Oncogene Addiction: How Cancer Cells Can Become So Aggressive

Bone cancer is an aggressive, yet rare form of cancer that makes up less than 1% of all people who are diagnosed with cancer.Patients with bone cancer face significant challenges when it comes to cancer diagnosis and treatment due to the tumor's rich microenvironment and heterogeneity.This review provides a comprehensive overview of bone cancer, starting with foundational mechanisms like DNA replication and the cell cycle, detailing how specific genes like tumor suppressors and oncogenes create errors and dysregulation in these processes, aiding in the formation of malignant tumors.With 500,000 people battling this complex cancer, it is important to understand the mechanisms of how it can form and metastasis in order to figure out new ways of diagnosing and treating patients more effectively. An Overview of Primary Bone Cancers: Focus on Osteosarcoma and Related MalignanciesIn 2025 alone, 2.04 million new cancer cases were reported, and an estimated 618,120 currently diagnosed patients are expected to die from this disease (1).Cancer is the uncontrolled or abnormal growth of cells that can occur anywhere in the body.Cancerous tumors can be found in various states, such as solid tumors, found within an organ, or blood cancers, found within the lymphatic system or bone marrow (2).Cancer is most prevalent in areas with a high tissue concentration, such as the breast and skin, but is least common in compacted and highly structured cells, like those found within the bones.Bone cancer makes up only 1% of the cancer diagnoses worldwide, making cases extremely rare, with a limited number of cases to study.Osteosarcoma is the most prevalent type of bone cancer, with around 3,770 cases diagnosed each year (3).This cancer primarily affects those between the ages of 10 -30, and also tends to affect more males than females.This age group is most affected because osteosarcoma is found during the early formation of bone cells, a process that declines with age
