Mikhail Myasnyankin notes that malignant formations are actually subungual. Their main marker is stripes of different colors in the area of the nail bed: from brown to black. They can be either single or take up the entire space. The doctor also advises to monitor the appearance of cracks or brittle nails, as well as bruises; if they are found, one needs to contact a specialist. If the treatment of a fungus or an infectious lesion of the nail plate for a long time has not led to results, then one should also visit a doctor.
The oncologist made a point of shellac popularity noting that its application together with the use of ultraviolet lamps can affect existing formations on the nail bed and lead to cancer. Therefore, Myasnyankin suggested giving up this type of coating and replacing it with those that do not require ultraviolet light for their use.
All of the above markers, as the doctor emphasizes, relate to melanoma, the insidiousness of which lies in the fact that the tumor is not always pigmented. Besides, he did not rule out the possibility of skin cancer, skin soft tissue sarcoma, and squamous cell carcinoma. However, Myasnyankin notes that changes in the nail bed may not always be malignant: there are many benign formations.
