This study evaluates the effectiveness of applying Hypertonic Saline solution directly on the Melanomas in reducing their sizes and/or number.

Many previous studies have shown that Cancer cells are over-hydrated, and that Hyponatraemia exists in many cases of Cancer. The Cancer cell's viability depends on Angiogenesis and formation of blood vessels that carry water and nutrients to the rapidly-dividing Cancer cells. This study tests the hypothesis that reducing the water content of Melanoma could lead to increasing its tonicity and hence inhibiting its growth. This reduction of water content can be achieved using Osmotic Pressure differential via applying highly saline solution - made by Sodium Chloride crystals wet with water - directly on the Melanoma for a certain amount of time, thus leading to water withdrawal from Melanoma cells. While the surrounding healthy skin cells can sustain temporary dehydration, Melanoma cells could be negatively affected.

Inclusion Criteria:

• Patients with clinically-confirmed Melanoma (any location and any stage) who have poorly responded to at least one cycle of conventional and standard therapy (Chemotherapy, Radiation or Drug therapy).
• Age 5 to 80 years old
• Life expectancy of at least 1 year
• Can understand and read English
• Lives in USA.

Patient who do not meet the Inclusion Criteria but still wish to participate will be accepted as Observational participants, but their Melanoma measurements will be not be taken into account when analyzing the Study statistically.

Exclusion Criteria:

• Skin eczema and/or other skin conditions contraindicated to skin dehydration.
• Ulcers or open wounds close to Melanoma
• Any medical condition that might cause the patient to lose consciousness
• Participants who are not residents of USA.
