If somebody has nodular melanomas or 6 or so years, will it visibly continue to grow in size?

If left untreated, would nodular melanoma continue to grow in 2.5 years? Is 3.5mm and hasn't grown.

Why are you waiting?: Melanomas grow and eventually metastasize. If you have a known melanoma it should be surgically removed as soon as possible with appropriate margins. At that depth, a sentinel lymph node biopsy is also advised. See a dermatologist or plastic surgeon as soon as you can. ...Read more

If I were to scratch off a melanoma would it visibly grow back before spreading to my lymph nodes/organs? How likely is it if it doesn't?

If I were to scratch off a melanoma would it visibly grow back before spreading to my lymph nodes/organs? How likely is it if it doesn't?

Unclear question: How do you know that you have a melanoma? Melanoma is a cancer of the skin. If you mean a mole, it is a bad idea to scratch it. If you have concern about melanoma, see your doctor. Please consult this site information on this topic: http://www.mayoclinic.org/diseases-conditions/melanoma/basics/definition/con-20026009 For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more

Can nodular melanoma be caught early with monthly skin exams? Or does it grow too quick? Seems many doctors misdiagnose it which causes problems.

Difficult : The reason why this type of melanoma is caught late because it spreads to the inside rather than spreading to the outside like other types of melanoma. Therefore, it is difficult to notice a change in the mile. Also, in melanoma, the deeper the lesion, the worse it is and the more likely to spread to other parts. This makes nodular melanoma more serious and aggressive as it grows deep. ...Read more

Had mole shaved and it was benign. Has grown back in 3 months. Can melanoma grow under a benign mole?

Had mole shaved and it was benign. Has grown back in 3 months. Can melanoma grow under a benign mole?

Yes but not usual: When a mole (or nevus) is shaved, frequently the depth of the shave is not deep enough to remove all of the melanin or pigment producing cells. This is why the lesion grows back. If instead, a full thickness excision is done, all of the involved skin is removed and the lesion will not re-grow. ...Read more

Does melanoma contine to grow and change on skin.  Just had mole removed dr feels aytipical no changes at least in last 2 years and seen four derms (6mth screenings) rounded flat dark brown 5-6mm mole?

Ugly duckling: No hard and fast rules about when to watch and when to cut. One way to decide is the ugly duckling principle. If one mole looks a lot different then the rest remove it. If a lot of abnormal moles take the worst, the one that is changing, or new. For sure remove if =/>7mm irreg shape > 2 colors fuzzy borders. There is also the willy factor. If it gives me the "willies" get it out. Good health ...Read more
