Top 4 Upper Leg Bump Causes

  1. 1.Cancer of Fat Cells

    Liposarcoma is a type of cancer characterized by tumors growing in fatty tissues. This cancer can occur in any part of the body, but most often involves the thigh or the belly (abdomen).

    You should visit your primary care physician who will coordinate your care. The treatment for liposarcoma involves surgery to take out the tumors, as well as radiation therapy.

  2. 2.Benign Bony Growth (Osteochondroma)

    An osteochondroma is a non-cancerous growth that usually develops during childhood or adolescence. It is a benign tumor that forms on the surface of a bone near the growth plate.

    You should visit your primary care physician for X-Ray evaluation. In most cases this condition is treated by careful observation over time to make sure the tumor does not grow. Surgery is considered if the osteochondroma causes pain, puts pressure on a nearby nerve or blood vessel, or has a large cap of cartilage.

  3. 3.Osteogenic Sarcoma

    Osteogenic sarcoma (osteosarcoma) is a cancer that starts in the bone, and usually affects the ends of the bone where new tissue forms at a growth plate. It is the most common cancerous bone tumor in young people, with the average age at diagnosis being 15 years. Pain in the bone is the most commonly reported symptom.

    You should visit your primary care physician who will be able to coordinate your care with a cancer specialist (oncologist). This condition is treated with chemotherapy and surgery. Unfortunately, surgery may involve amputation of the entire limb.

    Rarity:
    Rare
    Top Symptoms:
    spontaneous bone pain, swollen shin, lower leg bump, upper leg bump
    Symptoms that always occur with osteogenic sarcoma:
    spontaneous bone pain
    Urgency:
    Primary care doctor
  4. 4.Fibrous Dysplasia of Bone

    This is a genetic condition where part of a bone develops incorrectly using the wrong type of materials (fibrous instead of bony tissue), causing a weak area of bone that is prone to fractures. This process begins before birth, and the cause of the gene mutation is not fully known.

    You should visit your primary care physician who will confirm the diagnosis with X-Ray. Surgical treatment is often necessary to stabilize the bone.

    Rarity:
    Rare
    Top Symptoms:
    spontaneous hip pain, spontaneous bone pain, pain in one thigh, lump below the skin on the chest
    Symptoms that always occur with fibrous dysplasia of bone:
