I have recently discovered about the term melanoma and had something similiar near my butt for quite long time now...i thought it was since birth but turns out i didnt had any birth mark..i followed the 5 steps ABCDE checks and i had initial 4 for them quite not sure about the Evolving part..reading more about it got to know that it affects the lymp nodes..my one armpit is quite bigger that the other i had a lump few months back but it disappeared....About my medical history...i was diagnosed with thyroid at 22 and had taken treatment for TB as well at the age for 18..Currently i am having shortness of breath, head ache, fatigue, weakness and some swelling above my collor bone.. please suggest
