Overview
Bone Cancer occurs when the cells within the bone begin to divide uncontrollably. It can affect any bone in the body, but it is most commonly found in the knee bone, thigh bone, pelvis, and other long bones in the arms and legs.
The cancer can be either primary—arising within the cells of the bone itself—or secondary—spreading to the bone from elsewhere in the body. While surgery remains the most common treatment, chemotherapy and radiation therapy are also widely used.
Causes of Bone Cancer
Doctors and researchers are not certain about the precise reason behind bone cancer. The causes may differ from person to person. In some cases, inherited DNA mutations or genetic conditions can increase the risk of developing bone cancer.
Symptoms of Bone Cancer
Symptoms may vary depending on the size and location of the tumour, but common signs include:
- Bone pain
- Swelling
- Weakened bone
- Weight loss and fatigue
- Problems in movement
- Fractures
- Numbness and tingling sensation
Prevention of Bone Cancer
While not all cases of bone cancer can be prevented, adopting healthy lifestyle practices can help reduce risk and support early detection:
- Know your family history
- Be informed about your bone health
- Eat a nutritious diet
- Exercise regularly
- Avoid tobacco
- Have an early diagnosis
Diagnosis of Bone Cancer
To accurately diagnose bone cancer, doctors perform a series of tests and evaluations to determine the location, size, and nature of the tumour:
- Imaging Tests: CT scans, MRIs, PET scans, and X-rays help visualize the tumour’s size and spread.
- Biopsy: A tissue sample is taken from the tumour to examine it under a microscope and confirm if it is cancerous, as well as determine its type.
Treatment Options for Bone Cancer
Surgery
The main goal of surgery is to remove the entire tumour along with a small portion of healthy tissue around it. In rare and complex cases, part of a limb may need to be removed. However, with advancements in treatment, limb-sparing surgeries are becoming more common.
Chemotherapy
Uses anti-cancer drugs, usually delivered intravenously, to destroy or stop the growth of cancer cells. Often used in combination with surgery or radiation.
Radiation Therapy
Involves the use of high-energy beams to destroy cancer cells, shrink tumours, and reduce symptoms. It also helps make tumours easier to remove surgically.
Targeted Therapy
This treatment uses specialized drugs designed to attack specific molecules that help cancer grow and spread. It is less damaging to healthy cells compared to traditional chemotherapy.
Takeaway
Bone cancer, though rare, can be effectively treated when detected early. Maintaining strong bone health and seeking medical advice for unexplained pain or swelling can lead to timely intervention.
Awareness, early diagnosis, and proper treatment improve both recovery chances and quality of life.
