Signs of bone cancer. Including knee pain and bone

Cancer is a rare serious disease, which begins in any bone in the body, but it most commonly affects the pelvis or long bones in the arms and legs, as it constitutes less than 1% of all types of cancer, and is divided into 3 types.

Bone cancer can start in any bone in the body, but it most commonly affects the pelvis or long bones in the arms and legs. Bone cancer is extremely uncommon, accounting for less than 1% of all cancers. In fact, noncancerous bone tumors appear more commonly than cancerous tumors.

Cancers that begin in other parts of the body and spread (metastasize) to the bones are not included in the phrase "bone cancer". Instead, these cancers are named after where they started, such as breast cancer that has metastasized to the bones.

Some types of bone cancer occur mainly in children, while others most often affect adults. Surgical removal is the most common treatment, but chemotherapy and radiation therapy can be used. The decision to use surgery or chemotherapy and radiation therapy depends on the type of bone cancer being treated.

There are signs that if they appear on parts of your body, they can warn you of the risk of developing a serious disease in the body, bone cancer.

Osteosarcoma:

It starts in the cells that make up the bone, most often occurs in long bones, more often in the legs, but sometimes in the arms, and also occurs in the soft tissues outside the bones.

Its symptoms include:

Swelling near the bone.

Bone or joint pain.

Bone injury or fracture for no known cause.

Knee pain.

Cartilage sarcoma:

A rare type of cancer that usually begins in the bones, but may sometimes occur in soft tissues near the bones, and occurs most often in the pelvis, hip and in certain uncommon cases, the shoulder region and the spine's bones may be affected.

Its symptoms include:

Increased pain.

Swelling in areas of the body.

Impaired bowel and bladder control.

Spinal cord problem.

Ewing's sarcoma:

A rare type of cancer occurs in the bones or in the soft tissues around the bones, often starting in the soft tissues of the chest or abdomen.

Symptoms:

Pain near the affected area.

Bone pain.

Idiopathic fatigue.

Fever of no known cause.

Lose weight without trying.

Symptoms of bone cancer in general:

Bone pain.

Swelling near the affected area.

Weakening of the bones, leading to fracture.

Exhaustion.

Unexplained weight loss.

Causes:

The cause of most bone cancers is unknown, and a few bone cancers have been attributed to genetic factors, while others are caused by previous radiation exposure.

Risk factors:

The causes of bone cancer are unclear, but doctors have found specific factors associated with a higher risk of developing it, including:

Inherited genetic syndromes. Certain rare and inherited genetic syndromes that are inherited in the family increase the risk of bone cancer, including Li-Frömeni syndrome and hereditary retinoblastoma.

Paget's disease affecting the bones. Paget's disease of the bones is more common in older adults and increases the risk of bone cancer later.

Radiation therapy for cancer. Exposure to high doses of radiation, such as those released when radiation therapy for cancer, increases the risk of future bone cancer.

When to see a doctor?

Make an appointment with your doctor if you or your child has bone pain with the following symptoms:

*Appears and goes away.

*Gets worse at night.

*Does not go away when using over-the-counter pain relievers.
