Bladder cancer: frequent bloody urination, but no pain in urination, no effect of medicine.
Stomach cancer: long-term heart pain, bad appetite, nausea, vomiting, vomiting blood, black stool.
Nasopharyngeal cancer: long-term nasal congestion with tinnitus, headache, nosebleed, or unilateral painless submandibular swelling.
Esophageal cancer: eating with feeling of obstruction, sometimes vomiting, pain behind the sternum after eating but no other causes can be found.
Breast cancer: swelling of breast, blood and water coming out from nipple when squeezing, rough skin of breast like orange peel.
Hepatocellular carcinoma: chronic hepatitis, long-term stabbing or rising pain in the right upper abdomen, poor appetite.
Cervical cancer: irregular menstruation, increased leukorrhea with foul smell, small amount of vaginal bleeding after intercourse. Menopausal people have irregular painless bleeding.
Throat cancer: long-term hoarseness of voice, and medication does not help.
Lung cancer: long-term smoking, dry cough, blood in sputum, intermittent chest pain, dyspnea and fever, malignant cold.
Intestinal cancer: prolonged constipation, diarrhea, or alternating between the two, blood in stool, deformation, abdominal pain or feeling swelling, and unexplained anemia.
Self-examination of cancer:
1. Daily: pay attention to whether there is any change in the habit of stools, especially pay attention to whether there is any pain and falling sensation during stools, whether the shape of stools becomes thinner, and whether it is tar-colored or with blood. Pay attention to whether the ejaculation is shortened when urinating, whether there is white secretion discharged, whether there is blood in the urine, whether there is discomfort in the perineum, and so on. Women observe whether the leukorrhea is mixed with bloody discharge and whether it has a fishy odor.
2, monthly: touch the neck, armpits, groin, etc., check for enlarged lymph nodes (less than the size of a peanut is normal), the texture of the enlarged lymph nodes, whether or not they are fixed, whether or not they are swollen and painful, and the speed of growth. Note the black hemorrhoids on various parts of the body surface, whether they grow rapidly and break down in a short period of time. Men pay attention to the urethral opening with or without ulcerated nodules, the penis coronal groove with or without easy bleeding cauliflower-like swelling.
3, every year: a comprehensive physical examination by a professional physician or participate in a cancer screening.
Cancer screening:
Tumor screening, or screening, is aimed at detecting patients suffering from certain diseases in the population. Early detection of tumor cases
is mainly based on screening measures. Screening refers to the use of rapid tests, experiments, or other methods to classify an apparently healthy population into those who are likely to be ill (test-positive) and those who are likely to be free of disease (test-negative), and to provide a basis for inference about the detection of unrecognized diseases. Screening tests are not diagnostic. Those with a positive screening test must be further diagnosed and treated by a physician.
Tumor screening includes:
1. Physical examination by a physician.
2. Alpha-fetoprotein (AFP) for liver cancer screening.
3, Ultrasound. It is used to check abdominal tumors.
4, cervical smear cytology. This method has been fully recognized in cervical cancer screening. The diagnosis rate of cervical cancer is 95.5% in cervical smear-positive patients, and the diagnosis rate of suspected positive patients is nearly 70%.
5, fecal occult blood test, positive results of fiberoptic gastroscopy or barium enema. Used to check the digestive tract tumor.
6, line chest radiograph or fluoroscopy, sputum exfoliative cytology. As a method of lung cancer screening.
7, the census of breast cancer is firstly examined by women themselves, and the suspicious patients are found to be examined by physicians. Thermal image, mammography and other examinations can be used.
All in all, most of the current methods of tumor screening are not yet ideal and need to be further explored.
Actively treating precancerous lesions:
If heavy hyperplasia of vascular epithelium, atypical hyperplasia, chemosis and atrophic gastritis of gastric mucosa, chronic hepatitis and cirrhosis of the liver, colon polyps, hyperplasia and chemosis of bronchial epithelium are found, they should be highly valued and actively treated.
