How Fast Does Skin Cancer Grow
Skin cancer starts when cells in the skin grow out of control. Some forms of skin cancer tend to grow in a matter of weeks, while others grow over months or longer. While a number of factors determine how fast or slow skin cancer may grow in any one individual, some types of skin cancer are more aggressive than others. In the space below, we look at typical growth rates for some specific types of cancer.
Most Melanoma Does Not Start In A Preexisting Mole
Melanoma can develop in a preexisting mole, says Dr. Marghoob, but nearly 70% of skin melanomas do not. Rather, they occur in normal skin. Moles themselves are not cancerous, and it is extremely rare for a mole to transform into a melanoma, says Dr. Marghoob. That said, he adds, having many moles helps identify people who are at an increased risk for developing melanoma somewhere on their skin.
Since most melanoma develops on normal skin, Dr. Marghoob stresses the importance of protecting the entire surface of the body, including areas with many moles and areas without any moles. Some people use sunblock only where they have moles because they think the moles themselves are dangerous, adds Dr. Marghoob. Stay safe by applying broad-spectrum sunblock with an SPF of at least 30, wearing sun-protective clothing, or using a combination of the two approaches.
Different Kinds Of Skin Cancer
There are many types of skin cancer. Some are very rare. Your doctor can tell you more about the type you have.
The two most common kinds of skin cancers are:
- Basal cell cancer, which starts in the lowest layer of the skin
- Squamous cell cancer, which starts in the top layer of the skin
Another kind of skin cancer is called melanoma. These cancers start from the color-making cells of the skin . You can read about melanoma in If You Have Melanoma Skin Cancer.

How Fast Breast Cancer Grows
One main reason for why people ask about how fast breast cancer grows, or its doubling time, is when they consider how long to wait to begin treatment. This growth rate also is important to understand if you have a lump and have been advised to simply observe it over time.
In general, the growth of breast cancer can be quite variable, but several studies provide at least an estimate of what may be happening.
Unless your healthcare provider is extremely confident that a lump is benign, it should be evaluated right away rather than waiting.
What Are The Symptoms Of Skin Cancer
The most common warning sign of skin cancer is a change on the skin, typically a new mole or skin lesion or a change in an existing mole.
- Basal cell carcinoma may appear as a small, smooth, pearly or waxy bump on the face, ears or neck, or as a flat pink, red or brown lesion on the trunk or arms and legs.
- Squamous cell carcinoma can appear as a firm, red nodule, or as a rough, scaly flat lesion that may bleed and become crusty. Both basal cell and squamous cell cancers mainly occur on areas of the skin frequently exposed to the sun, but can occur anywhere.
- Melanoma usually appears as a pigmented patch or bump but can also be red or white. It may resemble a normal mole, but usually has a more irregular appearance.
When looking for melanoma, think of the ABCDE rule that tells you the signs to watch for:
- Asymmetry — the shape of one half doesn’t match the other
- Border — edges are ragged or blurred
- Color — uneven shades of brown, black, tan, red, white or blue
- Diameter — A significant change in size , although any mole that is getting larger should be brought to the attention of your dermatologist many melanomas are being diagnosed at much smaller diameters.
- Evolving — any new spot or mole that is changing in color, shape or size or itches or bleeds.

Stem Cell Or Bone Marrow Transplant
A stem cell transplant, sometimes called bone marrow transplant, replaces damaged blood-forming cells with healthy ones. The procedure takes place following large-dose chemotherapy or radiation therapy to kill cancer cells and to stop your stem cells from producing cancerous cells.
Stem cell transplants can be used for several types of cancer, including multiple myeloma and some kinds of leukemia.
Key Points About Skin Cancer In Children
Skin cancer is rare in children.
Skin cancer is more common in people with light skin, light-colored eyes, and blond or red hair.
Follow the ABCDE rule to tell the difference between a normal mole and melanoma.
Biopsy is used to diagnose skin cancer.
Skin cancer can be treated with surgery, medicine, and radiation.
Staying out of the sun is the best way to prevent skin cancer.

