No, not all melanomas are cancerous. It’s important to understand the different types of melanoma in order to understand which ones can be cancerous and which ones cannot be cancerous.
There are two main types of melanoma: superficial spreading melanoma (SSM) and nodular melanoma (NM). SSM is the most common type in the United States and is often not cancerous. It occurs in the top layer of the skin, known as the epidermis, and tends to spread horizontally, making it the easiest to detect and treat.
It often can be cured with surgery if caught early.
NM is more dangerous because it tends to grow vertically and can penetrate deeper into the skin and spread to other parts of the body. It is usually more aggressive and can be more challenging to treat, making it more likely to be cancerous.
It usually requires a biopsy and can sometimes necessitate immunotherapy and radiation therapy.
In both cases, melanomas are usually identifiable by visual signs, such as an area of skin that is dark with irregular edges and darker areas around it. It is important to get these concerning spots of skin checked by a dermatologist if you notice any.
If caught and treated early, melanoma can often be cured.

Can you have melanoma without skin cancer?
Yes, it is possible to have melanoma without skin cancer. Melanoma is a type of skin cancer that develops from the pigment-producing cells known as melanocytes. These cells grow out of control, forming tumors or lumps under the skin.
While melanoma may start with the skin, it can develop in other parts of the body, such as the eyes, the intestines, or even inside the nerves. It is not always associated with skin cancer and can develop without any visible changes to the skin.
In some cases, the melanoma has already spread to other parts of the body before it is found on the skin. For this reason, it is important to have regular skin exams to detect any signs of skin cancer or melanoma as early as possible.
How do you know if you have non-melanoma skin cancer?
The most common signs and symptoms of non-melanoma skin cancer include:
• A spot or bump on the skin that is new, growing, or changing in size, shape, or color
• A sore that does not heal within four weeks
• Itching, bleeding, or pain in a sore
• A rough or scaly patch on the skin that may be red, yellow, or tan in color
• A bump that looks shiny and waxy or a bump with a flesh-colored or brown center
• A sore or bump that looks like a pink or red growth
If you notice any of the above signs or symptoms on your skin, it is important to consult with your doctor or dermatologist as soon as possible. They can perform a physical exam, as well as take a sample of the skin (a biopsy) and look at it under a microscope to determine whether it is cancerous.
Early detection and treatment of skin cancer is essential to successful treatment and avoiding complications.
What can be mistaken for melanoma?
Melanoma can sometimes be mistaken with other skin conditions or growths. Moles are the most common type of skin growths, and some moles can look like melanoma. Other skin growths such as a seborrheic keratosis (or “age spots”), cherry angiomas, and sebaceous hyperplasia can also resemble melanoma.
Differentiating these lesions from melanoma can involve an inspection of the lesion where one can look for specific characteristics that are different from melanoma. Melanoma can often have an irregular shape and border, and may be darker in color than the surrounding skin.
It also has the potential to grow or change quickly over time. However, differentiating between these skin growths and melanoma can be difficult, and it is important to have any suspicious lesions evaluated and monitored by a dermatologist.
What are the four early warning signs of melanoma?
The four early warning signs of melanoma, the most serious type of skin cancer, are known as the “ABCDE rule”.
A is for Asymmetry – one half of a suspicious spot is different from the other.
B is for Border – the edges of the spot or mole are irregular or jagged.
C is for Color – the spot or mole appears in multiple shades or multiple colors.
D is for Diameter – the size of the spot is larger than the size of a pencil eraser.
E is for Evolving – the spot or mole changes in pigment, size, shape, or texture.
Melanoma can also present as a brand new mole or a sore that does not heal. If any of these warning signs are present, medical attention should be sought. The earlier melanoma is caught, the better the chance of successful treatment and recovery.
How does your body feel when you have melanoma?
Having melanoma can cause a variety of physical symptoms, depending on where it is located on the body. Some common symptoms of melanoma include: changes in the appearance of a mole or other pigmentation on the skin; new growths on the skin; irritation and itching on or around the affected area; a feeling of firmness in the skin; pain or sensitivity in the affected area; and a lump or bump on the affected area.
Other symptoms may include: changes in the growth or discoloration of existing moles; bleeding or oozing from an existing mole; thickening of the skin in some areas; and development of flat, red spots.
In general, having melanoma can cause physical discomfort and potentially even pain. Further, unchecked melanoma can spread to other parts of the body and become more serious, potentially leading to more severe physical symptoms.
Therefore, it is important to get any mole or pigmentation changes checked by a doctor as soon as possible in order to detect the presence of melanoma.
What does melanoma look like when it first starts?
When melanoma first starts, it usually appears as an asymptomatic, pigmented lesion on the skin. It can appear in a variety of shapes and sizes, but is most commonly seen as a new spot or an existing spot that is changing in size, shape, color, or texture.
The lesion may have uneven edges, and be dark brown, black, or even red in color. On the face and body the initial lesion is typically flat, but can sometimes be slightly raised or bumpy and may range in size from a few millimeters to several centimeters.
It is important to note that melanoma lesion can also appear on other areas of the body, such as on the palms of the hands, soles of the feet, under toenails or fingernails, in the mouth or even around the eyes.
If you notice unusual changes in any spot on your skin, it is important to see your doctor for proper diagnosis.
Where does melanoma usually start?
Melanoma usually starts in the skin cells that produce melanin, which is the pigment that gives skin its color. Melanoma usually starts in an existing mole or in an area of normal looking skin. In the early stages, melanoma can look like a mole or a freckle that is changing in size, color, or both.
