People often talk about cancer, but it is not completely invincible. Recently, the website “Men’s Health” published the alarm signs of 6 types of cancer that are most likely to attack men and the false warning symptoms that can easily confuse people, reminding them to correctly determine the signs of cancer in the first place. Prostate cancer False alarm: Many people think that frequent urination, urgent urination, slow urination and incomplete urination are related to prostate cancer. But in fact, it may just be a symptom of prostate enlargement or urethral stricture. Early Signs: The best way to diagnose prostate cancer early is still finger palpation and prostate-specific antigen testing. Finger palpation is one of the main tests that can detect prostate cancer if the prostate is enlarged, hardened, nodular or irregularly shaped. If the prostate-specific antigen is elevated or changes a lot, a prostate cancer biopsy should be performed. Lung cancer False alarm: Many patients diagnosed with lung cancer have a history of “pneumonia” and the early symptoms of both are similar, such as fever, cough, sputum, and a shadow on chest X-ray. Early signs: Many people will mistake lung cancer as pneumonia and miss the best treatment time. Therefore, while focusing on symptoms such as coughing, coughing blood and chest pain, pneumonia patients, after 4-6 weeks of treatment, should have another chest X-ray to clarify the condition. This is especially true for patients who develop symptoms of chest pain without exercise. Colon cancer False alarm: Bleeding during bowel movement, bright red blood, will stop on its own after bowel movement and no pain is felt. This is indeed not colon cancer, but a symptom of hemorrhoids. Early signs: It is still important to pay high attention to blood in the stool, even if there has been blood in the stool once, it should never be ignored. If it is colon cancer, it is often blood in stool mixed with mucus or pus, and the color of this blood is darker than hemorrhoid bleeding, and it is often combined with diarrhea. At this time, colonoscopy must be done in time to detect the problem early and treat it urgently. Bladder cancer False alarm: Symptoms of bladder irritation or pain in the urethra are most likely due to infectious diseases of the urinary tract. Early signs: Blood in urine. Most bladder cancers occur mostly in the mucosa lining the bladder and can still be cured if caught early. Lymphoma False alarm: In fact, it is not necessary to be alert to lymphoma whenever the lymph nodes appear swollen, as ordinary people think. Swollen lymph nodes in the mouth, nasopharynx, lower extremities and after infection of genital organs are not symptoms of the disease. Early signs: swollen lymph nodes in the neck, armpit or groin without pain. Unexplained weight loss within a month or two and painful lymph nodes after drinking alcohol are important signs to look for. Generally infected lymph node swelling that does not subside within a week should also be examined carefully at the hospital. Blood tests can sometimes reveal some abnormalities, but the most thorough test is a biopsy of the lymph nodes. Melanoma False alarm: Brown, hard epidermal patches of seborrheic keratosis on the body that usually do not fade on their own are usually benign, with very few malignant changes. Early signs: Skin plaques with malignant qualities will be prominent, change in color, often with jagged, jagged edges, and an unsmooth surface. It is sometimes accompanied by oozing, bleeding, itching and pain.
