Six signs to help you find invisible cancer

Many people find out they have cancer when it is already in the late stages. In fact, some small signs in life can help people detect those difficult-to-detect cancers.

If you keep catching a cold, beware of nasopharyngeal cancer

Experts point out that the early symptoms of nasopharyngeal cancer are not obvious and it is difficult to detect it early. If you have nosebleeds and some cold symptoms, such as runny nose and coughing up phlegm, and they don't go away, or if you don't often catch colds but have colds repeatedly, you should be alert and go to the hospital for examination as soon as possible. When swollen lymph nodes cause nasal congestion or affect vision, the disease has usually developed to the middle or late stages.

The kidneys are located in the posterior abdominal cavity, which has a large space, and diseases related to this are not easy to detect in the early stages. Experts] remind that if you find hematuria, lower back pain, or abdominal lumps, you should be careful about kidney cancer and undergo further examination as soon as possible. In addition, people who like to take painkillers or often dye their hair may be at high risk of kidney cancer and are advised to undergo regular urine tests and ultrasound examinations. Frequent hair dyeing is not only related to kidney cancer, but also to bladder cancer. This is because the dye will be metabolized through the urinary system. If it accumulates in the kidneys and bladder for a long time, it may stimulate cancer cell changes.

Experts point out that when many people find that they cough up blood or go to the hospital for examination due to symptoms such as chest pain and difficulty swallowing, they are most likely already in the late stage of lung cancer. If people have a history of smoking and have a persistent cough, they should go to the hospital.

Experts point out that if you experience upper abdominal distension, or persistent unexplained abdominal pain or even back pain, there is nothing wrong with a gastroscopy or liver and gallbladder ultrasound; especially if you lose weight inexplicably without deliberately dieting, you should be alert to pancreatic cancer.

Women should seek medical attention promptly if they experience lower abdominal swelling, dull pain, pelvic or abdominal pain, a feeling of fullness quickly, frequent urination, and urgency to urinate, and if any of these symptoms occur almost every day. In addition, tumors may sometimes compress the large intestine, so changes in bowel habits can also be a warning sign.

Experts say that if symptoms such as heavier menstrual bleeding, bleeding after menopause, or irregular menstruation occur for more than three consecutive months, there is a possibility of precancerous conditions such as endometrial hyperplasia.