What Changes In The Skin Occur Due To Exposure To The Sun
Exposure to sun causes most of the wrinkles and age spots on our faces. People think a glowing complexion means good health, but skin color obtained from being in the sun can actually speed up the effects of aging and increase the risk of developing skin cancer.
Sun exposure causes most of the skin changes that we think of as a normal part of aging. Over time, the sun’s ultraviolet light damages the fibers in the skin called elastin. When these fibers break down, the skin begins to sag, stretch, and lose its ability to go back into place after stretching. The skin also bruises and tears more easily in addition to taking longer to heal. So while sun damage to the skin may not be apparent when you’re young, it will definitely show later in life. The sun can also cause issues for your eyes, eyelids, and the skin around the eyes.
Changes in the skin related to sun exposure:
- Precancerous and cancerous skin lesions caused by loss of the skin’s immune function.
- Benign tumors.
- Fine and coarse wrinkles.
- Freckles discolored areas of the skin, called mottled pigmentation and sallowness, yellow discoloration of the skin.
- Telangiectasias, the dilation of small blood vessels under the skin.
- Elastosis, the destruction of the elastic tissue causing lines and wrinkles.
How Fast Does Squamous Cell Carcinoma Spread
Squamous cell carcinoma rarely metastasizes , and when spreading does occur, it typically happens slowly. Indeed, most squamous cell carcinoma cases are diagnosed before the cancer has progressed beyond the upper layer of skin. There are various types of squamous cell carcinoma and some tend to spread more quickly than others.

My wife of 40 years died very, very suddenly from pancreaticcancer in Feb 2012. She was a very fit and active woman she was on occasion doing some slightly ‘strange’things. Dutch by birth she sometimes reverted to speaking Dutch forno reason at all, and seemed at times to have a ‘split’ personality. I feel the pancreatic cancer was affectingher brain gradually over years……….. eventually it killed hervery quickly shutting down the brain completely. So sad. Miss herso much.
How Fast Does Melanoma Spread And What Should I Know About This Skin Cancer
Melanoma is the most lethal and serious type of skin cancer, with the exception of certain rare skin cancers, due to melanoma being often likely to metastasize to the internal organs and lymph nodes. 77 percent of all skin cancer-related deaths are due to melanoma, according to the American Academy of Dermatology. Being able to recognize this cancer when it is in its very early stages is crucial in surviving this skin cancer.

Treatment For Skin Cancer
If you are diagnosed with skin cancer, you may have multiple options for treatment. Based on the specifics of your case, your doctor will recommend your best course of action. The suggested methods for fighting the cancer may include:
Cryotherapy. In cryotherapy, a doctor freezes and kills precancerous or cancerous skin cells using liquid nitrogen. This technique is most often used to treat minor basal or squamous carcinomas or precancerous skin conditions.
Surgery. Different types of skin cancer may be removed by surgery. Surgery can be excisional – simply cutting out a cancerous area and the skin surrounding it – or may involve meticulous removal of layers of skin.
Radiation therapy. In radiation therapy, energy beams are used to kill cancerous cells. Radiation therapy may help finish off a cancer that was not fully removed by surgery, and can also be instrumental in cases that dont allow for surgery.
Chemotherapy. This type of therapy uses drugs to kill cancer cells. To treat some cases of skin cancer, chemotherapy may be applied locally through topical creams or lotions. It may also be administered by IV to target multiple body parts at once.
Immunotherapy. Immunotherapy, also called biological therapy, involves boosting the immune system to fight cancer cells. With the help of strengthening medicines, the immune system may be better prepared to kill cancerous cells.
How Long Does It Take To Recover From A Chemical Peel
Peeling skin before it is ready to come off can be counter-productive. After three to four days, most of the peeling should be complete, but it may take anywhere from five to seven days before your fresh, new skin has developed. Within seven to fourteen days, your skin should be completely healed. If you work in an office or indoor setting, you …

Causes Of Skin Cancer
Both types of skin cancer occur when mutations develop in the DNA of your skin cells. These mutations cause skin cells to grow uncontrollably and form a mass of cancer cells.
Basal cell skin cancer is caused by ultraviolet rays from the sun or tanning beds. UV rays can damage the DNA inside your skin cells, causing the unusual cell growth. Squamous cell skin cancer is also caused by UV exposure.
Squamous cell skin cancer can also develop after long-term exposure to cancer-causing chemicals. It can develop within a burn scar or ulcer, and may also be caused by some types of human papillomavirus .
The cause of melanoma is unclear. Most moles dont turn into melanomas, and researchers arent sure why some do. Like basal and squamous cell skin cancers, melanoma can be caused by UV rays. But melanomas can develop in parts of your body that arent typically exposed to sunlight.
Your recommended treatment plan will depend on different factors, like the size, location, type, and stage of your skin cancer. After considering these factors, your healthcare team may recommend one or more of the following treatments:
Knowledge Is Your Best Defense
What Is Skin Cancer?
Skin cancer is the out-of-control growth of abnormal cells in the epidermis, the outermost skin layer, caused by unrepaired DNA damage that triggers mutations. These mutations lead the skin cells to multiply rapidly and form malignant tumors. The main types of skin cancer are basal cell carcinoma , squamous cell carcinoma , melanoma and Merkel cell carcinoma .
The two main causes of skin cancer are the suns harmful ultraviolet rays and the use of UV tanning beds. The good news is that if skin cancer is caught early, your dermatologist can treat it with little or no scarring and high odds of eliminating it entirely. Often, the doctor may even detect the growth at a precancerous stage, before it has become a full-blown skin cancer or penetrated below the surface of the skin.
Americans will develop skin cancer by age 70.

