Mole under the nose

The appearance of moles under the nose is due to long-term interference of pigments and failure to clean them in time. Generally, there are several types of cleaning methods. If they are within the removable range, they can be treated with laser. Some moles cannot be removed, so they can be covered with concealer when wearing them.

The following types of moles should be removed:

1. Moles that are susceptible to long-term friction irritation, such as moles located where you wear a bra and on your waist.

2. Moles that show atypical changes. Moles with atypical appearance may become malignant, such as very dark moles, uneven pigmentation (variegated), uneven or irregular edges, unclear boundaries, left-right asymmetry, and statistically larger than 5 mm in diameter.

3. A single mole changes suddenly and rapidly. If moles all over the body change at the same time due to hormonal changes, there is less cause for concern. However, if a single mole changes suddenly and rapidly, it is worth paying attention to.

4. Moles growing in special parts. If you have moles on the extremities (hands or feet), you must pay close attention to them because moles in these places are more likely to turn into malignant melanomas than moles in other places.

5. Moles of mucous membranes. Black moles on the oral mucosa, conjunctiva, vagina, and the part of the foreskin that is turned out.

6. Mole in the nail groove. The nail groove is connected to the skin under the nail and may grow under the nail and be blocked by the nail, making it difficult to see the changes. Moreover, if it grows at the extremities, it is more likely to become malignant in the future.

7. Some moles are inherently high-risk moles. Moles that can be seen when a baby is born are called congenital moles. There are not many congenital moles. According to statistics, 1% of newborns have moles. Not all congenital moles are dangerous at birth. Size is an important factor. Generally speaking, the larger the mole, the greater the chance of it becoming malignant in the future, so doctors recommend that it should be removed as soon as possible.

Some people have a keloid-prone constitution, in which scar tissue will proliferate abnormally, resulting in hypertrophic scars. Keloid pedis often occurs on the earlobes, shoulders, upper arms, chest and back, but not on the face. If people with this physical condition want to remove moles for cosmetic purposes, they should first inform their doctor of their physical condition to avoid getting big scars in return.

Dangerous malignant melanoma

Ou Shengyun, a plastic surgeon at Taipei Mackay Memorial Hospital, said that the symptoms of a benign mole turning into a malignant melanoma are: bulging, extremely dark pigmentation, itching, pain, bleeding and ulceration.

There are three main types of skin cancer: malignant melanoma, basal cell carcinoma, and squamous cell carcinoma.
