blood stool, mucus stool or blood in stool, or even alternating diarrhea and constipation, may occur. As in the case of bladder cancer, there may be hematuria visible to the naked eye, etc.; 8. Abnormal body temperature: cancer patients have low body quality and are easily invaded by pathogens, which may cause fever, and may have repeated fever or high fever that does not subside. Patients with leukemia or lymphoma may even have unexplained hypothermia or hyperthermia; 9. Other: For example, breast cancer, unexplained lumps may be touched in the breast area, usually without pressure pain. In addition, if the existing moles on the body suddenly increase in size, even with itching and bleeding, you need to beware of the occurrence of melanoma.
