Five words of cancer signal
Cancer is indeed a relatively difficult disease to treat under the current level of medical research. However, difficult to treat is not the same as incurable, and with the development of medical technology, the means of treating cancer are also progressing, and various treatment methods such as surgery, radiotherapy, chemotherapy and biological therapy make the chance of cancer being overcome much higher. Experts remind that early detection, early diagnosis and early treatment are crucial for cancer patients. The early warning signs of cancer are summarized into the “five words of cancer signal” which are easy to remember, namely: blood, block, pain, burning and reduction.
1. Bleeding
Except for normal menstruation in women, any unexplained bleeding from any organ that persists for a long time may be an early warning signal of cancer.
(1) Unexplained nasal bleeding (excluding transient nasal bleeding caused by trauma, external force, dry weather or high blood pressure) may be nasopharyngeal cancer, blood disorders, etc;
(2) Coughing up blood, blood in sputum (excluding temporary bleeding caused by dry weather or overwork), which may be manifestation of lung cancer;
(3) Blood in urine, especially painless hematuria, may be bladder cancer or kidney cancer;
(4) Blood in stool, if accompanied by change in bowel habits, urgency and heaviness (abdominal pain and embarrassment, needing to defecate at times, heavy anus and unpleasant bowel movements), may be the early manifestation of colorectal cancer;
(5) Bloody discharge from female nipples may be breast cancer or breast duct tumor;
(6) Vaginal bleeding after menopause may be a manifestation of cervical cancer.
2.Abnormal lumps
(1) Lumps appearing on superficial parts of the body that do not disappear for a long time or increase rapidly within a short period of time, usually cancerous tumors are often irregular lumps;
(2) Bilateral asymmetry of the breast, irregular lumps and orange peel-like changes may be a sign of breast cancer;
(3) goiter, sudden inability to make voice or voice suddenly becomes hoarse, in addition to looking at thyroid, you should also visit oncology department to avoid thyroid cancer or laryngeal cancer from being missed.
3. Pain
Pain that continues to worsen for a long time may be an early sign of cancer.
(1) Progressive increase of headache with nausea and vomiting (jet vomiting is more critical) and blurred vision may be a sign of brain tumor or brain metastasis of lung cancer;
(2) Pain, pressure, tightness and stiffness in the neck and facial edema, which may be caused by the obstruction of blood return due to the compression of superior vena cava by the tumor;
(3) Burning sensation behind the sternum, unpleasant swallowing and pain, which may be the manifestation of esophageal cancer, cardia cancer and stomach cancer.
4.Fever
Continuous fever, especially low fever, children should be alert to hematological system tumor, and adults should be alert to the possibility of liver cancer, kidney cancer and other tumors.
5.Weight loss
Short-term unexplained weight loss and progressive decline (excluding hyperthyroidism and diabetes) may be a tumor; if weight loss is accompanied by yellowish skin color and pain, active examination should be conducted to exclude the possibility of pancreatic cancer and other tumors.
