Diagnosis & Treatment Skin Cancer
How is Skin Cancer Diagnosed?Diagnosis
If a mole has begun to look suspicious or you notice a change in your skin texture that could be an early sign of skin cancer, don’t wait—make an appointment with dermatologist to get to the bottom of your symptoms.
To rule out skin cancer your doctor will conduct a:
- Full body cancer screening – Your doctor will examine your skin closely to establish whether the changes in your skin could be cancer
- Skin biopsy – If the doctor feels the area needs further investigation, a biopsy will be performed. Your doctor will remove a small piece of the skin and send it to the laboratory for further testing. This biopsy can conclude whether you have skin cancer and, if so, which type of cancer it is.
How is Skin Cancer Treated?Treatment
Each type of skin cancer is treated differently. Some cancers require removal through surgery while others, such as basal cell carcinoma, may only require topical medication. Other treatment approaches may include:
- Freezing (cryotherapy) – An extremely cold liquid (liquid nitrogen) is sprayed on the area to remove some forms of basal cell carcinoma or squamous cell carcinoma in situ
- Excisional surgery – A skin cancer treatment where the doctor will use a scalpel to remove tumors, moles, cysts, skin cancer or other growths on the skin using local anesthesia. Some healthy skin tissue is also removed during this procedure.
- Mohs surgery – The most effective way to treat basal cell carcinoma and squamous cell carcinoma. This type of specialized surgery is available at NewYork-Presbyterian and has the highest cure rate.
- Curettage – A small instrument called a curette is used to scrape away cancerous and precancerous skin tissue
- Radiation – Combined with other therapies, radiation is used to eliminate aggressive cancer cells or recurrent skin cancer
- Immunotherapy – Uses medicine to support a person's immune system to recognize and eliminate cancer cells more effectively
- Targeted therapy – Uses medicine to interrupt the cancer cell division by targeting the molecules that allow the cancer cells to spread
- Photodynamic therapy (PDT) – Uses a drug that is activated by laser light to kill cancer cells
- Biological therapy – Also called immunotherapy, biological therapy uses the body's own immune system to fight cancer cells
