Knee Cancer Symptoms
One-sided knee pain is a significant knee cancer symptoms. The knee cancer is associated with bone tumor or cancer, so it is important to understand the bone cancer first and then the symptoms of knee cancer.
Bone cancer is the cancerous growth of tumor in the bone. The tumor destroys the normal bone tissue. In fact, not all bone tumors are cancerous. Benign tumors are more widespread than malignant tumors.
The cancerous tumors that form in the bone are called primary bone cancer. The breast, prostate, or lung cancers metastasize to the bones and are called metastatic cancer. Primary bone cancer is less common as compared to the metastatic cancer.
The knee cancer is the one of the three types of bone cancer that forms in various parts of the body. Bones are made of three tissues: fibrous, cartilaginous, and osteoid and in combination with the bone marrow. The knee cancer is the cancer that begins in knees. Osteosarcoma is the first type of primary bone cancer. Osteosarcoma is a tumor that mostly occurs in the knee and upper arm.
The other two types of primary bone cancer are the Ewing Sarcoma Family of Tumors (ESFTs) and chondrosarcomas that arise in soft tissue and pelvis, shoulder, and upper leg respectively.
Osteosarcoma is mostly diagnosed in people who are between 10 to 19 years of age. Paget disease occurs to the people who are over 40 years of age. These people are at increased risk of getting knee cancer.
Knee Cancer Symptoms
- Night pain-knee pain worsens at night
- Swelling-if the tumor grows then the person experiences swelling in the knee
- Weakness-the knee bones get weakened and may have fracture
- Exercise-the pain may grow after daily exercise, after walking for some time, or standing for prolonged time
A person having complaints regarding knee must ask the orthopedic about the test that will differentiate the pain. The diagnostic test will help the doctor to plan a treatment.
Various scanning tests are preferred to diagnose the disease. The most preferred is x-rays.
An x-ray gives a clear idea about the location, size, and shape of the bone tumor. If the x-ray is showing an abnormal area then the doctor may order for imaging tests.
A bone scan is a test in which a little amount of radioactive material in instilled into a blood vessel and travels through the bloodstream. The radioactive material is scanned for affected area.
A CT scan gives sequence of pictures of affected areas inside the body.
An MRI scan uses a magnet connected with a computer to generate pictures of the body.
A positron emission tomography (PET) scan checks the areas inside the body in which radioactive glucose is being injected through vein. The scanning image shows the cancer cells that absorbs the radioactive glucose.
An angiogram is an x-ray taken of blood vessels.
Alkaline phosphates which are enzymes present in the blood are checked via blood test. The amount of enzymes rises when the bone tissue becomes very active.
A biopsy is the surest way to determine the presence of the cancer cells. In this scenario, the surgeon performs an incisional or a needle biopsy. The test is the removal of a tissue sample from the bone tumor. The sample is sent to a laboratory where the pathologist observes it for cancer cells.
Surgery, chemotherapy, radiation therapy, and cryosurgery are the four treatments that a doctor will suggest to the patient based on the results of the diagnostic tests. Cryosurgery is different from remaining treatments.
Cryosurgery is the use of liquid nitrogen to solidify and destroy cancer cells. This technique is used instead of the traditional surgery to remove the tumor.
Participation in the clinical trial will definitely help the patient with knee cancer. The knee cancer symptoms have been explained thoroughly along with their diagnostic tests.
