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

Skin Cancer (Definition)

A condition in which some element of your skin--which is one of the most complex organs in the body--degenerates into cancer. The three most common types of skin cancer are: basal cell, squamous cell, and melanoma which occur in that order and degree of aggressiveness. Although heredity plays a major role, sun exposure and tobacco use and ...Read more

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.

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?

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.

I did a search for diagnosis of some of my symptoms and came up with melanoma. What do doctors look for to diagnose it?

I did a search for diagnosis of some of my symptoms and came up with melanoma. What do doctors look for to diagnose it?

Skin exam &biopsy: Melanoma is diagnosed by performing a complete skin exam and by taking a sample (biopsy) of the suspicous areas. The skin biopsy is then examined under a microscope to determine if it is melanoma. See the picture to find out what typical melanoma moles look like. Read more

If nodular melanoma was picked off. Would a biopsy of the underlying tissue a few months later still be accurate to make a diagnosis.

If nodular melanoma was picked off. Would a biopsy of the underlying tissue a few months later still be accurate to make a diagnosis.

Possibly: Depending on the depth the melanoma, a biopsy of the area could detect abnormal cells. Best to see a dermatologist as soon as possible. Read more

Picked off mole (maroon, black tissue initially mistook as blood blister)what I realized later looked exactly= Nodular melanoma. Would bx still be accurate for diagnosis since I picked off visible lesion.

Picked off mole (maroon, black tissue initially mistook as blood blister)what I realized later looked exactly= Nodular melanoma. Would bx still be accurate for diagnosis since I picked off visible lesion.

Biopsy needed: Yes, if this is in fact a melanoma, a biopsy would still show it even though you pulled off the top layer. If it's not a melanoma, a diagnosis could still possibly be made. It would be uncommon for you to be able to simply pull off a melanoma however. See your dermatologist to be sure. Read more

Can you tell me about melanoma?

Can you tell me about melanoma?

Skin malignancy: Malignant melanoma is a highly malignant skin tumor, that if not brought under control by early surgical removal will metastasize to almost every organ in the body. Most important factor for aggressiveness was first Clarks level measuring depth of penetration but later changed to Breslows classification for thickness. Lesion less than 1mm favorable, more than 2 mm. Not good. Read more

Can anybody tell me what melanomas?

Can anybody tell me what melanomas?

Type of skin cancer: Melanoma is a very dangerous form of skin cancer, caused by the pigment producing cells of the skin. The skin is not the only place that melanomas form, because melanocytes (the cells that go bad) occur in many areas of the body. Skin melanoma is on the increase, but our ability to catch it early is also improving. If you have a changing skin mole, get it examined! Read more
