Changes in Moles: When to Seek Dermatological Advice

Changes in moles

Dear Dr.
Wu,
I have the following questions to ask:
1.
There is a mole on my left arm that was originally 0.4 cm in size.
Its shape has changed, and it seems to have developed a "tail." After taking a close-up photo, I noticed that the color varies slightly, but not significantly, and the mole remains flat and not raised.
2.
Several years ago, I noticed a brown mole in the center of the sole of my right foot, approximately 0.2 cm in size.
Additionally, there is a black mole on the outer side of my left foot, about 0.3 cm.
Although neither has shown any color or shape changes and both are flat, I am still concerned about whether there is any issue.
3.
I have some very small red spots on my body that feel raised, but they are all smaller than 0.1 cm.
I am unsure if this is related.
Since I am currently on a business trip abroad, do these issues require immediate attention, or can I wait until I return home in two months for an examination?
Thank you!

Without actually seeing the lesion, it is impossible to determine.
If it is causing significant distress, please seek medical attention as soon as possible.

More Info

When it comes to changes in moles or skin lesions, it is essential to be vigilant and proactive about skin health. Your concerns regarding the changes in your moles and the appearance of new skin lesions are valid and warrant careful consideration.

1. Changes in Existing Moles: The first mole you described on your left arm, which has changed shape and appears to have a "tail," is particularly concerning. Any change in the shape, size, or color of a mole can be a warning sign of potential skin cancer, particularly melanoma. The asymmetry, irregular borders, and varied colors are classic indicators that should prompt further evaluation by a dermatologist. Even if the mole remains flat and does not protrude, the changes you noted are significant enough to warrant immediate attention.

2. New Moles: The moles on your feet, while they have not shown any changes in color or shape, should still be monitored. New moles that appear after the age of 30 or changes in existing moles can also be concerning. Although the moles you described are small and have not changed, it is still advisable to have them evaluated, especially since you are experiencing anxiety about them.

3. Small Red Dots: The small red dots you mentioned, which are less than 0.1 cm and feel raised, could be a variety of benign conditions such as cherry angiomas, which are common and usually harmless. However, any new or changing skin lesions should be assessed by a healthcare professional to rule out any serious conditions.

Given that you are currently abroad, it is understandable that you may be concerned about seeking immediate care. However, it is crucial to prioritize your health. If you can access a dermatologist in your current location, it would be wise to do so. Dermatologists can perform a thorough examination and, if necessary, a biopsy to determine whether any of the lesions are malignant. If you are unable to see a dermatologist immediately, keep a close eye on the moles and any changes that may occur. Documenting any further changes with photographs can be helpful for your healthcare provider later.

In summary, while some changes in moles can be benign, the changes you described—particularly the alteration in shape and the appearance of new moles—should not be ignored. Seeking dermatological advice as soon as possible is the best course of action. If you are unable to do so immediately, ensure that you schedule an appointment as soon as you return home. Remember, early detection is key in managing skin health effectively.

To determine whether a mole has undergone any pathological changes, a biopsy is necessary for a definitive diagnosis. If there are no changes in the short term, it is reasonable to monitor it; however, if there are significant changes, a biopsy should still be considered.
