Medical Treatment For Skin Cancer
Surgical removal is the mainstay of skin cancer treatment for both basal cell and squamous cell carcinomas. For more information, see Surgery.People who cannot undergo surgery may be treated by external radiation therapy. Radiation therapy is the use of a small beam of radiation targeted at the skin lesion. The radiation kills the abnormal cells and destroys the lesion. Radiation therapy can cause irritation or burning of the surrounding normal skin. It can also cause fatigue. These side effects are temporary. In addition, topical chemotherapy creams have been FDA approved for the treatment of certain low-risk nonmelanoma skin cancers. Patients with advanced or many basal cell carcinomas are sometimes prescribed oral pills to block the growth of these cancers. Side effects include muscle spasms, hair loss, taste changes, weight loss and fatigue.
In advanced cases of melanoma, immune therapies, vaccines, or chemotherapy may be used. These treatments are typically offered as clinical trials. Clinical trials are studies of new therapies to see if they can be tolerated and work better than existing therapies.
Surgery For Skin Cancer
Small skin cancer lesions may be removed through a variety of techniques, including simple excision , electrodesiccation and curettage , and cryosurgery .
Larger tumors, lesions in high-risk locations, recurrent tumors, and lesions in cosmetically sensitive areas are removed by a technique called Mohs micrographic surgery. For this technique, the surgeon carefully removes tissue, layer by layer, until cancer-free tissue is reached.
Malignant melanoma is treated more aggressively than just surgical removal. To ensure the complete removal of this dangerous malignancy, 1-2 cm of normal-appearing skin surrounding the tumor is also removed. Depending on the thickness of the melanoma, neighboring lymph nodes may also be removed and tested for cancer. The sentinel lymph node biopsy method uses a mildly radioactive substance to identify which lymph nodes are most likely to be affected.
What Is A Melanocyte
Melanocytes are skin cells found in the upper layer of skin. They produce a pigment known as melanin, which gives skin its color. There are two types of melanin: eumelanin and pheomelanin. When skin is exposed to ultraviolet radiation from the sun or tanning beds, it causes skin damage that triggers the melanocytes to produce more melanin, but only the eumelanin pigment attempts to protect the skin by causing the skin to darken or tan. Melanoma occurs when DNA damage from burning or tanning due to UV radiation triggers changes in the melanocytes, resulting in uncontrolled cellular growth.
Naturally darker-skinned people have more eumelanin and naturally fair-skinned people have more pheomelanin. While eumelanin has the ability to protect the skin from sun damage, pheomelanin does not. Thats why people with darker skin are at lower risk for developing melanoma than fair-skinned people who, due to lack of eumelanin, are more susceptible to sun damage, burning and skin cancer.

Why Does It Happen
Non-melanoma skin cancer is mainly caused by overexposure to ultraviolet light. UV light comes from the sun, as well as artificial sunbeds and sunlamps.
In addition to UV light overexposure, there are certain things that can increase your chances of developing non-melanoma skin cancer, such as:
- a family history of the condition
- pale skin that burns easily
- a large number of moles or freckles

Benign Tumors That Develop From Other Types Of Skin Cells
- Seborrheic keratoses: tan, brown, or black raised spots with a waxy texture
- Hemangiomas: benign blood vessel growths, often called strawberry spots
- Lipomas: soft growths made up of fat cells
- Warts: rough-surfaced growths caused by some types of human papilloma virus
Most of these tumors rarely, if ever, turn into cancers. There are many other kinds of benign skin tumors, but most are not very common.

Skin Cancer Of The Head And Neck Treatment
Many early-stage small basal cell cancers or squamous cell cancers can be removed by Mohs surgery, a technique that spares normal tissue through repeated intraoperative margin testing, removing only the cancer and leaving adjacent normal tissue. Tumors with nerve involvement, lymph node involvement or of a large size are not suitable for Mohs surgery. They require a multimodality approach to treatment, with formal surgical resection and adjuvant radiation or chemotherapy.
Melanoma is more likely to spread, and aggressive surgical resection with wide margins is required, in addition to radiation and/or chemotherapy.

How Can You Manage Stage 3 Melanoma
Managing stage 3 melanoma can be challenging. With technological and medical advances, this diagnosis may not be as severe as it once was.
After your surgery or if youre unable to undergo surgery, you may need adjuvant treatment to prevent the cancer from coming back. There is adjuvant radiation therapy and adjuvant immunotherapy. These therapies help reduce the risk of melanoma returning, but they dont increase your survival rate.
Where To Find Support For Stage 3 Melanoma
With a melanoma diagnosis, its important to reach out to those close to you during your treatment. In addition to family and friends, there are many support groups and resources who can help answer questions or provide a listening ear.
Find a melanoma support group. The American Melanoma Foundation maintains a list of support groups throughout the country find them by .
Join an online support group. If you feel more comfortable participating in an online support group, the AIM at Melanoma Foundation offers a support community as well as counseling.
Seek financial assistance, if needed. The Melanoma Research Foundation has developed a central resource for patient assistance programs and government entities that offer financial assistance for those with melanoma. For more information, please .
Sign up for a mentoring program. Olympic figure skater Scott Hamiltons charity, 4th Angel, offers a mentoring program for those with cancer. This telephone-based program is designed to provide support and encouragement to those with cancer.
Many organizations provide professional and supportive services when youve been diagnosed with melanoma. Other organizations that provide support for those with skin cancer include the:

