How do you treat a malignant melanoma on bottom of foot?

Same treatment. Treatment will be dictated by the same features as any melanoma: physical exam for possible metastatic disease, tumor thickness, ulceration, and mitotic rate. Thus the treatment will likely include wide excision and possibly sentinel node biopsy . The main difference for this location is that reconstruction of the primary site could require skin graft or a flap.
Removal. With wide excision (removal with an appropriate amount of normal skin around it) and possibly sentinel node biopsy. The width of the excision varies depending on the thickness of the melanoma as does the need for node biopsy. Depending on the location, you may be able to have the wound closed with stitches (not common), have a skin graft (more common), or have a complex plastic surgical repair.
BIOPSY TO CORFIRM. If positive, excision. Check lymph nodes.
Surgery. Surgery is the mainstay in the treatment of melanoma. The melanoma needs to be excised with a margin of normal skin around it. And depending on the characteristics o the melanoma a sentinel lymph node procedure may need to be performed.

How long can you live if your malignant melanoma is treated before it spreads?

Cure is possible. Depending on size and volumn a small lesion that has not ulcerated, if less than 1 mm. thick and is free of any satellites adjacent to the primary can be cured. If there are local satellites, Ive seen cures with intralesional BCG. If at high risk, chemo infusion into an extremity can reduce recurrence and with alpha interferon, IL-2 and new checkpoint inhibitors many cures noted. 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...
