18 Feb How Dermatologists Approach Treatment for Melanoma
Melanoma is a skin cancer that forms in pigment cells. These cells are called melanocytes. Dermatologists look for melanoma through close skin examinations. Diagnosis depends on the cancer’s stage. The stage tells whether the cancer is only on the skin or has spread. Staging is key for treatment planning. Doctors often perform a physical exam. They may remove a skin sample, which is called a biopsy. They use this sample for laboratory testing. The cancer’s thickness and spread is checked through these tests. Treatment methods differ by stage. Some cases need only surgery. Others require more complex therapies. Early detection is associated with better results. The following sections describe each approach in simple terms.
Determining the Extent
The first step is to find out how far the melanoma has grown. A physical exam is done. The dermatologist removes a small piece of skin with a biopsy. This biopsy goes to a lab for tests. The thickness gets measured. Doctors check if the cancer has moved to the lymph nodes or other areas. This helps assign a stage. Melanoma is staged from 0 to 4. Higher numbers mean a more serious disease. If the stage is greater than 1, a team of specialists may be involved. Doctors use a dermascope. A dermascope has light and magnification. This tool helps dermatologists see patterns or color changes. Simple and compound sentences help explain these steps. Complex cases receive team-based reviews.
Removing Melanoma Surgically
Dermatologists often find melanoma early. Surgery is the main treatment at this stage. The procedure is called wide local excision. The surgeon uses a ruler to decide how much tissue to remove. Usually, the doctor removes cancerous skin and some surrounding healthy tissue. For thin melanoma, one centimeter of healthy skin is taken. For a thicker melanoma, about two centimeters are removed. Lymph node surgery can also be needed. This occurs when cancer may have spread. The surgeon removes some lymph nodes to check for cancer cells. In most cases, this step prevents further spread. Most people recover well after early surgery. Sentences are short to make the process clear.
Treating Advanced-Stage Melanoma
More advanced melanoma needs extra methods. Immunotherapy works by helping the body’s immune system attack cancer cells. It is mostly for advanced cases. Sometimes targeted therapy is used. Targeted therapy finds and attacks certain gene mutations inside cancer cells. Specific medications are given for this purpose. Radiation therapy may also be used if cancer has spread widely. Energy beams target the cancer in certain body parts. When surgery cannot remove all the cancer, radiation may provide relief. Some treatments occur before or after surgery. Doctors may use several treatments together. These options allow doctors to manage melanoma in more complex cases.
Find a Dermatologist
Dermatologists select treatments based on melanoma type and stage. Diagnosis involves physical exams and tissue testing. Surgery is typical for early melanomas. Advanced melanoma often needs immunotherapy, targeted therapy, or radiation. Sometimes treatments are combined. Patients undergo regular checkups for several years. These visits catch any signs of the cancer returning. The approach to melanoma care uses evidence at each step. Find a dermatologist in your area.
