👉 Osteosteatoma is a type of cancer that primarily affects bones, specifically the long bones such as the tibia and fibula. It is also known as bone sarcoma or osteochondroma. In this condition, the cells in the bone are abnormal and begin to grow uncontrollably, causing the bone to become weaker and more susceptible to fractures. This can lead to a loss of bone density and eventually lead to cancerous growths within the bone tissue itself.
