What is the pathological examination for oral cancer?

1. Local incision biopsy, for example, when the patient has a large white plaque, I don't know what the white plaque is, usually a small piece can be taken at the junction of the white plaque and the surrounding normal tissues and sent to the pathology department for pathological diagnosis;

2. Excision tissue biopsy, for example, when the white plaque is small, the whole piece can be cut off, so that the damage is not particularly large, and it can be sent to the pathology department for the diagnosis of local tissue extraction;

3. When the tissue is large and does not want to be diagnosed by biopsy, intraoperative freezing can be done. This condition is usually used when the patient is suspected to be malignant, or the examination results are more likely to be bad, and the doctor's local excision tissue biopsy and local excision tissue biopsy are in the same condition during the operation, and it needs to be sent to the pathology department, which will issue a frozen report in about 20-30 minutes. The cryo-report is a rapid intraoperative diagnosis that allows for a short period of time.

Since the fixation and treatment of tissues are not as well reported as routinely reported, the accuracy of freezing reports is low, with an accuracy rate of 90%-95%. According to the intraoperative freezing report, the surgeon needs to perform the next step of surgical treatment, if it is malignant, the next step of expansion or dissection according to the malignant method, if it is benign, then local excision.

Oral cancer, including maxillofacial cancer, is one of the more common cancers. In the early stage of oral cancer, it is often bitter and not easy to attract the attention of patients, or although patients find some abnormalities, they hope that they can disappear on their own. The best way to get oral cancer is surgery.

However, when oral cancer is diagnosed, the best time for surgery is often missed. In this case, even if surgery is possible, the large area of surgery will cause damage to the oral cavity and will not be able to restore normal function and form. Therefore, early detection has become an important prerequisite for oral cancer.

Self-examination is a simple and effective way to detect D-cavity cancer at an early stage. This self-examination should be done regularly and frequently. You can do the microscopic examination alone, or you can ask someone else to help you check it.

In particular, older men who smoke and drink regularly, as well as those who wear bad prostheses (dentures) in their mouths, should have regular self-examinations as follows:

1.Examination of the face and neck When examining the neck, tilt your head back as much as possible to check for abnormalities in the mandible area and neck; Then touch the left and right sides of the neck and mandible area with your hands to see if there is a difference between them. 2.

Check your lips Look at the outside of the upper and lower lips with your eyes and touch them with your hands. Then use your thumb and index finger to pull the lower lip down to check the inside and finally the inside of the upper lip. 3.

Check your gums Pull your open lips to check your gums and touch them with your index finger to see if they are the same as they were when you last examined. 4.Check the cheeks Close your mouth gently, place your thumb and forefinger at the corners of your mouth and pull them outward, look with your eyes, and touch the side of your cheek with your hands to see if there is anything abnormal.

5.Check for tongue cancer Stick out your tongue, grasp your tongue with gauze on your hand, observe and touch the surface of the tongue, and pull your tongue to the left and right sides to observe both sides of the tongue. 6.

Check the bottom of the tongue Raise the tongue as high as possible against your arm, observe and touch the bottom of the tongue to check for abnormalities. 7.Check the pharynx and palate to make an "ah" sound, and observe the pharynx in a bright place; Then tilt your head back slightly and observe and touch the palate.

When you find any of the following abnormalities during a self-examination, it is best to have an experienced specialist examine them to be sure and promptly.

Suggestion: Hello, in the early stage of oral cancer, it is often bitter and not easy to attract the attention of patients, or although patients find some abnormalities, they hope that they can disappear on their own. However, when oral cancer is diagnosed, the best time for surgery is often missed.

Therefore, early detection has become an important prerequisite for oral cancer. Self-examination is important, either through a microscope or with the help of someone else. If the following abnormalities are found during self-examination, it is best to consult an experienced specialist to confirm ** and promptly**.

1) There are lumps and nodules;

2) Those with white, smooth scaly plaques, 3) red plaques, ulcers, inflammatory areas and other symptoms that cannot be healed for a long time;

4) recurrent bleeding in the mouth for no apparent reason;

5) numbness, burning or dryness in the mouth without obvious cause;

6) Difficulty or abnormality in speaking or swallowing.
