### input:
So to begin with, I have major health issues specially cancer that curse the women in my family. My mother had ovarian cancer at 20 and another type at 25 that post menopausal women get, landed her in medical books. Anyway, so I m very cautious of my health especially since I ve had my daughter.. At 13 I had a large discolored mole removed from under my right shoulder blade, I don t remember further tests being done. I ve had several suspicious moles for years now (large, discolored, edgy borders, and growth to them). recently I ve noticed new large moles, I ve also been feeling unwell and fatigued for no reason. My right shoulder has been very achey, when I went to rub it I noticed a lump that hurt when I pressed on it.there was no markings in my skin that it was a pimple.but I tried popping it and it only bled. Now my shoulder hurts still it s a still pain that s moved down to my right elbow.whenever I push on it, it now sends a shooting tingly pain to my fingertips.I ve also noticed a dark line on my left index and middle finger nail. And yes I m concerned it s melanoma, that was my great nanas first cancer.

### output:

Hi, dairy have gone through your question. I can understand your concern. Symptoms of melanoma are increase in number of mole.  Change in color, texture and size of old moles.  You should go for biopsy of moles.  You may have simple nevus, compound nevus or malignant melanoma.  Biopsy will give you exact diagnosis.  If needed go for IOC marker study on biopsy.  Get the exact diagnosis and then take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
