Cancer is a very common disease today, and if it is detected early and diagnosed early, most patients may be able to obtain a radical cure. However, most of the patients seen in clinic are not early stage cancer. Cancer often has no special symptoms or discomfort in the early stage, and once the symptoms appear, it is often at an advanced stage. How to detect cancer at an early stage? In fact, there are some symptoms and signs that may be related to early cancer, which we call “early signs” or “warning signs”. The government attaches great importance to the early detection of cancer and recommends screening through medical checkups. However, it also depends on our vigilance and learning to self-examine and self-discovery. Eight warning signs: early signs of cancer 1. Hard nodes or hard changes can be palpated, such as hard nodes found in the breast, skin and tongue. 2.Warts (superfluous tumors) or moles with obvious changes. 3.Persistent digestive abnormalities. 4.Persistent hoarseness, dry cough and difficulty in swallowing. 5.Unusual menstrual period, heavy bleeding, extra-menstrual bleeding. 6.Unexplained bleeding from nose, ear, bladder or intestine. 7.Wounds that do not heal, swelling that does not go away. 8.Unexplained weight loss. Symptoms: According to the situation in China, the Chinese Academy of Medical Sciences has proposed the following symptoms as warning signs to draw attention to cancerous swelling: 1.Lumps in any part of the body, such as breast, neck or abdomen, especially if they are gradually increasing in size. 2.Ulcers developed and born without trauma on any part of the body, such as tongue, cheek mucosa, skin, etc., especially those that do not heal for a long time. 3.Irregular vaginal bleeding or discharge (commonly known as increased leucorrhea) in women of middle age or older. 4.Dullness, burning pain, foreign body sensation or progressive aggravation of dysphagia behind the sternum when eating. 5.A dry cough or blood in the conversation that cannot be cured for a long time. 6.Long-term indigestion, progressive loss of appetite, wasting, and no clear cause is identified. 7.Change in stool habit or blood in stool. 8.Nasal congestion, epistaxis, unilateral headache or diplopia. 9.A sudden increase in size of the nevus or breakage, bleeding, or loss of the original hair. 10.Painless hematuria. 11.Tumor-related signs unilateral persistent worsening headache, vomiting and visual disturbance, especially diplopia of unknown cause. 12.Tinnitus, hearing loss, retractable sputum with blood, neck mass. 13.Unexplained oral bleeding, oropharyngeal discomfort, and foreign body sensation. 14, Painless and persistent worsening jaundice. 15, Nipple overflow, especially bloody fluid. 16.Growing gynecomastia. 16.Unexplained fatigue, anemia and fever. 17.Unexplained generalized pain, bone and joint pain. Please note that neither the eight warning signs, ten symptoms nor any of the signs related to tumor are exclusive to cancer. Having one or even several of these items does not mean that one is suffering from cancer. This is because some benign diseases also have these conditions. These signs should not be considered as the basis for cancer diagnosis, and the presence of one or a few signs should not be taken as a cause of panic and anxiety for the whole family. However, the warning signs and symptoms mentioned above may be the early signs of some cancers, and if they are taken lightly, diagnosis and treatment may be delayed. Therefore, it is recommended to have frequent health checkups and to seek consultation with experienced doctors when you get the report of medical examination findings. If you have any questions, you should contact your oncologist for consultation to get a diagnosis as early as possible, and also to gain general health knowledge.