It may start as a small, dark spot with an irregular shape that may become raised or start to itch. It might also change in its color, becoming darker or multi-colored. In some cases, it can even look like a scar with some pink or red skin around it.
If you notice any changes in your skin that look unusual or are different from your other moles, you should have them checked by a dermatologist as soon as possible.
What are generally the first melanoma signs and symptoms?
The most common first signs of melanoma include changes in the size, shape, color, or feel of an existing mole. A mole or spot on your skin can suddenly change in size, shape, color, or feel; become itchy, tender, or painful; or bleed.
The ABCDEs of melanoma can help you remember what to look for:
A is for asymmetry: The shape of one half doesn’t match the other.
B is for border: The edges are ragged, blurred, or irregular.
C is for color: The color is not the same all over and may include shades of brown or black, sometimes with patches of red, white, or blue.
D is for diameter: The spot is larger than the size of a pea (about 6 millimeters).
E is for evolving: The mole is changing in size, shape, or color.
Other signs and symptoms of melanoma may include:
• A sore that doesn’t heal
• The spread of pigment from the border of a spot into surrounding skin
• Redness or a new swelling beyond the border of the mole
• Change in sensation, such as itchiness, tenderness, or pain
• Change in the surface of a mole – scaliness, oozing, bleeding, or the appearance of a lump or bump.
Is melanoma usually benign or malignant?
Melanoma is usually a type of cancerous (malignant) skin tumor. It is caused by an uncontrolled growth of pigment-producing cells called melanocytes, which can form tumors (benign or malignant) on the skin.
Melanoma typically appears as an abnormal mole or dark spot on the skin. If left untreated, melanoma can spread from the original site to other parts of the body. If caught early, melanoma can often be treated, making a full recovery more likely.
However, even in its early stages, melanoma can spread to other parts of the body, making it more challenging to treat. Therefore, it is very important to monitor the skin for signs of the disease and to speak with your doctor if any changes are noticed.
Are most melanomas benign?
No, most melanomas are not benign. Melanomas are a type of skin cancer that can be either benign or malignant. Benign melanoma does not typically spread to other parts of the body, whereas malignant melanoma can spread to other organs and parts of the body.
The American Cancer Society estimates that 5-10% of melanomas are benign, meaning that the majority of melanomas are malignant. It is important to have any suspicious moles or changes in the skin looked at by a doctor, as early detection is key when it comes to the treatment of melanoma.
Which type of melanoma has worse prognosis?
Of the four different types of melanoma, which is the most serious type and has the worse prognosis depends on various factors. In general, nodular melanoma is the most dangerous because it can spread rapidly and is more likely to grow into the deeper layers of skin.
It is also more resistant to treatment than superficial spreading melanoma (the most common type of melanoma) and acral lentiginous melanoma, another type of skin cancer. Lentigo maligna melanoma is the least deadly type, but it is still important to treat it quickly because it can spread to other areas of the body.
It is also important to closely monitor any changes in moles and skin lesions and seek medical advice if anything suspicious is detected. Early detection and treatment is key to improving the prognosis of any type of melanoma.
What does a benign melanoma look like?
A benign melanoma is a form of skin cancer that typically looks like a dark spot or mole on the skin but is not cancerous. Benign melanomas tend to be smaller than malignant melanomas and have an even pigment with a smooth and regular edge.
They most often appear as brown, black, or blue spots on the skin with shades that are similar in color throughout the spot. Generally, these are flat on the skin and can appear anywhere, but most commonly appear on the back, legs, and face.
In some cases, they may feel itchy, tender, or even bleed though they are otherwise mostly harmless.
It is important to pay attention to changes in moles or spots on the skin. If you notice a spot that changes shape, size, or color, or one that suddenly appears and is different from others, it is important to seek medical attention.
While the majority of moles and spots are benign, it is important to rule out any issues by talking to a doctor or dermatologist immediately.
What is the treatment for benign melanoma?
The exact treatment for benign melanoma, commonly referred to as nevi, depends on the size, shape, and location of the lesion. However, the general treatment is usually to surgically remove the lesion, either through excision, shave excision, or laser.
Excision is the most common method and involves cutting around the lesion and removing it. Shave excision is used for smaller, less-raised lesions, and involves use of a blade to shave off the lesion.
Laser is usually a last resort and involves using a laser to vaporize the lesion.
After the lesion is removed, the tissue is sent to a laboratory for analysis, where it is examined under a microscope to confirm the diagnosis. If the lesion is determined to be benign, no further treatment is usually needed.
However, it is still recommended that the patient schedules to see their doctor for regular skin exams, to ensure any suspicious lesions are caught early. In addition, it is important to avoid sun exposure and to use sunscreen if necessary to reduce the risk of furthering damaging the skin.
Does benign melanoma spread?
No, benign melanoma does not spread. It is a type of skin cancer that starts in the cells of the skin that produce melanin, the substance that gives skin its color. Unlike malignant melanoma, it is non-aggressive and non-invasive.
Because it is non-aggressive, it does not invade or spread to other parts of the body. Benign melanoma usually doesn’t require treatment. It can be monitored over time and may eventually go away on its own.
In some cases, a doctor may recommend removing the melanoma with surgery, as benign melanoma can become large or change in appearance over time. If a benign melanoma is growing rapidly, is in a sensitive area, or is causing other symptoms, a doctor may choose to remove it for both medical and cosmetic reasons.
