Four types of polyps may become cancerous
Four types of polyps may become cancerous. Polyps have a certain possibility of recurrence, so after surgical resection, patients also need to be reviewed regularly.
When the word “tumor” is mentioned, everyone will first think of a fatal disease: cancer!
But in fact, there are two major types of tumors in clinical classification. The first is benign tumors, that is, tumors that do not have the characteristics of infiltration and metastasis.
The second type is malignant tumors, which refers to solid malignant tumors that appear on human organs, which have the characteristics of infiltration and metastasis, which are commonly known as cancers. Benign and malignant tumors are essentially different in clinical practice!
For example, “polyps” that appear on hollow organs are typical benign tumors. For the human body, polyps may grow from the nasal cavity to the vocal cords, from the gallbladder to the intestines, and even the cervix. It should be noted that although polyps are benign lesions, some of them have the tendency and possibility of malignant transformation!
The following four types of polyps may become cancerous in the future:
1. Adenomatous polyps
If the types of polyps are divided into two categories, they are adenomas and non-adenomatous polyps. Adenomatous polyps are the ones with the highest cancer rate among all types of polyps. There are mainly three common adenomas in clinical practice, namely tubular adenoma, villous adenoma and mixed-like adenoma.
Among the three, tubular adenomas are the most common, with relatively low canceration rate. The villous adenoma and mixed-like adenoma contain a large amount of villous components, so the cancer rate is relatively high. Among them, the carcinogenesis rate of villous adenoma within 10 years can even reach about 70%.
2. Family hereditary polyposis
Colorectal cancer shows a typical tendency of family clustering in clinical practice. The reason for this is directly related to hereditary adenomatous polyposis. But this is not because the next generation is born with the disease, but the next generation is affected by genes. This is an autosomal dominant genetic disease.
When the next generation carries this gene, they may develop the disease during adolescence, and they are mostly polyps. If the development of the disease is not detected and intervened in time, the late cancer rate of hereditary adenoma is almost equal to 100%.
3. Polyps with too large diameter
There is no doubt that adenomatous polyps have a cancerous rate. However, not all adenomatous polyps will undergo malignant transformation. From a clinical point of view, besides its texture, the diameter of polyps is also very important. Under normal circumstances, the smaller the diameter of polyps, less than 1cm, the lower the cancer rate.
If the diameter of the polyp is too large, more than 1cm, or even more than 3cm, the cancer rate will increase rapidly in the later stage, reaching about 50%.
One more thing to note here is that even if a polyp with a larger diameter is not cancerous, it may cause obstruction of the hollow organs and induce inflammation, pain and other problems.
4. Multiple polyps
Most benign polyps are single growths, and 1 to 2 small polyps may appear in the cavity organs. On the contrary, multiple polyps, even dozens or hundreds of polyps, appear in the cavity organs. This is a typical polyp, and adenoma is the most common type of polyp.
From a clinical point of view, even the diameter of multiple polyps is very small, and the late cancer rate is quite high. Nearly 90% of all colorectal cancer patients in some countries have developed from multiple polyps.
In general, the above four types of polyps are the ones with the highest cancer rate among all types of polyps. Therefore, no matter where these types of polyps appear on any organ of the body, they need to be checked by a doctor in time, and surgery is required if necessary.
In addition, polyps have a certain possibility of recurrence, so after surgical resection, patients also need to be reviewed regularly.