What Are The Survival Rates For Metastatic Melanoma
Survival rates for melanoma, especially for metastatic melanoma, vary widely according to many factors, including the patient’s age, overall health, location of the tumor, particular findings on the examination of the biopsy, and of course the depth and stage of the tumor. Survival statistics are generally based on 5-year survival rates rather than raw cure rates. Much of the success reported for the targeted therapies focuses on disease-free time because in many cases the actual 5-year survival is not affected. It is hoped that combination therapy discussed above will change that.
- For stage 1 , 5-year survival is â¥ 90%.
- For stage 2 , 5-year survival is 80%-90%.
- For stage 3 , 5-year survival is around 50%.
- For stage 4 , 5-year survival is 10%-25% depending upon sex and other demographic factors.
What Are The Treatment Options For Melanoma
Surgery performed to remove the melanoma while leaving as much nearby skin intact as possible. The surgeon may also remove one or more nearby lymph nodes to look for signs that the cancer has spread.
Targeted therapy uses drugs directed at specific abnormal proteins in cancer cells. Patients whose melanoma carries a mutation in the BRAF gene may be treated with drugs that target the altered BRAF protein or the associated MEK proteins. Three drug combinations have been FDA-approved for metastatic and high-risk melanoma with a BRAF mutation: dabrafenib and trametinib encorafenib and binimetinib and vemurafenib and cobimetinib
Immunotherapy uses the bodys immune system to fight cancer cells. Dana-Farber scientists have led clinical trials of the drug ipilimumab, one of a class of immunotherapy drugs that are helping some patients with advanced melanoma survive 10 years or longer. In other Dana-Farber-led trials, the immunotherapy agent nivolumab achieved three-year survival rates of more than 40% in patients with metastatic melanoma. Dana-Farber investigators have also found that initially treating advanced melanoma patients a combination of nivolumab and ipilimumab results in a much higher response rate than treatment with ipilimumab alone. A range of other clinical trials testing various immunotherapies is also under way for patients with advanced melanoma.
Skin Conditions That Increase Skin Cancer Risk
Moles and Other Dark Blemishes
Certain moles and dark blemishes increase the risk for skin cancer. Any mole or other skin growth that seems new, changing, or unusual in any way should be evaluated by a health care professional. An existing mole can mutate and become cancerous. Although 80% of melanoma cases develop from brand new lesions or moles, your risk of developing the condition increases if you have the tendency to develop moles.
Some specific moles or dark blemishes that are risk factors for melanoma include:
The more moles a person has, the higher the risk that one of those moles will become cancerous, although the danger is still very small. The risk is higher with atypical moles.
Some skin growths can look like — but are not — melanoma. Noncancerous moles typically have the following characteristics:
- They generally remain small with clearly defined, regular borders, and uniform color. Some have a regular spotted or net-like pattern of pigmentation, however, and may even resemble early melanoma.
- They typically first appear during childhood, puberty, or young adulthood. They may naturally grow, darken, or increase in number at certain times of life, such as adolescence or pregnancy.
Examples of moles or growths that may resemble skin cancer include:
Spindle Cell Nevus
What Is Melanoma Skin Cancer
Melanoma is a type of skin cancer that develops when melanocytes start to grow out of control.
Cancer starts when cells in the body begin to grow out of control. Cells in nearly any part of the body can become cancer, and can then spread to other areas of the body. To learn more about cancer and how it starts and spreads, see What Is Cancer?
Melanoma is much less common than some other types of skin cancers. But melanoma is more dangerous because its much more likely to spread to other parts of the body if not caught and treated early.

When To Seek Medical Care For Skin Cancer
Many people, especially those who have fair coloring or have had extensive sun exposure, periodically check their entire body for suspicious moles and lesions.
Have your primary health care provider or a dermatologist check any moles or spots that concern you.
See your health care provider to check your skin if you notice any changes in the size, shape, color, or texture of pigmented areas .
If you have skin cancer, your skin specialist or cancer specialist will talk to you about symptoms of metastatic disease that might require care in a hospital.
Skin Exam And Physical
If youve been diagnosed with melanoma, youve already had a skin biopsy. This biopsy was taken when you had part of the suspicious spot removed. After it was removed, a doctor looked at the spot under a microscope to find out if it contained cancer cells. This is currently the only way to tell if someone has skin cancer.
After getting the diagnosis, the next step is to get a complete skin exam and physical.
During the physical, your dermatologist will feel your lymph nodes. This is where melanoma usually goes when it begins to spread. It usually travels to the lymph nodes closest to the melanoma.
If there is a risk the cancer could have spread, your dermatologist may recommend that you have a lymph node biopsy. If a sentinel lymph node biopsy is recommended, it can be performed at the time of your surgery for melanoma.
After the skin exam and physical, your dermatologist may recommend testing, such as a CAT scan, MRI, or a blood test. These can also help detect spread.