Many Melanomas Dont Require Immediate Treatment
Many people have this concept that all melanomas are extremely rapidly growing cancers, says Dr. Marghoob. They think that waiting even one day after the diagnosis of melanoma can be fatal.
While some subtypes of melanoma do grow extremely fast, says Dr. Marghoob, most early melanomas dont require immediate treatment, allowing ample time to detect, treat, and cure them. Dr. Marghoob advises checking your skin on a monthly basis. If you notice a changing spot on your skin, dont delay in getting it checked out by a dermatologist, he says. And if your doctor does think you may have a melanoma, know that for most people its not necessary to rush to treatment. Most people can take the time they need to meet with doctors and understand their options.

Biological Therapies And Melanoma
Biological therapies are treatments using substances made naturally by the body. Some of these treatments are called immunotherapy because they help the immune system fight the cancer, or they occur naturally as part of the immune system.
There are many biological therapies being researched and trialled, which in the future may help treat people with melanoma. They include monoclonal antibodies and vaccine therapy.
How Serious Is My Cancer
If you have skin cancer, the doctor will want to find out how far it has spread. This is called staging.
Basal and squamous cell skin cancers don’t spread as often as some other types of cancer, so the exact stage might not be too important. Still, your doctor might want to find out the stage of your cancer to help decide what type of treatment is best for you.
The stage describes the growth or spread of the cancer through the skin. It also tells if the cancer has spread to other parts of your body that are close by or farther away.
Your cancer can be stage 0, 1, 2, 3, or 4. The lower the number, the less the cancer has spread. A higher number, like stage 4, means a more serious cancer that has spread beyond the skin. Be sure to ask the doctor about the cancer stage and what it means for you.
Other things can also help you and your doctor decide how to treat your cancer, such as:
- Where the cancer is on your body
- How fast the cancer has been growing
- If the cancer is causing symptoms, such as being painful or itchy
- If the cancer is in a place that was already treated with radiation
- If you have a weakened immune system

Why Does Skin Cancer Occur In More Non
Scientists dont fully know why people of skin with color develop cancer in non-sun-exposed areas, such as their hands and feet. They think that the sun is less of a factor though. However, dermatologists still see plenty of UV sunlight-induced melanomas and squamous cell skin cancer in people of color, in skin tones ranging from fair to very dark.
How Common Is Subungual Melanoma
Subungual melanoma is a very infrequent cancer, accounting for approximately 5% of all cases of melanoma. Usually, it is located on the thumb and the big toe. The average age of people affected by this type of cancer is between 60 and 70 years old. Then, subungual melanoma is a rare pathology that, due to a late diagnosis, it is complex to predict. Sometimes it is confused with a subungual hematoma, which is a common trivial pathology. Therefore, subungual melanoma is the most common type of melanoma diagnosed in highly pigmented individuals.

Symptoms Of Skin Cancer
Skin cancers arent all identical, and they may not cause many symptoms. Still, unusual changes to your skin can be a warning sign for the different types of cancer. Being alert for changes to your skin may help you get a diagnosis earlier.
Watch out for symptoms, including:
- skin lesions: A new mole, unusual growth, bump, sore, scaly patch, or dark spot develops and doesnt go away.
- asymmetry: The two halves of the lesion or mole arent even or identical.
- border: The lesions have ragged, uneven edges.
- color: The spot has an unusual color, such as white, pink, black, blue, or red.
- diameter: The spot is larger than one-quarter inch, or about the size of a pencil eraser.
- evolving: You can detect that the mole is changing size, color, or shape.
Basic Information About Skin Cancer
Cancer is a disease in which cells in the body grow out of control. When cancer starts in the skin, it is called skin cancer.
Skin cancer is the most common cancer in the United States. Some people are at higher risk of skin cancer than others, but anyone can get it. The most preventable cause of skin cancer is overexposure to ultraviolet light, either from the sun or from artificial sources like tanning beds.
Most skin cancers are caused by too much exposure to ultraviolet rays. To lower your risk of getting skin cancer, you can protect your skin from UV rays from the sun and from artificial sources like tanning beds and sunlamps.While enjoying the benefits of being outdoors, people can decrease skin cancer risk by using sun protection. Protect yourself by staying in the shade, wearing protective clothing, and applying and re-applying a broad spectrum sunscreen with a sun protection factor of 15 or higher.Links with this icon indicate that you are leaving the CDC website.
