I scratched off a mole when I was scratching my arm is it going heal back to the way it was?

I scratched off a mole when I was scratching my arm is it going heal back to the way it was?

Probably.: Different people have different concepts of what a "mole" is, so I'm not sure exactly what you scratched off. But in general, stuff you scratch off accidentally grows back without any problems. If it starts to itch, bleed, change color, or grow rapidly, that's another story, and you'll need to have a dermatologist take a look at it. ...Read more

Hi I caught my arm in a door and cut a mole off, it's hanging by a bit of skin, should I get it checked out or will it be ok? I have the mole 40 yrs. Thx

Should be fine: You should make sure the freshly exposed cut area is cleaned and covered to protect it from infection. The thread by which the mole is still hanging on will likely die and fall off due to lack of blood. ...Read more

Pre-cancerous mole on my arm. Just found out. What are my options?

Biopsy vs observe: I highly recommend a punch biopsy. This can be done by your primary care doctor, a surgeon, or a dermatologist. You can't really tell with 100% confidence if a mole is pre-cancerous based on its visual appearance. You have to examine it under the microscope. The other (poorer) option is to observe for changes in a few months. Take a high-quality digital photo with a ruler today for comparison. ...Read more

I just scratched a mole on my arm gently and it started bleeding, should I have it looked at?

I just scratched a mole on my arm gently and it started bleeding, should I have it looked at?

Yes: Don't want to alarm, but IMO any mole that misbehaves, including bleeding with minor irritation, should be taken VERY seriously. It is probably not melanoma, but this could be an early warning and you can never be too careful with this disease. It is a killer. And it can be cured if found and treated early. See someone and if they are unimpressed, ask why it bled and what if it IS a melanoma. ...Read more

A largish light brown mole has just appeared on my arm within a day, I'm 24, is there any reason for concern?

A largish light brown mole has just appeared on my arm within a day, I'm 24, is there any reason for concern?

Yes, get it checked!: How large? A mole approaching the size of a pencil eraser is suspicious, especially if it is growing or new. Moles with irregular borders, changes in color, different colors in the same mole, bleeding, itching, or large size are all signs of possible melanoma skin cancer. A dermatologist or primary care physician can check it out. Early detection of melanoma is key! ...Read more

You: You have mentioned two of the warning signs of melanoma (change in size and two different colors).

While I don't really have enough medical information to give you a diagnosis, considering that melanoma is one of the most deadly cancers, and the incidence has skyrocketed, the best and safest thing to do is see a dermatologist and have it biopsied as soon as possible. ...Read more
