Abstract

Pelvic bone cancer, also known as pelvic sarcoma, is a rare type of cancer that affects the bones of the pelvis. The pelvis is the large bone structure located at the base of the spine, which includes the hip bones, sacrum, and coccyx. Pelvic bone cancer can arise from any of these bones and can be either primary or secondary. Primary pelvic bone cancer is cancer that originates in the pelvic bones, whereas secondary pelvic bone cancer is cancer that has spread to the pelvic bones from other parts of the body. The most common primary bone cancer that affects the pelvis is osteosarcoma, which is a cancer that arises from the bone-forming cells. Chondrosarcoma is another type of primary bone cancer that can affect the pelvis, which arises from the cartilage-forming cells.
