I think it's fat, it is a tumor strange?

Review expert: Zhang Jianwei

When I want to ask contemporary people, I think, I think it should be when I go to the hospital for examination? For many people, "hospital visits" is a thing that is no less than a roller coaster and playing a secret room. The detection list can be put down on the road, and the big rock in my heart can be put down. But once there is a "special" symptom, in my heart, my heart can be in my heart. It seems like adding a big stone, and the rice is not fragrant.

Recently, Xiaobian saw such a news on the Internet. Ms. Cheng, in her 50s, has increased her belly in recent years. I thought it was getting fat, but I went to the hospital to check it. The mass! After diagnosis, this lump is diagnosed with fat sarcoma.

It can be seen from the news that fat sarcoma is a malignant tumor with a higher degree of malignant! The lipoma that is only a word from it is a benign tumor. These two kinds of tumors occasionally hear in daily life. What is the difference between them? Why is the name so similar, but the harm is so great?

What is lipoma?

Think about it, have you ever grown this kind of puppet? It feels soft and soft, and it will move. It usually does not have pain or itching. This kind of pimple may be lipoma.

Lipoma (Lipoma) is a kind of benign tumor accumulated from mature adipose tissue, mostly wrapped in fiber envelope. Its external manifestations are usually painless, round, soft -like dough, and can promote soft tissue masses. There are many growing parts of the lipoma, often appearing in the limbs and trunk, such as back, shoulders and necks, arms, and deep tissues. In theory, as long as there are parts of adipose tissue, lipoma may cause lipoma. The ultrasound of the lipoma is a uniform lump with echo, without obvious blood flow signals, and a fine line -like separation can be seen inside.

Lipoma is mostly 40 to 60 years old, and the incidence of men will be slightly higher than women. Why do you get lipoma? At present, the cause of lipoma is not completely clear. From the perspective of the onset, lipoma is mainly related to the body's fat metabolism, and adverse habits such as irregular diet and mental stress will affect fat metabolism and cause lipoma.

Many people feel that obese human fat is more fat, which is more likely to cause lipoma. In fact, this is wrong. In fact, lipoma is not exclusive to fat, and there is no study at present that lipoma and obesity are inevitable cause and effect. Most lipoma is secondary to endogenous adrenal corticosteroids and alcoholic liver disease. Inheritance, obesity, alcoholism, diabetes, etc. may be the cause of lipoma.

Lipoma is a benign tumor, which generally does not evolve into malignant tumors. In addition, it grows very slowly. If it does not affect daily life, it can be ignored; Or if there are obvious changes in the short term, you must pay attention to it, you need to go to the hospital for further observation.

Big secrets of fat sarcoma

Unlike lipoma, liposarcoma is a proper malignant tumor. A few liposarcoma will deteriorate from lipoma, but the probability is extremely low. Generally speaking, liposarcoma has nothing to do with lipoma, and clinical symptoms are obviously different.

Liposarcoma (Liposarcoma) is a soft tissue tumor that originated from the tissue of primitive lobe and consists of fat cells at different differential stages. The general position of fat sarcoma is relatively deep, the mass is infiltrated, the boundary is unclear, and it will spread to other areas. Sometimes the ultrasonic performance will have a blood flow signal.

From the perspective of histological types, there are a total of five types of liposarcoma. They are high-diversified liposarcoma (Well-Differentiated Liposarcoma), Dedifferentiated Liposarcoma, Pleomorphic Sabisarvan, and mucus-like. Myxoid LPS and small circular cytosarous sarcoma (Round-olled Liposarcoma). Among these five types, the most common is high -divide tissue sarcoma and dehuminoma lipous sarcoma.

Different types of liposarcoma have different histological characteristics. For example, high -divide fat sarcoma is low malignant, and high echo is mainly high in ultrasound. Polycipipipipipipipipipipipulansooredredred vulted vicious. High echo. They have common points in common that there are no obvious symptoms in the early days. Generally, after the tumor growth in the middle and late stages is large, it causes squeezing the surrounding tissue and organs, and then causes a series of clinical symptoms, such as compressing the gastrointestinal tract, abdominal pain, abdominal distension, diarrhea; Compression of the bladder can occur frequently, urgency, etc.

In the current medical methods, diagnosis of fat sarcoma is generally used in imaging examinations, including B -ultrasound, X -ray, CT scan and MRI. Because the liberal sarcoma is mostly after the peritoneum, the general diagnosis will determine whether the lump is located at the back gap of the peritoneal, and then further identify and formulate a treatment plan.

The treatment of liposarcoma is generally mainly surgery. Because it is a malignant tumor, the entire tumor will be removed as much as possible during surgery to achieve better treatment results. According to the need, such as the degree of malignancy of lipous sarcoma, there is a large risk of recurrence. Radiation therapy and chemotherapy will be adopted after surgery to reduce the local recurrence rate of patients and retain their physical function as much as possible.

With the continuous improvement of domestic medical levels, targeted therapy for fat sarcoma is also continuously improved and developed. In the "CSCO soft tissue sarcoma diagnosis and treatment guidelines" released in 2019, CDK4/6 inhibitors Palbociclib was recommended for the treatment of high -differentiated lipous sarcoma and dehuminating fat sarcoma after peritoneum.

The onset factors of liposarcoma are not clear. It occurs more than 40 to 60 years old and has no obvious gender differences. At present, liposarcoma does not have effective prevention methods. It is mainly recommended to prevent life and diet. Eat high -oil, high -fat food.

Speaking of which, are you more clear about lipoma and liposarcoma? All in all, whether it is a benign lipoma or a malignant liposarcoma, once the body appears, the most important thing is to seek medical treatment in time.
