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

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

Yes: Melanoma is a fairly aggressive malignancy with a significant history of metastasis a much more problematic issue than local growth. No one should have a melanoma left untreated for a 6 year time frame. I question wether you are referring to nodular basal cell carcinoma which also needs to be excised but does not have the metastatic potential. ...Read more

Skin Cancer (Definition)

Skin is the largest and one of the most complex organs in the body composed of hundreds of different structures. Nearly any of these elements can degenerate into cancer. However the three most common are: basal cell, squamous cell and melanoma which occur in that order and degree of aggressiveness. Although heredity plays a major role, sun exposure and tobacco use & ...Read more

Would nodular melanoma change in size and appearance if left untreated for 2.5 years?

Would nodular melanoma change in size and appearance if left untreated for 2.5 years?

It might: Any pathologist will tell you that the inside of a nodular melanoma is full of areas of rapid growth and usually areas where the tumor seems to be regressing. It's not incoinceivable that a nodular melanoma did not grow. If you have any suspicion that your mass is a melanoma or other cancer, ask to have it excised. ...Read more

Are melanomas usually a reddish pink irregular looking patch on skin? about the size of a pencil eraser?

Are melanomas usually a reddish pink irregular looking patch on skin? about the size of a pencil eraser?

Yes it can be: Most melanomas are mixtures of brown/black or tan color. Reddish pink would be uncommon. but watch for changes such as further enlargement in size or changes in color. If it gets bigger, get it removed. You could watch it for a few months and decide if it needs to be checked by your doctor in order to be certain. ...Read more

Is a skin tag with a base about the size of a dime cause for concern? The "tag" part takes up about 1/3 of the area. Can this turn to melanoma?

Is a skin tag with a base about the size of a dime cause for concern? The "tag" part takes up about 1/3 of the area.  Can this turn to melanoma?

Hmmmmmmm: Skin tags have small bases. They are pedunculated. A widely based skin lesion is not a skin tag. Any skin growth greater than 1 centimeter, or that is changing, should be checked by a dermatologist. Btw a dime is larger than a centimeter. ...Read more

What would cause a pet scan to not detect malignant melanoma that was about the size of a chocolate easter egg? I also have type II diabetes.

What would cause a pet scan to not detect malignant melanoma that was about the size of a chocolate easter egg? I also have type II diabetes.

Many Factors: No test is always right, pet/ct included. Every patient's tumor is unique, too. How a particular tumor will take up the primary pet/ct tracer, called f-18 fdg, is also not perfectly known. Some consistently fail to take up FDG that pet/ct is rarely used to image them, but this is not true for melanoma. Finally, smaller tumors are always harder to see, no matter which imaging technique is used. ...Read more

Will a melanoma always grow and change shape? I have a mole I'm concerned about only because it's somewhat new (2017) shape and size seems to be the same. Color got darker after I accidently scratched it off.. Hyperpigmentation maybe?

Have lesion examined: Never a bad idea to have such a lesion examined. While there might be some healing going on, better to have it evaluated early on. You can start with your primary care physician or a dermatologist. ...Read more

I noticed two flat brown/white spots, size of finger nail, in the center of my chest. Can Melanoma be flat and just appear on skin?

I noticed two flat brown/white spots, size of finger nail,  in the center of my chest.  Can Melanoma be flat and just appear on skin?

Possible: Get the areas biopsied. Most of the time melanoma is black and dark. But, I personally have seen very benign plain looking non-pigmented skin lesion come back as melanoma after biopsy. Melanoma / cancer does not play by the rules. Get checked. ...Read more

Button on the front appeared rapidly (4 weeks) skin color wt small symmetrical colored spots, bulging, roughened, mole size? Could that be a melanoma?

Get it seen: I suspect it'll turn out to be a keratoacanthoma but any growth that you have to ask about like this needs to be seen by your primary care physician. ...Read more

Picked off spot on palm of hand. It came back, shrunk to size of Pin prick and has moved. I'm a 21-year-old male. Melanoma? Going to doctor on 24th.

Likely a wart: From what you described, the lesion is more likely to be a wart than a melanoma. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. 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

Time to see doctor: Generally, a patient who had lymph node spread of a cancer and is only a few years out from treatment still has to keep monitoring for any possible recurrence. That can be stressful at times, because many people will get false alarms from symptoms that are not cancer recurrences. Sometimes symptoms do turn out to be bad. The only way to know is to evaluate symptoms such as enlarged immobile nodes. ...Read more
