If you suspect that you have cancer, how can you determine whether you have cancer?

Today's society is a bit "talk about cancer discoloration", if you find that the people around you, whether they are relatives, friends or colleagues and classmates, found cancer, plus recently have some discomfort in the body will think that they also have cancer? So often some netizens ask how to know if they have cancer?

In fact, the final diagnosis of cancer is pathological diagnosis, and pathology is the gold standard for cancer diagnosis. Clinically, some "clues" are found through some of the patient's symptoms, signs, laboratory or imaging tests, and then pathological examination is done according to these "clues" to determine whether it is the "real culprit".

In life, how should we find these "clues", and then "follow the vine to find the melon" through various methods to test, and provide to the doctor, let the doctor verify whether it is cancer. When our body will more or less appear some abnormal signs and symptoms, we need to pay attention!

First, nodule problems common are breast nodules and lung nodules, breast nodules if the ultrasound BI-RADS score below level 3 needs regular review, ultrasound BI-RADS score 4 or above needs to be puncture biopsy needs to clarify the pathological diagnosis. For nodules with lung nodules less than 6 mm, often benign nodules, it is recommended to review CT after 1 year to see if there is a change; 6-8 mm nodules, it is recommended to review once every 6 months to see if there is a change, such as no change 1 year to review CT again; nodules larger than 8 mm, the chance of malignancy is higher, about 3 months to recheck CT, if the nodule is accompanied by the appearance of lobes, burrs and or pleural depression, biopsy is required.

Second, unexplained weight loss in a short period of time, and to rule out the problem of diabetes or thyroid disease, it is necessary to be particularly vigilant about the possibility of cancer.

Third, some diseases cannot be cured for a long time, such as coughing or sputum with blood in the long-term incurable cough, and suctioning sputum with blood. No ulcers occur on any part of the body due to trauma, especially if they do not heal for a long time.

Fourth, the change of living habits For example, the original defecation once a day has now become a defecation several times a day or a few days, or the time point of defecation has changed, or there is a feeling of incomplete defecation and tenesmus. Then there is a change in traits, such as stool suddenly becoming out of shape or suddenly constipation, or a change in shape, such as thinning, flattening or grooves, or stool with some abnormal substances, such as mucus or bloody substances. Or some menopausal patients, they suddenly come to "menstruation", they need to pay great attention to.

Fifth, the physical examination found that the tumor markers are elevated If the tumor markers are elevated, if it is slightly elevated, it is necessary to rule out whether there are other diseases such as inflammation and damage, such as liver cancer markers are AFP, hepatitis patients will also lead to a rise in liver cancer markers. If it is found that the elevation is particularly high, several times the normal value, it is necessary to be careful, it may be cancer, and it needs to be systematically examined.

It should be noted that most of the current early cancer, there are no obvious symptoms, if there are symptoms, generally in the middle and advanced stages, so according to their actual situation, such as smokers over 40 years old people should regularly do low-dose spiral CT regular physical examination, love to drink small pot friends, to regularly do abdominal ultrasound and AFP examination so as to confirm whether they have cancer.
