  2. Spinal tumor - Wikipedia

    en.wikipedia.org/wiki/Spinal_tumor

    Spinal cord compression is commonly found in patients with metastatic malignancy. [10] Back pain is a primary symptom of spinal cord compression in patients with known malignancy. [11] Back pain may prompt a bone scan to confirm or exclude spinal metastasis. Rapid identification and intervention of metastatic spinal cord compression is ...

  3. Bone metastasis - Wikipedia

    en.wikipedia.org/wiki/Bone_metastasis

    Bone metastasis, or osseous metastatic disease, is a category of cancer metastases that result from primary tumor invasions into bones. Bone-originating primary tumors such as osteosarcoma, chondrosarcoma, and Ewing sarcoma are rare; the most common bone tumor is a metastasis. [1] Bone metastases can be classified as osteolytic, osteoblastic ...

  4. Metastasis - Wikipedia

    en.wikipedia.org/wiki/Metastasis

    The tumor in the lung is then called metastatic breast cancer, not lung cancer. Metastasis is a key element in cancer staging systems such as the TNM staging system, where it represents the "M". In overall stage grouping, metastasis places a cancer in Stage IV. The possibilities of curative treatment are greatly reduced, or often entirely ...

  5. Malignant peripheral nerve sheath tumor - Wikipedia

    en.wikipedia.org/wiki/Malignant_peripheral_nerve...

    Metastasis occurs in about 39% of patients, most commonly to the lung. Features associated with poor prognosis include a large primary tumor (over 5 cm across), high grade disease, co-existent neurofibromatosis, and the presence of metastases. [5] It is a rare tumor type, with a relatively poor prognosis in children. [6]

  6. Invasion & Metastasis - Wikipedia

    en.wikipedia.org/wiki/Invasion_&_Metastasis

    Cancer cells, however, lose this ability; even though cells may become grossly abnormal, they do not undergo apoptosis. The cancer cells may do this by altering the mechanisms that detect the damage or abnormalities. This means that proper signaling cannot occur, thus apoptosis cannot activate.

  7. Spindle cell sarcoma - Wikipedia

    en.wikipedia.org/wiki/Spindle_cell_sarcoma

    Spindle cell sarcoma in muscle tissue. Spindle cell sarcoma is a type of connective tissue cancer.The tumors generally begin in layers of connective tissue, as found under the skin, between muscles, and surrounding organs, and will generally start as a small, inflamed lump, which grows in size.

  8. Cancer staging - Wikipedia

    en.wikipedia.org/wiki/Cancer_staging

    Cancer staging can be divided into a clinical stage and a pathologic stage. In the TNM (Tumor, Node, Metastasis) system, clinical stage and pathologic stage are denoted by a small "c" or "p" before the stage (e.g., cT3N1M0 or pT2N0). This staging system is used for most forms of cancer, except brain tumors and hematological malignancies.

  9. Prostate cancer - Wikipedia

    en.wikipedia.org/wiki/Prostate_cancer

    Metastases compress the spinal cord in up to 12% of those with metastatic prostate cancer causing pain, weakness, numbness, and paralysis. [70] [71] Inflammation in the spine can be treated with high-dose steroids, as well as surgery and radiotherapy to shrink spinal tumors and relieve pressure on the spinal cord. [70] [71]
