Blackheads are not moles, nor will they ever turn into moles. While blackheads and moles can be similar in appearance, they are caused by very different things. Blackheads are a non-inflammatory form of acne, caused by an accumulation of sebum and dead skin cells that become stuck or clogged inside one of your pores.
A pimple on a mole might feel raised and tender to touch. Pimples can form deep in the skin as nodules or cysts, or closer to the surface as whiteheads, blackheads, papules, or pustules. A pimple on a mole might have a black or white top, or 'head,' but the darker color of the mole might make this difficult to see.
It's thought to be an interaction of genetic factors and sun damage in most cases. Moles usually emerge in childhood and adolescence, and change in size and color as you grow. New moles commonly appear at times when your hormone levels change, such as during pregnancy.
The cancerous spot felt like a lump on her chin, Cummins said, or like an "underground blackhead." But after several medical tests, doctors determined that the lump was actually squamous cell carcinoma, the second most common form of skin cancer after basal cell carcinoma.
Complications from a blackhead
If pores are infected, the skin can become inflamed and cause acne, which is the inflammation that results from clogged pores. The pores can also become inflamed if the blackhead isn't treated. Other conditions can occur as a consequence of the inflamed tissue if you pop pimples yourself.
When you have blackheads, these large pores become clogged with a substance known as sebum. A chemical reaction with the sebum occurs under your skin. Melanin is oxidized and turns the clogged pores a black color.
However, sometimes the whitehead or blackhead erupts deeper inside of the skin, causing large, tender, hard nodules or cysts under the skin that look like boils on the surface of the skin.
Stage 1: The cancer is up to 2 millimeters (mm) thick. It has not yet spread to lymph nodes or other sites, and it may or may not be ulcerated. Stage 2: The cancer is at least 1 mm thick but may be thicker than 4 mm. It may or may not be ulcerated, and it has not yet spread to lymph nodes or other sites.
Basal cell carcinoma is the type of skin cancer that most commonly may look like a pimple. The visible parts of basal cell carcinoma lesions are often small, red bumps that may bleed or ooze if picked at. This may look similar to a pimple. However, after it's “popped,” a skin cancer will return in the same spot.
The edges are irregular, ragged, notched, or blurred. The color is not the same all over and may include shades of brown or black, sometimes with patches of pink, red, white, or blue. The spot is larger than ¼ inch across – about the size of a pencil eraser – although melanomas can sometimes be smaller than this.
Moles, or nevi, typically form during childhood and adolescence, but new moles can appear in adulthood. Although most moles are noncancerous, or benign, the development of a new mole or sudden changes to existing moles in an adult can be a sign of melanoma. Melanoma is a type of skin cancer.
Normal moles
A normal mole is usually an evenly colored brown, tan, or black spot on the skin. It can be either flat or raised.
In Stage I melanoma, the cancer cells are in both the first and second layers of the skin—the epidermis and the dermis. A melanoma tumor is considered Stage I if it is up to 2 mm thick, and it may or may not have ulceration. There is no evidence the cancer has spread to lymph nodes or distant sites (metastasis).
Not only can you cause damage to your skin, but also, blackheads aren't as harmful to your skin as you might think. "It is very tempting to squeeze blackheads. Blackheads are dilated pores filled with keratin, or dead skin cells," Anna Guanche, board-certified dermatologist and beauty expert, told INSIDER.
Melanomas can be tiny black dots that are no bigger than a pen tip. Any new or existing moles that stand out from the rest in color, shape, or size, should be looked at by a physician.
However, squeezing out blackheads can create several problems: You may not remove the entire blackhead. You may even push the blackhead further into your skin, which can cause painful irritation. You may introduce bacteria or more oil into the blackhead opening.
A melanoma pimple will typically present itself as a firm red, brown or skin-colored bump that many doctors may misdiagnose as a pimple or harmless blemish. The main difference to note is that these bumps will not feel soft like a pimple, but rather will be firm or hard to the touch.
Basal cell carcinoma can appear as a flesh-colored, pearl-like bump – some would say looks like a pimple – or a pinkish patch of skin. They are commonly found on the head, neck, and arms, yet can form anywhere on the body, including the chest, abdomen, and legs.
A cancerous mole, or melanoma, is the result of damage to DNA in skin cells. These changes, or mutations, to the genes can result in cells growing rapidly and out of control. Melanoma is a type of skin cancer that occurs when pigment-producing cells known as melanocytes mutate and begin to divide uncontrollably.
Melanoma borders tend to be uneven and may have scalloped or notched edges, while common moles tend to have smoother, more even borders. C is for Color. Multiple colors are a warning sign. While benign moles are usually a single shade of brown, a melanoma may have different shades of brown, tan or black.
A mole that is asymmetric and/or has uneven edges can be a sign of melanoma. It may feel bumpy and/or rough to the touch – or you may feel a hard lump.
A mole that does not have the same color throughout or that has shades of tan, brown, black, blue, white, or red is suspicious. Normal moles are usually a single shade of color. A mole of many shades or that has lightened or darkened should be checked by a doctor.
A dilated pore of Winer is a noncancerous tumor of a hair follicle or sweat gland in the skin. The pore looks very much like a large blackhead but is a different kind of skin lesion. Dr. Louis H. Winer first described the skin pore in 1954, which is where the pore of “Winer” gets its name.
'You should absolutely not squeeze blackheads. Squeezing a spot can push the inflammation deeper and this can cause scarring of the skin,' she says. Squeezing a spot can push the inflammation deeper and this can cause scarring of the skin.
