According to the statistics of the Ministry of Health, the incidence rate of malignant tumors in China has been rising year by year in recent years, among which lung cancer is growing at an annual rate of 26.9%. In fact, many tumors can be detected at an early stage so that more than 80% of cancers can be cured. Why are early tumors seldom detected? In addition to the symptoms are not obvious, mainly because there is often a long process of tumor formation. It often takes nearly 10 years for a normal cell in the human body to evolve into a tumor with a diameter of 0.5 cm. A typical case is gastric cancer, which may only be chronic superficial gastritis at the beginning, without obvious symptoms such as stomach pain and bleeding. So it is hard to draw attention to it. Once the cancer cells break through to the submucosal layer, it will develop very fast and metastasize in a short time, and at this time, the opportunity of treatment has been lost. Eleven kinds of body symptoms can identify early tumors 1. At least once a month, you should touch your neck, armpit and groin to check whether there are enlarged lymph nodes (it is generally believed that lymph nodes smaller than the size of a peanut are normal), what is the texture of the enlarged lymph nodes, whether they are fixed or not, and whether there is any pressure and pain. 2.When coughing for a long time, you should pay attention to whether there is blood mixed in the sputum coughed up, pay attention to the time of coughing, the part of chest pain, the amount of blood, the color of blood, etc.. 3, loss of appetite and lethargy, epigastric pain, if accompanied by nausea and vomiting, pay attention to whether there are black-brown contents in the vomitus, pay attention to observe whether the stool is tarry or with blood.

When urinating, observe whether there is white secretion discharge, whether there is hematuria, and whether there is discomfort in the perineum. 7, long-term hoarseness, should look in the mirror, open the mouth and take a deep breath, observe the throat with or without enlarged tonsils and other swellings. 8, men should pay attention to whether the foreskin of the penis is too long, whether there is an ulcerated nodule at the urethral opening, whether there is an ulcerated nodule in the coronal groove of the penis, and whether there is an easy-to-bleed cauliflower-like swelling in the coronal groove of the penis. 9.When the fever is of unknown cause for a long time, attention should be paid to the measurement of body temperature; if necessary, the blood routine, blood sedimentation and so on to do further examination. 10, after strenuous activities and limb pain and activity restrictions, should pay attention to the joints of the limbs with or without swelling, whether the subcutaneous palpable swelling. 11. Pay attention to the changes of moles on the surface of the body at any time. Cancer screening should be done regularly to nip the disease in the bud. The Physical Examination Center has formulated scientific physical examination packages for various types of cancer screening, which is convenient for you to choose the examination items reasonably when you undergo cancer screening.
