Pet Melanoma Initial Staging
Many diseases have specific treatments based on their severity. A disease can have certain criteria to determine their severity and applying this criteria to determine how advanced the disease state is called staging. Most commonly this is applied to cancer, and be determining how far the cancer has spread locally and/or to distant sites a stage of cancer can be ...Read more
Metastases: PET CT is often utilized to identify metastases from melanoma. Utilizes isotope F18 FDG for glucose metabolism of malignant lesions to identify them. Most malignant neoplasms have increased metabolic activity. CT portion compares anatomic lesion with area of increased uptake shown by PET. ...Read moreSee 2 more doctor answers

Pet scan 3-4mm, suv value of 1, no further evidence of disease, before surgery melanoma 0.8 mm negative sln, blood samples normal, no other signs
What would cause a pet scan to not detect malignant melanoma that was about the size of a chocolate easter egg? I also have type II diabetes.
Many Factors: No test is always right, pet/ct included. Every patient's tumor is unique, too. How a particular tumor will take up the primary pet/ct tracer, called f-18 fdg, is also not perfectly known. Some consistently fail to take up FDG that pet/ct is rarely used to image them, but this is not true for melanoma. Finally, smaller tumors are always harder to see, no matter which imaging technique is used. ...Read moreSee 1 more doctor answer
Diagnosed- malignant melanoma 5/2017 Diagnosed - treated for anal cancer 5/2016. Pet scan done in March '16. If MM has spread, wouldn't PET scan show?
PET scan is a good t: PET scan is a good test to detect metastatic cancer. In fact it is our best imaging test to catch metastases early. Yet it has some limitations in that it can not show microscopic tumors/ small # of cells in the body...it only shows tumors that are bigger than half a centimeter (>5 mm). That is why this test has to be repeated every 3 to 4 months when there is a risk for the tumor to come back. ...Read more
My husband has a melanoma on the right side of his stomach. Blood work, X-ray and pet scan are normal. Does that mean it is not nessery for a node biopsy?
My father has metastatic melanoma, 1 lymph node involvement. Pet scan and CT scan shows no other metastasis at this time. Does this mean he is cured?
Melanoma...: Melanoma is a very tricky disease and must be followed closely. It can metastasize to odd places. It is good news that only 1 lymph node is seen on pet/ct rather than many lymph nodes but one should note that micrometastases or very small lesions may be below the resolution of pet imaging. ...Read moreSee 1 more doctor answer
Males and Melanoma: The incidence is slightly lower in men (probably due to the fact that men don't sunbathe or use tanning beds as frequently as women), but the risk of death is higher for men than women. There appears to be a biological difference in men vs. Women in our ability to deal with this type of tumor.

Recurrent melanoma: Generally, melanomas are black in color but often are dis homogeneous in the amount of pigment. Occasionally, some recurring melanomas lose their ability to produce pigment and appear as flesh colored lesions. Your dermatologist of course is in the best position to answer your questions. ...Read moreSee 1 more doctor answer
Surgery: Surgery is the best treatment of melanoma. If the melanoma has spread so that surgery is not possible there are new chemotherapeutic medication that shows some promise. Cancer centers also have vaccines and there is a medication called interferon that may help. In some cases radiation therapy is used to reduce symptoms but it cannot sure melanoma. ...Read moreSee 2 more doctor answers
Via blood and lymph: Like other cancers, melanomas spread (metastasize) via 2 pathways. First, via the lymph system, where the tumor gets caught in lymph nodes. Sentinel node biopsy is helpful to determine lymph node involvement. Next, it can spread via the blood. That's how melanoma can go from your skin anywhere to the brain, lung, liver, etc. It's propensity to do this makes melanoma so dangerous. ...Read moreSee 2 more doctor answers
