Description
Bone Cancer Awareness: Know the Signs aims to educate the public about early symptoms of bone cancer, such as persistent bone pain, swelling, or fractures. Recognizing these signs early is crucial for timely diagnosis and treatment, which can significantly improve patient outcomes. The campaign emphasizes the importance of regular check-ups and consultations with healthcare professionals if symptoms persist. By raising awareness, it seeks to reduce the stigma and fear associated with bone cancer, encouraging more people to seek medical advice promptly. Early detection can lead to more effective treatments, better management, and increased survival rates.
Résumé
- Bone cancers are rare, with most tumors in bone being metastatic from other sites like breast or prostate. Primary bone cancers account for less than 1% of all new cancer diagnoses but are aggressive, particularly in children. Early diagnosis is crucial to prevent metastasis and improve patient survival.
- Primary bone cancers originate from bone cells like osteoblasts, osteoclasts, or cartilage. Bone tumors are categorized as benign or malignant. Benign tumors are well-defined with circumscribed borders, while malignant tumors have irregular borders and invade surrounding structures.
- Benign lesions are circumscribed and don't invade nearby structures, whereas malignant lesions can metastasize. Common benign and malignant bone tumors have predilections for different areas of long bones, like the diaphysis, metaphysis, or epiphysis.
- Common benign bone tumors are osteochondromas and osteoid osteomas, while osteosarcomas, chondrosarcomas, and Ewing sarcomas are the most common malignant tumors. Benign tumors are generally surgically removed, whereas malignant tumors often require additional treatments such as chemotherapy and radiation.
- Risk factors for bone tumors include specific syndromes like Li-Fraumeni or prior radiation therapy. Symptoms include pain and swelling, and advanced cases may present with weight loss, fatigue, fever, or bone fractures. Diagnosis involves X-rays, MRI, CT scans, bone scans, PET scans and biopsy for confirmation.
- Osteosarcoma is the most common primary malignant bone tumor, typically affecting individuals aged 10-25, with males more frequently affected. Ewing sarcoma, characterized by a chromosomal translocation, is most common in children and young adults. Chondrosarcoma is more prevalent in middle-aged and older adults and can develop from benign cartilage tumors.
- Treatment options vary based on the type and stage of cancer. Osteosarcoma often involves neoadjuvant chemotherapy followed by surgical resection, with adjuvant chemotherapy administered based on margin status. Ewing sarcoma primarily relies on multi-agent chemotherapy, with surgery or radiation considered based on response. Chondrosarcoma primarily involves surgical excision, with radiation used when surgery is not feasible.
