Does a Suddenly Raised Mole Always Indicate Melanoma?

If there is a suspicious mole that you are concerned about, it is always a good idea to have it evaluated and biopsied.

Melanoma sometimes is obvious on examination, and other times not.  A true diagnosis can only be obtained under the microscope.  Rapidly progressing moles, however, are more suspicious.

A suddenly raised mole does not always indicate melanoma.  In fact, a suddenly raised mole, in most cases, will not be melanoma.  There are several factors which can be signs of a potential melanoma, including size, color, and irregularity.  If you have a concern with your mole though, I would see a dermatologist to have it checked.  

Moles can change for many reasons and not all of them are malignancy. I always recommend that if a lesion on the skin appears suddenly, changes in any way, you should have it checked by a Dermatologist. This way, if it is worrisome, he or she can send it away for testing. This way it will alleviate your anxiety.
Good luck and I hope this answer was helpful.

Most pigmented lesions that suddenly rise generally are okay. While there is a chance, it can be a melanoma the chances are small. Consult with a dermatologist so he or she can evaluate to determine if a biopsy can evaluate. 

here's the good news...tiny moles the size of a pin prick are overwhelmingly okay...in fact the likelihood of a melanoma in something this size is almost nil...change can be due to any number of issues...if something is only 1-2 millimeters in diameter, I'd do nothing other than watch it for further changes...an old adage that's generally correct is that pigmented spots smaller than the diameter of a pencil eraser are not melanoma...the spot may not even be a mole...might be a small blood vessel...no harm in seeing a doctor if you're worried or if it continues to change...but overwhelmingly nothing to worry about...

Most pigmented lesions that suddenly raise are not melanomas; however, a small percentage might be. As such, the best option is to see a board-certified dermatologist to evaluate the lesion and determine whether a biopsy is necessary. If by chance it is a melanoma the prognosis is always better if the melanoma is detected and treated at as early a stage as possible.

Frequently we talk about the ABCDs of melanoma, which stands for Asymmetry, Border (irregular, jagged, blurred), Color (variation in color or any of the colors red, white blue or black) and Diameter (larger than the size of a pencil eraser). In addition we need to add an "E" to the "ABCDs". The "E" stands for Evolving (i.e. changing... getting bigger, darker, raised, or itchy, etc).

Since your pigmented lesion is changing or evolving, it should be examined by a dermatologist. Good luck.

Not always a problem, could be simply irritated. Suggest you get it checked out just to be completely sure its ok. A Derm can tell immediately if it needs to come off for a biopsy or not. Good luck

A suddenly raised mole is a changing mole and therefore it would be safer to have it evaluated by a board certified dermatologist. However, a mole that small is unlikely to be cancerous. Please use the ABCDE's as your guide for when to be concerned about moles: A for Asymmetry; B for Irregular Borders; C for Black or uneven Colors; D for diameter greater than a pencil eraser; and E for a growth that is Evolving or changing. If necessary, it is an extremely simple five minute procedure for a dermatologist to remove the mole using either a "punch" or a "shave" biopsy which typically leaves a minimal scar. The mole can then be checked microscopically for reassurance.
