Angiosarcoma develops from the cells that make up the walls of blood vessels. It can occur anywhere throughout the body but most commonly in the skin, breast, liver, spleen, and in the deep tissues of the body. Angiosarcoma in the skin is often found on the face and scalp.
Bone sarcoma is a cancer that starts in the bone. Sometimes a bone sarcoma is called a primary bone cancer. It is uncommon, with an average of about 670 diagnoses in the UK each year.
Chondrosarcoma is a bone sarcoma that develops in the cartilage cells. It mostly affects adults above the age of 40 and the most common sites are the upper arm, pelvis and thigh bone. They make up 37% of all bone sarcoma diagnoses.
Desmoid-type fibromatosis (DF) is sometimes called Desmoid Tumour or aggressive fibromatosis. It is a rare type of benign (non-cancerous) tumour. DF develops from fibroblasts. These are a type of cell that provide cell support for the body’s tissues.
Fibroblastic sarcoma develops in the fibrous tissues within the body. It is most commonly found in the limbs, skin (dermofibrosarcoma) and in the trunk.
GIST is a type of sarcoma, rare cancers that develop in the connective tissues: muscle, bone, nerves, cartilage, tendons, blood vessels and the fatty and fibrous tissues.
Giant cell tumours (GCT) are benign (non-cancerous) tumours that develop in the bone. They mostly occur in the long bones found in the arms and legs. They are always found at the end of the bone next to the joint.
Gynaecological sarcomas, sometimes shortened to gynae sarcomas occur in the female reproductive system: the uterus (womb), ovaries, vagina, vulva and fallopian tubes. You may also hear the term uterine sarcoma. They can affect women of any age.
Kaposi’s sarcoma is a rare type of cancer that affects the skin, mouth and occasionally the internal organs.
Leiomyosarcoma develops in the smooth muscle cells, which are sometimes called involuntary muscles because they cause organs to contract without our control.
Liposarcoma develops from the fat cells found all over the body. It can occur anywhere throughout the body but most commonly on the trunk, limbs and in the retroperitoneum.
MPNSTs, also known as neurofibrosarcomas, develop in the cells that cover nerves. They can occur anywhere throughout the body. MPNSTs occur mainly in adults.
Osteosarcoma is a type of bone sarcoma mostly diagnosed in teenagers and young people; however, it can also affect older adults. It mostly affects the knee, thigh bone, shin bone or upper arm. They make up 30% of all bone sarcoma diagnoses.
Retroperitoneal sarcomas occur in the retroperitoneum. This is an area behind the peritoneum, the lining of the abdominal space that covers the abdominal organs. The retroperitoneum is deep in the abdomen and pelvis, behind the abdominal lining, where organs such as the major blood vessels, kidneys, pancreas and bladder are located.
Rhabdomyosarcoma develops in the skeletal or voluntary muscles of the body – the muscles we can control ourselves. It is most commonly found in the head and neck but it also occurs in the abdomen. This is a rare type of sarcoma that affects more children than adults.
Ewing’s sarcoma usually affects the bone; however, this type develops in the soft tissue around the bone. It is sometimes called extra osseous sarcoma – extra means outside, osseous means bone. They are found in the trunk, limbs and the brain.
Soft tissue sarcomas develop in supporting or connective tissue such as the muscle, nerves, tendons, blood vessels and fatty and fibrous tissues.
Synovial sarcoma develops in cells around joints and tendons. Synovial sarcoma can occur anywhere throughout the body but often near the knee. Synovial sarcoma is most commonly associated with young adults.
