What Is Liposarcoma?


Liposarcoma is a type of cancer that starts in the fat cells of your body. It is a very rare cancer that affects tissues like nerves, muscles, tendons, or fat. Furthermore, the tumor may cause pain and swell at the site where it occurs.


Liposarcoma is usually of five types_Well-differentiated liposarcomas, Myxoid liposarcoma, Round cell liposarcoma, Dedifferentiated liposarcoma, and Pleomorphic liposarcoma.


Well-differentiated liposarcoma grows very slowly and is the most common type. Usually, it doesn’t spread to rest portions of the body. Myxoid liposarcoma grows faster than the prior one and is 2nx the most common type. Moreover, it tends to spread to other parts and causes problems.


Round cell liposarcoma affects the arms or legs usually and grows at a faster rate. While Dedifferentiated liposarcoma is when your slow-growing tumor begins to grow faster. Pleomorphic liposarcoma is not a very common form, but spreads very quickly. Liposarcoma can happen at any age, but it’s most common between ages 50 and 65.




It is not exactly clear what leads to liposarcoma. However, researchers do know that these tumors develop because of the changes in DNA called mutations. In this process, your fat cells develop irregular changes which lead to cancer.


However, certain things increase your chances of developing a liposarcoma. For instance, some rare genetic diseases can be a risk factor for this cancer.  Similarly, a family history of liposarcoma can also make you more prone to cancer.



A liposarcoma can develop in any area of your body having fat cells. However, it usually affects the fatty areas of your belly and legs.


At first, you may not find your tumor to be painful or sore. However, as your tumor grows continuously, various problems start. For instance, your liposarcoma may push against various organs like the stomach if it starts in the belly.


Depending on the location of your tumor, a liposarcoma may cause:


Presence of a lump beneath your skin. It usually develops on your thighs or around your knees.

Swelling and pain.

The weakening of your arm or leg lumping.

As soon as you start eating, you feel full


Black or even bloody stool

Vomiting with blood


Your belly becomes larger.

How your doctor diagnoses the liposarcoma.


Before ordering you for imaging tests, your doctor will ask about general health. He/she will perform a thorough physical check-up. If they suspect the liposarcoma, they will order for other tests like:


Imaging tests. To see the size and scope of your tumor, your doctor will order for CT scan or MRI. These tests give additional detail about soft tissue tumors like a liposarcoma.


Biopsy. This test helps confirm the liposarcoma if your doctor suspects the tumor. In this procedure, he/she is going to take a small tissue sample from your tumor. Then, he/she will see this tissue under a microscope. This way they can detect your tumor.




Depending on the location of a tumor, its size, and type, treatment options may vary from person to person. Surgery is useful in which your doctor will try to remove the tumor. This is the most common form of treatment for this cancer.


However, if the tumor is growing continuously, your doctor may go for other treatment options. This is also necessary when your doctor cannot remove the tumor Surgically. In that case, radiation therapy or chemotherapy becomes essential to kill all the remaining tumor cells.


In certain cases, your doctor may use chemotherapy or radiation therapy to shrink the tumor size before surgery. Thus, you should ask your healthcare provider about clinical trials with patients suffering from liposarcoma.

These studies help to find whether these therapies work and whether they are safe. This way your doctor may inform you whether these therapies are good for you or not.
