Unfortunately, you can't tell by looking at a mole whether it's cancerous or what type it is. It could very well be a normal skin spot with an abnormal appearance. A dermatologist can't always tell the difference either.

In spite of that, how can you tell if a mole is bad?
It's important to get a new or existing mole checked out if it:changes shape or looks uneven.changes colour, gets darker or has more than 2 colours.starts itching, crusting, flaking or bleeding.gets larger or more raised from the skin.
Anyways, when should I be worried about a mole? If you have any moles that are larger than most, have smudgy or irregular edges, are uneven in colour or have some pinkness, you should see a doctor and get them checked. Any moles that appear newly in adulthood should be checked. The most concerning sign, however, is a changing mole.
Anyway, what are the chances of my mole being cancerous?
A study published in the Journal of the American Academy of Dermatology suggests around 7% of suspicious mole removals are cancerous. This number drops when accounting for all moles removed, as most are benign (non-cancerous).
What is a pre melanoma mole?
A precancerous skin lesion is a growth that can carry the same mutations present in fully manifested skin cancers, but to a lesser extent. The most common type of skin precancer is called actinic keratosis (AK).

Melanoma can grow very quickly. It can become life-threatening in as little as 6 weeks and, if untreated, it can spread to other parts of the body. Melanoma can appear on skin not normally exposed to the sun.
Also, when melanoma develops in an existing mole, the texture of the mole may change and become hard or lumpy. The skin lesion may feel different and may itch, ooze, or bleed, but a melanoma skin lesion usually does not cause pain.
Malignant melanoma, which starts out as a mole, is the most dangerous form of skin cancer, killing almost 10,000 people each year. The majority of melanomas are black or brown, but they can be almost any color; skin-colored, pink, red, purple, blue or white. Melanomas are caused mainly by intense UV exposure.
These types of moles should be monitored for drastic change, but generally aren't cause for concern. However, moles that change and become raised could be an indication of melanoma (as pictured above), and as mentioned previously, if a mole changes, seek advice from skin cancer specialist.
Causes of a painful mole. Even though pain can be a symptom of cancer, many cancerous moles don't cause pain. So cancer isn't a likely cause for a mole that's sore or tender.
An atypical mole is not a skin cancer but having these moles is a risk factor for developing melanoma. Although rare, melanoma can arise in association with atypical moles. That is why it is important to be aware of these moles, get them checked by your dermatologist, and watch out for changing moles.
If you see any of the following signs, contact your healthcare provider: A new, possibly large, irregularly shaped, dark brownish spot with darker or black areas. A simple mole that changes in color (particularly turning darker), size (growing), or texture (becoming firmer), and/or flakes or bleeds.
Yes, but a common mole rarely turns into melanoma, which is the most serious type of skin cancer. Although common moles are not cancerous, people who have more than 50 common moles have an increased chance of developing melanoma (1).
Funny-looking moles may look like melanoma but are actually harmless (benign) spots that don't need to be removed. However, if you have a few, particularly five or more of these funny-looking moles, your chance of getting a melanoma is increased.
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.
Atypical moles are often larger than other nevi (> 6 mm diameter) and primarily round (unlike many melanomas) but with indistinct borders and mild asymmetry. In contrast, melanomas have greater irregularity of color and may have areas that are red, blue, whitish, or depigmented with a scarred appearance.
Although it may not be serious, a mole that bleeds is a possible sign of melanoma — a rare but serious skin cancer that can spread if left untreated.
Redness or new swelling beyond the border of a mole. Color that spreads from the border of a spot into surrounding skin. Itching, pain, or tenderness in an area that doesn't go away or goes away then comes back. Changes in the surface of a mole: oozing, scaliness, bleeding, or the appearance of a lump or bump.
Survival for all stages of melanoma almost all people (almost 100%) will survive their melanoma for 1 year or more after they are diagnosed. around 90 out of every 100 people (around 90%) will survive their melanoma for 5 years or more after diagnosis.
They can change or even disappear over the years, and very rarely can become skin cancers. Some research suggests that having more than 50 common moles may increase one's risk of 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.
Diameter – most melanomas are usually larger than 6mm in diameter. Enlargement or elevation – a mole that changes size over time is more likely to be a melanoma.
