Melanoma is one of three types of skin cancer. While it is the rarer form, it is the most dangerous one to develop. It is so deadly because it has a higher chance of spreading to other parts of the body. However, you can prevent its spread with timely treatment, starting with your own skin checks and regular skin examinations at your dermatologist. These cancerous growths develop when melanocyte cells (the ones that make melanin) begin to grow out of control.
It may appear as a new mole, affect an existing mole, show up as a dark spot changing shape, present as distinct raised bumps that are brown, black, pink, or red, or emerge as abnormal tan or brown spots on sun-exposed areas.
Treatment for melanomas depends on how extensive the growth is. During a skin consultation, your dermatologist will conduct a thorough skin examination and x-rays to determine how deep the skin cancer has gone. Depending on the growth, your dermatologist will decide on one or a variety of methods to treat melanoma.
Mohs Micrographic Surgery involves the use of a microscope. Doctors cut away thin layers of cancerous skin and evaluate each layer under the microscope. They continue this process until all signs of the cancer are gone. They may use nitrogen to freeze it off by cryosurgery. Sometimes direct excision can remove it. Radiation treatment can kill cancer cells over several sessions. In some cases, topical creams can help.
Prevent melanoma by being careful with the sun. Wear SPF 30 and long-sleeved clothing. Wide-brimmed hats protect the face and neck areas. Avoid being outside in direct sun from 10 am to 2 pm, when UV rays are the strongest. Window tinting in cars and home windows can also block strong direct sun. Check your skin regularly for changes and see your dermatologist for annual skin screenings.
