What you need to know about: Bone Cancer. By: Mrs. Boggs. Bone Cancer. Bone cancer is cancer that arises first in the bone. True bone cancer is called osteosarcoma Bone is often a secondary site of metastases for other types of cancer such as prostate cancer, lung cancer, breast cancer, etc.

  1. What you need to know about:Bone Cancer By: Mrs. Boggs

  2. Bone Cancer • Bone cancer is cancer that arises first in the bone. • True bone cancer is called osteosarcoma • Bone is often a secondary site of metastases for other types of cancer such as prostate cancer, lung cancer, breast cancer, etc.

  3. Risk Factors • The exact cause for bone cancer is not known, but there are many risk factors for the disease; some can be avoided while others can not. • Risk factors include: • Smoking • Age • Race • Having other diseases such as retinoblastoma • Treatment with radiation

  4. Normal Cell Cycle Cancer Cell Cycle Divide without appropriate signals Can continue growing even though they are in contact with other cells Cells continue through the cell cycle without the “all clear” signal from the checkpoint regulators Biology of Cancer

  5. One of the leading causes of bone cancer is radiation Radiation results in: Point mutations Chromosomal damage Break DNA DNA Damage • Point mutations occur when bases in DNA are changed • There are different types of point mutations including: • Nonsense • Missense • Frameshift

  6. Surgery Removes the tumor mass from initial location Radiation Therapy Uses high energy waves targeted to cancer growth Waves cause damage within the cell, disrupt cellular processes, prevent accurate cell division, and cause the cell to die Death of cells causes the tumor to shrink Treatment

  7. Prevention • There is way to truly prevent bone cancer • General cancer preventions include: • Diets low in fat • Exercise • Eat lots of fruits and vegetables • Do not smoke • Limit consumption of alcoholic beverages • Limit UV radiation
