Hi. Greetings. Yes this is a sign of cancer of the melanocytes in the nail bed. BUT NOT IN INDIANS! I GUESS YOU HAVE BEEN MISGUIDED BY GOOGLE. This problem is common in Indians and dark races and not related to cancer in us. However, if you are really scared you must visit a dermatologist and discuss the same with him.. Nail biopsy usually costs up to 1 to 3 k depending on the city and place you get it done. However not needed in your case is what I would opine. Relax. Hope this helps.
