Does skin cancer always start from a mole?

Skin cancer . Malignant melanoma may develop from a preexisting mole or on "normal" skin. Other skin cancers such as basal cell or squamous cell skin cancer do not develop from preexisting moles . See a dermatologist for a skin cancer screening.
Skin Cancer and Mole. There are different types of skin cancer. A melanoma is a skin cancer that can start from a mole. The signs that a mole is cancerous could be a change in symmetry, shape, size, or color. Basal cell skin cancer and squamous cell skin cancer do not start from moles. All types of skin cancer are thought to increase in incidence with more exposure to ultraviolet radiation.

But bcc and scc, if not treated, can cause significant local tissue/skin disfiguring destruction. Read more...
Hard to know. Your phrasing makes the ? Difficult. Most likely you refer to melanomas, which often look like a dark mole. Technically, a mole has no cancer, and so won't ever spread. Melanomas will eventually spread and become life threatening, although how quickly that happens is varies widely. Some spread early by growing deep quickly, others may grow much more slowly. Best wishes. Read more...
Don't take a chance! If a mole or any lesion on the skin has been biopsied as a cancer you need to follow through with the recommended treatment. This usually is complete removal by surgical excision. Melanoma kills so have any concerning lesion checked by a dermatologist and if the biopsy comes back as an early melanoma have it excised as this is curative. Don't take a chance. Read more...

Is a mole always a sign that a skin cancer will develop?

No. Most moles are benign. Studies have shown that the more sun exposure you've had, the more acquired moles you will get; the more moles you have, the higher risk of developing malignant melanoma. However, most melanomas do not develop in pre-existing moles, though they are good mimics. This highlights the importance of routine self and md skin checks.

No. A true mole is not skin cancer nor is it always a precursor to skin cancer; however, certain skin cancers (melanoma) can have an appearance that mimics a mole. The abcde's of melanoma are: a = asymmetric shape, b = indistinct borders, c = multiple colors within the same lesion, d = diameter > 6 mm, and e = elevation. Always use sunscreen, re-apply often and have your skin checked by your doctor. Read more...

No. A mole is a cluster of mostly normal skin cells. However when you get a skin survey by a physician the moles are the first places that are checked. The pigmented moles are more likely to change in appearance in such a way that cancer will be suspected and a biopsy done. The vast majority of moles will never degenerate into skin cancer.

Most moles are fine. Fortunately, most moles or nevus are benign (not cancerous). Melanoma is a type of skin cancer that can develop from existing moles or in a new area. Just because you have moles doesn't mean you have skin cancer, though patients with a lot of moles (more than 50) that are unusual in appearance may be at higher risk and should be checked regularly to make sure they are not changing.

Look for unusual change in shape, color, symmetry, border, size, bleeding, itching, new moles or lesions & see a dermatologist. Read more...
Nope. Most moles are not cancerous, and will not turn into cancer. Melanomas are dangerous, and can look like a mole.
