Most cancers have reached the middle and late stages when they are diagnosed. They miss the best time to undergo surgery or chemoradiation and 5-year survival rate has decreased. It does not mean that there is no trace of cancer in the early stages, but the symptoms are not significant and difficult to be discovered or directly ignored, or misdiagnosed, which increases the difficulty of treatment and even loses precious lives in just a few months. If you always have the following symptoms, you need to think of cancer as soon as possible.
What are the early symptoms of cancer?
1, blood
stool is commonly found in hemorrhoids, gastric ulcer or duodenal ulcer , intestinal polyps and dysentery , etc. But it is also possible to be intestinal cancer, which is characterized by a dark red blood, a mixture of blood and feces, and mucus on the surface of the feces. hematuria is a common symptom of urinary tract cancer. The most terrible thing is painless hematuria, which is common in renal cell carcinoma, mainly manifested as repeated hematuria, swelling and pain on one side of the waist, etc.; the characteristic of ureteral tumor is repeated hematuria , the blood volume is sometimes more and sometimes less, and sometimes there are thin striped blood clots in the blood, accompanied by persistent low back pain; the characteristic of renal pelvic cancer is repeated intermittent hematuria, accompanied by swelling and pain on the waist.
Nose bleeding or blood in the nose, accompanied by tinnitus , headache, nasal congestion, etc., nasopharyngeal cancer should be highly suspected. Non-menorrhea in vaginal bleeding, especially in middle-aged and elderly women, and with abnormal leucorrhea in , you should be wary of cervical cancer .

Persistent pain in the upper abdomen, and the pain is related to the position. The pain is relieved when arching the waist or bent the lower limbs. You should be highly vigilant about pancreatic cancer . Unexplained pain in the bones and joints, accompanied by progressive weight loss, general fatigue and anemia, may be bone cancer or bone metastasis.
3. Reduce
. Diet and exercise have not changed, and the weight has dropped sharply in a short period of time, to a decrease of 10%. This is not a good phenomenon, maybe it is cancer coming.
4, lump
There is a lump in the breast or armpit. The lump is hard and difficult to push, and the skin of the breast has orange-like changes, which may be breast cancer . When the neck or head is cancerous, lumps will appear behind the ears, throat and under the jaw, accompanied by pain and difficulty swallowing, ear pain, chest tightness and shortness of breath, etc. If there is a lump in the mouth, accompanied by continuous non-healing oral ulcers, white spots or erythema of the oral mucosa, obvious foreign body sensation, throat pain, etc., you should be wary of oral cancer. I felt a lump on the abdomen, which had a hard and irregular texture. It may be tumors in the stomach, liver, pancreas, , etc.
5, burn
excludes fever caused by infection or immune diseases. The fever continues to fail to improve, which may be caused by tumors. Because tumor metabolites can follow the blood circulation, affecting the body temperature center, resulting in fever. Repeated burning sensation in the stomach is usually caused by excessive secretion of gastric acid, and may also be liver cancer or esophageal cancer.
Warm reminder
