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

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

Nope: Most moles are not cancerous, and will not turn into cancer. Melanomas are dangerous, and can look like a mole. Watch for moles w/ abcd's: a-asymmetry; b-irregular borders; c-different colors; d-diameber >6mm (size of pencil eraser). If you notice a mole like that, get it checked out asap. Any skin lesion which is growing, ulcerating, bleeding, or otherwise changing, get seen as well.

I have a mole on my left arm that feels bruised and the bruised feeling goes all the way around. Could this be a sign of skin cancer?

I have a mole on my left arm that feels bruised and the bruised feeling goes all the way around. Could this be a sign of skin cancer?

Probably not: There are many signs that could suggest that a mole could be cancerous. The usual signs of trouble are increasing size, change in coloration, bleeding, and change in shape. The sensation of "bruising" is not usually a sign of cancer. You should have this looked at by a qualified physician. Good luck!

Could white moles possibly be a sign of skin cancer?

Could white moles possibly be a sign of skin cancer?

Possible: It is not feasible to provide a meaningful answer without examining the lesions. However, basal cell carcinoma may present as a white nodule. It would be prudent to see a doctor for evaluation. 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.

What happens if you just ignore a skin cancer mole?

What happens if you just ignore a skin cancer mole?

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.

Almost seems like it can a regular mole, so what is the possibility of skin cancer?

Almost seems like it can a regular mole, so what is the possibility of skin cancer?

ABCD melanoma: When in doubt, ask your pmd to check on the mole for you to confirm. It will be suspicious if there is change in the size (gets bigger), looks asymmetric, has different colors, irregular border and if you have symptoms like bleeding, itches etc. The image here gives you an example how the melanoma looks like. However sometimes, the abnormality is not that dramatic. Ask your doctor to check it.

My mole keeps falling off do I have skin cancer? Is it normal for my mole to keep falling off? I never notice when it falls off

My mole keeps falling off do I have skin cancer? Is it normal for my mole to keep falling off? I never notice when it falls off

Not a mole: One considers by that a mole is a benign pigmented skin lesion that is a precursor of melanoma. When the first true mole appears it is a small flat lesion. This growth never falls off but rather continues to proliferate and grow in thickness. A pigmented keratosis can be misinterpreted as a mole and is characterized as a growth that can be picked or fall off the skin by mild trauma.