Guidelines For Avoiding The Sun And Uv Radiation
The following are some specific guidelines for avoiding excessive sun exposure:
- Properly use sunscreens that block out both UVA and UVB radiation with at least SPF 30. DO NOT rely on sunscreen alone for sun protection. Also wear protective clothing and sunglasses.
- Avoid sun exposure, particularly during the hours of 10 a.m. to 4 p.m., when UV rays are the strongest.
- Use precautions, even on cloudy days. Clouds and haze do not protect you from the sun, and in some cases may intensify UVB rays.
- Avoid reflective surfaces such as water, sand, concrete, and white-painted areas.
- UV intensity depends on the angle of the sun, not heat or brightness. The dangers are greater closer to the start of summer.
- Skin burns up to 4 times faster at higher altitudes than at sea level.
- Avoid sun lamps, tanning beds, and tanning salons. The machines use mostly high-output UVA rays.
How Dangerous Is Melanoma
Melanoma is usually curable when detected and treated early. Once melanoma has spread deeper into the skin or other parts of the body, it becomes more difficult to treat and can be deadly.
- The estimated five-year survival rate for U.S. patients whose melanoma is detected early is about 99 percent.
- An estimated 7,180 people will die of melanoma in the U.S. in 2021.

Exams And Tests For Skin Cancer
If you think a mole or other skin lesion has turned into skin cancer, your primary care provider will probably refer you to a dermatologist. The dermatologist will examine any moles in question and, in many cases, the entire skin surface. Any lesions that are difficult to identify, or are thought to be skin cancer, may then be checked. Tests for skin cancer may include:
- The doctor may use a handheld device called a dermatoscope to scan the lesion. Another handheld device, MelaFind, scans the lesion then a computer program evaluates images of the lesion to indicate if it’s cancerous.
- A sample of skin will be taken so that the suspicious area of skin can be examined under a microscope.
- A biopsy is done in the dermatologist’s office.
If a biopsy shows that you have malignant melanoma, you may undergo further testing to determine the extent of spread of the disease, if any. This may involve blood tests, a chest X-ray, and other tests as needed. This is only needed if the melanoma is of a certain size.
After Skin Cancer Treatment
Most skin cancer is cured surgically in the dermatologist’s office. Of skin cancers that do recur, most do so within three years. Therefore, follow up with your dermatologist as recommended. Make an appointment immediately if you suspect a problem.
If you have advanced malignant melanoma, your oncologist may want to see you every few months. These visits may include total body skin exams, regional lymph node checks, and periodic chest X-rays and body scans. Over time, the intervals between follow-up appointments will increase. Eventually these checks may be done only once a year.

When Melanoma Can’t Be Cured
If your cancer has spread and it is not possible to cure it by surgery, your doctor may still recommend treatment. In this case, treatment may help to relieve symptoms, might make you feel better and may allow you to live longer.Whether or not you choose to have anti-cancer treatment, symptoms can still be controlled. For example, if you have pain, there are effective treatments for this. General practitioners, specialists and palliative care teams in hospitals all play important roles in helping people with cancer.
Stages Of Melanoma Skin Cancer
Staging describes or classifies a cancer based on how much cancer there is in the body and where it is when first diagnosed. This is often called the extent of cancer. Information from tests is used to find out the size of the tumour, which parts of the skin have cancer, whether the cancer has spread from where it first started and where the cancer has spread. Your healthcare team uses the stage to plan treatment and estimate the outcome .
The most common staging system for melanoma skin cancer is the TNM system. For melanoma skin cancer there are 5 stages stage 0 followed by stages 1 to 4. Often the stages 1 to 4 are written as the Roman numerals I, II, III and IV. Generally, the higher the stage number, the more the cancer has spread. Talk to your doctor if you have questions about staging.
When describing the stage, doctors often use the words early stage, locoregional or metastatic.
Early stage means that the cancer is only in where it started and has not spread to other parts of the body. It includes stage 0, stage 1A, stage 1B, stage 2A, stage 2B and stage 2C melanoma skin cancers.
Locoregional means the cancer has spread to nearby lymph nodes, or it has spread to nearby areas of skin or lymph vessels. It includes stage 3 melanoma skin cancer.
Metastatic means that the cancer is in a part of the body farther from where it started. It includes stage 4 melanoma skin cancer.
