Background: A ghost tumor (GhT) is a space-occupying lesion with radiologic features consistent with the diagnosis of tumor that on further investigation is revealed not to be a tumor, although definitions in the literature are inconsistent, and the incidence of GhT remains undefined.
Lymphomas involving Central Nervous System are well known to be steroid sensitive. Initial response rate of Central Nervous System lymphoma can be as high as 70 percent. Therefore, sometimes they are referred as 'ghost tumours'.
Silent cancers are cancers that do not have any noticeable early symptoms. Some silent cancers include breast cancer, ovarian cancer, colorectal cancer, Pancreatic cancer and lung cancer.
Cancerous tumors can come back after treatment (cancer recurrence). These tumors can be life-threatening. Noncancerous: Benign tumors are not cancerous and are rarely life-threatening. They're localized, which means they don't typically affect nearby tissue or spread to other parts of the body.
Non-glioma tumors are tumors that arise from cells in the brain that are not glial cells. Types of non-glioma tumors include: Meningioma. Meningioma is the most common primary brain tumor. It begins in the meninges and is most often noncancerous.
Atypical Teratoid Rhabdoid Tumor (ATRT) Diagnosis and Treatment. ATRTs are very rare, fast-growing tumors that often occur in the brain and spread to the spinal cord. They are caused by changes in a gene known as SMRCB1. Learn more about ATRTs.
Robert Lustig, M.D. to give us the rundown on the four most common brain tumors: metastatic, meningioma, glioblastoma, and astrocytoma.
Lung and bronchus cancer is responsible for the most deaths with 130,180 people expected to die from this disease. That is nearly three times the 52,580 deaths due to colorectal cancer, which is the second most common cause of cancer death. Pancreatic cancer is the third deadliest cancer, causing 49,830 deaths.
Benign bone tumors are non-cancerous and not typically life threatening. There are many types of benign bone tumors.
Imaging is used not only for local staging but also to differentiate between benign and malignant lesions. MRI is the preferred imaging modality for the evaluation of soft-tissue masses in clinical practice.
Some types of cancer do not form a tumor. These include leukemias, most types of lymphoma, and myeloma.
If you're wondering how long you can have cancer without knowing it, there's no straight answer. Some cancers can be present for months or years before they're detected. Some commonly undetected cancers are slow-growing conditions, which gives doctors a better chance at successful treatment.
Lymphoplasmacytic lymphoma or Waldenstrom macroglobulinemia.
This is a rare, slow-growing type of lymphoma. It's found mainly in the bone marrow, lymph nodes, and spleen. This type of lymphoma can't be cured. But people can live with it for many years.
The overall 5-year survival rate for people with NHL in the United States is 73%. For stage I NHL, the 5-year survival rate is more than 84%. For stage II the 5-year survival rate is 77%, and for stage III it is more than 71%. For stage IV NHL, the 5-year survival rate is almost 64%.
Tumours have been known to disappear spontaneously, in the absence of any targeted treatment, usually after an infection (bacterial, viral, fungal or even protozoal).
Cancer survival rates by cancer type
The cancers with the lowest five-year survival estimates are mesothelioma (7.2%), pancreatic cancer (7.3%) and brain cancer (12.8%). The highest five-year survival estimates are seen in patients with testicular cancer (97%), melanoma of skin (92.3%) and prostate cancer (88%).
Benign tumors are those that stay in their primary location without invading other sites of the body. They do not spread to local structures or to distant parts of the body. Benign tumors tend to grow slowly and have distinct borders.
Some cancers are difficult to treat and have high rates of recurrence. Glioblastoma, for example, recurs in nearly all patients, despite treatment. The rate of recurrence among patients with ovarian cancer is also high at 85%.
Aside from leukemia, most cancers cannot be detected in routine blood work, such as a CBC test. However, specific blood tests are designed to identify tumor markers, which are chemicals and proteins that may be found in the blood in higher quantities than normal when cancer is present.
Neurofibroma. Neurofibromas are benign, generally painless tumors that can grow on nerves anywhere in the body. In some cases, these soft, fleshy growths develop in the brain, on cranial nerves or on the spinal cord.
Glioblastoma, also known as glioblastoma multiforme, can be very difficult to treat and a cure is often not possible.
