Comprehensive Guide on Melanoma: Signs, Symptoms, Causes, and Treatments
Melanoma, a specific kind of skin cancer, is a cause for concern due to its potential to spread rapidly if not detected early. This article aims to provide a clear and concise overview of melanoma, its signs, staging, treatment, and prevention.
Melanoma begins in skin cells called melanocytes. Early signs and symptoms are changes to an existing mole or the development of a new, unusual growth on the skin. Clues that a mole might be melanoma are irregular shape, irregular border, multicolored or uneven coloring, larger than a quarter of an inch, changes in size, shape, color, or surface, itchiness, oozing, or bleeding.
Doctors use a variety of exams and tests to help diagnose melanoma, including physical examination, blood chemistry studies, and imaging tests such as ultrasound, CT scan, MRI, and PET scan. A skin biopsy is the only way to confirm melanoma.
Staging is a crucial part of melanoma diagnosis. Doctors stage melanoma as follows: Stage 0, Stage 1 (1A and 1B), Stage 2 (2A, 2B, and 2C), Stage 3, and Stage 4. The first part of staging involves finding out how thick the tumor is, which can involve measuring the melanoma under a microscope.
Treatment for early stages of melanoma, such as Stage 0 and Stage 1, involves surgical removal of the cancer along with a margin of healthy skin and a layer of tissue underneath the skin. For Stage 2 melanoma, a complete excision along with a lymph node biopsy (or elective lymph node removal) is considered standard treatment. In more advanced stages, treatment may also include immunotherapy, targeted therapy, radiation, chemotherapy, vaccine therapy, or palliative therapy.
In Stage 3 melanoma, cancer has spread away from the primary tumor or into nearby lymph nodes. Treatment may include excision, immunotherapy, targeted therapy, radiation, vaccine therapy, or palliative therapy. In stage 4 melanoma, cancer has spread to distant parts of the body.
It's important to note changes to moles or new growths and report them to your doctor right away. Regular skin checks can help detect melanoma early and improve the chances of successful treatment. Melanoma survival rates are generally high, with 94.1% overall survival rate in the United States.
Melanoma can appear anywhere on the skin, including areas that don't receive much sun. UV light exposure is a leading risk factor for melanoma. Other factors that may increase the risk include having many moles, a family history of melanoma, age, biological sex, a weakened immune system, previous history of skin cancer, and certain health conditions or treatments that affect the immune system.
Prevention measures include avoiding the midday sun, using sunscreen, covering up, minimizing unnecessary UV exposure, and following a healthy lifestyle. Clinical trials can also offer innovative therapies not yet approved for general use.
Prominent researchers in the field of melanoma include Dr. Axel Hauschild, known for contributions to melanoma treatment and research, especially in immunotherapy; Professor Paul Bröckelmann and the team of Prof. Skoetz at the University of Cologne, who focus on sex differences in immunotherapy effectiveness for melanoma; and experts like Dr. Dirk Schadendorf who work on familial melanoma genetics and new immunotherapies such as checkpoint inhibitors and Tebentafusp, a promising drug for metastatic uveal melanoma.
Regular skin checks, early detection, and timely treatment are key to managing melanoma. When it comes to your individual outlook, survival rates are only rough estimates. Your doctor can offer you a more individualized assessment based on factors such as age and general health.
