Bone metastasis
Bone Metastasis
Bone metastasis (pronunciation: /boʊn mɛˈtæstəsɪs/) is a condition where cancer cells spread from the primary site to the bone.
Etymology
The term "metastasis" is derived from the Greek "metastasis" meaning "removal from one place to another". The prefix "meta-" means "change" and "stasis" means "standing still".
Definition
Bone metastasis is a type of secondary cancer that begins in another part of the body and spreads to the bone. It is different from primary bone cancer, which starts in the bone itself.
Symptoms
Symptoms of bone metastasis include bone pain, broken bones, urinary incontinence, bowel incontinence, and weakness in the legs.
Causes
Bone metastasis occurs when cancer cells break away from the primary tumor and enter the bloodstream or lymphatic system, which can carry them to the bone. The most common types of cancer that spread to the bone are breast, prostate, and lung cancer.
Diagnosis
Diagnosis of bone metastasis typically involves imaging tests such as X-rays, CT scans, MRI scans, PET scans, and bone scans. Blood tests and a biopsy may also be used.
Treatment
Treatment for bone metastasis aims to relieve symptoms and slow the growth of the cancer. It may include radiation therapy, chemotherapy, hormone therapy, surgery, pain medication, and bisphosphonates to help strengthen the bone.
