New Delhi: Bone cancer, although relatively uncommon, poses a significant challenge due to its often subtle and easily overlooked symptoms. Early detection is crucial for improving treatment outcomes and survival rates. Understanding the early signs and the diagnostic process can empower patients and healthcare providers to catch the disease in its nascent stages.
In an interaction with News9Live, Dr. Avinash Phadke, President & Mentor, Agilus Diagnostics Ltd, shared the importance of timely diagnosis for bone cancer patients.
Understanding Bone Cancer
Bone cancer can originate in any bone but commonly affects the long bones in the arms and legs. It primarily occurs in two forms: primary bone cancer, which starts in the bone, and secondary (or metastatic) bone cancer, which spreads from another part of the body. The most common types of primary bone cancer include osteosarcoma, chondrosarcoma, and Ewing sarcoma.
Osteosarcoma typically affects teenagers and young adults, often emerging during the growth spurts of adolescence. Chondrosarcoma generally occurs in middle-aged and older adults, originating in cartilage cells. Ewing sarcoma, though less common, primarily affects children and young adults, typically appearing in the bones of the pelvis, thigh, and upper arm.
Recognising Early Symptoms
Early symptoms of bone cancer can be vague and easily attributed to other, less serious conditions. Key signs to watch for include:
Persistent Pain: Unlike typical bone pain that subsides with rest, cancer-related bone pain tends to persist and worsen over time, especially at night. This pain is often misattributed to growth pains or injuries.
Swelling and Lumps: Swelling around the affected bone can occur, sometimes accompanied by a noticeable lump or mass. This swelling may not be evident until the tumor has grown significantly.
Fractures: Bones weakened by cancer are more susceptible to fractures or breaks from minor injuries or falls. These pathological fractures occur because the bone structure is compromised by the tumour.
Fatigue and Weight Loss: Unexplained fatigue and weight loss can also be indicative of an underlying malignancy. These systemic symptoms are often overlooked but can signal the body is fighting a serious illness.
Reduced Mobility: In cases where the cancer affects a joint, patients may experience stiffness, reduced mobility, or difficulty performing everyday activities.
Diagnostic Techniques
Early diagnosis of bone cancer involves a combination of imaging tests, biopsies, and laboratory tests. Key diagnostic methods include:
X-rays: Initial imaging to detect abnormalities in bone structure. X-rays can reveal changes in the bone that suggest the presence of a tumor.
MRI and CT Scans: Detailed imaging to assess the extent of the tumor and its impact on surrounding tissues. These scans provide a clearer picture of the tumor’s size, location, and whether it has invaded nearby structures.
Bone Scans: Radioactive tracers highlight abnormal bone activity, indicating potential cancer. This technique helps identify areas of bone metabolism that are unusual and may suggest malignancy.
Biopsy: A definitive diagnosis is made by extracting and examining a sample of the suspicious tissue. There are two main types of biopsy: needle biopsy, where a small sample is taken using a needle, and surgical biopsy, where a larger sample or the entire tumor is removed for analysis.
Blood Tests: While not definitive, certain markers in the blood can suggest the presence of cancer. Elevated levels of alkaline phosphatase or lactate dehydrogenase (LDH) can indicate bone activity related to tumor growth.
Advances in Detection
Technological advancements have significantly improved the early detection of bone cancer. Innovations in imaging techniques, such as PET scans, provide detailed insights into the metabolic activity of cancer cells. PET scans can detect even small tumors by highlighting areas of high glucose metabolism, which is typical in cancer cells.
Additionally, advancements in genomics and molecular biology enable the identification of genetic mutations associated with bone cancer, facilitating earlier and more accurate diagnoses. Liquid biopsies, which analyse cancer-related genetic material in the blood, offer a less invasive option for detecting cancer and monitoring its progression.
Treatment Options
The treatment for bone cancer often involves a combination of surgery, chemotherapy, and radiation therapy. The choice of treatment depends on the type, location, and stage of the cancer, as well as the patient’s overall health. Surgery aims to remove the tumor while preserving as much function as possible. Chemotherapy uses powerful drugs to kill cancer cells or stop their growth, and radiation therapy uses high-energy rays to target and destroy cancer cells. In recent years, targeted therapies and immunotherapies have shown promise in treating bone cancer.
Targeted therapies focus on specific molecules involved in cancer growth, while immunotherapies boost the body’s immune system to fight cancer. These treatments offer hope for improved outcomes and reduced side effects compared to traditional therapies.
The Importance of Awareness
Raising awareness about the early signs of bone cancer is vital. Patients experiencing persistent bone pain or unexplained symptoms should seek medical advice promptly. Early intervention not only improves treatment efficacy but also enhances the quality of life for those affected. Healthcare providers should maintain a high index of suspicion when evaluating patients with unexplained bone pain or swelling, especially in high-risk groups such as adolescents and young adults. Prompt referral to specialists and timely diagnostic testing can make a significant difference in patient outcomes.
Conclusion
Early diagnosis and detection of bone cancer are critical for successful treatment. By recognizing the subtle signs and utilising advanced diagnostic techniques, healthcare providers can improve outcomes for patients facing this challenging disease. Increased awareness and vigilance can lead to timely interventions, ultimately saving lives.
Bone cancer, though daunting, can be effectively managed with early detection and appropriate treatment. Understanding the signs and advancements in diagnostic methods are key steps toward combating this disease and improving survival rates.
