Would it b possible to b diagnosed with melanoma on a path reprt but not yet know the staging?

Staging (Definition)

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

What is the definition or description of: pet-ct melanoma diagnosis?

What is the definition or description of: pet-ct melanoma diagnosis?

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 more

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.

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 more

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?

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 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?

Not necessarily: The decision to perform a sentinel node biopsy hinges on factors in the original melanoma biopsy and is not affected by "negative" x-rays or scans because only sentinel node biopsy can detect microscopic disease in lymph nodes. ...Read more

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?

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 more

Is melanoma common in 26 year old male?

Is melanoma common in 26 year old male?

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.

How does melanoma spread throughout the body?

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 more
