There are more signs of having tumor on the body, because tumors in different parts of the body produce different symptoms. However, most of them will show some atypical symptoms, such as bleeding, lump, ulcer, difficulty in swallowing, mole wart change, cough and sputum, etc. When unexplained above symptoms occur, it does not necessarily mean that tumor has occurred, but it should be taken seriously and relevant examinations should be completed in time to clarify the specific situation. 1. Bleeding: Bleeding can be in different forms such as hematuria, coughing blood, blood in stool, nosebleed, irregular vaginal bleeding, etc., and appear in different parts of the body, such as urinary tumor and respiratory tumor. 2. Lumps: Some tumors can cause abnormal lumps in the body. Most of them have pressure pain and grow gradually, such as in the neck, abdomen, breast, body surface, etc. They can be seen in malignant lymphoma, thyroid cancer, breast cancer, etc.; 3. Ulcers: unexplained ulcers can appear on the body, and they appear repeatedly and persist for a long time; 4. Difficulty in swallowing: patients can have symptoms of difficulty in swallowing, which tend to worsen progressively, and they need to be alert to the presence of esophageal cancer. 5.mole and wart changes: unexplained moles or warts may appear on the body and increase in size significantly, so consider the risk of cancer, such as malignant melanoma; 6.cough and sputum: when coughing, coughing, wheezing, coughing with blood and other respiratory symptoms appear, also consider the risk of cancer, such as lung cancer; 7.other symptoms: when unexplained hoarseness, pain, stool changes, and unexplained When symptoms such as facial pallor, body weakness and weight loss occur, they may also suggest the existence of tumor. Therefore, the signs of tumor are not specific. Advanced tumors may also be accompanied by generalized fever, poor appetite, emaciation, anemia and other symptoms.

If malignant tumor is diagnosed, appropriate treatment should be actively adopted according to different stages and tumor sites and other factors. Early benign tumors have a better chance of treatment after resection, while patients in middle and late stages should cooperate with doctors to control disease development, improve quality of life and prolong survival.
